2006 Mercedes-Benz ML 3.0L Diesel · MH06 XPM

The overall roadworthiness status is currently Pass, but the maintenance trend is deteriorating rather than stable or improving. The most recent test on 2026-06-18 at 160,458 miles was passed, yet this does not negate the underlying issues revealed in the previous year's record. The failure on 2025-07-15 at 160,454 miles indicates a significant drop in performance that was likely a result of accumulated wear rather than a sudden mechanical failure, suggesting the vehicle has been in service for roughly 16 months. This pattern of consistent passing with a gradual decline in mileage suggests that the vehicle has been maintained in a relatively good state for the first year, but the subsequent years of reduced mileage indicate that the vehicle is no longer in a state of continuous, high-maintenance operation. The mileage pattern is heavily skewed toward rapid accumulation over a short period, particularly from 2025 to 2024. The vehicle has experienced significant mileage loss in the first two years, dropping from 160,458 miles in July 2025 to 156,071 miles in July 2024, a reduction of approximately 4,387 miles. This rapid accumulation suggests that the vehicle has been used for a substantial period without any meaningful maintenance, leading to the loss of critical components such as the engine oil and the brake discs. The fact that the vehicle has maintained a passing rating for two consecutive months (July 2025 and July 2024) despite this rapid mileage loss indicates that the vehicle is not currently in a state of continuous, high-maintenance operation, which is a major red flag for future reliability. In terms of recurring faults, the mechanical condition of the vehicle is compromised, particularly regarding suspension, brakes, and structural integrity. The most serious issues identified include a severe deterioration of the constant velocity boot on the front and rear driveshafts, which has caused grease to seep out and compromise the drivetrain. The brake discs are corroded and pitted, and while not excessively weakened, this indicates that the braking system is no longer fully functional and is prone to failure under load. The front and rear suspension bushings are worn, and the lower arm rear bushings are starting to perish, suggesting that these components are likely to fail soon if not replaced. The oil leak from the engine running down the exhaust system is a serious hazard that requires immediate attention to prevent catastrophic failure.
