Top three failure systems, annotated from 1,216 failed first-time tests. Arrows point to where the defect is found on the car.
Tyres are 57% of everything that fails a Jaguar I-Pace
18,063 inspections in a single year make the I-PACE one of the better-documented electric car. Tyres cause 57.3% of its failures; steering take 3.3× the share they take on petrol and diesel cars of the same age.
The three-year vs six-year picture
I-PACE failure rate. Petrol cars of the same age fail 8.2%.
I-PACE failure rate, against 12.9% for petrol.
At three years old the Jaguar I-Pace fails 6.4% of the time, under the 8.2% of a petrol car the same age. By 6 years that reaches 10.4%. Tyres cause 57.3% of its failures.
Play at the straight-ahead
Steering take 10.3% of the defects that fail this car, 3.3× the share seen on petrol and diesel cars of the same age. The most common item in that group is "A steering ball joint with excessive wear or free play", recorded 165 times in 2024.
Where it concentrates
The I-PACE stays under the petrol fleet at every age we can measure. What it does fail on is unusually concentrated.
What to check
Check tyre age and tread across the full width, inner edge included. Electric cars wear tyres faster; a cheap mismatched set on a used car tells you how it was run. Trivial to fix, but a car advertised with worn wipers and a fresh failure certificate tells you how it was maintained. Ask for the full MOT history by registration on the free DVSA service: advisories are next year's failures.

- 18,063 inspections in 2024 make this one of the best-documented electric cars in the data.
- Steering take 3.3× the share of failures they take on petrol and diesel cars of the same age.
- Failure rate rises from 5.6% at 4 years to 10.4% at 6: a gentle ageing curve.
No battery health, no motor, no charging performance. The test covers brakes, suspension, steering, tyres, lights, visibility and structure. A car with a badly degraded battery passes as long as it stops and steers. Read this page as evidence about the chassis, not the powertrain. Cars are tested from their third year, so the newest model years are missing; every figure carries its sample size for that reason. Full methodology.
