Jaguar Xjr MOT Reliability Overview
The Jaguar Xjr is a relatively common sight on UK roads, with 47,161 MOT test results recorded in our database spanning 28 manufacture years. It has an overall MOT pass rate of 70.1% and a failure rate of 29.9%, which is above the UK average of approximately 37%.
Based on this data, the Jaguar Xjr earns a "Very Good" reliability rating. The average Jaguar Xjr presents for MOT with approximately 94,407 miles on the clock. Manufacture year matters: 2017 models achieve the highest pass rate at 92.4%, while 1990 models have the lowest at 62.2%. This 30.2 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Jaguar Xjr is Suspension, affecting 32.9% of all tests. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. The second most common issue is Brakes at 26.2%. Tyres rounds out the top three at 16.1%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Jaguar Xjr shows a moderate increase in MOT failures after warranty. The 23% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 14 (35.1% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Jaguar Xjr MOT Data
The Jaguar Xjr is a relatively common sight on UK roads, with 47,161 MOT test results recorded in our database spanning 28 manufacture years. It has an overall MOT pass rate of 70.1% and a failure rate of 29.9%, which is above the UK average of approximately 37%.
For Jaguar Xjr owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on suspension and brakes for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Xjr is likely to perform.
Suspension — 32.9% of failures
Suspension issues account for 32.9% of MOT failures on the Jaguar Xjr. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Brakes — 26.2% of failures
Brakes issues account for 26.2% of MOT failures on the Jaguar Xjr. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Tyres — 16.1% of failures
Tyres issues account for 16.1% of MOT failures on the Jaguar Xjr. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
