When vehicle runs out of gas and only has battery power (no matter the charge) the car goes into reduced power mode which is dangerous in any traffic especially interstate highways!!! this happens every time you run of gas!! also the adaptive cruise not working all the time and disengages by its self for no reason(like nothing in front of you)!!

Like others, including the incident in rancho cucomonga, ca on the same day, April 25th, I was driving on the highway at high speed. I was in the carpool lane on the 210 freeway. I think I also was told to put the car in park. I lost the ability to accelerate on at a very dangerous time, while I was the furthest to the left in the late afternoon. Miraculously, there was only 1 car quite far behind me. So, after deceleration was forced upon my car, I began to steer the car to the right through 5 lanes - one of the widest parts of the highway at that point. Here is what I now think. I have been through loss of power in my 2014 Volt. I had accidentally turned it off while being on the highway. They fixed that design flaw in this 2017 model. I have shared my theory with GM. GM/Chevy has 3-way called me with the "stolen vehicles dept". they aggressively describe how they won't issue a slow-down through the on-star unless they have a request through police, the police are behind, the lights blink, etc. But, they're reluctant to share what happens next. They've been reluctant to share how they track your vehicle through the VIN and gps tracking. They're reluctant to share that this system can be hacked. It is evident that much can go wrong once the ability to control your car is placed in other's hands -- who aren't in the car driving it. The dealership could see the code of the slow-down. Of course they were surprised. This wasn't just a "failure". this is a "feature" in the car...but someone else used it without our permission. I want the on-star control disabled in my car!!! it could have killed my daughter and me. It could have killed the others who reported a similar situation.

Urgent urgent. This is something wrong with the 2017 Volt. My vehicle caught on fire while driving down the interstate at higher speeds. I have found two others that this has happened too. GM didn't even investigate before denying liability, they made a determination over photos. All 3 vehicles had over 20K miles on it. Others lives may be in danger. Please investigate.

I was driving on freeway at 65 mph then all the sudden I got check engine light one and message "action required, shift to park", I noticed the door unlocked by itself and the car starting to lose propulsion, I glided off the freeway and stopped at the end of off ramp due to red traffic light, then the car can not start again. After tow truck came, the car started again and I was able to drive to dealer for repair. Dealer found two error codes in the history P0ac4 and P0604. Although the car is working fine at this moment and seems like it was just some sort of computer crash, however it was very dangerous to lose propulsion on the freeway and stuck on a heavy traffic off ramp.

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.

Strong burning and/or fuel smell filled the passenger cabin. This has happened on several occasions most notably when the car was operating in 'engine running due to temperature' mode. The odor was strong enough to cause dizziness and required to the windows to be opened to vent the cabin. The smell and order now is persistent even when driving in all-electric mode. My intension is to replace the cabin air filter with a carbon air filter per 16-na-127.

My 2017 Chevy Volt suddenly lost all power while I was driving about 35 mph in electric mode. The car has been driven about 4500 miles. A "shift to park" message was displayed on the dashboard. I could not restart the car and had it towed to a dealer for service. The dealer replaced the power inverter module and updated the software. After the repairs, the electric motor has stalled on two occasions and the car shakes violently then switches into the gasoline engine mode.

On 3 separate occasion my car has died on the highway and lost acceleration, GM issued a recall between my first and second incidents and the recall fix did not fix the issue as this happened a third time. Nov 14th was the first time but it has happened multiple times. This is very dangerous and people will probably die because of this. The error message on the screen is propulsion power is reduced

We are writing to voice a very disconcerting and dangerous incident with our 2017 Chevy Volt. On a return trip at dark from cleveland, Ohio to rochester, NY on 12-26-16, our engine suddenly gave warning beeps which prompted my husband to pull over to the shoulder on interstate 90 in erie, pa. We had all of 15-20 seconds to get off this heavily trafficked highway when the car literally shut down.. nothing worked not even the warning flashers. We could not open the trunk, and had we not kept one door open we would not have been able to enter the car. In summary, the total failure we encountered shows the serious safety issue related to this car. We are now reluctant to take it on trips this incident could have resulted in a serious accident had we not been able to pull off onto the shoulder.

The vehicle center display does not work reliably. Most concerning to safety is the fact that this renders the reverse camera inoperable. Other things that don't work include bluetooth, radio, on star, controls for the vehicle setup and charging parameters, air conditioning, energy usage display, and so on. After several service visits and calls to GM, they determined that if you leave a phone plugged into the usb cord for the audio system, and power the car off without first unplugging the phone from the charger and even the charger cord from the usb port (with no phone plugged in) or else the next time you start the car the screen and functions on it will be inoperable until the car is powered off for several minutes. Whether or not I unplug my phone when I turn off the car should prevent the backup camera from functioning nor the details about electric car charge usage. GM has told me there is nothing more they can do, that's just how it works.

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. From dealer printout "internal transmission prime notor(sic) internal failure P03af drive motor remove and replace with srta srta unit".
