2009 Chrysler-Jeep 300 — MOT failures & pass rate
Across 2,499 MOT tests, the 2009 Chrysler-Jeep 300 recorded a 74.1% pass rate. All cars of a similar age fail at 25.3%, so the 2009 300 sits squarely on the average. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
Brakes dominates the failure mix at 17.5% of all tests — 6.0 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are rbt (sp), pins and bushes and position lamp — rbt (sp) alone was recorded 305 times.
Mileage is the strongest signal on the record: 17.9% of 0-30k cars fail, rising to 27.7% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 34.0% of tests without failing them.
The trend is improving — the fail rate fell from 26.7% in 2021 to 25.1% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2009 300
On a 2009 300, brakes is what the MOT record says goes wrong most — it appeared in 17.5% of tests. Check these areas before you commit.
- Brakes (17.5% 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 (11.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.4% 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.
