Interior door handle/panels have come loose.
Had serious problems with the retractable roof.
Arm in passenger window suddenly broke and had to purchase new window which shattered shortly after being installed and was still at the dealership. Dealership said the window is very touchy and they paid to have a third window shipped and installed.
I paid 4 times to have a new rear light installed because it continually burned out. Mercedes Benz eventually recalled the part and I haven't had a problem since.
Interior vinyl paint has chipped consistently since I bought the car in 2003. Leaves large black spots in the interior.
Have not been able to use the integrated phone system yet.
The dealer finally figured out that the retractable roof was getting stuck down and up because of a lack of hydraulic fluid. The dealer said that it should never need to be replaced, but they were replacing it every summer. The dealer said that he sealed it extra tight the third time, and I haven't had a problem with it since.
My 1999 SLK 230 is Baja Blue with the black and white interior and looks great with the top down. This car is seriously fun to drive and I love the supercharged pick up and the way the car handles on turns. I just need to deal with the chipping interior paint and the loose door handle panels. The baby smart system also works like a charm when I need to turn the front airbag off.
This is my second Mercedes Benz. The first was a 1991 190E 2.3 which I loved but had to sell for a vehicle with more seats when we were expecting our fourth child, otherwise I would never have sold that car. I love the Mercedes cars I've owned.
