2017 CHEVROLET VOLT Complaints

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.

This car has a failed EGR valve which first became evident in March of 2024. There are no parts available, this in an emissions issue but the failure causes blown fuses which can cause the car to completely stop running which is a safety issue. Reduced propulsion is a symptom which is dangerous and this has been confirmed by three Chevy dealerships. I have had the EGR valve cleaned to the tune of $1200, have a deposit on a new valve which doesn't seem to exist for $850. There were no other messages before the failure. I am driving the car with the EGR valve disconnected, mostly on the battery power but no end is in sight to this problem.

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.

Vehicle began exhibiting issues with BECM, reduced propulsion/limp home mode with range-extender activation. Car unexpectedly stopped running in the middle of the road, came to a complete stop and unable to move off road under car's propulsion.

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.

I was driving on the interstate when my check engine light came on and the car told me it was going into reduced power mode. I then had to limp my car along on the interstate till I could get off the road, many close calls going 45-50 mph on a 70 mph road.

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.

EGR Valve issue. I have a 'reduced propulsion energy' notice on the dash. Unable to get repaired because there is no parts. This is a common problem with these Chevy vehicles. Emissions test won't pass

Egr valve failed. GM has this part in a national control status. Vehicle should be under warranty per the handbook but dealership is denting this. Dealer solution is to just disconnect the part and says it is safe to drive. Not comfortable with this since I have had this vehicle modified to allow myself who is handicapped the ability to drive it. Dealership wants prepayment of part before placing the order for it. Part is expensive and they have no idea how long they will be using my money before or if the part is available.
