2016 Chevrolet Volt

EGR valve failed. When switched from Battery to gas car stalled and we were stuck. Dealer said it needs a new EGR valve. But it was on back order. This was a year ago and Chevy still claims the part is on back order! Now the car is ready to renew registration. But it cannot pass inspection because it must have been driven on gas for many miles for the inspection to work! The part is obviously no longer available and Chevy has not offered a solution.

The BECM has failed and causes a reduction in engine power. There is a Special Coverage N232432680 for this issue. Dealership Service Center is saying my car doesn’t qualify based on the VIN, even though it matches the year, make, and model on the Special Coverage. GM is failing to cover the issue despite it matching everything on the Special Coverage.

2016 Chevrolet Volt with 126,500 miles had a sudden loss of power while driving. Towed to Chevy dealership for diagnostics and was told it needed a Battery Energy Control Module. Doing my own research, I see that NHTSA issued a notification regarding GM coverage for this issue (see below). However, my VIN is not covered. Very conveniently, GM covering only one third of the Volts made in this time frame and this is unacceptable. There should have been a recall but at least they should cover the cost to replace under this special coverage. Losing all power on the road while driving is really scary and very dangerous. Please advise if there is any course of action that NHTSA can take on this matter before I go and spend $3000 to have this repaired.

I was driving at normal speed full tank of gas and electricity, when I got an error message "propulsion power is reduced". I was in the middle of the highway and the car would no longer let me accelerate. I was able to pull of on a small street. Car's check engine light turned on, my steering wheel became hard, and everytime I try putting it on reverse or drive, I get a message to put the car on park. It no longer works. I had this happened once about 3 years ago, and after an hour, it started working normally (this time the engine light stayed on though and car no longer works). I have had the message "propulsion power is reduced" pop up on my screen multiple times, car reduces power, but continues to work. This time it no longer wants to run and I lost all speed in the middle of the road.

I bought the car new in 2015 and after about only 40,000 miles I began getting a Propulsion Reduced error and the car would have very slow acceleration. I took it to the dealer and they replaced the accelerator for $500. It drove fine for a month, but then the acceleration was reduced again. I took it back to the dealer and they were stumped. They wanted to charge me $1300 just to replace some wires, but they weren't confident that would fix the problem. I declined. As it stands now I can toggle the F08 fuse and that temporarily fixes it for about an hour or so, but the error always comes back and the car has a hard time accelerating. Not safe. I called GM and they suggest I take it to another Chevrolet dealer, so I'm going to do that. I'm also going to reference NHSTA Special Coverage N232432680 Battery Energy Control Module Malfunction to see if they can replace the BECM. This is a common problem with 2016 Chevy Volts. If they can't fix it, I'll look into the California Lemon Law to see if I can get my money back on the car. I appreciate your support on this.

On [XXX], this Volt was towed to the Dealer because the Volt would not start, would not charge, and the engine light was on. The Dealer claimed that the problem was the Chevrolet Volt Battery Energy Control Module (BECM), GM Part # 24296900, which was covered under the GM hybrid VOLTEC warranty (8 years, 100,000 miles). On [XXX], 2024, this Volt (VIN [XXX] ) was towed to the Dealer again because the Volt would not start, would not charge, and the engine light was on. The Dealer claimed that the hybrid battery connectors were corroded, the disconnect relay should be replaced, and the BECM should be replaced again at a total cost of $5,005.58. On [XXX], GM issued special coverage warranty N232432680 (15 year, 150,000 miles) to cover BECM replacements for a malfunction involving the BECM. Plaintiff checked the VIN at the GM Recall and Warranty Center website. The Volt at issue is covered under special coverage warranty N232432680, according to the GM website. Plaintiff asked the Dealer and GM again after [XXX] about warranty coverage for the BECM at issue. GM responded that the bumper-to-bumper warranty expired and that they would provide no assistance. On [XXX], Plaintiff filed a complaint with the local Better Business Bureau (BBB) regarding the BECM at issue. GM responded in writing that the bumper-to-bumper warranty expired and that they would provide no assistance. Plaintiff sought arbitration, but both the local BBB and the BBB Auto Line found that Plaintiff was not eligible to arbitrate with GM due to GM’s program summary guidelines with the BBB. GM breached multiple warranties and failed to provide sufficient repairs, and this Volt has been out of service for more than 80 days. Based on GM’s warranty breaches, insufficient repairs and inconsistent statements, this Volt poses serious safety concerns.

GM issued a special coverage warranty for 2016-2018 Chevrolet Volts that had a BECM failure. However, they did not include all of the Volts. We have a 2016 that has a catastrophic BECM failure. The car won't start and the only indicator was the day before it said the vehicle didn't charge. This appears to be the same issue, but Chevrolet did not include our model. We have about 87k miles and are only 3 weeks past the original warranty.

The EGR valve failed part way through a long drive between cities while at interstate speeds. This caused the vehicle to produce a warning about reduced propulsion power (as well turn on the check engine light), and it became difficult to maintain speed with the surrounding traffic. I could maintain speed, but only in electric-mode, and my battery didn’t have enough energy to get me to my destination on that power alone. While in ICE mode (internal combustion engine mode) it would also quickly overheat. I reached my destination by repeatedly swapping between ICE and battery modes, to both extend my vehicle’s range as well as mitigate overheating. Upon arrival at a dealership, I was informed there’s a nation-wide shortage of EGR valves for my model of car. Despite escalating the issue with GM/Chevy’s support staff, they cannot locate an available EGR valve. This shortage has lasted for more than 4 months now and my car remains stuck in a distant city. This part is necessary to operate the vehicle safely, but they have not been producing enough of the part.
