2010 Chrysler 300 — MOT failures & pass rate
The 2010 Chrysler 300 passed 73.2% of its 932 recorded MOT tests. That is 2.5 percentage points worse than all cars of a similar age, which fail at 24.3%. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
One area stands out: brakes, recorded in 18.2% of tests against 10.7% for the next-worst category.
At component level the recurring items are rbt (sp), pins and bushes and position lamp — rbt (sp) alone was recorded 111 times.
Mileage is the strongest signal on the record: 13.0% of 0-30k cars fail, rising to 30.5% once past 150k — 2.3× the risk.
Brakes is the most common advisory, noted on 35.7% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 29.9% in 2021 to 22.1% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 35.7% | 333 |
| 2 | Suspension | 31.8% | 296 |

| 5 | Other defects | 8.9% | 83 |
| 6 | Lighting & signalling | 8.1% | 75 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 46 | 13.0% |
| 30-60k | 105 | 24.8% |
| 60-90k | 218 | 26.6% |
| 90-120k | 242 | 28.1% |
| 120-150k | 154 | 26.6% |
| 150k+ | 167 | 30.5% |

What to check before buying a 2010 300
The failure pattern for this year is specific enough to inspect against: brakes accounted for 18.2% of tests. Start there.
- Brakes (18.2% 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 (10.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.2% 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.
