2013 Chrysler 300 C — MOT failures & pass rate
Across 343 MOT tests, the 2013 Chrysler 300 C recorded an 84.3% pass rate. All cars of a similar age fail 19.9% of the time, so this is 4.1pp better than the group it competes with. Failures cluster in brakes, tyres and suspension.
What the MOT record shows
No single area dominates — brakes (7.9%) and tyres (5.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), headlamp aim and service brake performance — rbt (sp) alone was recorded 19 times.
Mileage is the strongest signal on the record: 10.1% of 30-60k cars fail, rising to 22.2% once past 150k — 2.2× the risk.
Advisories point at the next bill rather than this one: brakes was flagged on 21.6% of tests without failing them.
The trend is improving — the fail rate fell from 21.4% in 2021 to 18.5% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2013 300 C
On a 2013 300 C, brakes is what the MOT record says goes wrong most — it appeared in 7.9% of tests. Check these areas before you commit.
- Brakes (7.9% 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.
- Tyres (5.3% 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.
- Suspension (3.8% 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.
