Report: Sunroof Components May Fail Due to Age and Wear
Mercedes-Benz E420 Problem
Average Mileage: 131,500 mi (75,000 mi - 188,000 mi)
The sunroof may not work correctly due to failed components as a result of age and wear. Repairing a sunroof can be labor intensive and very costly.
Goopy, tar like adhesive, bits of gasket material breaking loose, jamming between sunroof lid and roof. Scratched sunroof paint; squeaking.
Over time, I think most of the broken gasket material has come out, but the sunroof still squeaks and something still scrapes the paint. Terrible design!!
I would like to try to fix myself someday.
sunroof does not open or close have to manually crank open the rook or pop top what is the solution
