2019 Jeep Wrangler — MOT failures & pass rate
The 2019 Jeep Wrangler passed 92.0% of its 2,831 recorded MOT tests. Against large SUVs of a similar age (9.7% fail rate), the 2019 Wrangler comes out 1.7pp better. Failures cluster in lighting & signalling, visibility and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (3.7%) and visibility (2.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, wipers and joints — headlamp aim alone was recorded 68 times.
A 90-120k example is materially riskier than a 0-30k one: 16.4% versus 4.9%.
Fuel type barely separates them — diesel fails 7.9% of the time against 8.0% for petrol.
Brakes is the most common advisory, noted on 9.2% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 19.6% in 2021 to 9.7% in 2025, as the worst-kept examples leave the fleet.

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

| 5 | Visibility | 4.1% | 116 |
| 6 | Emissions & environmental | 2.8% | 79 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 0-30k | 1,542 | 4.9% |
| 30-60k | 999 | 9.8% |
| 60-90k | 203 | 17.7% |
| 90-120k | 61 | 16.4% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |

What to check before buying a 2019 Wrangler
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 3.7% of tests. Start there.
- Lighting & signalling (3.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.4% 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.
- Body, structure & corrosion (1.6% 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.
