2018 Chevrolet Volt

I was driving back from [XXX] on XXX, when I received a "propulsion power limited" message on my dash with a check engine light. I pulled off to a nearby gas station and tried to scan the code to figure out what was going on when I then received the message "Engine unavailable" and the car shut off. I checked the fuse box and found that the F03 Fuse had blown. I replaced the fuse and attempted to start the car again. It began normally, but then after driving 10 feet, I received the "engine unavailable" message again with a check engine light and the car no longer had power and I had to coast into a parking spot. I checked the fuse again and found it was blown. If I had not stopped in the gas station, I would have been stranded on the side of the highway, or worse yet, I would have stalled out on the highway and potentially got hit. I had my car towed to a dealership who eventually completed their inspection of the car on XXX and determined that the EGR Valve had failed (the servo motor burned out and blew the F03 Fuse). This is a well known issue on the 2nd Generation of Volts and it is likely faulty servo motors in the EGR valves. The Dealership even included in its financial assistance request to Chevy on my behalf that the EGR valve failure is a known issue. When asked if there was any preventative maintenance suggested to prevent the EGR valve from failing, the service technician indicated that there wasn't anything that I did as the end user to cause the problem.

While driving on a highway the car started to hesitate, a message appeared on the console "Propulsion power is reduced" and the engine light turn on. After driving some miles, a new message appeared: "Engine unavailable, service soon" and the car only ran on electric power, no motor engine. I had the same problem 3 year ago and the dealer identified the problem as a shorted EGR valve. This time I knew this shorted EGR valve burns the F3 fuse. I managed to get to a car part shop and bough several fuses (15 amp). After replacing the fuse 3 times I managed to get to the dealer. The repairs cost $3000+ (up from $1000+ 3 years ago). This problem is well documented on the GM service technical bulletin "21-NA-116" dated February, 2023. Three years ago I was in the middle of nowhere in South Texas and it took 6 hours to get a tow truck This time I was lucky enough to be close to to a town that the remain battery power was enough to get to the store where I bought the fuses. GM should recall this part and do a proper fix

It was the XXX recall for the DTC P0442/check engine light code. The dealership said that the recall had been satisfied in 6/2020 by putting a buffer in to separate the 2 lines but not replacing the part. Now the exact same code DTC P0442/check engine light in the exact spot that occurred for the original recall. The dealership originally quoted $5,093, then after me complaining that it is the same recalled problem they dropped the cots to $2384. I believe that is an agreement that the manufacturer should cover this. Of course I will have to pay to get my car but I would like the manufacturer to reimburse me for it seeing it was a manufacturer default. I spoke to the manufacturer they flat out refused to cover it. I obviously disagree. Would like you to pressure them to change their decision.

The contact owns a 2018 Chevrolet Volt. The contact stated that the battery module became inoperable. While attempting to start the vehicle, the message "Engine Unavailable - Service Soon” was displayed. The contact was unable to use the vehicle. The contact stated that the TPMS warning light was illuminated. The contact associated the failure with Technical Service Bulletin: 18-NA-261. The contact called the local dealer and was referred to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The failure mileage was approximately 111,000.

My wife and I were on a 200 mile trip and the engine failed about 150 miles into the trip. Was driving and the instrument panel indicated that the engine was in reduced power mode. I switched over to battery power but had only approximately 10 miles of range left so after a couple of miles I switched back to engine power and was almost immediately informed by the instrument panel that the engine was in failure mode. Was fortunate that there was an exit nearby and was able to use the remaining battery power to exit the highway and pack the car before there was no power.the car was towed to a dealer and we were told that the egr valve and cooler had failed.they were replaced and I was told that they were not covered by the federal emissions warranty so the cost would be $4000.the car was driven with the vast majority being electric power.

The EGR valve clogged, causing a a servo to blow the F3 fuse, disabling the engine while driving. This occured suddenly while driving on a busy road with no shoulders. I managed to coast into a parking lot not too far away but I had no charge left in my battery. I could only get the engine to start back up for less than a minute at a time. I got my car inspected by Chevrolet and they confirmed they issue. Very shortly before the engine cut off, the car started jolting. There weren't any warning lights or error codes before this.

The dealer reported having repaired an emissions recall for a fuel vapor leak, however the repair was ineffective and the vehicle still reports the leak as a fault code "slow" and "fast" emissions leak. The dealer refused to recheck their work without payment. Recently I came into possesion of a borescope camera and was able to photograph the dealer's "repair". The photos clearly show the parts for the emissions repair are located in the wrong place as compared with GM's own service bulletin. Therefore the dealer did not do the repair, or failed to do the repair, and refused to check there own work without compensation when informed of the continuing problems and left me to do their recheck of their work at my own expense. I have provided photos of the GM prescribed parts placement and the incorrectly placed parts in my car as well as the resulting damage. We never experienced the relief intended to be provided by the repair service. They claim to have performed the necessary recall service, but THAT IS A FALSE CLAIM. See Chevrolet TSB N192273600. NOT PERFORMED CORRECTLY SO FAILED. The dealer, Haselwood Chevrolet, Bremerton Washington, was contacted by phone and email but offers no response. They have the pictures of the botched repair job. Additionally the car needs warranty service for a bad park switch which service they refuse to perform without my agreeing in advance to pay for that in warranty repair.

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)

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.
