2016 Chevrolet Volt transmission complaints
Page 2 of 3: complaints 11 to 40 of 51, newest first, as owners wrote them.
GM issued a special coverage warranty for 2016-2018 Chevrolet Volts that had a BECM failure. However, they did not include all of the Volts. We have a 2016 that has a catastrophic BECM failure. The car won't start and the only indicator was the day before it said the vehicle didn't charge. This appears to be the same issue, but Chevrolet did not include our model. We have about 87k miles and are only 3 weeks past the original warranty.
Vehicle suddenly lost power and displayed shift to park on display. Vehicle will not respond or display any status other than shift to park. Vehicle towed to dealership. Diagnosis of their mechanic is failed BECM module. Vehicle was brought to dealership 3yrs ago with infotainment center problems. Infotainment Software was updated but problem persisted. 2 years ago it was brought to dealership with complaint of intermittent inability to charge propulsion battery. Sunshine Chevrolet stated their mechanic could not diagnose issue so it was not covered under warranty. I demonstrated intermittent charging issue by plugging vehicle into dealership charger in front of showroom. I was at that time allowed to leave without paying diagnostic charge. 1½ years ago while car was still under warranty car failed to start. Called dealership. They stated it could be 12volt battery. I purchased and replaced battery at dealership. Car started but intermittent charging issue and intermittent infotainment issue continued. GM is refusing to cover BECM replacement saying Car is now out of 8yr warranty time frame.
I picked up my vehicle from Wasler Polar Chevrolet on 7/26/2023 after they claimed to have "repaired" my vehicle. After receiving my vehicle, about 5 miles away from the dealership, my vehicle suddenly quit keeping up with traffic, and lost *all* power equipment. Brakes, steering and acceleration were all unresponsive. The vehicle almost sent me under a semi-trailer, but I quickly forced the steering wheel to the left and engaged the emergency brake, which successfully stopped the car. The vehicle bricked itself, and had to be towed back to the dealership.
While driving suddenly the battery power died (1/3 battery life left) and the ICE came on reving very high and check engine lights came on and vehicle slowed. Pulled over at first spot I could find and tired to restart the car. Car would not power down or restart the ice motor and the electric drive motors stopped working and vehicle would roll backwards once put into drive. Vehicle had to be towed back to dealership. Car would not power down or reset.
I had just left my house about to enter the on-ramp to Interstate 95 south when my 2016 Volt abruptly and without warning stopped. I was unable to coast or pull the car to the side of the road. I was in the middle of the lane in a dangerous place to stop a car and a dangerous place to get out of the car due to the steady traffic entering the interstate. My car would not restart and I had it towed to the Portsmouth NH Chevy dealer. As it was the beginning of the GM strike I had to wait several days for the replacement battery control sensor then I had to wait for another 4 weeks or so for a replacement transmission to be installed. The day after I got my car back, about 2 weeks ago, the transmission fluid was leaking onto the garage floor. The Chevy dealer has ordered new transmission hoses but only one has come in and I was told not to drive my car until these were replaced. The sensor pad and transmission were covered under warranty, I was told the hoses to the transmission and labor to install them are not part of the transmission and not covered. The incident has been extremely inconvenient but the way my car just abruptly stopped and wouldn’t restart was very unnerving and could have been very dangerous. I do not have paperwork at the moment but can provide a dealer invoice of the covered work so far. Please contact me with any questions.
Driving 72mph down I5 interstate the display notified me with a check engine light with two errors, enigne propulsion reduced and engine overheating. I pulled over to the side of the road and called a tow. This was a very traumatic event. I had my partner and my 2 year old daughter in the car.I just purchased this used vehicle from a Toyota dealer the same day. It has 63k miles on it and still under powertrain warranty. I literally drove the car 45 miles. TOTAL. I have spent more time towing and fixing this car than actually driving it. This is a total lemon. I need a refund from GM and all the pain and suffering that this caused my family.
My car, without warning, lost power while driving and then flashed an engine light. This happened on a street and I was able to coast to safety, but if it had happened in an intersection I would not have been so lucky. The problem was confirmed by a dealer as a failure of the Battery Energy Control Module, which has been happening to this car with numerous other owners, according to the Volt owner website.
When attempting to power down the car, a message, “Action required, Shift to Park” appears and car will not power down. After repeated attempts, sometimes requiring 10 or more, by re-starting the car and attempting to power down, it has eventually powered down. This problem is intermittent and the car WILL power down successfully repeated times, and then do it’s “shift to park” refusal to power down. There are hundreds of complaints on the GM Volt owners’ forum and even a Technical Service Bulletin No. 19-NA-206 dated February 2020 (maybe even more recent, but that’s the latest one I know of). The service bulletin also includes the Chevy Blazer, Malibu, Traverse and GMC Acadia (which, I understand, there is now a class action suit in that regard). If the car will not power down, it could drain the battery and leave the driver stranded, as well as making the car unable to be locked, which could also be a safety issue.
Action Required Shift to Park message comes up on the dash after starting the vehicle & shifting into gear out of Park. The message goes away when shifted back into Park, but the vehicle doesn't respond when shifted into gear. Reverse, Neutral, Drive, Low - none will engage. I had to repeat the process of starting the vehicle 28 times before it would operate as it should. Start Vehicle to View Application message comes up when in Park & trying to shut the vehicle off & will not power down until the driver door is opened. I worried that I'd be stranded if this continued to happen & took the vehicle to Brad Deery Motors in Maquoketa, IA for repair on 4/14/22. I paid $736.71 & the invoice states: 106128 shift to park, diag, intermittent open in the shift park solenoid, replaced shift park solenoid and jumper harness, tested working properly. I brought the vehicle home & had the same messages appear on 4/19/22. I have since read a forum on the Volt & understand that this has been a common issue & found a service bulletin: 19-NA-206, but wondering if there is an actual recall. I plan to contact GM regarding this issue.

There is a “Shift to park” message on the driver information screen when attempting to shut off vehicle. I don’t know if the vehicle is still in gear and will move (forward or back) when I think it is in Park. I have not had it in for inspection/repair yet, as it is a recent occurrence that is becoming increasingly frequent. This started happening around 11/15/2021.
When parking vehicle a "Shift To Park" error appears on the dash and vehicle will not turn off for some time. This is an intermittent issue that seems to be getting more frequent as time goes on. Vehicle can be stolen if issue is unnoticed.
My 2016 Chevy Volt has an issue where the is an intermittent shift to park message displayed while the vehicle in in park. This issue has been identified as a widespread issue and Chevrolet has published a Service Bulletin (the federal safety agency Technical Service Bulletin 19-NA-206). The most recent version is Version 6 that was published in December 2020. The dealership is refusing to perform repairs that are clearly under warranty. The service bulletin specifically says it is covered under the warranty.
Vehicle Shifter does not correctly register the vehicle is in park. Does not allow the vehicle to be turned off. This is a common issue experienced by Gen2 Volt owners and well known by GM Service Tech and GM has not yet issued a recall. There is a potential safety issue if someone believes the vehicle is parked and exits the vehcile and the car is left running. Potential Driver Confusion on the park status could lead to the vehicle continuing to run or being put back in gear. GM needs to issue a recall for Gen2 Volts - 2016 and on.
When I put the car in park and try to turn it off, I frequently get an error on the gauge display that says "action required, shift to park." this is very frustrating. When this error happens, I'm unable to power off the car or lock the doors. I turn the car back on, jiggle the shifter or move it into drive and back to park, and then try turning the car off again. Sometimes I have to go through this process 5 or more times before the car will power down. This error happens about half the time that I use my car, which makes it a daily problem. I bought the car used in oct 2019, and the previous owner also had the problem but I don't know when it started for him.
An error appears "shift to park" when parking. The car does not recognize that it is shifted to park thus it continues to run. A running vehicle that cannot be turned off and can run on gas is a considerable hazard. The gm forum for volts contains many such messages for 2016 volts and a problem with the same system error LED to a recall in 2017 volts. The problem is occurring with increasing frequency in this car, starting a few months ago.
When parking the car there's a chance for the error "shift to park" to occur when trying to turn off the car,. This is due to a defective switch that wears out within the shifter assembly. The error starts to become more and more common as time go on. It is too easy to accidentally leave the car "on" when shifting the car to park and stepping out of the car and using the push to stop. The only known workaround is to flick the shifter button until the car registers that the car is now shifted to park. This is a recurring and well known issue in the chevy volt community. It's predicted that all 2016+ chevy volts will eventually develop this issue due to the defective design of this switch. I have another volt in the family that's already had the shifter replaced because of this same issue.
After 100k miles right when my warranty ends, I'm getting the shift to park error message, constantly having to power up the vehicle off and on is annoying. I I feel like the car is breaking more. Very unsafe.
After putting the shift lever in park, then powering the vehicle off the dashboard would advise to shift the vehicle in park. Could not lock vehicle, lights would remain on. This could be worked around by pressing the shifter knob a few times to clear the message. Brought vehicle in for regular service, was advised there was a short in the wiring harness related to the shifter knob. Harness was replaced, issue has not repeated. It has been noted online that this is a common issue with generation 2 volts, I wanted to add my vehicle to the list of those affected.
When putting shifter to park, the action required messages is shown as: 'shift to park' issue. The car will effectively not turn off. You'll be unable to lock the car and the lights will stay on for a few minutes. Worse yet, it is intermittent although it generally gets worse over time.
The vehicle does not recognize it has been shifted into park, which does not allow the vehicle to be turned off. Dash display states 'action required, shift to park'. This happens consistently and is a known issue by chevrolet. Yet they have not issued any recall. It is known as the 'shift to park' issue. There is no work-around for the issue other than shifting back and forth into gears, sometimes hundreds of times, before the error clears. For example: my wife took my daughter to an emergency room and could not get the vehicle to turn off. She tried to clear the error a few times before having to leave the vehicle running in the parking lot.
Keep getting action required message "shift to park" even though the car has been powered off. It takes about 5 trys now to actually power off the car, have to repeatedly turn the car on and off to actually power off the vehicle.
While turning off vehicle: vehicle is shifted to park ignition button is pressed message appears on console 'action required: shift to park' vehicle will not turn off with prndl in park position
System does not recognize when gear is in park (p) - the prompt on the screen states "action required: shift to park" (see attached screenshot) even when the gear is already on park (p) - the work-around is shifting the gear from park (p) then l then back to park - sometimes you have to do this several times.
Unable to turn off car when shifter is physically shift to park, but dash warning has a "shift to park" warning. Back in dec 26 I bought the car in for the same issue and the shifter cable was replaced. But shift to park warning returned a few months later. It is a matter of time before this issue will return .
Shift to park issue. When trying to turn off the car you put in park and press on/off button. Car says you need to shift into park even though you have shifted into park and is so indicated on the dash. You have to shift the shifter and turn on and off until finally turns off. Crazy and a know problem. Dangerous and need a recall.
Car says "shift to park" at random, when car is already in park. Prevents you from powering off the vehicle, and have to sometimes wiggle the shifter before it will detect it is actually in park.
Various times when putting the car into park and then turning off the car the message stating action required: shift to park will show on the console screen. The car will not turn off until the car recognizes the gear is in the park position, which it already is. It takes some shaking of the shift button to get the car to register that the gear is in the park position. It used to happen maybe once a month but now it seems to happen a few times each week.
2016 gen 2 chevy volt experiencing error message of 'shift to park' even though car is in park. Car will not turn off until message cleared and that takes several attempts. Issue is widespread based on internet search. Also, transmission cooling fluid leak from transmission coolant intake line requiring complete replacement.
