NHTSA Complaint #11562383 — 2017 CHEVROLET VOLT

Loss of Motive Power due to EGR Valve. I was driving down the highway when I experienced a loss of motive power and the Volt entered a reduced power state while in moving traffic. After the EV battery ran out and the ICE turned on, the following message showed up on the instrument panel "Propulsion Power Is Reduced" and the check engine light turned on. The Volt slowed down and would not accelerate to the speed of the moving traffic. I was able to get off the highway and drive home under reduced power which was still not safe. The engine ran very rough on the way home and was not able to maintain speed high enough for the flow of traffic on the roads. The dealer diagnosed the issues as a failed EGR Valve. The part was on backorder for about a month. In that time, a GM trained technician deemed the car operable (according to GM standards) and said that I could take it back and drive it on electricity only. Unfortunately, that meant that the EV range is about 40 miles in winter after a full charge and running out of electricity would again result in a hazardous loss of power. The behavior of the car under this reduced propulsion is Identical to the one in investigation PE23022 - Loss of Motive Power due to the Battery Energy Control Module. The Chevy Volt EGR Valve issue is a common problem reported in other NHTSA complaints and Volt forum posts and I am surprised that there has not been a recall. I hope that this issue is investigated same as the BECM issue.
