Software Problems of Mercedes Benz E350

The collision prevention assist module warning light came on. Collision assist was inoperative. This can lead to loss of acceleration and braking. I took the vehicle to local dealership, Mercedes Benz of arcadia, who performed a software update and charged $205. Oo. This is a safety issue and should be a recall and free of charge. When the error message came on my wife was on the freeway. She panicked and pulled over to the shoulder. Restarting the engine did not solve the problem. She drove home slowly whereupon we went to the dealership.

While driving on the highway, I attempted a heavy acceleration to get the car up to traffic speed. Two times in the past 60 days, the car seriously malfunctioned with multiple dashboard indicator lights and the main text "pre safe functions limited" accompanied by a total loss of speed control. The accelerator became 100% unresponsive and I had to coast to an emergency lane. There was significant danger in both instances as I had to cross multiple lanes of traffic with no power to get to safety. The weather was clear and the external sensors were not obstructed by dirt or snow- which has previously caused the pre-safe functions limited message. I believe that the multiple errors indicated on the dashboard are all erroneous to the core issue of a sudden and total loss of power upon heavy acceleration. The resolution was to shift the car into park, push the ignition button as if turning the vehicle off, wait and restart. The car operates normally upon restart. Note that the engine appeared to already be off prior to shifting into park. It is as if the heavy acceleration killed the engine. This issue has potential fatal consequences if the driver is unable to get the car out of the lane of high speed traffic-- as I was in. A less experienced or panicked driver could easily fail to handle the situation and get rear ended at high speed as the car can only be reset by getting it into park and restarted. Similar blog posts online report the same with other mercedes vehicles. I have had the car for four months and it has happened twice. Seems like a software/electronic issue causing the mechanical issue to me. Very dangerous.
