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

The Aston Martin Vantage is a luxury sports car that often faces specific issues during its MOT tests. Common failures include problems with the suspension, brakes, and emissions systems. Addressing these issues can vary in cost, but being aware of them can help owners maintain their vehicles effectively.
Suspension Issues
One of the most frequent causes of MOT failure for the Aston Martin Vantage is suspension-related problems. This can include worn shock absorbers or damaged bushings. If the suspension components are not functioning correctly, it can affect the vehicle’s handling and safety.
Replacing shock absorbers typically costs between £300 and £600, depending on whether you opt for OEM or aftermarket parts. Bushings can also be replaced for around £100 to £200. Regular inspections can help catch these issues early, potentially saving on more extensive repairs down the line.
Brake System Failures
The brake system is another critical area where the Aston Martin Vantage may encounter MOT failures. Common issues include worn brake pads, corroded brake discs, or leaks in the brake lines. A malfunctioning brake system not only fails the MOT but also poses significant safety risks.
Replacing brake pads usually costs between £150 and £300, while brake discs can range from £200 to £500. If there are leaks in the brake lines, repairs can be more complex and expensive, often costing upwards of £200. Regular maintenance and timely replacements can help ensure the braking system remains in good condition.
Emissions System Problems
Emissions failures are increasingly common in modern vehicles, including the Aston Martin Vantage. Factors such as a faulty catalytic converter or issues with the exhaust system can lead to excessive emissions, resulting in an MOT failure.
A new catalytic converter can be quite costly, typically ranging from £500 to £1,500, depending on the model year and specifications. Exhaust system repairs may vary in cost, from £100 for minor fixes to over £1,000 for complete replacements. Keeping the emissions system well-maintained can help avoid these expensive repairs.
Tyre Condition
Tyres are a crucial aspect of vehicle safety and are frequently checked during the MOT. The Aston Martin Vantage requires tyres that meet specific tread depth and condition standards. Worn or damaged tyres can lead to an automatic failure.
Replacing tyres can vary significantly in cost, depending on the brand and specifications. On average, a new tyre for a Vantage can cost between £150 and £300. Regularly checking tyre pressure and tread depth can help prevent MOT failures and ensure optimal performance.
Lights and Electrical Systems
Another common area of failure during the MOT for the Aston Martin Vantage is the lighting and electrical systems. Issues such as blown bulbs, faulty wiring, or malfunctioning electronic components can lead to a failed test.
Replacing bulbs is generally inexpensive, usually costing around £10 to £30. However, if there are more significant electrical issues, such as wiring faults, repairs can escalate to £100 or more. Regular checks of all lights and electrical systems can help maintain compliance with MOT standards.
Bodywork and Structural Integrity
While less common, bodywork and structural integrity can also lead to MOT failures for the Aston Martin Vantage. Rust, corrosion, or damage to the chassis can be serious issues that need addressing.
Repairing bodywork can vary widely in cost, depending on the extent of the damage. Minor repairs may cost around £200, while more extensive structural repairs can run into the thousands. Regular inspections can help identify potential issues before they become significant problems.
Maintaining the Aston Martin Vantage requires attention to detail, especially when it comes to the areas that frequently cause MOT failures. By being proactive and addressing these common issues, owners can ensure their vehicles remain roadworthy and retain their value.
