Top issues to watch for

The most serious Chrysler Jeep Grand Voyager problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Suspension ball joint excessive wear
RT, RG2001–201660k–150k miles
The front suspension ball joints on diesel Grand Voyagers wear at an abnormally high rate, particularly on the lower control arms. The combination of the vehicle's weight distribution and the diesel engine's additional mass accelerates wear in the joint bearings and dust seals. MOT data shows this model fails steering ball joint tests at 10.1 times the national fleet average, with failures concentrated between 60,000-150,000 miles. This is a safety-critical component that affects steering control and wheel alignment.
What happens if ignoredBall joint failure can cause sudden loss of steering control, wheel detachment, or collapse of the suspension geometry. The vehicle becomes dangerous to drive and will fail its MOT test. Repair involves replacing the entire control arm assembly on most variants, as the ball joint is not serviceable separately.

Dangerous
Brake hose corrosion
RT, RG2001–201660k–100k miles
The brake hose ferrules (metal end fittings) on diesel Grand Voyagers are particularly susceptible to corrosion, especially where the flexible hoses connect to the rigid brake lines. The vehicle's height and ground clearance expose these connections to road salt and moisture, while the commercial-duty construction uses components that prioritise durability over corrosion resistance. MOT data shows brake hose ferrule corrosion at 5.8 times the fleet average, concentrated in the 60,000-100,000 mile range.
What happens if ignoredCorroded brake hose ferrules can fail suddenly, causing complete loss of braking to one or more wheels. This represents an immediate safety hazard and the vehicle should not be driven. Even minor corrosion will cause MOT failure and must be addressed before the vehicle can be used safely.

Major
Suspension bush excessive wear
RT, RG2001–201660k–150k miles
The rubber suspension bushes throughout the front and rear suspension systems deteriorate rapidly on diesel Grand Voyagers. The vehicle's commercial-grade construction uses softer bushes to provide ride comfort, but these wear quickly under the additional weight of the diesel engine and typical high-mileage use. MOT data shows suspension component wear failures at 322.5 times the fleet average. Worn bushes affect handling, steering precision, and tyre wear patterns.
What happens if ignoredWorn suspension bushes compromise vehicle handling and stability, particularly during emergency manoeuvres. They cause accelerated tyre wear due to poor wheel alignment control and will eventually fail the MOT test. Multiple bushes typically need replacement simultaneously due to their similar age and exposure.

Major
Parking brake system failure
RT, RG2001–201660k–150k miles
The rear drum parking brake system on diesel Grand Voyagers suffers from multiple failure modes including seized adjusters, corroded cables, and worn brake shoes. The system is particularly vulnerable to corrosion due to its location and the infrequent use typical of automatic transmission vehicles. MOT data shows parking brake efficiency failures at up to 10.3 times the fleet average, with both complete failure and reduced effectiveness being common issues.
What happens if ignoredA failed parking brake system makes the vehicle dangerous to park on slopes and will result in an automatic MOT failure. The vehicle cannot be legally parked on any incline without the parking brake functioning. Repair typically involves replacing cables, adjusting mechanisms, and brake shoes simultaneously.
