Most Recent Complaints
My 2015 Mercedes-Benz GL63 AMG has suffered two separate ECU failures caused by oil migrating through the engine wiring harness. The first failure occurred at ~42,600 miles in 2020, and the second at ~59,000 miles in 2023. Both times, the vehicle developed misfires, check-engine warnings, and drivability issues that could have led to stalling at highway speeds. On both occasions, the vehicle has been completely disabled. Repairs required replacement of the wiring harness, ECU, sensors, and fuse box, costing over $5,600. This is a hidden, recurring defect that poses a safety risk and financial burden. The vehicle does not feel safe or reliable to drive, and dealer support and guidance is non-existent. I have been afraid to drive to the point that it has only accumulated 3,000 additional miles in the last two years.
