2003 Mercedes-Benz ML 2.7L Diesel · GL03 UEP

The vehicle shows a history of recurring mechanical and structural issues, particularly concerning the braking system and suspension. The latest test in October 2025 at 172,026 miles passed, but with several significant advisories that indicate a need for immediate attention. Both the offside and nearside front brake pipes were flagged as corroded, alongside deteriorated front brake hoses. The tester also noted severely deteriorated ball joint dust covers on the front lower suspension arms and general underbody corrosion. Notably, the rear parking brake only barely met the efficiency requirement, suggesting the system is nearing the end of its effective range or requires adjustment. At 172,026 miles over 23 years, the ML has covered an average of approximately 7,500 miles per year, which is consistent with typical usage for its age. However, the record reveals a persistent pattern of oil leaks from the engine and rear differential dating back to 2023. While these were often described as not excessive, their persistence across multiple years suggests seals are not being addressed. The failure in October 2024 at 167,883 miles, due to a broken offside rear coil spring and a parking brake failure, highlights that heavy-duty components are now experiencing significant wear. Structural integrity remains a long-term concern, as the 2021 test identified corrosion on the offside front inner integral structure. While the rigidity was not deemed significantly reduced at that time, the general underbody corrosion has appeared in almost every test since then. A potential buyer should carefully inspect the sills and chassis points to ensure the rust has not progressed beyond what was noted. The recurring nature of minor lighting failures and wiper blade issues alongside deeper mechanical leaks suggests a vehicle that is maintained in a reactive rather than proactive manner.
