It is very difficult to shift into park. Nearly have to push hard to have the park setting engage. Unable to turn engine off when this happens. Also, the window will not go up smoothly. It goes up and down all on its own. It appears to have a mind of its own. You must open the window all the way before it will close. Cannot preform that function when it is only partially opened.

I am having a 'shift to park' issue. When I stop the car and shift to park, I attempt to power off the car. The Volt will not power off and I get an alert on the dashboard that states "shift car to park to turn off". but the car is already in park. I am unable to lock the car and the lights will stay on for a few minutes. Worse yet, it is intermittent. After multiple attempts at re-starting and stopping the car if usually turns off. My Volt has only 28K miles.

My wife and I were taking a 200 mile trip. I was using the "hold" mode, driving at 65 mph, and about 60 miles into the trip a message came up that I was in reduced power mode and the check engine light came on. I pulled over and read the manual and then proceeded another 30 miles using the engine. I reduced my speed to 50 mph. After stopping for an hour at our destination, we started back home, but the same alerts were on the screen. I went to a local Chevrolet dealer, 5 miles. Before getting there the engine shut off. I had 40 miles of battery left so I proceeded the last 2 miles to the dealer on battery power. They could not service the vehicle so I had it towed by aaa 90 miles to tulsa. The day before I left I had received the monthly diagnostic report which stated all systems were fine. The car has 27,000 miles on it. The dealer says it is the egr valve, which are back ordered. I don't know when it will be repaired.

Prior to starting my 1,100 mi trip with my 2017 Volt premier, I inflated the tires, checked fluids, & charged the car. The monthly diagnostic report I received the day before my departure indicated no problems with the car, which had approx 40,500 mi. I was driving on interstates & highways using hold (gas) mode, occasionally mountain mode. Approximately 275 mi. Into the trip I received power propulsion reduced alert. After an additional 50-75 mi I received an action required: Engine overheating reduce speed alert. I exited the interstate and proceeded to the nearest dealership to determine if it was safe to continue on my trip. I was told that the propulsion alert was not an immediate concern & that the overheating was likely not related. I also received a GM diagnostic E-mail stating there was an emissions problem that should be serviced within 7 days, but did not become aware of this E-mail until a day later. Approx 200 mi later, I was on a remote, unlighted highway when I received an engine unavailable alert and lost power. My car quickly decelerated, but I was able to get to a narrow shoulder. I tired to put the car in park, apply emergency brakes, and shut the car down but it was difficult to tell if these features were working. I put the hazard lights on and waited for a chp officer due to lack of cell service & highway safety concerns at night. After 3 hours, all systems failed, including lights. Only manual locks worked. After two 30 mi tows to get to a dealership with a Volt tech, it was determined that a bad egr valve was causing a fuse to blow, . the valve was ordered (tech remarked that the part is "popular") & installed. The issue seems to be fixed. But, it is unclear if this is a design flaw, manufacturing flaw, or a one time occurrence.

With increasing frequency, when I shift to park and turn the car off it does not always recognize that it is in park and directs "shift to park, " despite the shifter being in park, and will not completely shut down. This could be a safety issue, because it is unclear whether the car is in park or not. Also being unable to lock the car means the car is at risk for vandalism and/or a child getting into the car and turning it on.

Intermittent "shift to park" during parking process. This prevents vehicle from being turned off. Had the car into the dealer about a year ago to fix and the dealer was unable to duplicate. The problem seems to be worse when it is cold and it happens more often. Multiple actuation of the shift release button eventually causes the system to since the shift lever is in the park position. The date below indicates the last time it happened, but since owning the car, it's happened at least 5 times a month with this last week being at least once daily.

Upon starting the car (after sitting in the sun with windows up, so hot cabin), when I shift to any gear out of park, I get an action required shift to park message. The shifter will go to drive, for example, but pressing the gas pedal does not move the car, and I have the message to shift to park. This has happened twice. Both times I rolled down windows, and tried turning the car off and back on again to resolve this. After several rounds of this, the car did shift to drive and would go. However the engine is running (rather than only electric, as I usually operate); the battery gage in classical mode shows a rapidly decreasing charge, then increasing, then decreasing - also the place where it shows how many miles left in battery is greyed out at 0, even though the battery may appear to be charged more than half. Also, when trying to shift modes, hold mode is grayed out and I cannot activate it. Once I arrive at my destination and turn the car off, plug it in, next time it turns on as normal. Check engine light is on for all this, and does not turn off when restarting a fully charged battery the next day.

Purchased a 2107 Volt premier with 40K miles in July 2020. My wife was driving the car and it lost power on the freeway with a "shift to park" warning and check engine light. She was able to glide over to the shoulder and I came to rescue her. After repeated on off cycles I got the car to move a couple of miles with several "jerking" motions while driving then it died again and I lost power braking (went to manual only). This time I was unable to "re-boot it" and had onstar have it towed to a local Chevy dealer who has a "certified ev specialist"
