2019: “Automatic steering followed random stripe on I 20 making the car lung to the left lane and almost going into the median iwas was going 75 in rain could have wrecked if I did not correct in seconds!”
NHTSA complaint #11171517, filed 2019-01, 1,000 miles2021: “48Volt battery failed after three months and just 3,400 miles. I understand this is a recurring problem with Mercedes. Car had to be towed as the vehicle was totally inoperable due to battery malfunction. It took more than three weeks for Mercedes to provide a replacement battery. From what I have read, there is a strong likelihood that the battery will fail again.”
NHTSA complaint #11427592, filed 2021-082023: “I had just left home and was about two blocks from my house when the engine stopped running and the word “malfunction” appeared on the display. It would not restart until I hit the off button and then I restarted it. Definite safety issue if I had been on the freeway or a busy street.”
