While driving the vehicle on a freeway a light came on stating all systems would shut down and all systems did shut down immediately. There was hardly time enough to pull over to the side of the road. Even the onstar system was inoperable to call for assistance. The door fob would not work to open the car doors. The car was towed to the nearest dealership. The tow company was unable to place the car in neutral so skates were used to place the vehicle on a flatbed tow truck. The Chevrolet dealership, singh, riverside, ca that received the tow vehicle stated the problem was due to 3 defective fuses that had something to do with the battery system of the vehicle. I was told that the fuses were produced overseas and that there were no parts available for the car and no estimated date when the parts would become available. The service representative at the dealership informed me that GMC had sent out a flyer relating to this problem and that it was a known problem. After 3 weeks I was told the car was repaired and I picked it up. Three days after picking up the car I had the same problem. The car was towed back to the same dealership. A GMC field technician was dispatched to the dealership to run diagnostics on the car. GMC is in the process of re-purchasing the vehicle from me under the California lemon law. The car has been at the dealership for repair of this problem for 7 weeks.

2017 Chevrolet Volt extreme engine hazard: On 22-Mar-2016 I purchased a 2017 Chevrolet Volt premier, all safety options. Driving on freeway at 65 mph, straight driving, relatively light traffic, the engine light came on yellow and steady (emissions system service warning) but the car uncontrollably decelerated. The freeway had no shoulder due to construction. The car smelled of burning electrical insulation confirmed by the tow truck driver. The car, with less than 150 total miles, in clear weather, at twilight, 76 degrees, California at sea level, straightaway, had a sudden and near total loss of all propulsion. This caused a lack of control (obviously) in the forward direction, causing an extreme hazard on the freeway. I am an experienced driver: Make no mistake, this was a serious manufacture's error. I checked, no parking brake, the car was in drive gear, I had both electric range and over 7/8 tank of gas showing a gas range of 360 miles - and I had just driven 60 miles. There was no brake smell, as I did not need to apply the brake because the engine gave no propulsion. My hand was off the regen switch. The car had a major malfunction causing an extreme hazard, and based on the smell, possible fire hazard.
