BYD Sealion 7 MOT failure rates: what to expect
What fails on a BYD Sealion 7 at MOT, how often, and what each fix typically costs.
Updated 4th September 2026
The BYD Sealion 7 has shown a few common issues that can lead to MOT failures. The most frequent problems include issues with brakes, lights, suspension, and emissions. Fixing these problems can vary in cost, but understanding them can help you prepare for your next MOT.
Brake System Failures
Brakes are a critical safety feature, and issues with them are among the most common reasons for MOT failures on the BYD Sealion 7. Problems can arise from worn brake pads, damaged discs, or issues with the brake fluid.
Regular maintenance can help prevent these issues and ensure your brakes are in good working order.
Lighting Problems
Lighting issues are another frequent cause of MOT failures. This includes problems with headlights, brake lights, and indicators. A blown bulb can lead to an automatic failure, making it essential to check all lights before your MOT.
Ensuring all lights are functioning properly can save you from unexpected failures.
Suspension and Steering Issues
The suspension and steering systems on the BYD Sealion 7 can also lead to MOT failures. Common problems include worn shock absorbers, damaged springs, or issues with the steering alignment. These components are vital for safe handling and ride comfort.
Regular checks can help identify these issues early, preventing costly repairs down the line.
Emissions Control Failures
Emissions testing is a crucial part of the MOT process, and failures in this area can be particularly concerning for drivers of the BYD Sealion 7. Common issues include faulty catalytic converters, exhaust leaks, or problems with the engine management system.
Keeping your engine well-maintained can help reduce the likelihood of emissions-related failures.
Tyre Condition and Tread Depth
Tyres are another common area where the BYD Sealion 7 can fail its MOT. Inspectors will check for tread depth, sidewall damage, and overall tyre condition. The legal minimum tread depth in the UK is 1.6mm, and anything below this can lead to an automatic failure.
Replacing tyres can vary significantly in cost, depending on the brand and size. Regularly checking tyre pressure and tread depth can help ensure your tyres remain in good condition and pass the MOT.
Bodywork and Structural Integrity
While not as common as mechanical failures, issues with bodywork and structural integrity can also lead to MOT failures. Inspectors will look for signs of corrosion, damage, or any structural weaknesses that could affect safety.
Repair costs for bodywork can vary widely based on the extent of the damage. Keeping your vehicle clean and addressing any signs of rust early can help maintain its structural integrity.
Understanding these common issues and their associated costs can help you prepare for your BYD Sealion 7’s MOT. Regular maintenance and timely repairs can significantly reduce the risk of failure, ensuring your vehicle remains safe and roadworthy.
