Yes...i have a 2001 ML320. Didn't have it for more than 4 months. I didnt have a crack, but the whole plastic panel just fell off. This car has given me hell. I have had this damn car in the shop over 10 times. What a lemon. It drives and feels like an american truck.
I just went to the dealer and complained, they gave me a free keychain. whoopee...
