2010 Chrysler 300 C — MOT failures & pass rate
Across 471 MOT tests, the 2010 Chrysler 300 C recorded a 75.0% pass rate. That is effectively the same as all cars of a similar age (24.4% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
One area stands out: brakes, recorded in 16.4% of tests against 10.0% for the next-worst category.
At component level the recurring items are rbt (sp), position lamp and pins and bushes — rbt (sp) alone was recorded 53 times.
Mileage matters less than usual here: the 2010 300 C fails 25.4% of the time in the 30-60k band and 23.4% at 150k+, a spread of only 2.0 points.
Suspension is the most common advisory, noted on 31.6% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 29.0% in 2021 to 25.6% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2010 300 C
The failure pattern for this year is specific enough to inspect against: brakes accounted for 16.4% of tests. Start there.
- Brakes (16.4% 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 (10.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
