2011 Chrysler-Jeep Patriot — MOT failures & pass rate
Across 414 MOT tests, the 2011 Chrysler-Jeep Patriot recorded a 72.2% pass rate. That is 4.9 percentage points worse than all cars of a similar age, which fail at 22.9%. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
One area stands out: suspension, recorded in 19.8% of tests against 12.6% for the next-worst category.
At component level the recurring items are ball joint, pins and bushes and position lamp — ball joint alone was recorded 55 times.
Mileage matters less than usual here: the 2011 Patriot fails 27.9% of the time in the 30-60k band and 24.5% at 120-150k, a spread of only 3.4 points.
Suspension is the most common advisory, noted on 37.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 25.3% of tests failed in 2021 against 28.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2011 Patriot
The failure pattern for this year is specific enough to inspect against: suspension accounted for 19.8% of tests. Start there.
- Suspension (19.8% 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.
- Lighting & signalling (12.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
