2004 Chrysler Jeep Grand Voyager — MOT failures & pass rate
429 MOT tests on the 2004 Chrysler Jeep Grand Voyager are in this dataset, and 69.0% of them passed. All cars of a similar age fail 27.7% of the time, so this is 3.3pp worse than the group it competes with. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (20.8%) and lighting & signalling (18.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), component mounting prescribed areas and headlamp aim — rbt (sp) alone was recorded 50 times.
Condition tracks the odometer closely. Failures run at 24.7% in the 60-90k band and 34.4% in the 150k+ band, a 9.8-point spread.
Advisories point at the next bill rather than this one: brakes was flagged on 48.5% of tests without failing them.
The trend is worsening — 27.1% of tests failed in 2021 against 34.9% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 48.5% | 208 |
| 2 | Suspension | 39.9% | 171 |

| 5 | Lighting & signalling | 28.7% | 123 |
| 6 | Emissions & environmental | 27.5% | 118 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

What to check before buying a 2004 Grand Voyager
On a 2004 Grand Voyager, brakes is what the MOT record says goes wrong most — it appeared in 20.8% of tests. Check these areas before you commit.
- Brakes (20.8% 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 (18.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (13.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
