2018 CHEVROLET VOLT

SEAT BELTS:REAR/OTHER

General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.

ENGINE

Electrically actuated EGR valve fails, it draws too much current and blows the F03 fuse (Labeled “No Walk Home”) which has 4 other components on it, this causes “Reduced propulsion” message, soon after the engine overheats due to one or more of the 3 other components that lost power, and the “Engine not available” message appears and the vehicle loses all motive power. This syndrome is well documented in the GM-Volt online forum. Additionally this vehicle has portions of the EV battery that failed, I am still waiting for battery parts to arrive and its been 4 months, many owners have waited between 1 and 2 years for the battery to be fixed, this contributed to this issue as the electric propulsion would have possibly been available if the warrantied battery was repaired within a reasonable timeframe. I was refused a service loaner. My recent contact with Chevrolet customer service suggested I rent a car, and they will reimburse $45 per day, however they insist I pay for it and when the repair is complete, they will reimburse me. There is a gentleman on the Volt forum who has laid out about $5,000 on rental cars for well over a year, and is finally reluctantly getting a buyback, but they depreciated the car but did separately make good on the rental reimbursement. Neither he nor I really want that result, we want the car repaired in a good faith effort, instead both battery parts and EGR valves are in short supply. Currently the GM part is between $1400 and $2500 when in 2024 the same part was widely available for $240. I understand this is a bit rambling, but the context matters, and GM is dragging their feet on servicing the warranty liability they have. My TZEV warranty is good until 2034 and they are actively trying to kill my car off to save the ongoing cost of servicing this warranty. They are also putting owners at risk. Please consider a battery recall and an EGR valve recall. Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM

When shift lever is moved to Park, the car often does not recognize it is in Park and can't be shut down. It takes a lot of time of moving the selector in and out of Park to finally get the car to recognize it is in Park. During an occasion when the car would not go into Park, the car ran for hours while the driver was at work. This seems to be a known issue (micro switch) with this model. This is available for inspection upon request. Safety is at risk because this condition leads to not being able to shut the car down, which leads to the potential for a dead battery and getting stranded. While I have not yet had my car's problem reproduced or confirmed by a dealer or independent service center, there is a lot of evidence in online forums of the prevalence of this problem. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives or others. There weren't any warning lamps, messages or other symptoms of the problem prior to the failure as long as we've owned the vehicle. We purchased this vehicle less than a week ago, on August 2, 2025. The issue presented itself once on our test drive and again intermittently in the six days we've owned the vehicle.

On [XXX], our 2018 Chevy Volt experienced a critical BECM (Battery Energy Control Module) failure while being driven by our [XXX] daughter. The failure caused the vehicle to enter limp mode, resulting in a severe loss of power and the inability to shift properly. Most alarmingly, the brakes failed to function correctly—despite being fully engaged, the car continued to move forward at a red light, placing our daughter in immediate danger. She was only able to safely stop the vehicle by maneuvering it off the road into a parking lot. This BECM defect is a well-documented issue for Chevy Volts from 2016 to 2018. However, Chevrolet has refused to cover our VIN under the existing special service bulletin, despite our vehicle using the same faulty part number as those included in the recall, and has provided no explanation for this exclusion. As a result, we are being forced to pay $2,100 out of pocket to replace a part that GM knows is defective. This is an unacceptable financial burden for a safety-critical issue. GM should immediately issue a recall for all vehicles equipped with this faulty part number to ensure the safety of all drivers and prevent further undue costs.

SERVICE BRAKES

Front brake calipers are sticking on, causing the brake pad to engage the rotor causing excessive heat. Risk of fire when parked in garage. I have had the calipers taken apart and cleaned and greased and still have the issue. I have read many reports on message boards of the same issue with no fix.

ELECTRICAL SYSTEM

When the vehicle is running, and the gear is moved to park, and I attempt to turn off the car by pressing the ignition button, an error shows on the dash display and the message is "Shift to Park". Even though the car is in park, the vehicle doesn't know it. I then cannot turn off my car.

FUEL/PROPULSION SYSTEM

On May 26, the car was running in electric mode and switched to gas because the power batteries were depleted. Shortly after switching to gas mode, lights came on the dash board saying Engine Not Available Get Service Immediately. I was on a highway at the time and fortunately had just enough left to get off and the car would not move any further. Turning the car on and off did not resolve the problem. It had to be towed to a Chevy dealer. Even after an hour, the messages would come on when trying to start the car. The next day, the dealer called and said they could find no problems with the car and it works fine. This happened once before, but that time there was enough charge in the battery to get home and then later it would start without the message.

The contact owns a 2018 Chevrolet Volt. The contact stated that while his wife was driving 60 MPH, the message “Power Reduced” was displayed. The vehicle was taken to an independent mechanic who determined that the failure was due to the EGR valve. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 51,000.

While driving northbound on a freeway downhill, my vehicle suddenly lost power and displayed a "Shift to Park" message while still in motion. I was unable to accelerate, and the engine became unresponsive. The vehicle began coasting with no power, creating a dangerous situation. A semi-truck was in the lane next to me, and a car was behind me — I nearly got into an accident while trying to safely exit the roadway. This is the second report I’ve made regarding the same issue. The unexpected "Shift to Park" malfunction while driving is a serious safety concern that needs immediate attention.

Issue Summary: The Chevy Volt has experienced recurring electrical problems, including the "Shift to Park" message, loss of power, and dead 12V battery. The vehicle had to be towed to the dealership three times due to these issues. One incident involved a power loss while driving at 65 mph, which caused a near-miss with a semi-truck, posing a significant safety risk. Warranty Status: The additional warranty was purchased, but only one of the three incidents occurred while the vehicle was under warranty. Safety Concerns: The repeated electrical failures, especially while driving at high speeds, raise serious safety concerns

EGR valve failure at highway speed of 70mpg on busy road with passenger and service dog in vehicle on a road trip (on ICE not electric). This produces a reduced propulsion in the vehicle and it becomes unsafe to drive. The EGR failure blew the 15A #3 fuse known as the "no walk home" fuse, so I needed to be towed to a parts store then unplug the EGR valve to make it somewhere safe. It was a Sunday, so every dealership (in the VA area at least) was closed. It is a well known/documented issue and the warranties have been extended, but only in a few states with the CARB protections. There are no warnings, if I was not an adept driver, we could all be dead. I also became stranded ~six hours from my home and only ~eight thousand miles outside of warranty. The replacement part costs ~$1800 without labor - the most expensive EGR valve the 60yr old parts employee at the dealership had ever seen, on a hybrid car which doesn't even truly require the part to operate or to pass emissions in some states. I think GM will help me with a goodwill repair in this case, as I have been a loyal Chevy customer my entire life and Volt owner since 2013 - but that is not the norm, so please take action and extend warranty protection to all Volt owners like the BECM issue.

On [XXX], while traveling on [XXX] near Rockingham, NC, the car suddenly decelerated, all of the dash warning lights came as well as a 'Reduced Propulsion' message, stop driving the car immediately. We did, called a tow truck, waited an hour and was towed to Diffenbach Chevrolet in Rockingham. They found multiple trouble codes and a bulletin saying the EGR valve needed to be replaced. (As it happens, these have been on a nationwide backorder for years.) The technician cleaned the valve and the car limped home after it sat at the dealership for a few weeks. BTW, we missed the Iron Maiden concert we were headed to Charlotte for. We then had the car towed from Southport, NC, to Jeff Gordon Chevy in Wilmington, NC. They had it for a while and stated the part was on back order and with no ETA. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The Volt experienced a "Shift to Park" error, preventing it from recognizing when it was in park, even when the gearshift was engaged. While this issue was frustrating, it initially didn’t affect the car’s driving capability. I simply had to wiggle the gearshift until the system registered that it was in park. This problem persisted for a month until one day, the vehicle would no longer shift into any mode, though the "Shift to Park" message remained on the dashboard. The car turned on but would not accelerate. The issue was eventually repaired at the dealership, a process that took about two weeks. During this time, we were not initially offered a rental car. It was only after we called and insisted that the dealership provided one while waiting for the necessary parts. This issue appeared to be a factory defect. While part of the repair was covered under warranty, we still had to pay $685 out of pocket.

Yesterday, my daughter was driving on [XXX] in Seattle traveling around 65mph when the vehicle lost power and reported the error of "shift to park", "Propulsion reduced" and "StabiliTrak failure". Luckily, she coasted to an off-ramp and safely put the vehicle in park. Thankfully she was not involved in an accident, but was very shaken by the experience. After doing some research it seems that the Chevy Volt has a known issue with the BECM and GM has failed to issue a recall, putting thousands of lives at risk. After turning the vehicle on and off several times, she was able to get it started and with minimal propulsion on residential streets was able to return to our house. this morning I dropped the vehicle at our local GM dealer for diagnosis and repair, but wanted to file a report, to hopefully prevent this from happening to another unsuspecting driver/child.
