What to check before buying a used Tesla

Every used Tesla deserves a thorough inspection, but knowing the common weak points for your target model gives you a serious advantage. Since body & rust faults are the most common across the range, pay particular attention to this area during any viewing or test drive.

The 2 dangerous-rated faults deserve special attention. These include Phantom braking and autopilot issues, Power steering system failure (GEN1). Any of these can compromise safety or result in repair bills running well into the thousands.

A complete dealer service history is one of the strongest indicators of how well a Tesla has been looked after. Many of the faults on this page are preventable or can be caught early through regular servicing. If the seller cannot produce service records, treat that as a significant red flag.

Check the MOT history carefully too. With a 13.8% average failure rate across the Tesla range, some advisories and minor failures are normal over the life of any car. What matters is the pattern: recurring failures in the same area suggest an underlying problem, while a history of clean passes is encouraging.

Tesla repair costs: what to expect

Across all documented faults, the average Tesla repair costs between £256 and £486 at an independent garage. At the top end, the most expensive single repair can reach £1,500 or more. Main dealer rates are typically 30% to 50% higher across the board.

The single most expensive Tesla repair in our database is Drive Unit Failure, which can cost £8,000–£12,000 at a main dealer.

These figures are based on reported UK repair costs and serve as a guide. Actual prices will vary depending on your location, the garage, and the parts required. Getting quotes from two or three specialists before committing to any major work is always worthwhile.
