2017 Chevrolet Volt

Component or System Malfunction: The Exhaust Gas Recirculation (EGR) valve in my Chevy Volt failed, causing a complete loss of vehicle power and potentially leading to engine overheating. This malfunction has been widely reported among other Chevy Volt owners, and the EGR valve has been improperly designed. The part is not available for replacement, making it impossible to fix the issue, even though Chevy lists the cost at $3,000 to $4,000. See [XXX] as a sampling of people experiencing the problem. Safety Risks: The failure of the EGR valve puts both my safety and the safety of others at serious risk, as the sudden loss of power could result in accidents, especially when driving at higher speeds or in heavy traffic. Additionally, the potential for engine overheating increases the risk of further damage or even fire. Problem Confirmation: This problem has been reproduced and confirmed by my local dealer, who informed me that replacement parts have been back-ordered since April, with no estimated delivery date available. Many other customers are experiencing the same issue and have also been unable to obtain the necessary parts. Inspections: The vehicle has been inspected by the dealership, but no solution has been provided due to the lack of available replacement parts from the manufacturer. The manufacturer has not offered a viable timeline or alternative resolution. Warning Signs: Prior to the failure, I experienced warning lights related to engine performance. These warning messages first appeared in April, signaling an issue with the EGR valve. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Received the vehicle on 8/6/24 with 96,500 miles on it. On 8/15/25 I received a check engine light with error code P0401 indicating an issue with the EGR Valve. I took the vehicle to my dealership which confirmed the issue and was informed that it was a common failure with this type of vehicle. I was placed on a waitlist for the part which as of today, 9/9/24, still is not available. A quick Google search shows that that this error is extremely common for these vehicles.

I was driving on a highway around 70 mph on cruise control, without warning a “propulsion power reduced” message came up with the check engine light turning on and the car stopped accelerating/let off of cruise control. Very dangerous when driving at speeds above 70mph. I took the Car to Chevy and they said it’s a EGR valve issue and that it would cost roughly $3,800 and the part is on massive back order. r Reading online, there’s many Volt drivers with the same issue and can’t get the part for months on (with some being offered a repurchase of the car from GM so the problem would go away) it seems like Chevy and or GM do not have sufficient parts to fix the massive amount of Volts having this specific problem and on top of that, this is the largest quote I’ve seen for this repair.

Purchased the '17 Chevy Volt for my Daughter on [XXX] with 58,867 miles. On [XXX], 60,600 miles; She was driving on the interstate when the engine temperature spiked, followed by a check engine light and a warning message: "Engine unavailable." The vehicle suddenly lost power when she reduced pressure on the accelerator, causing a rapid reduction in speed. nearly causing her to lose control. The vehicle's OBD Codes were scanned at a nearby auto parts store resulting in 30 DTC appearing. I found hundreds of complaints and posts about the F3UA fuse blown and a faulty EGR valve. A service bulletin for this issue was published by GM in Feb 2023. I notified the dealership of the issues and the vehicle was brought to Deacon Jones Chevy of Clinton, NC on July 16th. The service department informed me that the 12V Battery was bad and needed replacement to "correct" the issue, at a cost nearly $550. I asked if the fuse mentioned was blown and was informed that it was not. The check engine light was cleared and my daughter drove home. Before getting home, the check engine light came back on, the temperature spiked, and "propulsion power is reduced." message appeared. This was accompanied again by a rapid reduction in speed nearly causing a collision. I called the dealership back and informed them of the incident. They requested to have the vehicle brought back to the shop, however, towing was out of the question because the dealership is 70 miles from me & I did not want to drive the car in its condition. I took the vehicle to Team Chevy in Swansboro, NC, who ran proper diagnostics. I was informed the F3UA fuse was blown, caused by a short in the EGR Valve. The original dealer offered to split the cost, but Team Chevy said they could get the part & match price. When ordered, it showed the EGR Valve was backorder with no ETA. 6 weeks in and no safe transportation for my daughter and grandson. Significant safety issue with no replacement parts or accountability, ludicrous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR

The EGR (exhaust gas recirculation) valve has failed, which causes issues with the fuel propulsion system, can cause the cooling system to fail, and affects the emissions system. We are unable to obtain a replacement valve anywhere and have been on a waiting list at the dealership for months. The car is not safe to drive in this condition.

The contact owns a 2017 Chevrolet Volt. The contact stated while driving at an undisclosed speed, the vehicle stalled with the message “Gasoline Engine not Available” displayed. The vehicle was restarted; however, the failure recurred. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the EGR valve had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000.

The contact owns a 2017 Chevrolet Volt. The contact stated that the vehicle was lagging and hesitating before accelerating. The contact stated that an excessive amount of pressure was needed to depress the accelerator pedal while driving. The contact stated that the vehicle had experienced reduced Hybrid propulsion. The contact stated that the check engine warning light was illuminated. The failure was intermittent. The vehicle had not been taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer had not been made aware of the failure. The failure mileage was 140,000.

While driving my 2017 Chevy Volt on the highway, a “Propulsion power is reduced” message appeared accompanied by the CEL. Prior to this there had been no indication that anything was wrong. The warning was quite vague and it wasn’t at all clear what it actually meant so I continued driving. Shortly after this, I began to notice a bit of a “chuggle” or lurching sensation (particularly on hills). This made the acceleration slightly unpredictable, and at one point even triggered the forward collision warning when the car accelerated a bit after I took my foot off the gas pedal (coming up behind another car at a traffic light). I pulled over and attempted to figure out what the issue was. I had a notice regarding the BECM recall in my glove box which listed a reduced power mode as a potential symptom, so I scheduled a service appointment (figuring it was that) and continued my trip. I stopped to get gas, then a mile or two down the road the engine overheated and shut off. By sheer luck I had a few miles of range left in electric mode which allowed me to pull over safely, but I was now stranded over 100 miles from home. I managed to get the vehicle to a dealership in Danvers, MA where they diagnosed the problem as a failed EGR valve. My understanding is this is related to a defect in the valve electronics.The valve failed and blew the F3 fuse, which also supplies power to the engine cooling system. It doesn’t take long for the engine to overheat and it seems this can lead to a complete loss of power while driving when the electric range is already depleted. The valve is currently unplugged while I await a replacement but there is no word on how long that might be. Other Volt owners have had to wait months or even years to get a new valve. The repair quote I received is also unreasonably expensive (> $4,000). I failed my state emissions inspection and am in the process of applying for a waiver. Given how common this is, I'm surprised this isn't already a recall.
