“My 2015 mercedes benz b class electric drive lost power during my evening commute today leaving me stalled in traffic. I was not able to make it across all 5 lanes of a busy freeway to the shoulder before coming to a complete stop halfway between two lanes (one of which was a busy merge lane from sfo airport). I tried to restart it (keyless) a couple of times without success- no messages on dash, rest of electronics (radio etc) still working fine. …”

“I was driving at 55 MPH on the freeway with both hands on the wheel when all of a sudden I lost power to the accelerator pedal. No mechanical problem was indicated on the dash: the car was 'ready' and was in 'd' yet I had no power whatsoever to the accelerator pedal. I could not pull over to get out of trouble because I was surrounded by fast moving traffic and had no power. I could not brake to try to restart the car without being rear ended by the considerable traffic behind me on the freeway. …”

“My B-Class Electric had a sudden loss of power. Here's the details: left the house in san diego at 7:00 am. Outside temperature about 75+degrees. About 1 mile from the start, I braked slightly to maintain speed of about 25 MPH, coasted towards and uphill, put my foot on the accelerator to maintain speed and there was no power-just coasting. There was no unusual sound and no warning displayed. The car appeared normal except the guage was showing full regenerative braking while the car was coasting. Transmission was in d-auto. Power steering worked, AC and radio were still on. …”

“I was driving on the 91 freeway in anaheim ca when my brand new (approximately 1000 miles on the odometer) 2015 mb all electric automobile began to decelerate. My foot was on the accelerator as I lost all power to the engine. The battery was fully charged. The radio and all of the electronic interior features were intact. I was in the 3rd lane of traffic (out of 5). Luckily the traffic was light as I pulled over to the side of the freeway and the car came to a complete stop. I was quite unnerved by the incident but the car started up and I continued my commute to work uneventfully. …”
