  • Service Brakes, engine 09/25/2025

    I was coming off the freeway on 9/25/25, and when I pressed on the breaks they completely locked up and would not break at all. The car turned off, no warning lights nothing, and I continued to hit the break and the car would not stop, then all of a sudden it came to a stop almost colliding within inches of hitting the Semi-Truck in front of me.

  • Steering 09/08/2025

    The "ESL Module" in this model is designed to unlock the steering and ignition when the vehicle key's passcode matches, using a small, mechanical motor with significantly poor durability. The problem is that this motor's failure is unpredictable, and many users of this model have been stranded and unable to start their vehicles due to the motor's lifespan ending. Even when the car is painstakingly brought to a dealership, repairs cost approximately $1,800 to $2,000, or owners are resorting to unofficial bypasses using a device called an ESL Emulator from the aftermarket. I'd like to request NHTSA to start a thorough investigation into this issue and a RECALL order for the affected models to be issued to MBUSA. Thank you.

    Leaving my home from my driveway and driving about 15 feet I heard a loud pop from my backseat area and noticed my Headrest on drivers side deployed without any reason.

The dealership Removed old headrest and replaced with a new one , reset malfunction light and a fuse. Price was enormous.
