NHTSA Complaint #11418808 — 2021 CHEVROLET BOLT EV

I recently purchased a 2021 Chevrolet Bolt EV (VIN [XXX]) with current mileage about 1800 on odometer. Two days ago my wife was driving on the 91 freeway going at normal highway speed when all of a sudden the car just decelerated ABRUPTLY to 20 mph with an error “propulsion power is reduced”. Two Ford F-150 trucks immediately behind her had to veer quickly around her (but this could’ve easily caused other accidents as well). She had to cross three lanes of traffic to get on to the shoulder while only able to drive at 20 mph. There was still 131 miles of battery charge left so it wasn’t because of low battery. Overall it was an EXTREMELY dangerous situation whenever a car decelerates abruptly without any warning especially while driving on freeway. I don’t know how she escaped unscathed and was not rear-ended, but she is traumatized by the entire incident. I want to report this so that you are aware of the situation since this poses a serious public safety concern that could have fatal ramifications. Yours truly [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
