i had my car only few months and im already having problems.

My gas gauge is broke, when i fill up my car it only goes up to 3/4ths but it shows the correct miles on the electric speedo.

Next the sun shade for the roof of my car is stuck all the way at back and when i try to slide it back it makes a weird noise and wont slide.

my navi is also not working the screen just stays black but everything else works lol.

 

wow, i have no problems with my coupe. everyday i get in it i love it even more. but hey it happens.... take it in let them fix it

 

OH ya I love the luxury and speed, by this summer i will have my car running mid 12s@111

 

Must be the vacuum in the fuel tank when you floor it, and the G-forces push the sunshade to the rear and black out the Nav. Try slowing down and check them again.

 

Sorry to hear of your problems. As someone with a long list of problems on
my E550C I know how it feels. Please see my other posts for details, but
yours are completely new from what I searched in the web. I had Parktronic
sensor problems, seat belt module failure that took a long time to fix, and
now Key-less Go. The Lniguatronic almost never recognizes names and
always presents me with a list of names that bear no resemblance to what is
stored. My service manager tried it too and his voice was not recognized
either but he tell me the feature performs as designed - and that is that

The Navi does not show any / few street names, and has old or
improper driving data programmed into it, unlike a Garmin for $200...

I think in a short time more quality / design problems will start tricking in on
the C207 and W212 for that matter, because even tough they are
completely different cars, they share much of the ill designed electronics and
software.

I hope you will get those problems fixed. Would you give us followup?
