2013 Chrysler 300 — MOT failures & pass rate
The 2013 Chrysler 300 passed 80.2% of its 526 recorded MOT tests. All cars of a similar age fail at 20.1%, so the 2013 300 sits squarely on the average. Failures cluster in brakes, lighting & signalling and steering.
What the MOT record shows
Brakes dominates the failure mix at 12.2% of all tests — 7.2 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are rbt (sp), track rod end and service brake performance — rbt (sp) alone was recorded 41 times.
Mileage is the strongest signal on the record: 10.7% of 0-30k cars fail, rising to 16.3% once past 120-150k.
Advisories point at the next bill rather than this one: brakes was flagged on 22.4% of tests without failing them.
The trend is worsening — 17.1% of tests failed in 2021 against 23.6% in 2025, the usual pattern as a fleet ages.

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 | 22.4% | 118 |
| 2 | Tyres | 18.4% | 97 |
| 3 | Suspension | 13.1% | 69 |

| 5 | Other defects | 4.6% | 24 |
| 6 | Visibility | 4.2% | 22 |
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 | 56 | 10.7% |
| 30-60k | 139 | 19.4% |
| 60-90k | 165 | 21.8% |
| 90-120k | 95 | 25.3% |
| 120-150k | 43 | 16.3% |

What to check before buying a 2013 300
On a 2013 300, brakes is what the MOT record says goes wrong most — it appeared in 12.2% of tests. Check these areas before you commit.
- Brakes (12.2% 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 (4.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Steering (4.4% of tests): Play, leaks or worn track rod ends — affects handling and is a safety item. Typical repair: £150–£500.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
