Bought a new S65 a little over a month ago. So far, the car has been in the service department for 14 days (and its still there now). Check engine light keeps coming on - cylinders not firing right - waiting for software update from Mercedes corporate. I was understanding at the beginning of the process but now that I have been without the vehicle for sometime its really getting to me - especially given the fact that my monthly payments are not small. So, I'm making my payments without the use of the car. Any advice for course of action? I know that reading my state lemon laws they say that to be considered a lemon the car must be in service for a combined 30 days within the first 18 months. So, we aren't there yet. But I should be compensated in some way, correct?
