2017 Chevrolet Volt

[XXX], while driving on [XXX], check engine light came on with reduced propulsion warning. Continued driving to destination without incidence. Did not drive again until [XXX]. [XXX] while driving using "hold" method of propulsion using internal combustion engine, check engine light remained on, after the engine warmed up, all of the sudden, there was a noticeable reduction of power, followed shortly by the internal combustion engine shutting off while I was entering onto an interstate highway ramp. Fortunately I was able to pull off to the side of the road and back down the ramp without incidence and return home under grossly reduced battery propulsion. July 8, took vehicle to Chevrolet dealership (Baierl Chevrolet, Wexford PA) under battery power. Was told ECM module was bad. ECM module was replaced, error codes cleared, vehicle ran as expected. after driving approximately 50 miles, check engine light with reduced propulsion warning returned. Turned vehicle around and returned to the same dealership. Was told EGR valve was bad while blowing fuse F03 (Non walk home circuit). The dealership did not have a replacement in stock and it would take 7-10 days to obtain a replacement. I had to rent a vehicle out of my own pocket to return home for employment purposes. July 11th, I emailed dealership's service advisor for status of replacement part. Never heard back from service advisor. July 15, 11:24 am, talked to dealership service advisor, was told part was in transit with no estimated delivery date. July 22 called service adviser and left a voice mail message for a return status call. Never received a return call. July 23, called dealership, talked to parts department for part status, was told part had not shipped from warehouse yet and there was no estimate on shipment. After having to return the rental vehicle, I am without a vehicle for my daily required activities. Not an acceptable situations.

I was driving down the highway at normal speeds when I noticed the engine temperature began climbing out of the blue, and eventually the CEL light came on before the dashboard read "Propulsion Power Reduced" and eventually the engine stopped entirely and I had to coast to an area on the side of the highway where I could pull over. The battery-only part of the car was drained but there was plenty of gas in the tank, so my only way out was via the ICE. I turned the car off, waited for it to cool down, then turned it back on, only for the same issue to occur within another couple of miles of highway driving. I had to repeat this process until I was able to get to an exit and coast to a business that would let me recharge the battery enough to drive on battery-only where I could park it overnight, as I was not near my home. Eventually I had to get the car towed to a dealership, where I was told it was either an EGR valve or EGR cooler that needed replacing. After the dealership refused to provide any specifics regarding the diagnostics in writing, Chevrolet corporate informed me that it was an EGR valve that was requested and is on global backorder. This issue has not been resolved for a year now, and put me in the extremely dangerous position of losing power entirely on the highway with almost no warning, and no statements to date that would have prepared me to deal with this issue.

I had the BECM fail as part of many 2017 volts with this issue at around 40K miles. This failure has caused multiple near accidents with immediately losing power at highway speeds. The last time this happened (after the BECM was replaced) was a couple of weeks ago. They said the reason for the failure was a programming issue, and they have updated it. It is flabbergasting to me that a programming issue can result in such a dangerous result. The car reduced propulsion on the highway and got stuck on the offramp while trying to pull over on the busy highway. Not only were we left stranded on the highway with me being 8 and a half months pregnant, but my husband almost got into an accident twice while trying to make it over safely. Chevy needs to be accountable for these significant failures that seem to continuously happen to Chevy Volts. It's not just the BECM - they have multiple things that are causing extremely dangerous results. When they replaced the BECM they also replaced the 12V (with significant out of pocket cost to us) and leaving us with no vehicle for a long time. We bought a new car right after this incredibly scary incident.

The propulsion system stopped working altogether while the car was in motion. The battery charge gauge went from 1/2 to full. The charging information screen displayed a message reading "unable to charge." The air conditioning only blew out hot air, but the coolant temperature gauge read 194-degrees F (within "normal"). The "check engine" light also came on. Diagnostics found the F3UA fuse blown and a faulty EGR valve. A service bulletin for this exact issue was published by GM in February 2023. The company is aware of the issue but is leaving it for customers to discover while operating the vehicle. Safety inspections and oil change centers do not catch this issue. This is a safety concern and should be recalled immediately.

check engine light has been on since Oct of 2023 due to needing EGR valve. Dealership placed order for part number 12691147 in Oct and says it has been on backorder from GM with no estimated delivery date. I just placed an order for the same part via GM parts center. Again, says on backorder. Is there anyway to get a hold of GM parts to escalate getting this? We cannot get the car inspected with this issue and are worried about the safety of the car.

I have needed a new EGR valve for my 2017 Volt for 11 months now. GM told me this in August of last year. I was able to continue to drive the car (without a passing inspection) since then, until recently I was on the highway and my car simply stopped responding to the throttle. I slowly coasted to a stop on the shoulder and was eventually able to get started and off the road, into a parking lot. This is a serious safety issue as I ended up going 20 mph on the highway for a while, which easily could have caused an accident. GM needs to be held responsible for not supporting this part in a timely manner. This is a known issue amongst Volt owners and GM does not seem the least bit interested in making things right.

On a recent trip on a highway on our 2017 Chevy Volt, the Exhaust Gas Recirculation [EGR] failed and caused "low propulsion" errors. We ended up with a surprise bill of more than a thousand dollars to replace the EGR cooler assembly, but the problem was not resolved. The dealership then said we need to replace the EGR Valve which is estimated above $2700 plus labor. Upon checking the GM-Volt users community this is a reoccurring issue on several thousands of vehicles and the inflated price is due to the fact that GM redesigned the EGR valve to fix their original faulty design. We as consumers shouldn't be responsible for such an outrageous cost and mainly safety due to a design flow by GM. This issue should warrant a recall by GM to fix the issue once and for all.
