2001 Chrysler-Jeep Grand Cherokee — MOT failures & pass rate
565 MOT tests on the 2001 Chrysler-Jeep Grand Cherokee are in this dataset, and 75.6% of them passed. All cars of a similar age fail 27.2% of the time, so this is 2.7pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (13.8%) and brakes (12.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are joints, headlamp and headlamp aim — joints alone was recorded 43 times.
Mileage matters less than usual here: the 2001 Grand Cherokee fails 26.2% of the time in the 30-60k band and 28.7% at 150k+, a spread of only 2.5 points.
Advisories point at the next bill rather than this one: suspension was flagged on 43.0% of tests without failing them.
The trend is improving — the fail rate fell from 23.9% in 2021 to 22.4% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2001 Grand Cherokee
On a 2001 Grand Cherokee, lighting & signalling is what the MOT record says goes wrong most — it appeared in 13.8% of tests. Check these areas before you commit.
- Lighting & signalling (13.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (12.9% 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.
- Body, structure & corrosion (9.7% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
