2007 Chrysler 300 C — MOT failures & pass rate
1,659 MOT tests on the 2007 Chrysler 300 C are in this dataset, and 74.6% of them passed. That is 1.5 percentage points better than all cars of a similar age, which fail at 26.9%. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
One area stands out: brakes, recorded in 18.3% of tests against 12.8% 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 199 times.
Mileage is the strongest signal on the record: 9.1% of 0-30k cars fail, rising to 28.4% once past 150k — 3.1× the risk.
Brakes is the most common advisory, noted on 31.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 27.5% in 2021 to 24.4% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2007 300 C
The failure pattern for this year is specific enough to inspect against: brakes accounted for 18.3% of tests. Start there.
- Brakes (18.3% 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 (12.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.1% 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.
