2012 Chrysler 300 C — MOT failures & pass rate
589 MOT tests on the 2012 Chrysler 300 C are in this dataset, and 77.1% of them passed. All cars of a similar age fail 21.6% of the time, so this is 1.3pp worse than the group it competes with. Failures cluster in brakes, suspension and tyres.
What the MOT record shows
One area stands out: brakes, recorded in 11.7% of tests against 7.6% for the next-worst category.
At component level the recurring items are rbt (sp), track rod end and pins and bushes — rbt (sp) alone was recorded 44 times.
Mileage matters less than usual here: the 2012 300 C fails 20.6% of the time in the 30-60k band and 22.6% at 150k+, a spread of only 2.0 points.
Tyres is the most common advisory, noted on 20.7% of tests — work that passed today but is likely due soon.

What to check before buying a 2012 300 C
The failure pattern for this year is specific enough to inspect against: brakes accounted for 11.7% of tests. Start there.
- Brakes (11.7% 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.
- Suspension (7.6% 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.
- Tyres (6.3% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
