When your engine suddenly shuts off, the road transforms from routine to risk in seconds. Understanding why this happens can save your car and your safety. So what triggers these unexpected failures?
If the fuel filter, pump, injectors, or fuel lines become clogged, the amount of fuel reaching the engine becomes insufficient, leading to sudden engine shutdown.
One of the most common and straightforward reasons for a car to stop while driving.
When these components fail, the combustion process inside the engine cannot be completed, causing the vehicle to stop.
Accumulated dust and debris reduce the amount of oxygen needed for combustion, which may cause the engine to stall.
A failing battery may not provide the necessary power to operate essential vehicle components, resulting in engine shutdown while driving.
When the engine temperature exceeds the normal range, it may shut down suddenly. This is a serious issue that can threaten the safety of the vehicle and its occupants.
When the AC is turned on, the system requires additional power to operate the compressor and fan. If the battery is weak, it may not handle the extra load, causing the engine to stall.
If the alternator is not charging the battery efficiently, the vehicle may experience a power shortage, leading to engine shutdown.
Problems such as low refrigerant pressure or compressor malfunction increase the load on the engine, which may cause it to stop.
Turning on the AC increases engine load. If the cooling system is weak, the temperature may rise abnormally, causing the engine to shut off.
A clogged fuel filter or weak fuel pump may fail to supply enough fuel. When the AC is activated, fuel consumption increases, potentially causing the engine to stall.

Vehicle ownership transfer in Saudi Arabia is done electronically through the vehicle sale service on the Absher platform, without visiting traffic offices: the seller enters the buyer's ID number and date of birth, the agreed sale price and the seller's bank account; the buyer then receives a notification of the request within one hour and accepts or declines it, transfers the price through Absher's secure payment system, insures the vehicle and pays the fees, and once the car is received, checked and the delivery is confirmed on Absher, ownership is officially transferred. Both parties must be registered on Absher, the vehicle registration (istimara), periodic inspection and insurance must be valid, and there must be no violations on the buyer or the vehicle.
The Ministry of Interior offers the vehicle sale service through the Absher platform, and the National Platform describes it as a service that enables individuals to sell their private vehicles and transfer ownership electronically after its dues are cleared, after reaching an agreement with the buyer and completing all required procedures, including vehicle inspection to ensure compliance with conditions, registering the vehicle under the buyer's identity, and issuing the vehicle registration license.
Procedures and conditions may be updated from time to time, so confirm the latest steps on the Absher platform or the National Platform before you start.
Before the seller starts the request, both parties should review the conditions listed on the service page on Absher, as failing to meet any of them may stop the sale:
The page also mentions limits on the number of vehicles of certain types that a resident may own, so review them on Absher if the buyer is a resident. If the periodic inspection is close to expiring, prepare the car early using the checklist on how to prepare your car for the periodic inspection.
After agreeing with the buyer on the price and other terms, the seller starts the request with these steps, as set out by the National Platform:
Ownership does not pass to the buyer until they complete their steps on the platform, which according to the National Platform are:
The table below summarises the role of each party at every stage of the sale:
| Stage | Seller | Buyer |
| Before starting | Agree on the price and terms, and check the istimara, periodic inspection and insurance are valid | Register on Absher and make sure there are no violations on them |
| Creating the request | Enter the buyer's ID, date of birth, price and bank account, then confirm | Wait for the Absher notification |
| Responding | Wait for acceptance or refusal | Review the details and accept or decline the request within one hour |
| Payment | Receive the price in the bank account entered in the request | Transfer the price through Absher's secure payment system |
| Insurance and fees | The platform lists no step for the seller at this stage | Insure the vehicle and pay the government fees and Absher fees |
| Delivery | Hand the vehicle over to the buyer after they accept the sale | Receive and check the vehicle, then confirm delivery on Absher |
If you are handing your car over to a family member, Absher has a separate service called vehicle ownership transfer between family members, which allows vehicle ownership to be waived between family members electronically once the current owner and the new owner agree. The National Platform lists its steps as follows:
The platform organises the procedure, but it does not replace inspecting the car yourself; the service page on Absher states that the sale takes place after the vehicle has been viewed and inspected and the seller and buyer have agreed. Here are practical tips before accepting the request:
Transferring car ownership through Absher is a clear process if you prepare for it: check the conditions, agree on the price, inspect the car before accepting, pay through the platform's secure payment system, and do not confirm delivery before checking the car. If you are looking for your next car, you can browse the cars available at Saleh Cars Group.

A Mojaz report helps you read a used car’s history through the records available; it does not deliver a final verdict on its condition. Start by matching the vehicle’s identity, then read mileage, accident and maintenance records chronologically and compare them with documents and the car’s current condition. No accident record does not mean accident-free, and missing mileage readings do not validate the odometer. Use the report to identify seller questions and professional inspection priorities before deciding to buy, not as a replacement for inspection.
The official Mojaz homepage (in Arabic) says it brings together key historical vehicle data from official sources in one report. Its report outline lists vehicle information, odometer reading history, accident records, maintenance and repairs, warranty information, spare parts, vehicle reputation and related images.
These are section names presented by the service, not a promise that every section contains data for every car. Read what is actually available, and do not turn a blank field into a positive or negative finding. Likewise, do not infer a specific rating or acceptance standard from the vehicle reputation heading; use any accompanying explanation and ask about unclear descriptions before relying on them.
Before discussing findings, establish that the report belongs to the actual car being offered. Ask to see the full version rather than a cropped image of a reassuring section, and match its identification details to the vehicle documents and the car. Do not rely on a similar colour or general description, or dismiss an identification mismatch as a minor error without checking.
For identification details and their locations, see the guide to vehicle identification numbers, while paying attention to the name of each identifier in the document you are reading.
Read the date of each distance reading, not just the last number. Put the available readings in order from oldest to newest, then compare the latest with the car’s odometer during the viewing. Check measurement units first; do not directly compare figures expressed in different units. Your aim is to understand the sequence and identify questions, not estimate true mileage from cabin appearance alone.
If the seller mentions an odometer replacement, ask for the work record and evidence of readings before and after replacement, if available. Do not fill a missing sequence with estimates or treat consistent readings alone as a guarantee that the entire usage history is known.
If an accident record appears, read its details as written and compare them with repair documents supplied by the seller. Do not reduce the assessment to a record count or label damage minor or severe without supporting information. A report may describe a historical event, while repair quality and present condition need an independent inspection.
If related images appear, check their connection to the event, the vehicle and their date whenever that information is available. A photograph does not reveal everything behind visible parts, and missing images do not rule out damage. Where structural repairs are suspected, request a specialist inspection. The guide to signs of bodywork and structural repairs can help you frame questions, not make your own technical verdict.
If no accident record appears, the accurate wording is: no event is visible in the data you are reading. Do not replace that with the car has never had an accident, or let that inference cancel the inspection or the request for repair documents.
Read available maintenance and repair entries with their dates, comparing them with the seller’s invoices. Distinguish a record of past work from proof that the relevant system works well today. If a repair description recurs, ask what was done and what happened afterwards, without automatically assuming a particular fault or an unsuccessful repair.
Warranty information alone does not mean cover is active or transferable to you; verify the document and terms with the relevant provider. Equally, do not infer from a spare parts section that every component is genuine or in good condition. A missing maintenance record does not prove neglect, but leaves a question requiring documents and inspection.
Compare documented work with the appropriate owner’s manual requirements alongside a professional. Do not derive a new servicing schedule from the report or assume one completed job means all other scheduled work was done or related components are sound.
Use this table to organise your notes; it is not a real sample vehicle report. Always distinguish what you read, what you still do not know and the next step needed to close that gap.
| What you read | What it does not prove alone | Next step |
| Consecutive odometer readings | Complete mileage history | Compare with the odometer and documents |
| No odometer readings | Accuracy of current mileage | Seek more evidence and document the gap |
| An accident record | Current repair quality | Repair documents and specialist inspection |
| No visible accident record | An accident-free car | Professional body and paint inspection |
| Recorded maintenance work | The component’s condition today | Compare with the current inspection |
| Warranty information | Active cover for the buyer | Verify terms with the relevant provider |
Start with an open question about the car’s usage history, then address unclear report entries. Request specific answers that can be connected to documents; personal trust or numerous photographs are not substitutes for verification. Keep your notes separate from the original report so your interpretations do not become confused with its records.
Give the professional your report and notes before inspection, and request an assessment of the current structure, mechanical and electrical systems and safety components. Do not simply seek confirmation of an existing impression: ask what was checked and what could not be verified. To organise the rest of the viewing, see the used car inspection tips before purchase.
If a material identity or mileage discrepancy appears, or a significant repair remains unexplained, postpone the decision until it is clarified. If the gap cannot be closed, treat it as unknown information rather than proof of sound condition. Once the technical assessment is settled, review the vehicle ownership transfer steps on Absher separately; a history report does not replace the sale procedures.
In short, read a Mojaz report as available evidence and open questions, not a certificate that the car has no defects. Match its identity, review the timeline and connect the findings with documents and an independent inspection. A stronger decision clearly distinguishes what is established from what remains unknown.

Accident damage assessment is a step you may need after a Najm or traffic police report. According to the Saudi Authority for Accredited Valuers (TAQEEM), it means determining the cost of repairing the vehicle, including parts, or estimating its market value before or after the damage. These assessments are managed electronically through the Taqdeer system, which operates under the Authority’s supervision and lets you book an appointment and check the status of your assessment. This guide covers the stage after the report: when to seek an assessment, what to prepare, how to read the report and review it with your workshop and insurer, and what to do if you disagree with the result.
On its official English website, TAQEEM describes vehicle damage assessment valuation as “the act or process of determining the value of repairing the vehicle including the spare parts, or estimating the market value of the vehicle before and after the accident”; the Arabic version also mentions labour explicitly. The outcome may therefore be a repair cost, or a market value before or after the damage, depending on the case.
TAQEEM describes Taqdeer as “an online integrated system for managing, operating, and organizing vehicle damage assessment processes” and lists “Book an appointment at Taqdeer centers” among its services. The Taqdeer system website (in Arabic) states that it operates under the supervision of the Saudi Authority for Accredited Valuers. An assessment is a technical valuation of the damage; it is neither the accident report nor your insurer’s decision.
The sequence starts with attending to and documenting the accident. If you have not completed that stage, begin with the guide to Najm reporting steps and when to call the traffic police, then return to this guide.
The official pages we relied on do not state that an assessment is required for every accident, nor do they describe the content of report messages. Follow what the accident report and your insurer require in your case, and ask before any repair starts, because repairing damage before it is assessed may cost you the chance to document it as it was. Useful questions for your insurer:
The Taqdeer website presents the service in three consecutive stages, which can be summarised as follows:
If your plans change before the appointment, the manage bookings service allows you, according to the site, to modify or cancel the booking, and the assessment centers page helps you find the nearest centers in your city. We do not mention numbers of centers, timings or fees here; follow what the service shows for your case when you book.
The pages we reviewed do not publish a document list, so the list below is practical rather than an official requirement; what the booking screen and center ask for takes precedence:
Do not repair the damage being assessed before the appointment unless the relevant authority tells you to, and do not drive an unsafe car; arrange transport if you notice a leak, a red warning light or a steering fault.
The report format may vary from case to case, but the Authority’s definition shows what it centres on: labour, spare parts, or market value before or after the damage. Use the table to review it item by item:
| Item | What to Check | What to Ask |
| Vehicle and accident details | The car and the accident reference match | Do these details relate to my car and this accident? |
| Spare parts | The listed parts compared with the documented damage | What type of part does the assessment assume? |
| Labour | Listed work such as bodywork and paint | Does the work cover all the damage I documented? |
| Market value | Whether a value before or after the damage is stated | On what basis was this value reached? |
To understand how the type of part affects a repair, see genuine vs aftermarket vs used car parts. Do not assume the report specifies the type of part unless it says so explicitly; ask about it.
The assessment sets a value, while the compensation and repair path is governed by your policy and your insurer. Check your policy type and what it covers in the guide to comprehensive versus third-party car insurance, and do not assume that the assessed amount is what you will receive in every case.
If the car needs sensor or camera calibration after the repair, ask whether it is included in the assessment or in the workshop’s quote.
We did not find a published objection mechanism for assessment results on the official pages we reviewed, so we do not describe a specific procedure. The right step is to ask the source about the official procedure:
Do not accept a settlement you disagree with before you understand its consequences, and ask for written replies where possible.
The report and invoice help you later when you sell the car or when a buyer asks about the accident. The guide to reading a Mojaz report and its limits explains how accident records in a vehicle history should be understood and what cannot be concluded from them.
If you are a buyer looking at a car with signs of repair, ask for the assessment report and invoice if they exist, and use the guide on how to tell whether a car has been repaired alongside an independent technical inspection.
No. The report documents the accident, while the assessment estimates the repair cost or the market value of the vehicle before or after the damage.
Do not rely on a general rule; follow what the accident report and your insurer require in your case, and ask them before repairing the car.
The Taqdeer website offers an assessment status inquiry service and lists receiving the report electronically as one of the service stages.
The website offers a manage bookings service for changes and cancellations; follow what the service shows for your booking.
Not necessarily. Compensation depends on your policy and your insurer’s procedures, so ask your insurer how it is calculated in your case.
After the report, ask your insurer what your case needs, book the assessment through the official system and read the report item by item before any repair. If you disagree, ask Taqdeer and your insurer about the official procedure, and keep your documents for the future.

Car brand logos are the badges and names each manufacturer places on the front grille, the boot lid and the centre of the steering wheel, and the easiest way to learn them is to group them by country of origin: Japanese badges such as Toyota's three ovals, Korean ones such as Hyundai's slanted H, and Chinese brands, many of which spell out their full name in Latin letters, alongside German, European and American badges. In this guide you will find each brand's name as it is written and said, a short description of its badge, its meaning where it is documented, and a table for quick comparison.
A car badge (the logo or emblem) is the trademark that identifies the manufacturer, and it usually appears in several places:
Badges fall into two types: a standalone symbol such as a star, rings or a lion, or a name spelled out in letters, as with many American and new Chinese brands, and knowing this difference helps you recognise a car from a distance.
Japanese badges are very familiar on the Kingdom's roads, and most are simple symbols that are easy to remember:
Chinese cars have become familiar in the Saudi market, and their best-known badges include:
Many Chinese brands have appeared in recent years, some cannot be recognised from the badge alone, and here are practical ways to tell them apart:
European badges often rely on old symbols with well-known stories:
American badges tend towards written names and simple shapes:
A quick summary of each brand's badge:
| Brand | Country of origin | Badge description |
| Toyota | Japan | Three ovals |
| Nissan | Japan | Name inside a thin circle |
| Honda | Japan | Upright letter H |
| Mitsubishi | Japan | Three red diamonds |
| Hyundai | Korea | Slanted H in an oval |
| Kia | Korea | The word KIA in a sharp script |
| Changan | China | V shape inside a circle |
| Chery | China | A-like symbol in an oval |
| Jetour | China | Name in Latin letters |
| Haval | China | HAVAL in large letters |
| MG | Britain (Chinese owner) | MG inside an octagon |
| BYD | China | The letters BYD |
| Mercedes-Benz | Germany | Three-pointed star in a circle |
| BMW | Germany | Circle with blue and white quarters |
| Audi | Germany | Four interlinked rings |
| Volkswagen | Germany | VW letters in a circle |
| Peugeot | France | Lion |
| Ford | USA | Blue oval |
| Chevrolet | USA | Gold bowtie |
| GMC | USA | Red GMC letters |
Car brand logos become easier to remember when you link each badge to its country and parent company, read the name written on the boot when in doubt, and check the registration card and the VIN before any purchase decision. You can browse the cars available at Saleh Cars Group to get to know the different brands and models.

If you are asking when to replace car tyres, the short answer is: replace a tyre when the surface of the tread reaches the level of the raised wear indicators inside the grooves, when a bulge, a deep cut or clear cracks appear in its sidewall, or when the rubber has aged to the point at which the tyre or car manufacturer recommends replacement, even if the tread looks good. In this guide we explain how to check your tyres, what the wear pattern reveals, and how to choose the right replacement.
Replacement is not tied to a single distance for every car, but to the tyre's condition and its maker's recommendations. The main signs are:
Inside the grooves are small raised bars called wear indicators, whose location is marked by the letters TWI or a small triangle on the tyre's shoulder, and when the tread surface is level with them, the tyre has reached the end of its usable life. To check:
Do not wait until they are exactly level if you travel often or drive in the rain, as water clearance and grip weaken gradually as the tread gets shallower.
The sidewall flexes with every turn of the wheel and carries the car's weight, so any damage to it is more dangerous than tread wear:
The wear pattern reveals the cause of the problem, and if you do not fix it, new tyres will wear the same way:
| Wear pattern | Likely cause | What to do |
| Both edges more than the centre | Pressure lower than recommended | Set the pressure according to the driver's door sticker and check it regularly |
| Centre more than the edges | Pressure higher than recommended | Set the recommended pressure, not the maximum pressure printed on the tyre |
| One inner or outer edge | Wheel alignment or suspension fault | Check the alignment and suspension parts |
| Diagonal, feather-like wear | Incorrect toe between the two wheels | Have the alignment set at an equipped workshop |
| Repeated patches or scallops | Unbalanced wheels or worn shock absorbers | Balance the wheels and check the shock absorbers |
| A single flat spot | Hard braking with a locked wheel, or standing a long time without moving | Have a specialist assess the tyre |
If you see wear on both edges, start by reviewing the causes, signs and solutions for low tyre pressure, and if the wear is on one edge or comes with the car pulling to one side, read about the difference between wheel balancing and alignment.
Rubber ages over time even if the car is used little, and you will find how to tell a tyre's age from the DOT code in our article on how to read tyre size and manufacture date. There is no single lifespan for all tyres, so refer to the tyre and car makers' recommendations. In the Kingdom's climate, some factors speed up deterioration:
Ideally all four tyres match, but replacing them all together is not always necessary:
The spare forgotten in the boot ages just like the other tyres, even if it is never used:
Choose what your car was designed for, not just what the shop has in stock, and check the following:
The Saudi Standards, Metrology and Quality Organization offers the Energy Efficiency Label for Tires service, and explains that the label serves as a guide for consumers before purchasing the product to increase their awareness of its energy efficiency before buying it.
The organization lists tyres among the products subject to the efficiency label regulations, and the aims of these labels include reducing energy consumption for the consumer, enabling the consumer to know a product's efficiency before buying, and protecting consumer safety and health and the environment. In practice:
Checking your tyres takes only minutes: look at the wear indicators, inspect the sidewall, notice the wear pattern and read the manufacture date. If a danger sign appears, do not postpone the change; choose a replacement with the recommended size, load and speed ratings, then fix the cause of any uneven wear.

Vehicle driving authorization on Absher is an electronic service that lets a vehicle owner add an authorized person to drive the vehicle inside or outside the Kingdom, depending on the type of authorization selected. The owner starts from Vehicles, then Manage Vehicles, selects the vehicle, chooses Authorize Vehicles and then Issue Authorization. Before that, the vehicle registration must be valid with active insurance, and both parties must have Absher accounts. This guide covers the conditions, steps, period limits, the difference from ownership transfer and what the owner should check first.
The official Issue an Authorization service page on the National Portal says the service allows you electronically to add an authorized person to drive a vehicle inside or outside the Kingdom, depending on the selected type of authorization. The service belongs to the Ministry of Interior, targets individuals, both citizens and residents, and lists its channels as the website portal and the iOS and Android apps.
The authorization is therefore permission to drive, not a sale or a transfer of ownership. The vehicle owner issues the authorization, and the authorized person is added to drive within the selected type and period. Read the service name in your account carefully and do not confuse it with other vehicle services in the same menu.
The Prerequisites tab of the official service page lists the following conditions, as shown at the time of writing:
The Required Documents tab lists the following:
The text we reviewed adds no other conditions, so follow what the service requests for your case rather than lists circulating in forums or messages.
The following steps come from the official service page. Menus may look different in the portal and the app, so look for the same names:
The page describes the service duration as immediate, but do not rely on pressing the issue button alone; review what the service displays after submission to confirm the transaction is complete. If a message prevents issuing the authorization, return to the conditions above and start with the item the message refers to, such as insurance validity or the validity of one of the licenses, instead of retrying without changing anything.
The page states that the authorization applies inside or outside the Kingdom depending on the type of authorization you select in the final step. Decide the purpose before you start: will the authorized person drive only inside the Kingdom, or do they need to drive the vehicle abroad?
For an external authorization, the Required Documents tab requires the authorized person to hold an exit and re-entry visa. The page links the visa duration to the authorization period, but the Prerequisites wording (the authorization period must not exceed the visa duration) runs in the opposite direction to the Required Documents wording (the visa must not exceed the authorization period), so follow what the service accepts for your case. A holder of a final exit visa cannot be added as an authorized person.
The service page does not address the requirements of other countries or border crossings when travelling by car, so ask the competent authorities about this before relying on the authorization alone.
The service page does not set a fixed authorization period; it sets upper limits instead. The period must not exceed the validity of the vehicle registration, the validity of the authorized person’s driving license, or the duration of their exit and re-entry visa if they hold one. In practice, whichever of these dates expires first limits the period you can choose.
As for cancellation, the pages we reviewed do not explain the steps. Start from the Authorize Vehicles screen in the owner’s account and review the options shown to you. If nothing fits your case, ask the official Ministry of Interior support channels, and do not rely on an unofficial explanation that mentions a specific button or period.
If the vehicle registration is about to expire, review the vehicle registration renewal steps on Absher before choosing the authorization period, because the period may not exceed the registration validity.
Some people confuse allowing someone to drive the car with selling it to them. As the service describes it, authorization adds an authorized driver and is issued by the vehicle owner, while ownership transfer is a separate procedure that changes the owner. The table summarises the difference:
| Item | Driving Authorization | Ownership Transfer |
| Purpose | Add an authorized person to drive the vehicle | Transfer vehicle ownership to another owner |
| Who starts it | The vehicle owner, according to the service page | According to the sale service conditions |
| Does the owner change? | The service describes no change of ownership | Yes, that is the purpose of the procedure |
| Period limits | Not beyond the registration and the authorized person’s driving license validity | Follows the transfer service conditions |
If your aim is to sell or buy the car, authorization is not a substitute for a sale; review the Absher ownership transfer steps and sale conditions to complete the correct procedure.
The official conditions determine whether the authorization can be issued, but they do not answer every practical question. Before issuing it, review the following points:
If an accident happens while the authorized person is driving, learn the steps to take after a car accident and Najm reporting. The service page does not address how responsibility for accidents or violations is shared between the owner and the authorized person, so do not build assumptions on it; ask the competent authority or your insurer about your case.
Yes. The Required Documents tab states that the authorizer must be the vehicle owner. The authorization is therefore not issued from the account of someone who does not own the vehicle, even if they usually drive it.
Yes. The page requires both the authorizer and the authorized person to have Absher accounts. Confirm this before starting so the process does not stop when you enter the details.
No. The prerequisites state that authorization cannot be granted to someone holding a final exit visa. For a holder of an exit and re-entry visa, the authorization period is tied to the visa duration.
The published condition is a valid vehicle registration with active insurance. If either has expired, resolve it first and then return to the authorization service.
The service page mentions insurance only as a condition for issuing the authorization. Review your policy and its terms with your insurer before allowing another person to drive.
Vehicle driving authorization on Absher starts from the owner’s account and requires a valid registration, active insurance and Absher accounts for both parties, with its period limited by the validity of the licenses and visa. Choose the right authorization type, review your insurance policy and do not use authorization as a substitute for ownership transfer.
