2014 Mercedes-Benz GL 3.0L Diesel · JO53 TEE

The vehicle is currently roadworthy, but the maintenance trend shows a concerning pattern of deferred mechanical repairs. The most recent test on 16 January 2026 at 115,346 miles resulted in a failure due to an inoperative engine malfunction indicator light, insufficient washer fluid, and a deteriorated nearside front CV boot. While the vehicle passed immediately upon rectification, the recurring nature of the CV boot failure suggests that the owner only addresses faults once they fail inspection rather than performing preventative maintenance. At 115,346 miles over approximately twelve years, the GL has averaged roughly 9,600 miles per year, which aligns with typical annual usage for a large luxury SUV. The mileage data shows consistent usage intervals, with approximately 7,000 miles covered between the November 2024 and January 2026 tests, and roughly 6,700 miles between December 2023 and November 2024. This steady accumulation indicates the vehicle is used regularly, which is generally preferable for seals and components of this age. A buyer must scrutinise the front drivetrain assembly specifically, as the nearside front drive shaft joint CV boot has been flagged as severely deteriorated in three consecutive tests dating back to 2023. This persistent issue indicates a failure to replace rubber boots when torn, which will eventually lead to catastrophic joint failure and expensive damage to the gearbox or axle. Additionally, the 2024 record noted a non-excessive oil leak and misting on the nearside rear shock absorber. These areas should be inspected for active weeping to ensure the leaks have not progressed beyond manageable levels. The braking system also requires a close look. The December 2022 test identified pitted and scored front brake discs while the 2024 test flagged an incorrectly fitted offside front brake pad wear sensor. Given the engine malfunction light failure in the latest January 2026 test, a professional diagnostic scan is essential to ensure no hidden fault codes remain stored in the control module. The history suggests a vehicle that is maintained to the minimum legal standard, necessitating a thorough physical inspection of all suspension and fluid components before purchase.
