2021 Jeep Renegade 4Xe — MOT failures & pass rate
Across 724 MOT tests, the 2021 Jeep Renegade 4Xe recorded a 93.4% pass rate. All cars of a similar age fail 8.7% of the time, so this is 2.0pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.5%) and lighting & signalling (2.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and side repeaters — headlamp aim alone was recorded 19 times.
Tyres is the most common advisory, noted on 19.6% of tests — work that passed today but is likely due soon.

| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 425 | 4.0% |
| 30-60k | 277 | 9.8% |
Failure rate by age

What to check before buying a 2021 Renegade 4Xe
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.5% of tests. Start there.
- Tyres (3.5% 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.
- Lighting & signalling (2.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (0.7% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
