2019 Chevrolet Bolt EV transmission complaints

Filed Feb 14, 2020 · Transmission · 10,000 miles · CA

I have a 2019 bolt EV (mileage approximately 10k) that automatically shifted gear to "park" mode from the "l" mode and slowed to an almost stop while I was on the highway at rush hour driving approximately 65 mi/hr. I was able to safely steer the car to a median and call on star after repeatedly shutting power off and back on again. I was able to connect with on star for live diagnostics showing a failure in the hybrid control processor (p0a78). I arranged for the vehicle to be towed to the nearest dealership and has been under repair for the past two weeks. Gm sent the dealer a "control module" as replacement but this didn't fix the problem. Recently, the dealer called to inform me that the transmission will be replaced but neither the dealer or gm provided a root cause for the failure. Gm has not provided any indication whether this is an isolated or known issue, however, I gathered from public forums that other bolt EV owners have experienced somewhat similar unexpected shifts in gear to park.*dt

Got brand new vehicle on sept 7th. On sept. 8th suffered loss of propulsion and inability to change gears. After driving for 20 minutes (50%+ charged) we reached our destination. I attempted to shift the vehicle to r in order to parallel park, however the vehicle was stuck with a message showing an inability to shift. We tried multiple times toggling the car on/off. After leaving for 10 minutes and trying again it worked, however with a service engine light on. We continued to the grocery store. After leaving the grocery store and driving 10 minutes we suddenly while moving got a 'loss of propulsion" message. Pressing the acceleration pedal did not move the vehicle. We struggled to navigate to the side of the road after losing total power. We tried again turning the vehicle on/off being greated with inability to shift message. Eventually after 15 minutes it turned on and luckily we were blocks from a chevy dealer. This was quite traumatic to go through with my mother-in-law and pregnant wife.
