Best Jeep Models by MOT Pass Rate
Looking at overall reliability across all years, here's how Jeep's core models rank against the 71.4% national average:
| Model | Pass Rate | vs National (71.4%) | Tests | Years |
|---|---|---|---|---|
| COMPASS | 77.3% | +5.8% | 9,802 | 2007-2023 |

* Compared to overall 71.4% national average across all years. For year-adjusted comparisons that account for newer cars passing more often, see individual model breakdowns below.
Proven Durability Champions: Which Jeep Models Age Best?
These Jeep models show solid long-term reliability based on 11+ years of MOT data. Here's how they compare to the national average for cars of the same age:
High-confidence data: Only vehicles with 11+ years of MOT history and 100+ tests are included in this ranking.
| Model | Year | Fuel | vs Same-Age Average | Tested At | Pass Rate |
|---|---|---|---|---|---|
| GRAND | - | All | +12.1% | 11-14 years | 76.8% |
| GRAND | - | All | +6.7% | 18-20 years | 62.8% |
| GRAND | - | All | +5.8% | 15-17 years | 63.7% |
| G-CHEROKEE OVERLAND CRD A | - | All | +5.2% | 15-17 years | 63.0% |
| WRANGLER | - | All | +3.9% | 21+ years | 64.9% |
| WRANGLER | - | All | +2.6% | 15-17 years | 60.5% |
| WRANGLER | - | All | +1.6% | 11-14 years | 66.2% |
| CHEROKEE | - | All | +0.8% | 21+ years | 61.8% |
| GRAND | - | All | +0.2% | 21+ years | 61.2% |
How to read this: A score of "+15%" means the model passes MOTs 15 percentage points more often than the average car of the same age. These are proven results from vehicles that have genuinely aged well.
Early Performers: Strong Start, Unproven Durability
These newer Jeep models (3-6 years old) show strong early results, but haven't yet proven long-term durability:
Important caveat: Durability NOT yet proven - too early to assess long-term reliability. Older versions of the same model may tell a different story at 11+ years.
| Model | Year | Fuel | vs Same-Age Average | Tested At | Pass Rate |
|---|---|---|---|---|---|
| GRAND | - | All | +6.5% | 8-10 years | 82.0% |
| GRAND | - | All | +3.5% | 3-7 years | 88.3% |
| WRANGLER | - | All | +2.6% | 3-7 years | 87.3% |
| RENEGADE | - | All | +1.0% | 3-7 years | 85.7% |
| CHEROKEE | - | All | +0.5% | 8-10 years | 75.9% |
What this means: These models are performing well in their early years, but we recommend checking the Durability Champions section above to see how older versions of the same model family have fared over time.

About This Data
This analysis uses real MOT test results from the DVSA database, covering 70,103 tests on Jeep vehicles between 2000 and 2023.
Year-Adjusted Scoring (v2.1): In year-by-year breakdowns, each vehicle is compared against the national average for vehicles of the same model year. This removes the natural bias where newer cars pass more often, allowing fair comparisons across eras.
Evidence-Tiered Durability: We separate "proven durability" (vehicles tested at 11+ years old) from "early performers" (3-6 years old). Only vehicles with proven long-term data are used for durability claims. Age-band comparisons use weighted national averages.
Minimum thresholds: 100 tests for proven durability rankings, 100 tests for early performer rankings. Pass rates are calculated as first-time passes, excluding retests.
The overall national average MOT pass rate is 71.44% based on 32,300,000 tests across all manufacturers. Year-specific averages range from ~59% (2009 vehicles) to ~88% (2020 vehicles).
