THE VEHICLE MISFIRED WHILE DRIVING ON CITY STREETS AND PRESENTED A CODE FOR FAULTY IGNITION COILS. UPON INSPECTION, MERCEDES-BENZ SERVICE CENTER FOUND OIL IN THE ENGINE WIRING HARNESS RENDERING THE CAR UNDRIVEABLE.
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, recurr…

Reported: 2016-12-14 (December 14, 2016)
Mercedes-Benz USA, LLC.

The affected vehicles have axle bolts on the front and/or rear drive axle carriers that may not have been assembled correctly. As a result, the remaining bolts may fracture.
Consequence: If any of the remaining front or rear axle bolts fracture, the vehicle may be unstable, reducing the handling capability and increasing the risk of a crash.
Remedy: MBUSA will notify owners, and dealers will replace the axle carrier bolts, free of charge. The recall is began February 2017. Owners may contact MBUSA customer service at 1-800-367-6372.
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2012-2014 ML350 Bluetec 4Matic and ML550 4Matic, 2012-2015 ML63 AMG 4Matic and ML350 4Matic, 2013-2016 GL350 Bluetec 4Matic, GL550 4Matic and GL63 AMG 4Matic, 2017 GLS350d 4Matic, GLS450 4Matic, GLS550 4Matic and GLS63 AMG 4Matic, 2015 ML400 4Matic, 2016 GLE400 4Matic, GLE350 4Matic, GLE63 AMG 4Matic, GLE63S AMG 4Matic, GLE450 4Matic Coupe and GLE63S AMG 4Matic Coupe, 2015-2016 GL450 4Matic and 2013-2014 GL450 4Matic vehicles equipped with the Active Curve System (ACS). In certain driving conditions, if the oil level in the ACS reservoir is below the minimum level, the oil may foam and leak out of the vent holes in the reservoir cap.
Consequence: The leaking oil in the presence of an ignition source can increase the risk of a fire.
Remedy: MBUSA will notify owners, and dealers will correct the oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out, free of charge. The recall began August 30, 2018. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2018070015.
Mercedes-Benz USA, LLC.

For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf
Consequence: An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.

THE CAR RAN OUT OF BRAKE FLUID - THERE WAS AN INDICATOR AND WHEN TAKEN TO SERVICE WE WERE TOLD THE RESERVOIR WAS EMPTY. WHAT IS ALARMING IS THAT THE CAR IS SERVICED VERY FREQUENTLY AND ONE SET OF BRAKES WAS RECENTLY REPLACED (ABOUT 6 MONTHS). MOREOVER THE DEALER STATED THERE WAS NO LEAK.
