2010 Chrysler-Jeep Grand Cherokee — MOT failures & pass rate
939 MOT tests on the 2010 Chrysler-Jeep Grand Cherokee are in this dataset, and 80.1% of them passed. That is 4.3 percentage points better than all cars of a similar age, which fail at 24.2%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.5% of all tests — 6.1 points clear of suspension, so it is the first thing to check.
At component level the recurring items are ball joint, position lamp and headlamp aim — ball joint alone was recorded 78 times.
A 150k+ example is materially riskier than a 30-60k one: 27.6% versus 10.8%.
Advisories point at the next bill rather than this one: suspension was flagged on 38.0% of tests without failing them.

What to check before buying a 2010 Grand Cherokee
On a 2010 Grand Cherokee, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.5% of tests. Check these areas before you commit.
- Lighting & signalling (14.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.4% 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 (6.2% 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.
