The contact owns a 2018 Chevrolet Volt. The contact stated that after coming to a complete stop and shifting into park(P), the message "Shift to Park" was displayed.

The local dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was 25,000.
While driving my 2018 chevy volt I received a reduced propulsion error. I pulled over to assess and turn off the car and turn it back on only to find when I turned it back on I received an enginer failure error and the car would not drive forward or reverse. I had to have it towed to a Chevy dealership for evaluation. I understand from research and talking to service experts this is a common failure among the 2017 and 2018 Chevy volt and it is abhorrent that Chevy has not issued a recall on a common failure that compromises the safety of the driver and other drivers around them.
On Nov 21, 2022, after approximately of 10 minutes (5 miles of driving), while attempting to accelerate from a stop, the vehicle lost the ability to accelerate. The vehicle was in full EV mode in the middle of a busy intersection. The vehicle had a full charge (50+ EV range remaining or 100% total EV remaining). The driver attempted to press down more on the accelerator to no avail. After approximately 5-10 seconds, in the busy intersection, without the ability to make the vehicle accelerate, the driver noticed the vehicle jerk (which occurred 2-3 times) at which point the ICE turned on and provided power to the vehicle, allowing the driver to drive out of the intersection. After several minutes of driving, the driver noticed "Reduced propulsion warning" was noticed/illuminated in addition to "Check Engine Light". After this point, the driver noted that the propulsion felt approximately 20% of "normal propulsion". The driver was also concerned about the ability to drive up very small hills due to reduction of propulsion/power. Upon arrival at the destination (2-3 miles from incident), the vehicle was safely parked, the vehicle's codes were checked with an OBD2 code reader and 19 codes were noted. Given the manifestation and safety issue of the vehicle, the vehicle was towed to Quality Chevrolet in Escondido where it remains as of 1/10/23. The codes collected on 11/21/22 include the following: 1. P0A46, 2. P0AC4, 3. P1E00, 4. P1B0B, 5. P1B43, 6. P1E1E, 7. P0AC4, 8. P1E00, 9. P0A46, 10. P1AF0, 11. P1AF2, 12. P1B0B, 13. P1B43, 14. P1E1E, 15. P1E22, 16. P0A46, 17. P1B0B, 18. P1B43, 19. P1E1E. Per the OBD2 code reader, the primary code was P0A46 (Drive Motor 2 Position Sensor Performance). As of 1/9/23, the dealer has indicated that the primary problem is with the entire Transmission assembly which requires replacement. The replacement assembly is not in stock, is back-ordered and there is no ETA to receive the transmission assembly. The vehicle has 32243 miles on it.
Reduc d propulsion power warning while driving in EV mode. ICE started and was able to make it 1/2 mile home. Failure diagnosed to a faulty BECM. Has been at the dealer for 1 month today with no word on when the part or repair will be done.

The gear shifter for the Chevy Volt has an issue where it does not register in Park. I need to contantlty move through the gears to have it be in park.
Going 80 mph on the freeway with adaptive crusie control on, the car begins to jerk, and the rpm's shoot up and down. The adaptive cruise control disengages, the stabiltrack, abs, and engine light turned on and the car goes into limp mode. As I slow down, the speedometer keeps increasing up to 90. After, I inspected the driver wheel speed sensor and discovered that the sensor tip in the hub had been damaged. The anti-click washer had broken and began cutting the sensor until it failed.
When car is put into park, system does not show vehicle is in park and will not shut off. It takes multiple times of pushing the start button and moving the gear shift back and forth before the car finally realizes and confirms the vehicle is in park and will turn off.
When the Gear shift is placed into park and the power button to turn the car off is pushed, I get an alert that says -??Shift to Park-?? and cannot turn the car off. I have to attempt to turn the car off and on several times before I can actually turn the car off and leave it.
The car won't shut off and requires you to shift to park but it is shifted into park. After playing around with the shifter eventually it will allow you to shut it off.
After turning off the engine, the car will frequently raise an alert saying "Shift to Park", even though the lever is positioned correctly on "P" (park) and the light for "P" is lit up.
When shifting to Park, and switching the car off, the vehicle will not register as being IN -??Park-??-?? and Displays -??Shift To Park-?? and accompanying warning chime. Further, the car will not turn off.
When I stop and shift vehicle into park and try to turn off vehicle. The vehicle does not recognize the vehicle is in park and will stay running. This had happened numerous times and is ongoing. Have read there is even a class action suit because of this problem with numerous different gm vehicles. Why has a recall not been issued?
-??Shift to park-?? message appears when car is in park making it impossible to turn vehicle off. This is a documented issue going back to 2016 across other Chevy vehicles
When turning vehicle off, it will display a message "SHIFT TO PARK" even though shifter is in the park position, the vehicle will also remain on. Sometimes have to jiggle the gear shift or shift back into park a few times before the message goes away and am able to turn vehicle off. This is very dangerous as if it's left unnoticed in a garage the car can be left running potentially filling the house with fumes. Can also run out the battery and gas and leave you stranded if away from your home.
