Chrysler Jeep Grand Voyager MOT pass rate & common failures
Across 23 model years and 9,980 tests, the Chrysler Jeep Grand Voyager passes its MOT 70.9% of the time. That is 3.0 percentage points worse than all cars of a similar age, which fail at 26.1%. Its most common failure areas are brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (18.1%) and lighting & signalling (17.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), position lamp and stop lamp — rbt (sp) alone was recorded 997 times.
A 150k+ example is materially riskier than a 0-30k one: 31.0% versus 24.7%.
Split by fuel, diesel examples fail 2.0pp more often than petrol ones (29.4% vs 27.4%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 33.5% of tests without failing them.

What to check before buying a Chrysler Jeep Grand Voyager
- Brakes (18.1% 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 (17.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.5% 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.
