My Chevy Volt was at a car wash and the attendant was able to turn the car off while still in "D" gear. The car is able to roll and move while in this gear. I was surprised so I tested it for myself, and sure enough you're able to turn the power off and exit the vehicle while still in 'd'. every car I've owned (automatic) forces you to shift into P or N before allowing the key to remove. This is a great concern for me, so I called my Volt advisor today and was informed that other customers rolled into their garage, and the behavior was by design and normal.

This is the second Volt I owned in a year that exhibited this issue. Upon braking and passive deceleration the car makes a loud audible whining noise coming from the engine compartment. The dealer states it is a regenerative brake bearing failure. This issue is related to the bearing cage failing causing the bearing to lose its integrity.

I leased a new 2013 Volt on Friday and drove it to work and home on Monday. The battery display showed it was at minimum, zero miles remaining. The Volt was running with the internal combustion engine. As I pulled out of a parking lot, "'propulsion power is reduced"', "'engine not available"', and "service stabilitrac" displayed on the driver information center. After going about 500 feet, I stopped at an intersection to make a left turn and the Volt stalled. I turned on the flashers and attempted to restore power by pressing the brake and the power button. The displays lit up but the instrument cluster continued to display "'initializing-wait to shift"'. I turned the Volt off by pressing the power button again and attempted to restore power several times with the same result. Cars behind me were attempting to pull around on the left side but were blocked by cars turning onto the two-lane street. I pushed the on-star button and requested assistance. Soon, a Volt specialist came on the line and said she suspected the security system or the 12V battery. She had me turn everything off and walk 200 feet from the car. When I returned and tried to start the Volt, it started briefly but shut down. She said the 12V battery might be low and they would have the tow truck driver bring booster cables to charge the battery. I had managed to push the Volt to the curb and got some cables to boost it. The Volt initialized and the displays looked normal. I drove to the next intersection and stopped for the light. When the light changed, it stalled again. I was able to continue to my house on battery power but it would not go up the slope of the driveway. I tried to charge it but the charge cycle would not start. The next morning, it had "'plug in to charge" light on. I started the charge cycle. It goes to the dealer tonight.
