High Severity Issue
This component has been associated with crashes, fires, or deaths.
This Problem Across All Years
Over ~3 years of ownership, the vehicle has experienced recurrent electrical and engine-management issues, resulting in 15+ service visits and ~100 cumulative days out of service at an authorized dealer. Patterns include: (1) electrical—keyless entry intermittently unresponsive, instrument cluster flickering/rebooting, multiple warning messages including a battery/electrical icon, HVAC/A/C becoming inoperative without cooling; and (2) powertrain/engine—check-engine light (MIL) illuminated, hesitation/limited power on initial acceleration, and rough operation after start. Safety risk: intermittent failure to unlock/start can leave occupants stranded; loss of power/hesitation creates risk when merging or crossing intersections; multiple warning messages/flicker are distracting; and loss of A/C in hot conditions has required operation with windows down to avoid heat stress. Reproduction/confirmation: The concerns have been observed by the dealer on multiple visits with fault codes recorded (codes UNKNOWN to me). Repairs/updates have been attempted, but symptoms recur after service. The vehicle has been inspected repeatedly by the authorized dealer and remains available for inspection upon request. Warnings/symptoms prior to failure: intermittent MIL, battery/electrical warning, cluster glitches/flicker, and A/C blowing warm air; some events followed periods where the vehicle would not unlock or start on the first attempt. Root cause: UNKNOWN.

Check engine light came on few occasions. Took to the dealer and told it’s just a false alarm no problems. On the night of sept 12th 2024, I’m my way home I lost the ac cooling all of a sudden. I was only 5 mts from home. Once inside my garage I saw to my horror some smoke coming from under yhe hood. Upon opening saw some charred wires and some wire smoldering and smoke was coming out of it. Scared for my family I parked my car outside overnite and called the dealer. They had the car towed away the next day. Got my car back on 6 th of November 2024, with a laundry list of problems and issues, that they had supposedly fixed. Three or four various engine wiring harnesses were replaced, due to charring or melting, probably due to the heat. The engine and transmission were lifted off to fix all the wires and what not. I have all the invoices. And video and pictures of some wires and smoke. They don’t have an explanation for this. The recent recall about ecu maybe suggests the overheating of engine and causing the wires to burn out and some wires started burning almost causing fire if not caught in time. Called Mbusa and they didn’t show any concern. But one week after this incident they issued that ecu engine heating warning. Off course there is no repair for that. This is a fire hazard waiting to happen.

While driving on the freeway at approximately 40 mph on May 10, the yellow check engine light came on. I was approximately 200 miles into the current tank of gas, I stopped and checked to make sure the gas cap was properly secured. There were no obvious drivability issues. I immediately dropped the car off at Mercedes of Ontario, California, and they were able to confirm the problem, but could not clear the code, or determine the root cause of failure. Ontario Mercedes has now had my car for 6, days and that they are waiting for a M/B factory technician to tell them what to do.
