2017 CHEVROLET VOLT Complaints

My 2017 Volt reported a "Propulsion Power is Reduced" message on the display. When I took the car to the dealership for service, they stated that a new EGR valve was needed. The part alone is $1847. The total service with labor would have been over $3000. Looking online, it is a very common issue for the gen 2 Volts. Unfortunately, the dealership is saying this repair is not covered under warranty.

More than two weeks ago, my 2017 Chevrolet Volt LT showed BECM codes. The local dealership service center said they would order the parts for a complete replacement. The work and parts are covered under warranty as this has been a common issue. The BECM and coolant arrived within a few days, but the remaining parts are back ordered! After two weeks of waiting GM has failed to send the parts and I and my family are in need of our vehicle for both work and safety reasons. The part number for the parts that still need to be sent is: 11517042. The warranty coverage number from Chevrolet's bulletin in regards to this failure is: N232432680.

There is a part that fails on a lot of GM vehicles due to getting clogged (an EGR valve). It prevents the vehicle from reaching high speeds on the highway and can fail while driving (which happened to me). I could have lost control of the vehicle on the highway and crashed or gotten rear-ended. GM refuses to pay for repairs involving this part despite so many people reporting the issue that they needed to do another production run of the part after discontinuing it. Here are many others that experienced this problem: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Chevrolet Volt. The contact stated while the vehicle was parked, the message "Shift to park" was displayed, and the vehicle failed to turn off. The vehicle was taken to the dealer, where it was diagnosed that the gear shifter had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 81,000.

Shifter malfunctions when shifted to PARK. Car does not recognize shifted to PARK and error message appears on dash. States, SHIFT TO PARK. Will not fully shut off vehicle.

There was a recall for the HPCM2 where the propulsion power reduced warning would come on whenever the car's cell battery was depleted. This happened with my car and there were several times it slowed on the freeway and on exit ramps as I tried to safely get my car off the road. It first happened on 4/13/25. I took my car to a regular mechanic who charged me 3k of repairs on basic maintenance, new tires, etc but were unable to fix this issue. They advised it was a manufacturer issue and to go to a hybrid specialist or a dealership. I called a hybrid specialist who found the faulty code and advised the same. I took my car to Felix Chevrolet (3330 S. Figueroa St. LA, CA 90007) and they offered to do many maintenance service items that I had done earlier this week in an attempt to fix the HPCM2 software bug. After I told them that the maintenance items were complete, they called me back an hour later to tell me I needed other maintenance repairs that are less common. When I gave them the description of the recall and re-explained this is identical to my car's symptoms and that this manufacturing issue may have affected other vehicles like mine that were outside of the recall batch, they told me it was impossible to apply this diagnosis as long as my VIN number was outside of the recall batch. Can you please add my VIN to this recall or have my car reviewed by someone who can debug the software?

P0401 code caused the car to say “propulsion power is reduced”. I was on the highway and had to pull off to find a safe place.

Unknown My car has been accelerating and decelerating on it’s own while I’m driving.I got it checked with Fix Finder and states that my EGR Valve and ABS System failed. I brought it to a mechanic for a repair and I was told that the valve was unplugged so they plugged it back in and cleaned it , and said that everything was fine it said it might also be the cause of the failed ABS System but everything looks fine. After I got it fixed, it’s doing the same again and it’s worse this time. The car is accelerating on it’s own faster than what it did but the dashboard is saying 0mph. I was driving in the highway when it happened and it’s scary so I had to pull over.

I am submitting this complaint regarding a recurring and potentially hazardous issue in my Chevrolet Volt 2017.The vehicle frequently displays a “Shift to Park” warning message even when the gear shifter is correctly in the Park position. This malfunction prevents the car from shutting off properly, posing both safety and operational concerns. This issue is widely reported among Chevrolet Volt owners, and General Motors has acknowledged it in Technical Service Bulletin (TSB 19-NA-206). Despite this, no formal recall has been issued to ensure a permanent solution for affected drivers. My Volt currently has 138000miles, and although it is outside of the Voltec Warranty period, this is clearly a manufacturer defect—not a result of normal wear and tear. The problem affects the safe operation of the vehicle and may lead to battery drain, inability to power down the car, and driver confusion. I strongly urge the National Highway Traffic Safety Administration (NHTSA) to investigate this issue and consider initiating a recall to protect drivers and ensure accountability. Thank you for your time and attention to this matter.

Battery Energy Control Module Failure There is an existing NTHSB issue related: N232432680 I was told my VIN is not included in this issue, so the failure is not covered under warranty by GM. That said, the same failure and symptoms occurred (prompt multiple battery cell failures leading to electric drive inoperable). I was told, by others with Volt's who had same issue, that my VIN was not included because it was under a PZEV warranty since it was originally sold in California. I do not live in California, so the extended 150K mile / 15 year warranty does not apply to me. Car is currently at the dealership, and I was told the same repairs as in this NTHSB issue are needed at a price of > $2,500. As such, I am asking to have my VIN added to this issue for reimbursement.
