Renault Symbioz MOT failure rates: what to expect

What fails on a Renault Symbioz at MOT, how often, and what each fix typically costs.

Updated 4th September 2026

The Renault Symbioz often faces MOT failures due to issues with its brakes, suspension, and electrical systems. Common problems include worn brake pads, faulty shock absorbers, and battery-related faults. Fixing these issues can vary in cost, but addressing them promptly can help ensure your vehicle passes its MOT.

Brake System Failures

One of the most frequent reasons for MOT failures in the Renault Symbioz is related to the braking system. Worn brake pads and discs are common culprits. If the brake pads are below the legal limit, they must be replaced to pass the MOT.

Regular maintenance and checks can help prevent these issues from becoming serious.

Suspension Problems

The suspension system is crucial for vehicle stability and comfort. MOT failures often arise from worn shock absorbers or damaged springs. If the shock absorbers leak or are excessively worn, they will fail the MOT.

Regular inspections of the suspension components can help identify issues early, potentially saving you money in the long run.

Electrical System Faults

Electrical issues can also lead to MOT failures in the Renault Symbioz. Common problems include malfunctioning lights, battery issues, or faults in the vehicle’s electronic control systems. These issues can often be diagnosed with a simple scan of the vehicle’s onboard computer.

Regular checks of the vehicle’s lights and battery can help avoid unexpected failures during the MOT.

Tyre Condition and Tread Depth

Tyres are another critical area where the Renault Symbioz can fail its MOT. Insufficient tread depth or damage to the sidewalls can lead to an automatic failure. The legal minimum tread depth in the UK is 1.6mm across the central three-quarters of the tyre.

Regularly checking tyre pressure and tread depth can help ensure your tyres remain roadworthy and compliant with MOT standards.

Exhaust Emissions and Noise

Exhaust emissions are closely monitored during the MOT, and any issues can lead to failure. The Renault Symbioz may experience problems with the catalytic converter or exhaust system, which can cause excessive emissions or noise.

Regular servicing of the exhaust system can help identify issues early, ensuring your vehicle remains compliant with emissions regulations.

Bodywork and Structural Integrity

While not as common, bodywork and structural integrity can also be points of failure during an MOT. Rust or corrosion on critical components can lead to a failure. The Renault Symbioz, being a modern vehicle, is less prone to these issues, but it is still essential to keep an eye on the bodywork.

Regular cleaning and maintenance can help prevent rust and keep the vehicle in good condition.

By staying on top of these common issues and addressing them promptly, you can help ensure that your Renault Symbioz passes its MOT without significant costs or complications. Regular maintenance and checks are key to keeping your vehicle in optimal condition.
