I wasn't happy with my sales experience when I bough a CPO S550 in February and I wrote some pretty scathing comments about my interactions with the GM. My salesman told me that my comments sent shock waves through the dealership. In the 2.5 months that I've owned the car, I've had to take it back for several warranty issues.

Incident #1:
My CD's were stuck in the changer. It took them a couple of days to even look at the car. Once they got to it, they said they had to replace the COMMAND unit and send the defective changer back to Germany per MB policy. I question whether or not they really replaced the COMMAND unit because the second page of radio presets were still stored in memory when I picked up the car. Everything else was deleted. Was it possible that they really didn't replace the COMMAND unit but just wanted it to appear that they did (and did a sloppy job of deleting the memory) to justify keeping my car for a week in an attempt to inconvenience me??? They also told me that it would take 6 months to return the CD's that were stuck in the changer. Another attempt to inconvenience me?

Incident #2:
Since they installed the new COMMAND unit, the digital clock on the screen and the analog clock on the dashboard have been malfunctioning. Although I scheduled an appointment in advance, they didn't get to my car for a couple of days. After they finally got to it, they called to tell me that they lost my key and asked if I could bring the second key to the dealership. After several more days, they still haven't been able to solve the issue and said they had to open a repair ticket with MB. By this time, they "found" the lost key but the bottom line is that it's been over a week and they still haven't fixed the clock yet. I have a C-Class loaner but I can't help but wonder if this is another attempt to inconvenience me.

I can't believe that fixing a clock is this difficult. Am I paranoid or are they intentionally inconveniencing me in retaliation for my scathing customer satisfaction survey comments???
