Gas Recirculation Valve (egr Valve) problems of the 2017 Chevrolet Volt - part 1

Brought car into Chevrolet dealership for intermittent “miss” when driving. Dealer diagnosed it needed an egr valve replaced at a cost of around $4,000. 00 which is a significant portion of the cars value.

My egr system caused a check engine light. P0401 this is an extremely well documented issue on gen2 Volts, especially 2017 models. Simply searching "egr" on the Volt subreddit or forums returns hundreds of related threads. This issue can lead to a clogged egr valve, causing further damage. A temporary resolution is unplugging the egr valve, which I have not yet done. But this leaves the cel illuminated, and without daily scanner, I wouls not know if other issues arise, causing a significant safety hazard.

Egr valve failed in this vehicle <55,000 miles. The egr valve has an electronic component that, when fails, can cause the car to shut down by blowing the "walk home" fuse. This is a safety issue. This is a well documented problem (internet) and Chevrolet refuses to fix it, leaving the owners with an expensive replacement quoted at $3900 (sept 2025). Recommend that it be covered by the emissions warranty, which was recently extended to 150,000 miles and 8 years for other problematic emissions components. An electric vehicle that cannot be driven because an egr valve is faulty - it's a joke.

Thousands of 2014-2017 chevy Volt owners are having issues where the egr valve malfunctions and the engine shuts down. The Volt's egr valve can cause the car to shut down by blowing the "walk home" fuse. This is a safety issue. In many cases cars are in the shop for months because the part is on "backorder". That's my situation-- dealer just told me it's a $2800 repair job, but the part is on "backorder". The car only has 49k miles. . Read more...

I was driving my car from houston to dallas when I got the "reduced propulsion" message and a check engine light. When I first saw the reduced propulsion issue I thought it might be related to the becm issue again since I had already experienced that problem before. In the last few minutes of my trip the ac started to get hot and when I checked the coolant temperature I noticed it was around 240 - 255 f. I hadn't noticed it since there was no warning light for high temperature which I am used to with other cars. I'm not sure of the full extent of the issues yet, but I know for certain that the egr valve has failed completely at about 71,500 miles. This is with very few miles on the actual ice. I typically only use the ice for a few hundred miles of driving each year. Fortunately for me, even though the cel came on for the reduced propulsion I was able to reach my destination. However, when I went to leave, the car left me stranded as the ice would shut down after a few minutes of running. The propulsion system is reduced and the engine becomes unavailable. Only the battery power will allow the car to drive. The f3 fuse in the egr circuit blows if the engine is activated, and has happened multiple times already confirming the egr issue. I have additional check engine lights that are a result of the egr failure to circulate coolant properly. Below is a list of all the cel codes that were pulled: p06db p0030 p0031 p0403 p0405 p0443 p0458 p0489 p0597 p0598 p06da p0ac4 p0135 p0ac4 p16e0 looking into this issue I found that this is an one of the most common failures in the chevy Volts but is no longer covered under the vehicle warranty and no bulletins posted for an extended warranty other than the becm failure. This failure is so prevalent that I am surprised it is not.

Egr valve and egr cooler failure. Engine power was reduced and egr fuse kept blowing. Has code for egr flow failure/restriction. Check engine light remains on even when reset.

Egr valve stop functioning, which caused service not available engine check light on. This is a hybrid plugin, when battery is low, it is dangerous is gas engine not functioning. This egr valve is super expensive, the fix (parts and labor) is over $3300. The car milage was only a little over 58800 miles. Without getting this repaired, the emission inspection will not be passed in virginia.

There is a part that fails on a lot of gm vehicles due to getting clogged (an egr valve). It prevents the vehicle from reaching high speeds on the highway and can fail while driving (which happened to me). I could have lost control of the vehicle on the highway and crashed or gotten rear-ended. Gm refuses to pay for repairs involving this part despite so many people reporting the issue that they needed to do another production run of the part after discontinuing it. Here are many others that experienced this problem: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2017 Volt reported a "propulsion power is reduced" message on the display. When I took the car to the dealership for service, they stated that a new egr valve was needed. The part alone is $1847. The total service with labor would have been over $3000. Looking online, it is a very common issue for the gen 2 Volts. Unfortunately, the dealership is saying this repair is not covered under warranty.

My chevy Volt went into reduced propulsion system power mode, the engine light came on and the vehicle stalled while sitting at a traffic light on [xxx] at [xxx] in tyler texas. Checking the computer and the complaints online I found that my 15 amp #03 fuse (no walk home) had blown. I replaced the fuse and the next day on [xxx] the same thing happened again after driving 30 miles. The vehicle stalled at an intersection outside of tyler texas. The egr valve is known to cause the fuse to blow, so I had no choice but to unplug the egr valve and replaced the fuse and has not blown the fuse since. This is both a safety issue and an emissions issue, but the replacement part cannot be found anywhere to purchase anymore so I am having to drive this vehicle with this ongoing safety issue. Due to the nature of the egr valve blowing the fuse all the time and that it affects the safety of the vehicle a nationwide recall needs to be done on these vehicles to force gm to start making the part again. This is a dangerous flaw that will cause the vehicle to stall and create a safety hazard. This has been ongoing for quite some time with these Volts, and something needs to be done about it ASAP. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

P0401 error egr valve not receiving enough fuel.

Bad egr valve in 2017 chevy Volt, apparently a common problem. Received a check engine light, risk of reduced propulsion (creates risk of stalling and crashing on highway).

Yes this vehicle can be made ready for inspection upon request. According to the registered Chevrolet dealership who inspected my vehicle and gave me the diagnosis - the cars egr valve control board is shorting out fuse #3 which leads the car to enter “reduced propulsion mode” and keeps you from using the generator engine due to being in this mode. This happened as I was driving home from work one day and the car notified me of this issue and entering into this mode. This could leave people stranded if low on battery charge, or in danger due to reduced propulsion. Chevy no longer manufactures this unique egr valve and thus the repair requires obtaining back ordered parts from a manufacturer outside of the us for thousands of dollars. Alternatively you can drive without the egr power cord connected, which means greater emissions and environmental risk/damage. This is not covered under warranty. This is a known faulty part that many Volt owners complain about, which makes it a good candidate for recall. Thank you for your time, shaemus k.

The car has a check engine light and "reduced propulsion" warning. Based on obdii errors, the egr on my chevy Volt failed. I am not in a carb state (I'm in hawaii, though I bought my Volt in CA, which is a carb state). The egr issues plague all gen2 chevy Volts, and tends to break around 40-70k miles into the life of the car. Egr spare part availability is very limited. Given the frequency with which this car breaks for this issue, and the negative impact on emissions, this should be a recall issue nationwide, not just for states that keep carb requirements.

The egr valve failed. This caused the vehicle to have insufficient propulsion while driving. The dealer has confirmed the egr valve is the problem. The vehicle is at the dealership. The check engine light came on. The dealer is now stating the replacement egr valve is a $4000 part because gm stopped making the part when they discontinued the Volt. An egr valve should cost $250-$400 not $4000. The current trade-in value of my vehicle is only $7000. I cannot get my vehicle fixed due to the cost and the vehicle is too dangerous to drive due to the power loss issues.

Several years ago, when I was driving the vehicle, I got a sudden "reduced propulsion alert" and the onboard coolant temperature gauge showed a significant spike in temperature. To avoid overheating, I had to pull over on the side of the highway. In the onboard fuse box, there was a blown f3 fuse. I replaced the fuse and the same issue happened again last year. After some online research, it is clear that the egr valve failed. Unplugging the valve and replacing the fuse has returned the vehicle to normal operations, but it's now out of compliance with local emissions regulations. Gm has failed to properly produce replacement parts. As of Feb 11, 2026, a local gm dealer in bloomington, in quoted a backorder and unclear wait time on a replacement part and quoted me at $2,000+ just for the part. If not for my quick thinking, this part failure could have overheated my vehicle causing extensive damages. Gm has failed to produce enough replacement parts and given the safety issues associated with a blown fuse and overheating, NHTSA should order a recall on this part and force gm to replace the parts for owners. This is a widespread problem documented among Volt owners, and the only stopgap issue is to drive the vehicle out of compliance with local emissions rules.

This is a safety issue for chevy Volt. After seven years of good operation, our 2017 Chevrolet Volt stopped running in traffic while we were driving on 18 Dec 2024. The check engine light was on, and "reduced propulsion" message on dashboard panel. We brought it to the dealer from whom we purchased the vehicle. Tech report paraphrased, customer states ck engine light is on and "reduced propulsion" message on dash fault codes: p0030, p0031, p0054, p0135, p0403, p0405, p0443, p0458, p0489, p0597, p0598, p06da, p06db found fuse [f03] blown for egr valve likely egr valve sticking and causing fuse to blow. The technician stated the exhaust gas recirculation (egr) valve is defective, and needs to be replaced. Replacements are scarce, on backorder, and can be many weeks or months to wait for a part. Many report their Volt unusable, sitting idle, waiting for egr replacement. Egr valve replacement cost is quoted as $2800, which is quite expensive for a valve replacement. This has been happening in recent time to many Volt owners. There are many reports in online forums and no the gm forum website. . Read more...

The vehicle tells me to "stop and shift to park" while I am driving, and power was lost to accessories such as the climate control. Since the egr was identified as the cause of the problem, the car remains on "propulsion power reduced" mode. The egr has been backordered for months, if not years, and aftermarket third-party egr valves are not readily available either. However, there is no recall, and this is clearly a common problem on these vehicles as attested on gm-volt forums. The egr failed about one year ago, but now the message on reduced propulsion power is presented every time I start the vehicle.

Vehicle went to low power mode on the interstate (i4) and was unable to drive at normal safe speeds. Engine overheated and would not allow vehicle to drive over about 10 mph, had to drive slowly on interstate until I could pull off safely to let it cool and get towed home. Technicians verified it is the known egr valve issue, which happens often and isnt covered under any warranty. From research online this is a common problem that strands people in Volts and gm wont fix and cant even get more parts for to repair vehicle. Can leave people with sudden power loss while driving and limit driving speeds to unsafe levels unexpectedly.

While driving, a warning chime sounded and a message appeared saying "propulsion power reduced. " the check engine light also appeared. The car lost power, would accelerate only very slowly, and eventually died along a busy road. After a period, I was able to restart car and drive very slowly to dealer. I was told that the problem was a faulty egr valve, which was blowing a fuse and would do so again. Dealer was unable to find a replacement valve anywhere in the nation. Gm apparently is not manufacturing replacements for this components, and from reports found onliine, plenty of others have had the same problem. The temporary fix is to disconnect the egr valve, which results in increased vehicle emissions. I will be unable to pass my next emissions test next year. The safety issue is that the vehicle can quit running without warning in any situation.

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.

Reduced propulsion power and check engine light. Egr valve failure per mechanic. Part has been on a global back order for 1. 5 years. The car will not pass emissions testing and can blow a fuse that will make the car inoperable. The part is also costly at 2400. 00 without labor costs. My car has 83,000 miles, is well-maintained and only 7 years old and now I can’t drive it or sell it.

The contact 2017 Chevrolet Volt. The contact stated that while driving approximately 55 mph, the vehicle switched over from battery to fuel and a message was displayed that there was no fuel available. The exhaust gas recirculation (egr) valve failure light illuminated, and the vehicle started decelerating. The contact pulled over to the side of the road and restarted the vehicle. The contact continued to drive at slower speeds. The vehicle was taken to the dealer where it was diagnosed that the propulsion power was reduced. The contact was informed that the battery energy control module needed to be replaced. The dealer later found upon further inspection that the egr valve needed to be replaced but was not replaced. The contact stated that after having the repair completed the failure occurred approximately 3 times. The vehicle had not been returned to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 111,722.

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.

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.

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.

Egr valve failed while driving on the freeway. Loss power. Check engine light on. Propulsion power reduced. It is safety and emissions related.

Reduced propulsion message appears on the dash and car lost propulsion on the highway. The egr blew a fuse and the car enters the walk home mode. This problem should be covered under warranty but my dealership says it is not covered. This issue causes the car not to be able to drive. Chevy is back ordered for the part and there is no estimate of when the part will be available. They apparently do not make the part anymore and there is no fix. Th egr seems to have bad soldering and blows the fuse #3.

On July 21st, 2024, the exhaust gas recirculation (egr) valve failed. It blows the “non walk home” f03 fuse, resulting in the check engine light and a “propulsion power is reduced” warning message. The vehicle is not to be driven in this condition. The egr valve is included in the emission warranty parts list and the pzev emission control system defect warranty (15yr/150,000mi) is active on the vehicle. The vehicle has been to two Chevrolet service centers, mission bay Chevrolet on July 22nd and kearny mesa Chevrolet on August 6th without successful repair. They explain that the egr valve part is on backorder and have no estimate for its availability. The vehicle has been at the kearny mesa Chevrolet service department for 55 days. Having the vehicle suddenly and unexpectedly enter a diminished propulsion mode at freeway speeds is unsafe.

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.

July 3, 2024, while driving on pennsylvania turnpike, check engine light came on with reduced propulsion warning. Continued driving to destination without incidence. Did not drive again until July 5th. July 5th 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.

Driving at highway speeds, check engine light came on with a warning of "reduced propulsion power" and sudden loss of speed in heavy traffic. Dealer diagnosed issue as failed egr valve but is unable to source repair part due to frequency of failure causing years-long backorder.

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.

While driving down the highway a "reduced propulsion" message appeared on the dashboard and the drive became very rough if speed changed, also the engine temperature increased but it did not overheat before we could stop. This was diagnosed as an exhaust gas recirculation (egr) valve failure. I spoke to multiple dealers and did research online as well and this is a very common issue on this vehicle. So common that the part is impossible to get and has an eight month wait which means I cannot drive my vehicle. What component or system failed or malfunctioned, and is it available for inspection upon request? egr valve how was your safety or the safety of others put at risk? my car had reduced propulsion, engine temperature increased and it suddenly lost speed quickly on highway when my foot was removed from gas pedal. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no, Chevrolet is aware of this issue and say we just have to wait 8 months for the part. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no pre-warning a "reduced propulsion" message and a check engine light turned on at the time of the egr valve failure.

While driving on high-speed devided highways including stretches where traffic was 2-way (single lanes separated by concrete barrier during road maintenance) chevy Volt indicated "reduced propulsion", and in 2 cases forced shut-down of electric and gas engine where the single-lane travel had cement barriers on both sides of the driving lane. In at least one case, the engine forced 30-40 mph travel until a break in the right-hand cement barrier was interrupted and I could get off the highway. In another case, the engine and fuel propulsion shut down but there was a breakdown lane on the right allowing traffic flow but exposing me to risk due to how close 65 mph traffic was passiing me. In each failure case, after turning off and re-starting the vehicle, the vehicle seemed to have re-set propulsion control and I could continue the trip at normal speed until another warning but not complete faillure occurred (both lanes being available so I could drive to an exit, turn off the ignition, restart and resume the travel). I believe the failure was in the becm (battery energy control module) but the Chevrolet dealer identified an egr failure that prevents their repair team from diagnosing the becm. Whatever the failure was, it put me iin a very dangerous situation in at least 2 points in my 600 mile trip.
