2004 Chrysler Grand Voyager — MOT failures & pass rate
2,099 MOT tests on the 2004 Chrysler Grand Voyager are in this dataset, and 69.6% of them passed. That is effectively the same as MPVs of a similar age (30.1% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (19.3%) and brakes (18.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), headlamp aim and component mounting prescribed areas — rbt (sp) alone was recorded 197 times.
Condition tracks the odometer closely. Failures run at 23.6% in the 30-60k band and 36.9% in the 150k+ band, a 13.2-point spread.
The petrol cars hold up better: 28.2% fail against 31.9% for diesel, a 3.7-point gap across 2,095 tests.
Brakes is the most common advisory, noted on 43.2% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 31.3% in 2021 to 27.9% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2004 Grand Voyager
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.3% of tests. Start there.
- Lighting & signalling (19.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (18.7% 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.
- Suspension (14.1% 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.
