NHTSA Complaint #11564574 — 2017 CHEVROLET VOLT

While driving the car in electric mode, a chime came on and flashed 'propulsion power is reduced', then it went into engine mode and the car decelerated quickly from posted 70mph speed to less than 40mph even though I pushed the accelerator pedal and reved the engine high. While in this low power driving mode, a warning came on saying the collision detection system was disabled. The concern is the person behind me had no warning since my brake lights did not come on. He sped around me with a bit of road rage. The problem temporarily goes away when you turn the ignition off and back on. I took it to the dealer and the said it needed a new EGR Cooler 4 hours labor $1500. Chevy Dealer pulled two codes P0401 Exhaust Gas Recirculation "A" Flow Insufficient Detected P1E00 Hybrid/EV Powertrain Control Module 2 I paid them the $165 diagnosis fee and got my car back and just plan to restart when it occurs. In another instance, I was pulling out from a parking lot into a busy road in electric mode and the car lost ALL power leaving me exposed in the line of traffic. Error messages on the dash said to 'service BECM' and 'shift to park'. The car was not drivable and had to be towed. Call me if you need any more information.
