2010 Chrysler-Jeep 300 — MOT failures & pass rate
2,390 MOT tests on the 2010 Chrysler-Jeep 300 are in this dataset, and 75.6% of them passed. All cars of a similar age fail at 24.3%, so the 2010 300 sits squarely on the average. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
Brakes dominates the failure mix at 15.7% of all tests — 4.1 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are rbt (sp), position lamp and track rod end — rbt (sp) alone was recorded 247 times.
Condition tracks the odometer closely. Failures run at 13.9% in the 0-30k band and 23.5% in the 150k+ band, a 9.7-point spread.
Advisories point at the next bill rather than this one: suspension was flagged on 33.9% of tests without failing them.

What to check before buying a 2010 300
On a 2010 300, brakes is what the MOT record says goes wrong most — it appeared in 15.7% of tests. Check these areas before you commit.
- Brakes (15.7% 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.
- Lighting & signalling (11.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.1% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
