NHTSA Complaint #11632822 — 2020 CHEVROLET BOLT EV

While traveling at highway speeds, my Chevrolet Bolt (2020 with 20K miles) made a clunking noise followed by a loss of speed. The clunking noise had previously been reported to the dealer, but they were not able to identify any issues at the time. During this incident, however, the car ultimately lost all speed, forcing me to pull over to the side of the highway. This sudden loss of propulsion posed a significant risk to my safety and the safety of other motorists, not only due to the loss of power, but because it happened at an interchange where multiple highways are connecting. I was left on the side of the road waiting for a tow because the car was inoperable. Prior to this sudden failure, there were no warning lamps, messages, or other symptoms, aside from the previously reported clunking noise. After this incident, the dealer diagnosed the issue as the one listed in the technical service bulletin, which states that "the terminals may not have been perfectly aligned during installation at the vehicle assembly plant." Unfortunately, this issue was not covered under the warranty and currently this problem is not a recall item for the Chevrolet Bolt.
