FIGURE 1 // WHERE IT WEARSVauxhall Mokka
Top three failure systems, annotated from 226 failed first-time tests. Arrows point to where the defect is found on the car.
The Vauxhall Mokka beats the petrol fleet at every age we can measure
2,837 inspections in a single year make the MOKKA a modestly documented electric car in the data. Tyres cause 34.7% of its failures; suspension take 2.0× the share they take on petrol and diesel cars of the same age.

First-time failure rate
AT 3 YEARS OLD8.0%
Overall first-time failure rate.
AT FLEET YEARS OLD12.0%
All electric cars in the data.
At three years old the Vauxhall Mokka fails 8.1% of the time, under the 8.2% of a petrol car the same age. Tyres cause 34.7% of its failures.
FIGURE 2 // SUSPENSION ARM AND BUSH53 certificates in 2024
The joint that wears out first
Suspension take 27.1% of the defects that fail this car, 2.0× the share seen on petrol and diesel cars of the same age. The most common item in that group is "A suspension pin, bush or joint excessively worn", recorded 53 times in 2024.
SECTION // SUSPENSION CONCENTRATION
Where it concentrates
The MOKKA 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. Have the suspension joints, bushes and springs checked on a lift. On this car it is a leading cause of failure and it is not visible from the outside. 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.
3 inspection points:
✓ Tyre inner-edge wear and age
✓ Suspension joints and bushes on a lift
✓ Wipers and washers

OTHER VAUXHALL ELECTRIC CARS
Three things the data shows
- 2,837 inspections in 2024 make this one of the adequately-documented electric cars in the data.
- Suspension take 2.0× the share of failures they take on petrol and diesel cars of the same age.
- It ranks 25 of 83 electric cars by first-time failure rate.
LIMITS // WHAT THE INSPECTION DOES NOT TELL YOU
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.
