Mercedes-Benz EQA MOT failure rates: what to expect

What fails on a Mercedes-Benz EQA at MOT, how often, and what each fix typically costs.

Updated 4th September 2026 DVSA data: Across 9,511 recorded MOT tests, 8.9% failed.

The Mercedes-Benz EQA is generally a reliable electric vehicle, but like any car, it can encounter issues that lead to MOT failures. Common problems include issues with lights, brakes, and suspension components. Addressing these failures can vary in cost, so understanding the most frequent issues can help owners prepare for their MOT.

Lights and Electrical Systems

One of the most common reasons for MOT failure in the Mercedes-Benz EQA is related to lights and electrical systems. This includes issues such as blown bulbs, malfunctioning indicators, or problems with the vehicle’s wiring.

Regular checks of all lights before the MOT can help avoid these common failures.

Braking System

The braking system is crucial for safety and is a key area of focus during the MOT. Common failures in the EQA may include worn brake pads, damaged discs, or issues with the brake fluid.

Ensuring that the braking system is regularly inspected can help maintain performance and safety.

Suspension Components

Issues with the suspension system can lead to MOT failures, particularly if components such as shock absorbers or springs are damaged. The EQA’s suspension is designed for comfort and performance, but wear and tear can affect its effectiveness.

Regular maintenance checks can help identify these issues before they lead to an MOT failure.

Tyres and Wheel Alignment

Tyres are another common area where the EQA may fail its MOT. Issues can include insufficient tread depth, uneven wear, or damage to the sidewalls. The legal minimum tread depth in the UK is 1.6mm, but it is advisable to replace tyres once they reach 3mm for better safety.

Additionally, if wheel alignment is off, it can lead to uneven tyre wear and affect handling. Regular checks of tyre condition and pressure can help prevent MOT failures.

Exhaust and Emissions

While the EQA is an electric vehicle and does not have a traditional exhaust system, it is still subject to checks for emissions-related components. Issues may arise with the vehicle’s battery management system or other electronic components that could affect performance.

Keeping the software updated and ensuring the vehicle is serviced regularly can help mitigate these risks.

Bodywork and Structural Integrity

Lastly, the bodywork and structural integrity of the EQA can also lead to MOT failures. Common issues include rust, damage to the chassis, or problems with doors and windows.

Regular inspections and prompt repairs can help maintain the vehicle’s integrity and avoid costly MOT failures.

By being aware of these common issues and their associated costs, Mercedes-Benz EQA owners can better prepare for their MOT and ensure their vehicle remains in good condition. Regular maintenance and timely repairs are key to keeping the EQA running smoothly and safely.
