2017 CHEVROLET VOLT Complaints

The engine light starts blinking and telling me propulsion power reduced, and then I cannot use the cruise control after that turns on, and it starts losing power, driving on I 70 after work all of a sudden it turned on and wet from going 76 miles an hour to 52 on highway I 70 where the speed limit was 75. This problem was a recall problem which was fixed and now is happening again on the same part and having the same problems.

The contact owns a 2017 Chevrolet Volt D2. The contact stated that while attempting to turn the vehicle on the vehicle did not start. The contact stated that vehicle restarted after an hour. The contact stated the during the second occasion the vehicle did not restart. The vehicle was towed to a dealer where it was diagnosed that the Battery energy control module needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was approximately 75,000.

I am reporting a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my Chevy Volt's High Voltage battery charging only to 65% capacity despite indicating a full charge. Subsequently, on February 11th, 2024, the check engine light illuminated again, and on February 12th, 2024 and again on November 25th, 2025, while driving to work, both times I experienced a loss of propulsion power on the highway, placing my safety at risk and lost all power in a traveling lane of traffic. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. The reduced propulsion power while driving on the highway, coupled with the illuminationI urge the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly to ensure the safety of Chevy Volt drivers and passengers. It is imperative that General Motors addresses these issues promptly and implements appropriate measures to prevent further incidents.

The high-voltage heater control module (also known as the PTC coolant heater / K10 heater module) has failed. This component controls cabin heat and windshield defrost when the vehicle operates in electric mode. The authorized Chevrolet dealer diagnosed the issue, confirmed the failure, and attempted to order the correct GM part. GM informed the dealer that the part is no longer manufactured or available through GM channels. As a result, there is currently no GM-approved repair path. This failure prevents the vehicle from providing windshield defrost while operating in EV mode, which is required for safe winter visibility. I live in New Hampshire, where winter temperatures routinely require functioning cabin heat and defrost for safe operation and compliance with state visibility laws. Because this is a high-voltage thermal management component, there is no safe aftermarket repair option. The inability to obtain an OEM replacement part for a safety-related system prevents the vehicle from operating safely in intended EV mode.

The vehicle losses power at times. Will not take a charge. It states it is in reduced power mode. It appears to be the becm however my vin is not reported to be on the special coverage.

The BECM failed, engine light on, car is at reduced power or doesn't run at all. A message states that there are no EV miles available when it is full to to place the shifter into park. There is a free extended warranty for it (XXX- Special Coverage--Battery Energy Control Module Malfunction - ) but my Chevrolet dealership in Wenatchee, Washington says that it's not covered. I want to know why they said this. I have been stranded without an operable car, unable to get to and from work. If I don't go to work, I can't pay my mortgage. I don't have another car to drive or the means to rent one. It needs to be towed 90 miles to a dealership which that price will be astronomical on my poverty level income. I have cancer and need to get to my treatments. The cost to replace the BECM is $2100-$3000 out of pocket not including towing. The error code was read as a failed BECM by a diagnostic reader and it's having all the symptoms of a failed BECM. It has the following code: P1E00 $07E8Pd Initial symptoms in the prior week before the car wouldn't operate, was that I got a message to put the car into park when it was already in park. Sometimes the display wouldn't work. Sometimes the heater wouldn't turn on in the preceding 2 months. GLOBAL SAFETY FIELD INVESTIGATIONS DCS6812 URGENT - DISTRIBUTE IMMEDIATELY reads that 2016-2018 Chevrolet Volt models are covered. I've attached this letter.

Approximately 3.5 weeks ago my 2017 Chevrolet Volt (105K miles) would not start and then, when it did, was in "Reduced Power Mode". I had to drive home 25+ miles in this low power mode. I brought to my local mechanic (not a Chevrolet dealership) first. They did a diagnostic and told me the issue was "Battery Energy Control Module" - a known issue in 2016-2018 Chevrolet Volts affecting 19,000 vehicles for Chevrolet provided extended warranty coverage for up to 15 years/150,000 miles. See Special Coverage N232432680. I was not able to get an appointment for 9 days at the Chevrolet dealership in Oxford PA. The vehicle needed to be towed there because it wouldn't start. Chevrolet dealership said it was not the Battery Energy Control Module but rather the 12V battery. They replaced battery, I picked up vehicle and paid $525+ for diagnostic and new battery. By the next day, the vehicle wouldn't start again. I brought the vehicle back and they did diagnostic again and this time determined it WAS the Battery Energy Control Module. Dealership said Chevrolet has not included your VIN in the Special Coverage and didn't know why not. I called Chevrolet/GM customer service (800-222-1020) and spoke with two people including an escalation supervisor and both said the VIN for my vehicle was not included because it was determined that would not be part of the Special Coverage they've offered. We went round and round and no one will give an answer as to why there is a KNOWN issue for 2016-2018 Chevrolet Volts yet my vehicle is being excluded. They said they have no ability to change it and include it in the Special Coverage. If months or years down the road, they determine it should have been included then they'll reimburse me. That answer is unacceptable. Between repairs, initial misdiagnoses and repair and rental car fees, I'm out over $5,000.

Vehicle propulsion system failed. According to Chevy dealer the Battery Energy Control Module and A/T Control Park Switch and harness failed. Warning lights came on when the failure happened. Failure happened just past the extended 150k mile warranty. But car in only 8 years old.

EGR valve and EGR cooler failure. Engine power was reduced and EGR fuse kept blowing. Has code for EGR flow failure/restriction. Check engine light remains on even when reset

My EGR system caused a check engine light. P0401 This is an extremely well documented issue on Gen2 Volts, especially 2017 models. Simply searching "EGR" on the Volt subreddit or forums returns hundreds of related threads. This issue can lead to a clogged EGR valve, causing further damage. A temporary resolution is unplugging the EGR valve, which i have not yet done. But this leaves the CEL illuminated, and without daily scanner, I wouls not know if other issues arise, causing a significant safety hazard.
