Driving slowly through a parking lot and had to stop for pedestrians. When the path was clear, the car would not accelerate. It only idled forward and slowly reached about 5 mph. Stepping on the accelerator pedal gave no response after repeatedly trying to accelerate. No warning lights came on to alert me of a problem. I was able to pull into a parking spot and after shutting off the ignition and turning back on, the throttle responded as normal.

Entire front right headlight assembly and module failed with no headlight, turn signal, park light etc. There is no visible external damage to the assembly although there is some moisture inside assembly. From internet search, it appears that this is a very common failure. Cost is over $2500 for replacement from local mechanics and over $3300 from Mercedes dealerships with little to no warranty for future failures either.

Vehicle left/front headlight has water condensation and entire headlight doesn't work. Its pretty much not drivable. I brought the vehicle to a manufacturer dealership and they claim that the failure of the headlight is due to physical impact to the exterior of head light. There is a minor scratch barely visible and no cracks or physical damage to the headlight or seal, or car or that matter. When I asked if they performed an inspection due to a recall associated with the headlight (recall # 2022050005), they confirmed that they did not inspect…

The car abruptly slowed me down to 35 because it saw an exit sign speed limit but I was not on the exit. I was lucky the car behind me didn't hit me.
