I just had to have my 5 month old C320 towed to the dealer for the second time, with the same problem - dead battery.
The first occasion occurred in mid-June when the power seats and power steering wheel adjustment decided to stop working. Four days later the battery was dead and I had no electrics at all and the car was towed to a dealer. The dealer fixed the seat problem, but could not find the cause of the battery drain. Then last Thursday the seats and steering wheel problem surfaced again. I went to the dealer but they did not have time to do anything. They did say however, that they thought the problem was caused by the dealer installed XM Radio incorrectly wired in. Then last night (Sunday) I had a dead battery again and had to be towed.
Why did they not tell me this the first time when they tried to fix it????
Anyone else experiencing such problems?
