One problem related to warning has been reported for the 2012 Mercedes Benz ML350. The most recently reported issues are listed below.
The turn signals stop working after driving the car for a few minutes. To get them to work again requires stopping the car, shutting off the engine and restarting it which in turn resets the computer. This effort does not permanently fix the issue and they usually quit working again within two to ten miles. This is the fifth complaint to the NHTSA with this issue and this particular model. This is a safety hazard which needs to be addressed by the manufacturer and fixed free of charge. This has been an ongoing issue for the past two to three years with this car. Today we were almost rear ended when making a left hand turn off of a two lane road without a designated turn lane.
