My husband and I purchased a 2006 ml500. We started to have a problem with it. I was at a store and when I tried to leave it wouldn't move. I put it in reverse and the car wants to go but it just stays in place almost like I have the parking brake on. After a long while it will start to work just fine. I have taken it to a mercedes machanic and they cannot find anything wrong with it. A few days later it did the same thing but when I take it to the shop it is not doing it anymore. and the machanics tell me that they can only diagnose the problem when it is happening. I am tired of getting stuck at places.

If anyone else has had this problem, please let me know what to do
