NHTSA Complaint #11617333 — 2018 CHEVROLET VOLT

On 9/18/24 I was driving my Chevrolet 2018 Volt on a freeway, traveling at approximately 55 mph while starting to exit the freeway. In the middle of fast-moving traffic, on the freeway offramp and starting to decelerate, the car suddenly displayed a message saying "Propulsion Power is Reduced." A micro-second later, the displayed message changed to read "Action Required: Shift to Park" and in that moment I lost control of the car's powertrain. I continued to break, coming to a slow stop in the middle lane of a multi-lane offramp, with other cars speeding past and around me. I attempted to power the car down and reboot it, moving the gear shift into "Park" position as instructed, but nothing changed. The car remained totally inoperable. I was on a slight decline and noticed the car moving forward pulled by gravity, so I steered the car to the farthest right of the offramp/parallel street, where I put my hazard signals on and requested the car be towed to a mechanic. I was endangered because the car lost entire propulsion while in the middle of fast-moving freeway traffic, and fellow motorists were endangered as well. I have learned that this same behavior occurs routinely with 2nd generation Volts; that there is a special bulletin related to the car's BCEM *and* a related class-action lawsuit posed against GM/Chevrolet. I requested Chevrolet take preemptive action to repair the BCEM, as I am fearful the issue will repeat and cause additional danger to myself and fellow motorists, but Chevrolet says they cannot repair the part until it is diagnosed as defective... which will occur when/if the part fails again, and I'm already in danger.
