NHTSA Complaint #11515787 — 2016 CHEVROLET VOLT

Our 2016 Volt was cruising at 65 mph on a major interstate highway (HOLD mode) when out of nowhere the check engine light came on followed by a warning message "Propulsion power reduced." We managed to pull off the highway, but a few minutes later navigating on local roads, we received another message that the engine had overheated and was shutting off. Fortunately, there was a chevy dealer only several miles away, and we made it there slowly under EV mode. They later traced the problem to a failed exhaust gas recirculation (ERG) valve. It was replaced under warranty. The whole experience was terrifying. We also own a 2017 Volt, and now we are afraid that it could also experience the same problem without warning.
