NHTSA Complaint #11573078 — 2017 CHEVROLET VOLT

Sudden failure of exhaust gas recirculation valve resulted in unexpected significant power loss on limited access highway and immediate loss of speed and acceleration. Driver was able to move to side of road with care and proceed in "limp home" mode. No warning lights activated prior to this event. Event could have been catastrophic if it occurred during heavy traffic conditions. Occupants could have been trapped in vehicle stuck in left or middle lane with no way to safely merge into oncoming high speed traffic. Car is available for inspection. GM dealer has provided the diagnosis of repair and suggested replacement of ERG valve and ERG valve cooler. This is a known defect and GM is unable to provide timely delivery of replacement parts. Waiting period of up to six months was predicted by GM dealer. Driver reports posted on internet forums reflect many Volt drivers reporting these same events and concerns.
