Chrysler-Jeep Patriot MOT pass rate & common failures
The Chrysler-Jeep Patriot appears in 4,957 MOT tests spanning model years 2007–2015, and 67.5% of them passed. All cars of a similar age fail 25.2% of the time, so this is 7.3pp worse than the group it competes with. Its most common failure areas are suspension, lighting & signalling and brakes.
What the MOT record shows
One area stands out: suspension, recorded in 22.1% of tests against 17.0% for the next-worst category.
At component level the recurring items are pins and bushes, ball joint and position lamp — pins and bushes alone was recorded 752 times.
Mileage matters less than usual here: the Patriot fails 28.7% of the time in the 30-60k band and 31.3% at 150k+, a spread of only 2.7 points.
Fuel type barely separates them — diesel fails 32.4% of the time against 32.7% for petrol.
Suspension is the most common advisory, noted on 45.9% of tests — work that passed today but is likely due soon.

What to check before buying a Chrysler-Jeep Patriot
- Suspension (22.1% 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 (17.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.7% 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.
