Occasionally the car will lurch forward when coming to a stop. As you come to a stop it tries to propel the car forward as you are breaking and coming to a stop. Happens rarely but when it does it's a big safety concern.
Failure of seals and or bearings in the electric motor causing coolant to leak into the electric motor, creating an internal electrical fault, seizing electric motor.
The car started to make a soft ticking sound. I bought the car at 11121 mile on july 2,2018 last week I had the mercedes benz dealer pick. The problem was the engine needs to be replaced. Mileage on car now is 28452. Asking 17,000 dollars for repair.
Car stalled while going on expressway at 30 mph. Complete loss of power. Had to pull over and power off the car. Restart of the car after a while and everything was back to normal.
Car was stopped and the engine turned itself off. Restarted manually. Took the car to the dealer for reprogramming. Did the same thing again.
3xs I have had the car stop working while driving. All three occasions while coming to a quick stop the car quit working. I had to come to a complete stop, put the car in park and restart the vehicle. I leased the car in july/august 2015, last incident was on 9/22.
Unexpected loss of power - we have experienced total loss of acceleration and throttle power resulting in the vehicle rolling/drifting to a stop. In order to regain throttle power, the car must be placed in park and the engine start button depressed.
