Mercedes-Benz EQC MOT failure rates: what to expect

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

Updated 4th September 2026 DVSA data: Across 12,040 recorded MOT tests, 14.8% failed.

The Mercedes-Benz EQC is a premium electric SUV that generally performs well in MOT tests. The most common problems include issues with lights, brakes, and suspension components, with typical repair costs varying based on the specific fault.

Lights and Electrical Systems

One of the most frequent causes of MOT failures for the Mercedes-Benz EQC is related to lights and electrical systems. This can include faulty headlights, brake lights, or indicators. These issues often arise from blown bulbs, corroded connections, or malfunctioning sensors.

Regular checks of the lighting system can help prevent these issues from arising.

Brake System Failures

Brakes are critical for safety, and any issues in this area can lead to an MOT failure. Common problems with the EQC’s braking system include worn brake pads, damaged discs, or issues with the brake fluid. The DVSA MOT data indicates that brake-related failures are among the top reasons for MOT rejections.

Regular maintenance and timely replacement of brake components can help ensure optimal performance and safety.

Suspension and Steering Issues

Suspension and steering components are essential for vehicle handling and comfort. The EQC can experience wear in parts such as shock absorbers, springs, and bushings, leading to MOT failures. Symptoms of suspension issues may include unusual noises or a rough ride.

Repair costs for suspension components can vary widely. Regular inspections can help identify problems before they lead to an MOT failure.

Tyres and Wheel Alignment

Tyres are a crucial aspect of vehicle safety and performance. An MOT failure can occur if the EQC has tyres that are worn beyond the legal limit or if they are improperly inflated. Additionally, issues with wheel alignment can lead to uneven tyre wear and affect handling.

Regular checks on tyre tread depth and pressure can help maintain safety and performance, reducing the likelihood of MOT failures.

Exhaust and Emissions Systems

Although the EQC is an electric vehicle and does not have a traditional exhaust system, it still has components related to emissions that can affect its MOT status. Issues with the battery management system or electric motor can lead to performance problems that may trigger a failure.

Keeping software updated and monitoring the vehicle’s performance can help prevent these costly repairs.

Bodywork and Structural Integrity

Finally, bodywork and structural integrity are also assessed during an MOT. Common issues may include rust, corrosion, or damage to the chassis. While the EQC is built with quality materials, wear and tear can still occur, especially if the vehicle has been exposed to harsh conditions.

Regular cleaning and protective treatments can help maintain the vehicle’s exterior and prevent corrosion, ultimately aiding in passing the MOT.

Maintaining the Mercedes-Benz EQC with regular checks and servicing can significantly reduce the risk of MOT failures and associated repair costs.
