I just took my 2017 Bolt to the dealer on July 25 for the required battery condition monitoring firmware update.
The firmware update changed a number of my settings and zeroed my energy consumption history. Even more irritating is that every time I start the car, the charge rate limit resets form 12 Amps to 8 Amps. Now I have to remember to go to the energy screen and manually set the charge rate back to 12 Amps every time before I turn the car off.
The owner’s manual says the selection for charge rate limit is supposed to be retained for 30 days, and that is the way it worked before the new firmware was installed.
I am going to call the dealer Monday to see if the firmware can be downgraded back to the previous firmware version. I feel it is unacceptable to have to set the charge rate every single time the car is power cycled. When other family members use the car, they don’t always remember to check the charge rate before powering off and it ends up taking 50% longer to charge up.
I have also found the car does not respond to changing the charge rate in the My Chevrolet mobile app. The car keeps charging at 8 Amps regardless.
I am charging my car on a 120 Volt, 20 Amp rated outlet using the Chevy/Clipper Creek EVSE cord that was supplied with the car.
