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

The Nissan Ariya has gained popularity as an electric SUV, but like any vehicle, it can encounter issues that may lead to MOT failures. Common problems include electrical faults, brake issues, and suspension wear. Fixing these issues can vary in cost, but understanding them can help owners prepare for their MOT.
Electrical System Failures
Electrical system failures are among the most common reasons for MOT failures in the Nissan Ariya. Problems can arise with the battery management system, lighting, or other electronic components. If the vehicle’s warning lights are illuminated, it may indicate underlying issues that need addressing.
Fixing electrical faults can range from simple bulb replacements to more complex repairs involving the battery management system. A bulb replacement typically costs around £10 to £20, while more significant electrical repairs can run between £100 and £300, depending on the complexity of the issue.
Brake System Issues
The brake system is crucial for vehicle safety, and any faults can lead to MOT failures. Common problems with the Nissan Ariya include worn brake pads, damaged discs, or issues with the brake fluid. If the brakes are not performing adequately, they will fail the MOT.
Replacing brake pads usually costs between £100 and £200, while brake disc replacement can be more expensive, ranging from £150 to £300. Regular maintenance of the brake system can help prevent these issues and ensure the vehicle passes its MOT.
Suspension and Steering Problems
Suspension and steering issues can also lead to MOT failures for the Nissan Ariya. Common problems include worn shock absorbers, damaged springs, or issues with the steering rack. These components are vital for vehicle handling and comfort, making their proper functioning essential.
Repairing or replacing suspension components can be costly. Shock absorber replacement can cost between £150 and £300 per pair, while steering rack repairs may range from £200 to £500. Regular checks can help identify these problems early, potentially saving owners money in the long run.
Tyre Condition and Tread Depth
Tyres are a critical safety component, and their condition is a common MOT failure point. The Nissan Ariya requires tyres that meet legal tread depth requirements, which is a minimum of 1.6mm across the central three-quarters of the tyre. Worn or damaged tyres can lead to an MOT failure.
Replacing tyres can vary significantly in cost depending on the brand and size. Budget tyres may cost around £50 each, while premium brands can exceed £100. Regularly checking tyre condition and tread depth can help prevent MOT failures and ensure safe driving.
Windscreen and Wiper Issues
The windscreen and wiper system are essential for visibility, and any issues can lead to MOT failures. Common problems include cracks in the windscreen, damaged wiper blades, or malfunctioning washer systems. A windscreen with a crack larger than 40mm in the driver’s line of sight will fail the MOT.
Windscreen repairs can cost between £50 and £100, while full replacements can range from £200 to £400, depending on the vehicle’s specifications. Wiper blade replacements are relatively inexpensive, typically costing around £20 to £30. Regular maintenance of these components can help ensure clear visibility and compliance during the MOT.
Exhaust and Emissions Failures
As an electric vehicle, the Nissan Ariya has a different emissions profile than traditional petrol or diesel cars. However, issues with the exhaust system can still arise, particularly with the heat pump or other related components. Any emissions-related failures can lead to an MOT failure.
While the Ariya’s electric nature means it has no traditional exhaust system, problems with the heat pump can lead to costly repairs. Repair costs can vary widely, but owners should expect to pay between £150 and £400 for significant repairs. Regular checks can help identify potential issues before the MOT.
Understanding these common MOT failure points for the Nissan Ariya can help owners prepare for their vehicle’s annual inspection. By addressing these issues proactively, owners can ensure their vehicle remains safe and compliant, ultimately saving time and money.
