Across 2,196 MOT tests, the 2012 Jeep Grand Cherokee Overland Crd A recorded an 84.4% pass rate. That is 6.0 percentage points better than all cars of a similar age, which fail at 21.6%. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 10.1% of tests against 5.7% for the next-worst category.
At component level the recurring items are headlamp aim, stop lamp and headlamp — headlamp aim alone was recorded 75 times.
Condition tracks the odometer closely. Failures run at 4.8% in the 0-30k band and 17.1% in the 150k+ band, a 12.3-point spread — more than double.
Brakes is the most common advisory, noted on 19.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 14.3% of tests failed in 2021 against 16.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2012 Grand Cherokee Overland Crd A
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 10.1% of tests. Start there.
- Lighting & signalling (10.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.7% 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.
- Tyres (3.7% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
