Hyundai Kona MOT failure rates: what to expect
What fails on a Hyundai Kona at MOT, how often, and what each fix typically costs.

The Hyundai Kona is generally a reliable vehicle, but like any car, it can encounter issues that lead to MOT failures. Common problems include issues with lights, brakes, and suspension components. Repair costs can vary, but understanding these common failures can help you prepare for your next MOT.
Lights and Electrical Systems
One of the most frequent causes of MOT failure for the Hyundai Kona is issues with the lights and electrical systems. This includes problems with headlights, brake lights, and indicators. A blown bulb or faulty wiring can lead to an automatic failure during the test.
Replacing a blown bulb is relatively inexpensive, typically costing around £10 to £20. However, if the issue lies with the wiring or the control unit, repairs can range from £50 to £150, depending on the complexity of the problem. Regularly checking and maintaining your lights can prevent these issues from arising.
Braking System
The braking system is crucial for safety and is closely inspected during the MOT. Common issues include worn brake pads, discs, and fluid leaks. The Hyundai Kona’s braking components can wear out over time, especially if the vehicle is frequently driven in urban areas or heavy traffic.
Replacing brake pads can cost between £100 and £200, while new brake discs may set you back an additional £150 to £300. If there are fluid leaks, the repair costs can vary significantly based on the source of the leak and the parts that need replacement. Regular brake inspections can help catch these issues before the MOT.
Suspension and Steering
Suspension and steering components are vital for vehicle handling and comfort. Common failures in the Hyundai Kona include worn shock absorbers, broken springs, and issues with the steering rack. These problems can affect the car’s stability and safety, leading to MOT failures.
Replacing shock absorbers typically costs between £150 and £300, while coil spring replacement can range from £100 to £200. Steering rack issues can be more costly, with repairs potentially exceeding £500. Regular checks and maintenance of the suspension system can help extend its lifespan and ensure a smoother ride.
Tyres and Wheel Alignment
Tyres are a critical safety feature and are thoroughly checked during the MOT. Common issues include insufficient tread depth, damage, or uneven wear. The Hyundai Kona requires tyres that meet legal standards, and failure to comply can lead to an automatic MOT failure.
Replacing tyres can cost anywhere from £50 to £150 per tyre, depending on the brand and specifications. Additionally, if the wheel alignment is off, it can cause uneven tyre wear and affect handling. A wheel alignment service typically costs around £50 to £100. Regularly checking tyre pressure and tread depth can help maintain tyre health.
Emissions and Exhaust System
The emissions system is another area where Hyundai Kona owners may face MOT failures. Common issues include a malfunctioning catalytic converter or exhaust leaks. These problems can lead to increased emissions, which is a critical aspect of the MOT test.
Replacing a catalytic converter can be quite expensive, often costing between £500 and £1,000. If there are minor exhaust leaks, repairs might be less costly, typically ranging from £100 to £300. Keeping the exhaust system in good condition is essential for passing the MOT and maintaining fuel efficiency.
General Maintenance and Pre-MOT Checks
Regular maintenance is key to preventing MOT failures. Common pre-MOT checks include inspecting lights, brakes, tyres, and the exhaust system. By addressing minor issues before the test, you can save on potential repair costs and ensure a smoother MOT experience.
Investing in a comprehensive pre-MOT inspection can cost around £50 to £100 but can save you money in the long run by identifying issues early. Keeping up with regular servicing and addressing any warning lights or unusual noises promptly can help maintain the Hyundai Kona’s reliability and performance.
