When driving my '06 C350 with 48 thousand miles, yes 48K on it, the transmission seems to go into a safe mode. It normally occurs when driving at highway speeds and have to slow down gradually, then upon acceleration the transmission just revs up the RPM with no power. I'm afraid me and my two children will be rear-ended due to the loss of power in the transmission. I then try to drive it to the next exit, shut off the engine and restart. This normally resets everything to normal. But it could occur again minutes or hours later which is now getting frustrating given the car is barely reaching 50K miles. So this happens intermittently, unexpectedly, and with varying frequency. Mercedes Benz usa should have a recall on this as when I call the dealership they know exactly what happened and it's a very well-know defect that costs a considerable amount to repair. This car started doing it at 40K and does it often. I've notified my lawyer because I'm afraid it could happen with a vehicle behind me and thus cause an unexpected rear end impact from another driver on the highway.

My sprinter 2500 diesel van year 2006 just shuts down without any warning. I am driving along on a main street in savannah and the van just shuts down without any warning. It has happened about 8 times since I bought the van. They keep replacing the alternator but that is obviously not the answer. I need help. My husband is totally wheelchair bound and he is in the van. I really need help!
