NHTSA Complaint #11534578 — 2017 CHEVROLET VOLT

When the EV charge runs out and car turns on gas engine. Gas engine will run for a few minutes and then turn off with an error message on dashboard. Car will only drive safely for as long as you have EV power, which is a problem since the gas engine is used when the EV power runs out. Mine failed on an interstate, but I made it to a safe place to stop only because I had a tiny bit of EV charge left due to my practice of using hold mode to save some battery power on long interstate drives. Service reported back that it is a faulty EGR valve and I am waiting to find out if they can even get the part in stock. GM is not adequately stocking these EGR valves. The failure rate from known manufacturing/design defects is higher than the rate that they restock them. These cars are not street legal when the EGR valve fails due to their inability to pass emissions testing since the EGR failure causes the service engine soon light to be on. An owner cannot renew the registration to legally drive the vehicle once the EGR valve fails, the whole car is undriveable without the part being available.
