After you power off my car, I'll get an alert on my dashboard that says, " action required shift to park" the car will effectively not turn off. I'll be unable to lock the car and the lights will stay on for a few minutes. Worse yet, it is intermittent.

Becm failure at 32,000 miles. Car would not charge and would report ev range as 0 when it in fact did have range. The car also would not move/start reliably leaving the change of being stranded somewhere because of the faulty computer. The dealer tried to fix the software on the becm but it ended up being a failed becm. It seems very common for this to fail from what I have read online. The dealer fixed the issue under the voltec warranty and I have not had an issue in 4+ months. There was obviously a bad batch or engineering defect on the stock becm.

The contact owns a 2017 Chevrolet Volt. While driving approximately 25 mph, the check engine indicator illuminated. The contact stated that the gas engine turned on while there was a significant amount of battery range left. As a result, the contact had to coast the vehicle downhill to the side of the road. The contact attempted to place the gear into drive; however, the gear shifter did not recognize that the vehicle was in drive. Instead, the gear shifter indicated that the vehicle was in the park position. The vehicle failed to move forward or in reverse. The contact was unable to drive the vehicle. The vehicle was towed to allen gwynn Chevrolet (located at 1400 S brand blvd, glendale, ca 91205, 818-528-8597) where it was diagnosed that the gear shifter needed to be replaced; however, the repair was no longer covered under warranty. The vehicle was not repaired. The manufacturer was made aware of the failures and opened a case. The approximate failure mileage was 35,066.

When I attempted to turn off the vehicle, with the shift set to "P", I get a message that appears, "action required shift to park", and the vehicle will not turn off. I would have to turn the car on and off several times, sometimes roughly 6-7 times and sometimes I would have to move the shifter back and forth between D, N, R, etc. I had my local dealership (van GMC/Chevrolet) and they replaced the shifter harness which was a known issue. My Volt is continuing to flash the 'action required/shift to park' message and hesitates to turn off and then powers down.

Shift-to-park alert after you power down car. Effectlvely, the car won't turn off. Brought to GM in 2018 and they replaced the shifter. 18 months later, the problem has returned. Appears to be a chronic defect in the 2nd gen Volt.

On my 2nd day of ownership when the vehicle had 50 miles on it the vehicle stopped without warning in the middle of the highway. While driving 65 mph on interstate 5 (4 lane highway) the vehicle began smoking and lost all propulsion and forward power. The vehicle had just changed from electric power to gas power. The warning message displayed was "action required - shift to park". the orange engine symbol was displayed. Then the steering wheel locked up, all displays and controls were turned off. Luckily I was able to move from the 2nd to far right lane of 4 and get just off the highway. There was just enough space to glide the vehicle to a stop off the highway. However, the I5 is the primary trucking route and in this uphill location all semi trucks are required to drive in the far right lane. My vehicle was swayed continuously by the large high profile vehicles for over 2 hours. A chp stayed with me with flashing lights to attempt to move vehicles to the left. The vehicle was towed to the nearest dealership. The vehicle was replaced by the dealership with another vehicle after 9 hours. However, I am now in arbitration with GM over the same issue "action required - shift to park" with the 2nd vehicle. The vehicle has been in service for 95 days over an 8 month period and I am seeking a vehicle buyback under the California lemon law with the BBB for impairment of value, use, and safely.

The "shift to park" message is displayed when the vehicle is stationary and already in park. The vehicle will not turn off if it believes it to be in any other gear other than park. The vehicle was serviced at my local Chevy dealership and the shifter control and transmission controls were replaced. The vehicle was out of service for 18 days and road tested for over 250 miles by the technicians. The vehicle is unsafe and unreliable. I am in arbitration with GM under the California lemon law and am requesting a vehicle buyback.

While entering the highway the vehicle experienced significant loss of propulsion and the warning displayed "propulsion power reduced".this loss of power occurred when the vehicle switched from electric to gas power. I have experienced issues with the vehicle switching from electric to gas regularly and it sputters and bucks. After a few miles the sputtering and rough change to gas will dissipate. On this occasion the power loss was significant and dangerous. I would not have had the power or propulsion to enter the highway. I was able to divert to city streets and get home at speeds under 40 mph. The vehicle would not go any faster. The vehicle was serviced by my local Chevy dealer and out of service for 18 days with approximately 250 miles of road testing while in service. I no longer believe this vehicle to be safe or reliable and am engaged in arbitration under the California lemon law and the BBB.

While driving on a busy surface street the vehicle lost all propulsion and stalled. Steering locked up, was disabled, and electric power stopped. The warning light read "action required - shift to park'. this stall is immediate and highly dangerous. I was able to glide to the side of the road without being in or causing an accident. The orange engine symbol was illuminated. All systems shut down on the vehicle. The car was towed to the nearest Chevy dealership but we were unable to turn off the vehicle or shift it in neutral. The car start button would not turn off the vehicle and had to be towed running and the battery disabled at the dealership.

The dealership tells me that without fixing this the vehicle may not turn off. Since it is a hybrid it may then turn on silently generating carbon monoxide. Recently when I stop and turn off the car via the dash push button sometimes(but not always) the console says "action required. Shift into park" even though the vehicle is already in park. It happens randomly, and does not seem to be related to whether the brake pedal is depressed, how long it has been in park, or how vigorously the lever was shifted to park. The dealer tells me that the part and repair are not covered under my warranty, or when the part would be available. Since I am aware of multiple deaths related to inability to turn off a car leading to carbon monoxide generation, I am concerned even though the manifestation I have seen is a spurious warning rather than a failure to turn off the car. Potentially the dealership is wrong. I cannot otherwise obtain accurate information about this problem, its solution and its consequences.

2017 Chevy Volt premium with 45,500 miles with full electrical charge and 3/4 tank of gas. On Friday, 08/09/2019 I attempted to move vehicle in driveway in a, M, hours. Vehicle had difficulty shifting from park into reverse. Message wait to shift had cleared from instrument display. After shifting and no response in propulsion, display showed "shift to park and depress brake" after many attempts to repeats the process. Turning off the engine and re-starting I was finally able to drive the car. No other problems displayed or encounter during remained of morning. Vehicle started and shifted as expected. In the afternoon my wife encounter the same problem and could not get the vehicle into gear nor shut it off to attempt to restart. After 30 minutes and multiple cell phone calls and my searching the internet she was finally able to get the car into reverse and drive correctly as displayed in the stick shift. I scheduled an appointment at the local Chevy dealership for earliest appoint a week away. The vehicle was parked and prepared for the hook in the driveway. On Monday 08/12/2019 I was able to get the vehicle in drive after multiple attempts to get it out of park. I drove the vehicle to the dealership rather than wait to for more unexpected problems and possible having it towed on Friday 08/16/2019. Dealership. On Tuesday, 08/20/2019 dealership notified me they had diagnosed the problem related to the exhaust emissions module and that effected the shifting problem. They replaced the part. The cost were covered my extended warranty. On Thursday 08/22/2019 I retrieved the car. We have not experienced the problem since. Safety issues are as mentioned above. There has been no recall by GM / Chevy for this issue.

Switching from electric to gas motor while driving approximately 60 miles per hour, total loss of power. Dashboard indicator says to place in park. When stationary, unable to turn vehicle off. Repeat start button and shifting, unable to disengage engine to reset and restart engine. Had to tow vehicle. Chevy technician necessary to disengage/turn off vehicle. Restarted with gas. Loss of power when vehicle switches from electric to gas happens often. General Motors/ Chevy is unable to fix. Vechicle only has 7500 miles. Had a complete swap of transmission with only 5 miles on the vehicle, the first time this happened. Complete loss of power on highway is a huge safety issue. Unreliable vehicle beyond 40 miles on electric battery. 4 times in less than 2 years complete loss of power. 3 times on highway, once city street. Towed twice. Twice I was able to turn off the vehicle and restart with the gas motor. The other 2 times I was not able to turn off the vehicle and was unable to regain power; had to be towed to nearest dealership where the technician specialist was required to disengage and restart the vehicle with the gas motor ( at this point there was no more power in the battery).

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)!!

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.

While driving my 3 year old son to school my Volt lost propulsion while slowing down for a red light. The car displayed a "loss of propulsion" warning and within 3 seconds my car had no power and was dead in the road. The Volt is a hybrid and it lost propulsion while in electric mode. After the car stopped I tried turning it off and on and I tried to force it to run in gas engine mode but nothing worked. My car was towed to a Chevy dealership where it took 31 days to diagnose and repair. GM was called in to help diagnose the problem and they told the dealership to replace the entire transmission. In the Volt the transmission also contains two drive motors.

NHTSA id number: 10113301: While driving 1 month old car with 1000 miles on freeway, car suddenly stalled. This created a dangerous situation as I was almost rear-ended and had to cross several lanes of traffic with no propulsion. GM acknowledged this as an issue in January 2017 and again in October 2017 with revised NHTSA id number: 10123263. Why is GM allowed to continue to sell these vehicles with such a dangerous issue without repairing them prior to selling to an unknowing consumer? they committed fraud, negligence, and misrepresented their product when knowingly sold a defective product. The dealer refuses to take the vehicle back and to refund any money paid.

The car will go backwards while in park, specially when the battery is depleted. Late at night I had parked the car in the middle of the street got out and was going to move a trash can out of the way when the car started rolling backwards. I tried to stop it but could not so I had to jump in and put on the brakes just in time before it hit the neighbors car. I got a bruise on my knee trying to get in to the car. I was able to repeat the problem and video tape it as proof. GM engineering had someone come out from raytheon and check out the car and he along with the mechanic at moss brothers Chevy confirmed the problem. They said they could not repair the problem, and they wanted the car back at GM to run further tests on it. They offered to replace the car but I was not satisfied with the price difference I had to pay for the replacement. They had to deliver the car on a tow truck because it was deemed too dangerous to drive. They told me they will not repair it under warranty the service manager said he could not touch it at GM order. I am still trying to figure out a way to replace the car because it is unpredictable how the park and reverse gears will act I have many examples of the problem on youtube and on one occasion the car would not go backwards in reveres and after a few minutes it suddenly jerked backwards at high speed scaring me and my family. Here is the link I provided to GM before they took the car in. Https://www.youtube.com/playlist?list=pl7etugmnbo_7jqp6qevydskwi7ooqf5_D I don't want someone to die like the star trek actor who got pined by his car. All this happened a few days after I had purchased the card. The dealership held my car for 30 days before they returned it to me. They did give me a loaner for the 30 days.
