2017 Chevrolet Volt: engine failure

Filed Sep 14, 2024 · Engine, Fuel system · CA

Experienced severe engine failure while driving on the freeway, which cost to be in operable due to failure of EGR valve. This is a warranty repair however GM has part on backorder for over a year with no plan to fix. My car is now disabled and I have no other transportation.

Driving at freeway speeds when suddenly the cars propulsion power failed and I went from 75mph to 45mph with no warning and no way to accelerate. Happened multiple times even after pulling over and turning the car on and off. I was told by the dealership that was a gas engine part and that I could drive it on the electrical engine only. When attempting to drive on the electrical engine, I received a notice of engine failure and had to coast into the driveway of a dealership. I was told the engine “could explode” if I continue to drive it

The contact owns a 2017 Chevrolet Volt. The contact stated while driving 65 MPH, the Hybrid battery drained; however, the engine failed to activate as needed. Due to the failure, the vehicle stalled, and the contact coasted the vehicle to the shoulder of the highway. Due to the failure, the vehicle was initially towed to the residence then to the dealer. The vehicle was kept in dealer possession where repairs were made to the ECM (Electrical Control Module). Since the repair, the contact stated that the vehicle intermittently failed to start up while depressing the START/STOP button. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.

I received a 'Reduced Propulsion' message along with a check engine light and that progressed to a 'Engine not Detected" message and stranded along the interstate in a dangerous situation. Had it towed to a dealership which had a technician which could work on a volt - he replaced the Engine Control Module fuse which "fixed" the car for about 15 miles and then the 'Reduced Propulsion' error with the Check Engine light appeared. Technician said something must be shorting out the fuse. Dangerous situation.

While driving on the interstate at 75 mph I had to accelerate briefly to allow another vehicle to merge safely onto the road. Immediately my dashboard gave me a warning message saying “reduced propulsion acceleration may be limited” and the engine warning light came on. The temperature of my coolant began to rise over 230 F & then 240. Miles from my destination, I reduced speed & took the next exit to stop for fuel and read my owners manual. I discovered that the same message could appear if the car was not put into “mountain mode” thereby failing to reserve a certain amount of energy in the battery. I had hoped we starting the engine & resetting the computer with the car in “Mountain mode” would resolve the matter, but that was not the case. I let the engine cool down for a bit & restarted my trip as I was just 20 miles away from my destination. Later on, I got another message as my engine began frequently skipping and sputtering that told me my “engine as not available” despite having a bear full tank of gas. I pulled over to read the manual & discovered that this message indicated once my car ran out of electric energy it would just stop working! As I had been on the road for 6.5 hours prior, I knew there was no electric reserve to pull from & said a prayer that my 4-yr-old daughter and I could get safely and get a tow to the dealership. The “reduced propulsion” message is part of a recall on the gen2 Volt, tho that recall relates to a software glitch & the remedy just provides “additional warning time” for this serious issue. My car just turned 5 years with 33,000 miles on it. I have followed all maintenance recommendations. Seems like an electrical emissions issue, & with a lithium battery on board, fire from overheating scares me as much as than engine failure on the interstate. But I had a full tank of gasoline! Dealer says it is a “short in my EGR Valve” & that part needs replacing.

While driving to the dealership to get my car serviced for nearly stalling at a stop light my car engine kept turning on and off and revving up and down randomly. I was in electric mode and the engine should not have been coming on. The car's speed randomly fluctuated as the engine randomly revved up and down. I pulled in to a grocery store parking lot where my car died. Before dying the gas range indicator changed from 87 miles to 'low fuel'. I called the dealership to have my car towed. After 16 days I got my car back. The dealership replaced the engine control module twice. The first replacement failed within a 1 mile test drive by the mechanic.
