Instrument Panel problem #1

The contact owns a 2003 mercedes Slk320 ( n/a). While driving at various speeds , the vehicle loses power without any warning and after the vehicle loses power all the lights illuminates on the instrument panel. The vehicle was towed to his residence. This has occurred 10 additional times. The dealer was contacted and they concluded that it was the k40 circuit fuse that failed. The fuse was replaced at the owners expense. The failure mileage was 74000 and current mileage was 76000.

Ignition Switch problem #2

Mercedes with 23,000 ignition switch will not turn. I reported the issue of intermittent problem to dealer and attempted to have it resolved while under extended warranty period. The dealer said it had not failed. Well, the warranty is gone and the failing part failed. It is expensive and appears to be a known issue based on my discussion with other owners and complaints here.

Car Will Not Start problem #3

I inserted the key in the ignition switch and was unable to turn the key or remove the key and the car would not start. I was left stranded in a bad section of town and had to wait for flat bed to take the car to the dealership. I had to rent a car for three days while the dealership replaced the entire ignition switch.
