2000 Jeep Grand Cherokee — MOT failures & pass rate
The 2000 Jeep Grand Cherokee passed 72.9% of its 680 recorded MOT tests. Against large SUVs of a similar age (24.9% fail rate), the 2000 Grand Cherokee comes out 2.1pp worse. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 18.5% of all tests — 5.0 points clear of brakes, so it is the first thing to check.
At component level the recurring items are headlamp aim, joints and headlamp — headlamp aim alone was recorded 61 times.
Mileage matters less than usual here: the 2000 Grand Cherokee fails 30.8% of the time in the 30-60k band and 29.5% at 150k+, a spread of only 1.2 points.
Advisories point at the next bill rather than this one: brakes was flagged on 38.1% of tests without failing them.
The trend is improving — the fail rate fell from 30.2% in 2021 to 27.2% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2000 Grand Cherokee
On a 2000 Grand Cherokee, lighting & signalling is what the MOT record says goes wrong most — it appeared in 18.5% of tests. Check these areas before you commit.
- Lighting & signalling (18.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (13.5% 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.
- Body, structure & corrosion (11.8% 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.
