NHTSA Complaint #11641599 — 2017 CHEVROLET VOLT

I was driving effortlessly down [XXX] between san francisco and santa cruz when suddenly i seemed to be losing power. Pressing the accelerator/gas pedal was not obtaining the usual result and I was going slower and slower by what felt like the second. I also noticed that it switched to gas although it said there were around 12 miles on the EV battery which was a sign that something was wrong. Fortunately there was a break and traffic was going at a speed which allowed me to make it across three lanes of traffic in just enough time for an alert posted on my dash saying something about loss of propulsion (not sure what it said exactly, because, i was driving!) and i coasted onto the shoulder, but barely. By that time it indicated that there were zero miles on the EV battery. (2 weeks prior I had been unable to start the parked car. I had the 12V battery replaced as the local mechanic where it was towed thought that that might be the cause.) I turned the car off and back on and when I tried to shift to D or R the dash stated "Return to P" AAA made us a priority tow as we were on a major thoroughfare. We were at risk, but thankfully we were relatively safe. I called GM to say that it seemed that the EV battery had died suddenly. I was advised to bring it to the dealer. I called the dealer and they quoted me the cost of replacing the EV battery. They mentioned nothing of National Highway Traffic Safety Administration investigation into the model year 2016 through 2019 Chevrolet Volt amid complaints about the hybrid’s battery energy control module, or BECM, some of the complaints indicating that drivers had little to no warning before the car lost operating power or entered reduced power mode, which was exactly what had happened to me. Nor did they mention a letter I discovered on line dated March 6,2024 re:Battery Energy Control Module Malfunction, and stating that they would be contacting customers. I was never contacted.
