The EGR valve in my Volt suddenly failed with NO warning while driving 70 mph on the highway. I had to pull over before the engine overheated and I stopped on the side of interstate in a very tight shoulder on a curve with traffic and semi trucks passing by very closely. I-??ve now been waiting over one year for repair as Chevrolet is unable to make this part for a repair that is still covered under warranty. Very disappointed and I hope this report will help push a larger message through that Chevrolet is being irresponsible with making parts for the needed warranty repairs.

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

Service brake booster emits a semi continuous tapping/clicking noise. Chevrolet state that it is not a safety issue and does not require repair. However, it is difficult to have confidence in the braking system while this sound persists and it is a constant distraction while driving. Plus, the ability to sell or trade the vehicle in this condition is diminished. Elimination of the noise involves costly removal and replacement of the brake booster assy. Chevrolet fixed an apparently identical issue on the bolt model with a software update, but currently have no intention to do anything similar for the Volt model.

EGR Valve short circuit caused F3fuse to blow causing engine light to go on and Propulsion reduced power warning. The F3 fuse affects 4-5 other systems.

Three incidents in the last few weeks. My 2017 Chevy Volt today has about 84,000 miles. First incident, While driving on an interstate at about 50 mph I suddenly lose ability to accelerate. There was some beeping, dashboard turns yellow, I get a low fuel warning and I cannot accelerate. I pull over on interstate. Re-start vehicle and car restarts. Second incident, driving about 20 mph leaving a neighborhood. I have 4 passengers, all kids. The same exact error happens. I-??m unable to accelerate though I-??m pushing down on gas, fuel light turns yellow. Low fuel light. I pull over. I restart vehicle. Car starts normally. Car goes into shop. Chevy dealership says it-??s the catalytic converter. About a week later, 3rd incident. Entering highway at about 60 mph, trying to accelerate and merge into traffic doing 70 mph. I cannot accelerate past 60 mph, I hear the beeps, fuel gauge turns yellow, low fuel warning. Check engine light turns on. Several days prior to this, I had a low propulsion error on dashboard momentarily. But it went away when I restarted vehicle. Safety of myself, passengers and other drivers were out at risk as there was no warning that I would lose ability to accelerate. There was a no fuel warning but my gas tank was mostly full.

The car stalled at a high rate of speed on a freeway because of EGR failure. Engine check light is on, along with a warning about a critical problem with emissions system that requires immediate attention. The part is out of stock in all dealership within a reasonable reach. The problem is under warranty, but I have made multiple attempts to fix this issue with no success.

EGR valve failed. This can cause the Volt to stall in traffic. No ETA on replacement. The situation seriously limits driving ability. Reduced propulsion and engine light came up. f3 fuse blew related to failed EGR. This is a known issue with Chevy Volts. It was checked out by dealership in Aug. They replaced fuse and basically said can only drive on electric. If turns over to gas it could cause major problems.

The EGR valve had failed, causing a check engine light, which turned into a blown fuse. The fuse blowing left the vehicle stranded until I unplugged the EGR valve and replaced the fuse. I drove it to a shop, where they replaced the valve and the car has been functional since then.

The EGR Valve on the vehicle went bad, causing the vehicle to display 'propulsion reduce' and 'engine not available' errors on the dashboard before the vehicle came to a stop while driving on an interstate. Searching this issue for the Chevrolet Volt online yields a significant amount of similar issues experienced by other Volt owners. Vehicle was inspected and repaired by a Chevrolet dealership, but seems to be a recurring issue with very limited parts supplied by GM, leading to potential of very long delays in repair time.

Failure of the BECM and -??Shift to park-?? message. The vehicle will spontaneously produce a shift to park message when starting up the vehicle and turning it off. The vehicle will also show a 0 mile EV range and use the engine where a message saying -??propulsion power reduced-??. This will also cause the car to shut off randomly. The vehicle has not been inspected by a shop or the dealership. There is no warning or message when this happen. Check engine will appear once the vehicle has these issues.

All of a sudden while braking on a freeway offramp, the check engine light came on and a reduced propulsion warning came on my screen. The car ran weird for about a day, then it wouldn't start. I had it towed to a dealer, they diagnosed the BECM went bad, now my car has been there 2.5 weeks and there's no estimated ship date for the part, much less repair date. If they said they had enough parts for BECM failures, they're either lying to you or they're lying to me.

During a drive the car began warning of loss of propulsion. The vehicle is at a dealer waiting for repair since Oct 16, 2023. There is no ETA on back ordered EGR valve that the technician anticipates a fix.

In 2020 my 2017 Chevrolet Volt had an intermittent problem turning off. My Chevrolet dealer worked to fix the problem. This March I had an accident which involved me thinking the car was shut down. I was half way out of the car when I realized it was moving. Before I could get completely in to apply the brakes, I had hit and pushed an object into a building which caused damage to the building and my car. The was a police report which states that I was at fault. My car was towed to my. Chevrolet dealer for repair. The repair took about two months mostly due to obtaining shifting parts. I can now drive the car but the parts to replace the shifting mechanism is still on back order. It is now early October. The -??shift into park-?? as I think the problem has been named, is still an intermittent problem for me. Sometimes the car shuts down promptly as it should. Sometimes however, I go though the process of shutting down a few times before I am confident that the car has really turned off. I would like to know if this defect has caused other accidents. If so, it my mitigate my responsibility for my my accident which has caused me grief and a large increase in my insurance premium. Another reason I am writing is because There has been a report of a fatal accident in Vienna Township, near Flint, Michigan involving a women being pinned under her car after exiting to check her mail box. The article in -??M-Live-?? paper by Joey Oliver [XXX]. The supposition was that she thought her car was in park. I am hoping that the investigators of her accident would consider the possibility of the car being defective. I believe the police report number [XXX] by officer [XXX]. [XXX], 8525 E.

After looking up an issue with my Volt, I learned that this is a big safety issue and very common. When I put the car in park there is now an intermittent issue that says "shift to park" on the display and the car will not shut off, and I cant confirm that the car is actually in Park.

Door locks fail to lock or unlock on occasion. In certain scenarios this leaves the driver and passengers with a feeling of being unsafe.

The evaporative emissions pipe has a hole in it. This same issue has been previously associated with a recall. The dealer (Andy Mohr Chevrolet - Plainfield) reported that it was fixed in 2020 and declined to do service without me paying for it.

- Indianapolis, IN, USA

BECM failure. Initially, it caused the vehicle to operate in a low propulsion state. However, it now prevents the vehicle from starting. Likewise, I have heard it has stopped the engines from working/shut down the engines while people are driving on the highway.

The two original equipment hydraulic struts that support either side of the rear trunk lid failed. It is available for inspection. The safety of my husband and I is/was put at risk because when you open the trunk, the lid is not staying up like it did, causing it to crash down on your head, back of neck, shoulder, arm, hand, etc., causing injury that is potentially fatal. The faulty parts are still in place and not inspected yet by a dealer, service center, police or insurance company. No warnings given for this faulty equipment, hence the danger of its unexpected suddenness. It started about 2 weeks ago. I spoke with General Motors, the Florida DMV and the Chevrolet dealership where the car was purchased and is taken for repairs.
