Isuzu D Max Problems & Known Issues

The D-Max shows exceptionally high rates of suspension component wear, particularly bushes, ball joints and anti-roll bar links. MOT data shows this model fails at up to 85.8 times the fleet average for suspension bush and joint wear across all mileage bands. This is attributed to the commercial vehicle chassis design and heavy-duty use patterns, where suspension components face higher loads than typical passenger cars. The problem affects both front and rear suspension equally and is progressive rather than sudden failure.

D-Max vehicles show wheel bearing failure at 55.8 times the national fleet average, with failures occurring across all mileage bands including unusually early failures at 20,000-40,000 miles. This is likely due to the commercial vehicle specification and heavier loading compared to passenger cars. Both front and rear bearings are affected, with the problem being progressive - bearings develop play gradually before eventual failure.

D-Max vehicles with towbars show failure rates 72.8 times higher than the fleet average for towbar component damage, corrosion, or fracture. This affects the 2.5L diesel variants most severely and is likely related to the heavy-duty towing use these vehicles typically see. The failures include towbar mounting point corrosion, electrical socket damage, and mechanical component fracture due to repeated loading cycles.

MOT data reveals D-Max vehicles fail at This typically manifests as CV joint failure, propshaft universal joint wear, or transfer case components on 4WD variants. The commercial vehicle duty cycle and potential for overloading contributes to accelerated wear of these drivetrain components compared to passenger cars.
