2019 CHEVROLET VOLT Power Train Problems

The contact owns a 2019 Chevrolet Volt. The contact stated that while the vehicle was shifted to park(P), the message to “Shift to Park” remained displayed. The contact was unable to turn off the vehicle. The contact stated that for approximately 10 minutes, the gear shifter was shifted out of and back into park to be able to turn off the vehicle. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 35,000.

When shifted into park, persistent error message that car was not in park. Unable to shut off the car despite numerous manipulations of shift. Few similar preceeding incidents were resolved by shift to drive then back to park. Goes to dealer tomorrow. Car running endlessly is dangerous. What if I could not stay with the car, or the car was on the local ferry. No one has inspected it yet. First time problem occured was in November 2024. Most recent more serious problem occured Friday. I am afraid to use the car since, and have not driven it since.

Two incidents related to the powertrain. 1) In December, 2023, the EV battery was drained and the car would not start based on the gas motor. The dealer fixed it in our recollection. 2) On [XXX], I was driving the car out of a Detroit Convention Center parking lot, going up the ramp when the car, with no warning, completely lost power and stopped. The message on the display said "Powertrain loss" or "Powertrain lost." I wish I had taken a photo of it, but I was panicked. Cars were backed up behind me on the ramp out of the parking garage, honking and having to back up. I tried turning the car off and on, googling the problem, and was about to call a tow truck when after 12-13 minutes, I was able to restart the car. I was scared that this could happen again on the freeway. When...

Mileage: 38523 Engine Not Available Service Soon Propulsion Power Is Reduced Fuel Range Low: 3/4 Tank full of gas [XXX] - I was driving Northbound on [XXX] South of Castlewood in Northern California. I was driving 70 mph when I suddenly received the error messages above on my dashboard screen. The vehicle immediately had power from 70 mph quickly going below 59 mph. The traffic was extremely high and I had to quickly use my hazard flashes and carefully maneuver to the right shoulder of the frwy. The vehicle lost power so quickly I could have easily been rear ended or in a serious vehicle accident. The dealer test drove the vehicle and stated they received the errors at 95 mph. The dealership is recommending I have the entire transmission replaced with the assembly and the 45,000 mile maintenance. No other warning lamps, messages or symptoms or failures occurred. First...

Vehicle lost propulsion and all power mid turn at approximately 45mph. Powe steering and assisted brakes were gone. Conditions were rainy, resulting in single car crash. Car did not restart. No codes present. Occurred again after repairs at 70mph on highway. Codes P0AC4 and P0C0E indicating Drive Motor Power Inverter B. Despite being under warranty, GM cannot repair, and has no replacement parts. GM has ignored messages requesting buyback per federal law.

When shifting to park, the vehicle reports that it is NOT in park. This prevents turning off the vehicle. It is difficult to confirm that the vehicle is indeed in the park mode. This is happening more and more frequently and we will contact the dealer for service. I have not called the dealer about this yet.

System propulsion lost on start up. When I called a tow truck for a jump, they confirmed the 12V battery still had a full charge and the vehicle should have been able to start. The dealer indicated that they saw the same propulsion system DTC, but could not identify the problem. After a few days of having it, the car worked "normally" again, and the dealer was unable to replicate it in the shop. This happened once before on start up - the vehicle spontaneously lost power and seemingly resolved itself a few days later.

HAD SHIFT TO PARK APPEAR AND CAR WOULD NOT SHUT OFF. IF YOU PLAY WITH IT IT MIGHT SHUT OFF BUT WILL NOT ALLOW IT TO RESTART. GM IS AWARE OF THIS AND HAS PUT MULTIPLE TSB'S OUT TO FIX IT AND NOW THEY HAVE A NEW ONE. IT AFFECTS ALL GEN 2 VOLTS AND OTHER MODELS. IT CAN STRAND YOU IF IT HAPPENS. THIS SHOULD BE A RECALL NO ONE WANTS TO BE STRANDED IN THE DARK ANYWHERE.

2018 CHEVROLET VOLT. CONSUMER WRITES IN REGARDS TO TRANSMISSION FAILURE. *LD THE CONSUMER STATED WHILE DRIVING THE FREEWAY, THE VEHICLE EXPERIENCED SUDDEN LOSS OF ACCELERATION. THE DEALER WAS MADE AWARE OF THE FAILURE. *JS

BRAND NEW CAR SUDDENLY STALLED WHILE DRIVING - STILL HAD ABOUT 10 EV MILES LEFT AND A FULL TANK OF GAS WHEN IT HAPPENED, TRAVELING STRAIGHT AT AROUND 45MPH. MESSAGES DISPLAYED ON DASH TELLING ME "PROPULSION POWER REDUCED TO 0" AND "SHIFT TO PARK", GIVING ME ABOUT 30 SECONDS TO PULL OVER BEFORE IT COMPLETELY STOPPED. RESTARTED CAR SEVERAL TIMES, BUT "INITIALIZING WAIT TO SHIFT" AND "PROPULSION POWER REDUCED" MESSAGES DISPLAYED, AS WELL AS CHECK ENGINE LIGHT. CAR WOULD NOT SHIFT OUT OF PARK, EVEN TO NEUTRAL. LUCKILY I WAS ON A QUIET CITY STREET AT NIGHT AND NOT ON THE FREEWAY, AS THIS COULD HAVE BEEN EXTREMELY DANGEROUS. ON STAR SERVICE HAD ME TOWED TO DEALERSHIP, WHOSE SERVICE DEPARTMENT SAID IT WAS A FAULTY PART IN THE ELECTRIC ENGINE CHARGING MODULE. THEY WILL REPLACE THE PART. HOWEVER, SINCE HAVING THIS ISSUE I HAVE READ OF COUNTLESS OTHER SIMILAR SITUATIONS...
