2007 Chrysler-Jeep 300 — MOT failures & pass rate
The 2007 Chrysler-Jeep 300 passed 74.9% of its 7,628 recorded MOT tests. All cars of a similar age fail 26.8% of the time, so this is 1.7pp better than the group it competes with. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
Brakes dominates the failure mix at 17.2% of all tests — 5.9 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 830 times.
Mileage is the strongest signal on the record: 14.8% of 0-30k cars fail, rising to 26.3% once past 150k.
Split by fuel, diesel examples fail 2.4pp more often than petrol ones (25.4% vs 23.0%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 35.3% of tests without failing them.
The trend is improving — the fail rate fell from 26.4% in 2021 to 24.5% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2007 300
On a 2007 300, brakes is what the MOT record says goes wrong most — it appeared in 17.2% of tests. Check these areas before you commit.
- Brakes (17.2% 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 (11.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.6% 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.
