2018 CHEVROLET VOLT Complaints

Reduction of power , impossible to charge the kilometre says 21 kkm drops from 21 to 0 and the mountain settings dont run, I drive on maintenance , when charging at paying station does not charge,

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.

The contact owns a 2018 Chevrolet Volt. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the EVAP pipe was rubbing against the air conditioning hose connector. The dealer informed the contact that the vehicle was previously repaired under GM Campaign Number: N192273600; however, the failure persisted. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 84,800.

EGR valve clogged and failed on a long trip, bricked the car and had to tow many miles back to home shop. now have been waiting 9 months and still no idea when the part will be available from Chevrolet. My shop and I have claims to Chevrolet for the part for service but still nothing and is getting so we are inconvenienced in travel.

Randomly getting Propulsion power is reduced and loss power while driving. Been force to pull over to the side on the freeway to restart the car.

The contact owns a 2018 Chevrolet Volt. The contact stated that while the vehicle was parked and shifted to park(P), the message "Shift to Park" was displayed on the instrument panel and the vehicle was inoperative. The contact stated that the vehicle was operative while in low power mode; however, the vehicle intermittently failed to charge in low power mode. No warning light was illuminated. However, the vehicle displayed the full battery icon on the display, but 1 EV Mile. The vehicle was taken to an independent mechanic where it was diagnosed that the battery energy control module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 11,000.

The BECM (Battery Electric Control Module) failed in November of 2023. Mountain Chevrolet has had my vehicle since then, claiming to be unable to find replacement battery module. The vehicle is available for inspection at Mountain Chevrolet (it has been left unlocked, unprotected, and exposed to the elements for almost 15 months now). When the BECM failed, the vehicle lost virtually all power and slowed dramatically from highway speeds to ~20 mph. There were no warnings prior to the failure.

When putting my car in park and shutting it off the dash board tells me to shift to park, and car does not fully shut off.
