2017 CHEVROLET VOLT Complaints

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 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.

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 EGR valve had an electrical short, causing the 15A F03 fuse to blow. This causes a "reduced propulsion" message to appear and also causes the vehicle to start overheating. The faulty EGR valve is available for inspection. This failure occurred while we were on the interstate driving 70mph. We were also at least an hour from home/family. The EGR valve short is a known problem with Gen 2 Chevy Volts. Online message boards are filled with posts about this issue. The vehicle was inspected by a Chevy dealership (we had to have it towed). However, the EGR valve is on national backorder with no ETA on when they would be available again. We are currently driving the car with the valve unplugged. However, this causes the engine to run less efficiently and at higher temperatures, so we cannot run it for long periods of time. There were no warnings before the problem occurred, it just suddenly happened while we were driving on the interstate. Luckily we were near an off ramp and a hotel; since the problem occurred on Easter weekend, there weren't any dealerships open.

EGR valve fails causing vehicle to become disabled in traffic or stranded on a remote section of the highway. Also fails emissions testing. Chevrolet has NO REPLACEMENT parts available.

Battery Energy Control Module (BECM) loss of power or reduced power mode occurred came with little to no warning. Hybrid battery wouldn’t accept a charge in its battery.

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.
