2013 MERCEDES-BENZ Amg ML63

On December 6, 2025 I purchased a used 2013 Mercedes-Benz ML63 AMG from Jaguar Land Rover Willow Grove (Piazza Auto Group) in Pennsylvania. The delivery documentation for the vehicle included a written service commitment stating: “Replace air compressor for suspension system.” On January 23, 2026 at approximately 6:30 PM, while operating the vehicle at highway speed on the [XXX] in [XXX] , the vehicle experienced a sudden cooling system malfunction. An “Engine Overheat – Shut Off Engine” warning appeared on the instrument cluster and steam began emitting from the engine compartment. Because the failure occurred while traveling at highway speed, the driver was forced to execute an emergency maneuver across traffic lanes in order to reach the shoulder safely. The vehicle became disabled and required towing. The vehicle was transported to a Mercedes-Benz dealership for inspection. Initial repairs involved replacement of the coolant reservoir and hose assembly. Within several days the vehicle again displayed a low coolant warning and was returned for further inspection. At that time the radiator was found to contain a prior non-OEM epoxy repair and the radiator required replacement due to leakage. During a separate independent inspection, the air suspension compressor was observed to be mounted using plastic zip-tie fasteners rather than mechanical mounting hardware. The compressor is part of the vehicle’s AIRMATIC suspension system and is subject to vibration, pressure cycling, and heat during normal operation. Improper mounting of this component could allow the compressor assembly to move or detach during operation and may damage associated air lines or electrical connections. Because the air suspension system affects ride height and vehicle stability, this condition may present a safety risk during vehicle operation. Photographs and video documentation of the compressor mounting condition are available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.

I was driving from Florida to my home in Washington, DC on September 4th, 2023 on I-95. Somewhere in South Carolina, a message appeared on my display that said the blind spot assistant was disabled. Soon thereafter, my turn signals quit functioning. At first chance, I pulled over and turned the car off hoping it was some kind of computer reset. That worked but only for an hour or so. I made it home ok but not having turn signals was very dangerous and very concerning. I took the car to a local DC Mercedes mechanic who ran a diagnostic but nothing came up because the systems were functioning at the time. He took the car for a drive and they stopped working for him. He said take it to a dealer. I have an appointment for next week. I also have searched for this problem on social and it is definitely a problem with other owners. The part is nearly $700 and it is a big job to pull the steering wheel and replace this. I think this is a serious flaw and consumers should not be burdened with non-working turn signals. I think it might be a design flaw in their switch. Please look into this if you think as I do. Thank you.

THE BRAKES ON MY BRAND NEW 2013 MERCEDES BENZ ML 63 AMG SCREETCHES/SQUEALS WHEN SOFT BRAKING TO A STOP. I HAVE BEEN TOLD BY THE MB DEALER IS WESTMINSTER, CO THAT THIS IS NORMAL AND I NEED TO BRAKE HARD IN ORDER TO STOP THE NOISE. THIS AWFUL NOISE DID NOT HAPPEN WHEN I FIRST STARTED DRIVING IT A FEW WEEKS AGO. IT STARTED ONLY RECENTLY AND IT IS GETTING LOUDER AND LOUDER WHEN COMING TO A STOP. THIS COULD BE A POTENTIAL DEFECT WAITING FOR A DISASTER. THIS SHOULDN'T BE HAPPENING TO A CAR THAT IS BRAND NEW AND COSTS OVER $100,000. *TR..UPDATED 01/30/13 *BF THE CONSUMER STATED THIS IS NOT AN ISSUE. THE BRAKE NOISE IS APPARENTLY NORMAL FOR AMG BRAKES. THIS IS NOT A POTENTIAL DEFECT MATTER. UPDATED 2/4/2013 *JS
