2014 Mercedes-Benz E350 driver assistance complaints

Filed Mar 31, 2015 · Driver assistance, Engine · 1,100 miles · WA

While driving on a side street looking for an address, a warning message appeared something like "lane guidance system inoperative". Subsequently, the engine lost power and would not move the vehicle more than about 3 MPH. We pulled off to the side, not knowing what to do. I shut off the engine and restarted it and it appeared to work normally for the rest of the trip home. We wonder what would have happened if we had been in a middle lane on a freeway when this happened. I plan on contacting the dealer today for more information and to have them inspect the car.

The technician was unable to replicate and diagnose the failure. The contact waited longer than six weeks for a response from the dealer who indicated that the concern was to be escalated to the manufacturer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 3,000.

Cruising at 65 MPH the ESC lights came on and the car lost power. It no longer responded to the accelerator and required that you pull off the road, come to a stop, and restart the car. This same problem has happened 3 more times once at 35 MPH on a straight road; once at about 20 MPH making a turn and again cruising on an expressway at ~50 MPH. This is an extremely dangerous defect, since a failure of this type when entering a highway or trying to overtake another vehicle could cause a high speed accident, resulting in serious injuries or fatalities. The car has been to the dealer twice to fix this, and is now back for the third time.
