2013 Jeep Grand Cherokee — MOT failures & pass rate
Across 4,081 MOT tests, the 2013 Jeep Grand Cherokee recorded an 83.5% pass rate. Large SUVs of a similar age fail at 16.4%, so the 2013 Grand Cherokee sits squarely on the average. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (8.1%) and brakes (6.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp, washers and tread depth — headlamp alone was recorded 135 times.
Condition tracks the odometer closely. Failures run at 7.3% in the 0-30k band and 23.6% in the 150k+ band, a 16.3-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 21.3% of tests without failing them.
The trend is worsening — 14.0% of tests failed in 2021 against 17.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2013 Grand Cherokee
On a 2013 Grand Cherokee, lighting & signalling is what the MOT record says goes wrong most — it appeared in 8.1% of tests. Check these areas before you commit.
- Lighting & signalling (8.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (6.5% 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.
- Tyres (4.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
