C10C8

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. This loss of power has occurred to me at least 3 times at low speeds (10-25 mph), once at 45 mph and once at 65 mph while driving in the far left lane of 73 south toll road, california. Also important is that at the time forward power is lost, the regeneration gauge on the far right of the dashboard moves immediately to maximum indication and all warning lights become illuminated. During the first dealer service on july 24, 2015 the dealer found code message U029887, U016883 and U029287 missing. Dealer performed a software update and updated ptcu drivetrain n127 module. The dealer has replaced the ptcu drivetrain n127 twice - once on service dated july 29, 2015 and again on service dated august 28, 2015. On service dated july 29, 2015 dealer replaced drivetrain gateway module n93/8. Found code C10C800 not related. On service dated august 28, 2015 dealer retrieved all data from ptcu drivetrain module n127. Owner has videotaped the loss of power occurring and provided it to dealer. Owner's children are frightened to drive in the vehicle. Teenage daughter was very frightened driving at 65 mph when she experienced unexpected total loss of power and had to drift into the the left shoulder of a busy freeway and restart the car after coming to a stop. Mercedes and tesla - you have a lemon!
