 Issues during the first two years, I am 
on my third fuel tank (service 
department can not figure out why the 
check engine light comes on, but 
three's a charm??), driver window would 
not go up (repaired twice because the 
second time is always better), Gear 
shift at times will not go out of Park, 
CD Changer "not installed" , rear hatch 
would not lock, sunroof cover cracked, 
headlight washers would not pop up, 
trip computer went out, etc... By the 
way, at the dealer I use in Denver the 
Service Advisors are paid on commission 
based on the Labor portion of the 
bill.  Keep the customer coming back 
in, "we hope your car falls apart" is 
what Mercedes is telling us.
