NHTSA Complaint #11579133 — 2016 CHEVROLET VOLT

The EGR valve failed part way through a long drive between cities while at interstate speeds. This caused the vehicle to produce a warning about reduced propulsion power (as well turn on the check engine light), and it became difficult to maintain speed with the surrounding traffic. I could maintain speed, but only in electric-mode, and my battery didn’t have enough energy to get me to my destination on that power alone. While in ICE mode (internal combustion engine mode) it would also quickly overheat. I reached my destination by repeatedly swapping between ICE and battery modes, to both extend my vehicle’s range as well as mitigate overheating. Upon arrival at a dealership, I was informed there’s a nation-wide shortage of EGR valves for my model of car. Despite escalating the issue with GM/Chevy’s support staff, they cannot locate an available EGR valve. This shortage has lasted for more than 4 months now and my car remains stuck in a distant city. This part is necessary to operate the vehicle safely, but they have not been producing enough of the part.
