Genesis G90 MOT failure rates: what to expect

What fails on a Genesis G90 at MOT, how often, and what each fix typically costs.

The Genesis G90 is a luxury saloon that combines style with performance. However, like any vehicle, it can encounter issues during its MOT. Common failures include problems with lights, brakes, and suspension components. Repair costs can vary, but understanding these issues can help you prepare for your MOT.

Common Light Failures

One of the most frequent reasons for MOT failures in the Genesis G90 is faulty lights. This includes issues with headlights, brake lights, and indicators. A blown bulb is often the culprit, which is a simple fix but can lead to a failed MOT if not addressed.

Replacing a bulb typically costs between £10 and £30, depending on the type and whether you do it yourself or have a garage handle it. However, if the problem lies with the wiring or the light unit itself, repairs can escalate to £100 or more. Regularly checking your lights can help avoid these issues.

Brake System Deficiencies

The braking system is crucial for safety, and any deficiencies can lead to an MOT failure. Common issues include worn brake pads, damaged discs, or leaks in the brake lines. The Genesis G90, being a heavier vehicle, can experience more wear on its brakes.

Replacing brake pads can cost between £100 and £250, while brake discs may range from £150 to £300. If there are leaks in the brake lines, repairs can be more extensive, potentially costing upwards of £200. Ensuring your brakes are regularly checked can prevent these costly repairs.

Suspension Problems

Suspension issues are another common failure point for the Genesis G90 during an MOT. Problems can arise from worn shock absorbers, damaged springs, or issues with the steering components. These problems can affect the vehicle’s handling and comfort.

Replacing shock absorbers can cost between £150 and £300 per pair, while springs may range from £100 to £200. If steering components need replacement, costs can vary widely based on the specific parts required. Regular maintenance checks can help identify these issues before the MOT.

Tyre Condition and Tread Depth

Tyres are critical for safety and performance, and their condition is a significant factor in MOT assessments. The minimum legal tread depth in the UK is 1.6mm, but it is advisable to replace tyres once the tread reaches 3mm for optimal performance.

Tyre replacement costs can vary, with prices typically ranging from £50 to £150 per tyre, depending on the brand and size. Additionally, if your tyres are unevenly worn, it may indicate alignment issues, which can cost around £50 to £100 to fix. Regularly checking tyre pressure and tread depth can help maintain safety and avoid MOT failures.

Emissions and Exhaust System

The emissions test is a critical part of the MOT, and any issues with the exhaust system can lead to a failure. Common problems include leaks, a failing catalytic converter, or issues with the oxygen sensors. The Genesis G90 is designed to meet strict emissions standards, so any failure in this area can be concerning.

Repairing or replacing a catalytic converter can be expensive, typically costing between £500 and £1,500. If there are minor leaks or issues with exhaust pipes, repairs may range from £100 to £300. Regular servicing can help ensure your emissions system remains in good condition.

Battery and Electrical Components

Electrical issues can also lead to MOT failures, particularly with the battery and associated components. Problems such as a failing battery, corroded terminals, or issues with the alternator can affect the vehicle’s performance and safety.

Replacing a battery can cost between £100 and £200, while alternator repairs may range from £200 to £500. Regular checks of the electrical system can help prevent unexpected failures during the MOT process. Keeping connections clean and ensuring the battery is in good condition can save you time and money.

Understanding the common issues that can lead to an MOT failure in the Genesis G90 can help you prepare and maintain your vehicle effectively. Regular checks and maintenance can not only enhance safety but also save you from costly repairs down the line.
