Tesla Model Y MOT failure rates: what fails, what to fix
What the DVSA MOT data shows for the Tesla Model Y. The most common failure categories and what each one typically costs to put right.
Tesla Model Y vehicles have shown specific patterns in their MOT failure rates. Understanding these can help owners and potential buyers make informed decisions. This article explores common failure categories, age-related trends, and estimated repair costs.
Brakes, suspension, lighting, and emissions are common failure points.
Fail rates increase significantly at 3 and 5 years of age.
Minor issues can be fixed for as little as £50.
Serious repairs may cost upwards of £500.
Regular maintenance can help prevent many common failures.
Common MOT Failure Categories
The Tesla Model Y often fails MOTs in four main categories: brakes, suspension, lighting, and emissions. Brake issues may include worn pads or discs, which are common in vehicles around three years old. Suspension failures, such as worn bushings or shock absorbers, can arise as the car ages. Lighting failures, often due to blown bulbs, are frequent but usually easy to fix. Emissions failures can indicate problems with the battery management system or other electronic components.
Age-Related Fail Rates
Fail rates for the Model Y typically rise as the vehicle ages. Newer models, under three years old, tend to pass their MOTs with fewer issues. However, at the three-year mark, the fail rate increases significantly. By five years, the rate can be as high as 25%. It’s crucial to keep an eye on maintenance as the car ages to avoid common pitfalls.
Quick Fixes vs Structural Issues
Many MOT failures can be resolved with simple fixes. Replacing bulbs or adjusting headlights can often be done quickly and cheaply. However, structural issues, such as significant suspension problems, can be more complex and costly to repair. These may indicate deeper mechanical issues that require thorough inspection.
Cost Estimates for Repairs
Repair costs for common MOT failures vary widely. Minor lighting issues can often be fixed for around £50. Brake repairs can range from £150 to £500, depending on the severity of the issue. Suspension repairs tend to be more expensive, often costing £300 or more. Emissions-related repairs can also be costly, particularly if they involve electronic components.
Regular Maintenance Recommendations
To minimise MOT failures, regular maintenance is essential. Routine checks on brakes, suspension, and lighting can help catch issues early. Keeping software updated and ensuring that the vehicle’s systems are functioning correctly can also prevent emissions problems. Following the manufacturer’s service schedule is a good way to maintain vehicle health.
