Jeep Grand Cherokee Crd A MOT pass rate & common failures
Across 10 model years and 1,580 tests, the Jeep Grand Cherokee Crd A passes its MOT 81.4% of the time. Against all cars of a similar age (22.4% fail rate), the Grand Cherokee Crd A comes out 3.8pp better. Its most common failure areas are lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 12.2% of all tests — 6.9 points clear of suspension, so it is the first thing to check.
At component level the recurring items are stop lamp, headlamp and headlamp aim — stop lamp alone was recorded 70 times.
Mileage is the strongest signal on the record: 13.0% of 30-60k cars fail, rising to 21.4% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 19.2% of tests without failing them.
The trend is worsening — 15.7% of tests failed in 2021 against 19.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a Jeep Grand Cherokee Crd A
- Lighting & signalling (12.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.3% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (5.2% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
