2011 Chrysler-Jeep Grand Cherokee — MOT failures & pass rate
Across 289 MOT tests, the 2011 Chrysler-Jeep Grand Cherokee recorded a 79.6% pass rate. All cars of a similar age fail 23.1% of the time, so this is 2.7pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 13.2% of tests against 8.3% for the next-worst category.
At component level the recurring items are stop lamp, headlamp aim and headlamp — stop lamp alone was recorded 16 times.
Mileage matters less than usual here: the 2011 Grand Cherokee fails 18.6% of the time in the 60-90k band and 14.7% at 120-150k, a spread of only 3.9 points.
Brakes is the most common advisory, noted on 25.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.3% in 2021 to 19.6% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2011 Grand Cherokee
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 13.2% of tests. Start there.
- Lighting & signalling (13.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.3% 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.
- Suspension (4.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
