Chrysler Jeep Grand Voyager MOT Failures

An analysis of 29,930 real DVSA MOT tests on the Chrysler Jeep Grand Voyager — what fails, how often, and how that compares to every other car on UK roads. Generations covered: RT (2001–2008), RG (2008–2016).

Where the Chrysler Jeep Grand Voyager fails its MOT

The single biggest MOT failure point on the Chrysler Jeep Grand Voyager is coil springs broken — this model is 323 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 29,930 MOT tests, 4.2% of all Chrysler Jeep Grand Voyager tests recorded this as a failure.

Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.

Other notable weak points include parking brake efficiency less than 50% of the r... (15x the fleet average), anti-roll bar links worn (11x the fleet average), stop lamp missing, inoperative or in the case o... (27x the fleet average), and electrical wiring fault (17x the fleet average). These ratios compare the Chrysler Jeep Grand Voyager's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.

The failures span 3 categories: Suspension, Brakes, Lights & Electrics. If you're inspecting a Chrysler Jeep Grand Voyager before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.

How failures change with mileage

The Chrysler Jeep Grand Voyager's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.

Under 60,000 miles

At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.

For the Chrysler Jeep Grand Voyager specifically, the DVSA data shows the most common failures at this mileage are parking brake inoperative on one side (28x the average) and stop lamp missing, inoperative or in the case o... (27x). significant brake effort recorded with no brake... (6.3x) and significant brake effort recorded with no brake... also appear frequently.

60,000 to 100,000 miles

This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.

For the Chrysler Jeep Grand Voyager specifically, the DVSA data shows the most common failures at this mileage are coil springs broken (323x the average) and brake hoses perished or damaged (35x). parking brake efficiency less than 50% of the r... (15x) and abs fault (15x) also appear frequently.

Over 100,000 miles

High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.

For the Chrysler Jeep Grand Voyager specifically, the DVSA data shows the most common failures at this mileage are coil springs broken (135x the average) and electrical wiring fault (17x). braking effort inadequate at any wheel (12x) and headlight fault (7.8x) also appear frequently.

The shift from parking brake inoperative on one side at lower mileages to coil springs broken at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.

Known issues beyond the MOT

An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Chrysler Jeep Grand Voyager specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.

Suspension ball joint excessive wear Dangerous

The front suspension ball joints on diesel Grand Voyagers wear at an abnormally high rate, particularly on the lower control arms. Affects RT, RG; typical independent garage repair cost is £180–£280.

Brake hose corrosion Dangerous

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. Affects RT, RG; typical independent garage repair cost is £120–£200.

Suspension bush excessive wear Major

The rubber suspension bushes throughout the front and rear suspension systems deteriorate rapidly on diesel Grand Voyagers. Affects RT, RG; typical independent garage repair cost is £200–£400.

Parking brake system failure Major

The rear drum parking brake system on diesel Grand Voyagers suffers from multiple failure modes including seized adjusters, corroded cables, and worn brake shoes. Affects RT, RG; typical independent garage repair cost is £150–£300.

What to check before buying a Chrysler Jeep Grand Voyager

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Chrysler Jeep Grand Voyager:

Suspension — check for coil springs broken, anti-roll bar links worn. Brakes — check for parking brake efficiency less than 50% of the r..., abs fault, brake hoses perished or damaged. Lights & Electrics — check for stop lamp missing, inoperative or in the case o..., electrical wiring fault, headlight fault.

Beyond the MOT items, ask specifically about suspension ball joint excessive wear and brake hose corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £180. A specialist pre-purchase inspection is worth the investment on this model.

Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
