I have a 2016 volt bought from NYC and I am the first owner currently residing in TX. My volt currently has mileage of 30,020 but this propulsion power will be reduce error has been shown since last 100 miles or so, my commune is usually under 5 miles a day so I rarely use gas however recently due to work I have to commune pretty far for a week and relied more on gas and this error popup during on of the commune. (It slowed my car down significantly while on highway and eventually stop with message on the console says engine offline) With the following error codes found: P0031 P0054 P0030 P0135 P0403 P0405 P0443 P0458 P0489 P0597 P0598 P06DA P06DB P0AC4 P0030 This car barely has much gas mileages as it was primarily on electric, but this failure on highway comes suddenly.

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.

1. an error appears "shift to park" when parking. The car does not recognize that it is shifted to park thus it continues to run even when positioned on park. A running vehicle that cannot be turned off and can run on gas is a considerable hazard. This is an extremely common issue with the 2016 Volt.

Get "shift to park" error when trying to shut off ignition. Shift lever is in park but not recognized by cars electronics or switches or? this prevents car from being shut off -this is more than just an irritant. When you are stopped somewhere and can't turn off your ignition, you are in a really serious predicament! GM has had this problem on many electronic hybrids since 2016 models and will not or cannot fix! one google of Chevy Volt "shift to park" will show hundreds of complaints (many to your dept.) and no help in forcing GM to resove problem !

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.

Getting the "action needed shift to park" warning intermittently when parked and attempting to turn off car to exit. Unable to shut down vehicle when occurs.

- Hebron, KY, USA

The vehicle issues a message to move the gear shifter into park (shift to park) message even when it is already in park. The vehicle will not engage nor will it enable the driver to turn the vehicle off which results in unsafe driving circumstances and strands the drive in untenable situations. This is known in social media as the "shift-to-park" problem with Volt and other GM vehicles while GM is hush-hush about the issue. There absolutely needs to be a recall issued for all affected vehicles as this is clearly a manufacturer design issue given all of the problems drivers are having. It starts as an intermittent problem and continues to get worse over time with out any warning.

- Saratoga, CA, USA

When the driver attempts to power down the car, the driver receives an error that the car must be shifted to park before turning off even though the car is in park. As a result the car may not be turned off. Repeated attempts and "playing" with the shifter may or may not resolve the problem.

My electric car would not turn off and I received the error message "action required: Shift to park" on the driver display. I would have to play with the gear selector multiple times sometimes it would take 20 minutes just to turn the vehicle off. Visiting other forums, this is a common issue as it is dangerous to be stranded not being able to turn off your car.

- Pasadena, CA, USA

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.

This is an update to my original complaint #:11299056 for un-commanded acceleration on 1/13/2020. The Chevy dealership worked with GM corporate engineers and were unable to duplicate the problem after several days. The returned the car and blamed it on the floor mat. This is not likely since the mat is a oem heavy rubber mat and the accelerator pedal does not rest on the floor board. Since the car was returned and driving for weeks, I noticed the battery range will not charge more than 49 miles of electrical charge when it often charged up into the 50-60 mile range prior to the incident. I've been driving the car in slower heavy traffic lately and this driving style often increases electric mileage range after a full nights charge. It will not do so anymore even though the economy management screen indicate maximum range economy of over 250 mpg. I'm a retired gas turbine mechanic and I know a problem when I experience one. I suspect that a battery cell may have had an uncontrolled discharge and is no longer able to accept a recharge. I have relayed this information to the dealer. No response yet.

The car shows a message on the instrument cluster that says shift to park even though the gear shift lever is already in park. This failure to detect when the gear shift lever is moved to park prevents the car from shutting off and locking. Sometimes continuously wiggling the gear shift and repeatedly shifting to other gear positions and back to park can sometimes get the vehicle to recognize it is in park. This situation occurs intermittently without a pattern. Very frustrating. And dangerous.

This vehicle has a shift to park message that been seen on many GM vehicles. Some of the owner sites I have been to say that this is covered under warranty. I have not been so lucky with GM. The dealer did cover 1 repair of this problem but now says I have to pay. The problem has returned and persists. A shift to park message is displayed on the dash after the car is in park and will not shutdown. I have attached all the documentation that I have.

Warning about airbag system not working correctly and told to bring car to dealer within 1 day. Car was in motion on city street with my son in front. I don't know exact parts but I brought it to Chevy and they refused to pay for fix (so the car is still there while I appeal). It was something about the system in the seat and possibly dash that controls the airbag.
