2014 Jeep Grand Cherokee — MOT failures & pass rate
The 2014 Jeep Grand Cherokee passed 84.1% of its 8,603 recorded MOT tests. That is effectively the same as large SUVs of a similar age (15.0% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in brakes, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — brakes (6.9%) and lighting & signalling (5.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, brake pads and rbt (sp) — tread depth alone was recorded 253 times.
Condition tracks the odometer closely. Failures run at 7.4% in the 0-30k band and 19.6% in the 150k+ band, a 12.3-point spread — more than double.
Brakes is the most common advisory, noted on 21.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 15.4% of tests failed in 2021 against 18.8% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a 2014 Grand Cherokee
The failure pattern for this year is specific enough to inspect against: brakes accounted for 6.9% of tests. Start there.
- Brakes (6.9% 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.
- Lighting & signalling (5.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.3% 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.
