We've had a total of three Chevy Volts. Two have been great, but the 2017 Volt we got in February 2017 has been awful -- the car completely loses power without warning. It happens while driving, both on the freeway and surface streets. And just to clarify, I don't mean the car was out of electricity or out of gas (each time this happened, the car had both). We will be driving along when, out of the blue, the car simply just stops running, leaving us to do our best to get it out of the roadway without getting hit. The car (which only has about 1,000 miles on it) has been in the shop off and on for about a month now. We have been very disappointed by how both GM and the dealer have been handling the situation.

We bought a new 2017 Chevy Volt at the end of December 2016 and had our first issue in early February 2017. What happened that first time was on (2/3/2017) while driving through traffic the car without warning turned off the electric wheel motors and would not allow us to power the car properly to get the car to the berm. We were nearly were hit twice while trying to steer the car off of the interstate highway as it decelerated. The car was completely disabled an needed towed back to the dealership. After the dealership had the car for a week they returned it with the explanation that the car needed to do software updates and they were too large to do over the car's satellite system ' but they never gave us any indication of how we would have been informed of the need for such an update. We then had another near accident today (4/6/2017) on the same highway and we were nearly pushed up under a semi while trying to maneuver off of the highway at 75 miles an hour. Again, the car without warning shut off the electric wheel motors and warned us to 'put the car in park'. it happened in exactly the same way as in February but no warnings had been issued for our car and we almost had a horrible accident. My concern is for my family and colleagues safety at this point and I don't want anyone driving in this car. I hate to think of what would have happened today if my daughter, who is a brand new driver, would have had to deal with the same situation sandwiched in by two semi-trucks and with a car trying to pass on the shoulder around her ' it could have been far worse. I am in several Chevy Volt groups on facebook and people who loved the generation 1 of these cars are having major issues from battery packs dying, to drive train issues, to speed control problems and more where people are having major system pieces replaced 2-3 times in the first few months they own the cars.

Wife was driving to work when car (with ~2500 miles on it) just shut off, luckily on a side street after crossing a busy highway. I drove to meet her and called onstar. It was in the "shift to park" mode. They connected me with the Volt support team. They determined it had somehow got into service mode and they talked me though getting it out of that. I decided to take the car directly to the dealer. It seemed fine for a few miles but it started displaying reduced propulsion power and died again about 100yds away from the dealer, after I had just pulled onto a busy highway. I tried the technique to get it out of service mode, but it did not work this time and had to call for a tow (and police detail so I wouldn't get rear-ended). The dealer repaired the car and said the problem was a short in the battery cooling system/pump.

I was driving my 2 month old car with ~2300 miles on a busy highway at ~ 65 mph when suddenly the car loses power and the panel reads "shift to park". luckily, I was able to maneuver the car (steering was still in tact) with the remaining speed to the side of the highway. However, had the highway been busier or if I had been on the far left lane, I don't think I would have been able to make it and would have created a dangerous situation on the highway. On the Volt forum, others have also complained about this. The repair, though covered, took 3+ weeks at the dealership.
