I experienced a failure of the 12-volt battery. when this happens, the vehicle loses power, stalls, and then it looses all functions - cannot be even shifted into neutral to move it, cannot open rear doors. we couldn't even get in on a tow truck.
On 2018-07-26 at approximately 2325h, vehicle was being driven at ~70mph northbound on i-95, the maine turnpike. location was approximately 1/2 mile north of exit-32 (biddeford, me). road conditions were good, temperatures in the mid-70f, humid. the owner's wife was driving, with her husband in the passenger seat. at the time listed, the vehicle sounded a warning chime, and rapidly lost power from highway speeds (70 mi/hr). vehicle, with the exception of speed, was in control with brakes and steering, emergency flashers, and lights operating. vehicle driver information panel gave erratic and unreliable readings. alternately, the display showed: * warning icon on right hand side * message "shift into park" * range dropped from ~75 miles to zero * battery gauge would indicate 5% battery with a range of 70+ miles * regenerative battery icon showed a regen braking limit of <30kw (indicating battery full??) (page 116 chevrolet bolt user manual) after stopping vehicle was unresponsive to most controls. * intermittent inability to shift out of park * warnings to go into low-power mode * warning the "battery saver active" * warning for "high voltage charging system"
Stopped at store1/24/2018 when tried to restart, received transmission warning service sign, unable to move attempted 3 more times over 2 hours. finally it ran, but service transmission light stayed on. took to dealer. told it was a computer update that was needed, it hasn't happened since. reviewing chevy bolt forum, appparently i am not first owner service transmission warning has come on with car disabled it was stationary when service light first came on. had driven a mile after work day. had well over 50 percent battery charge left i was not given much info from dealer, just it had been resolved below is what is on mychevy.com site about issue repair from dealer print source dealer odometer reading 1,755 service location service information service #: 055209 service performed: engine elect concern note -------------------------------------------- told needed update on computer, transmission didnt work
The problem is that it is too easy to put the car in "park" by accident. on several occasions, i was trying to go from the "l" position to the "r" position. to do so requires you to press the side button and maneuver the shifter to the r position. on several occasions, while doing so, i inadvertently pushed the "p" button on top of the shifter resulting in the car ending in park when i wanted to reverse. this happens when i grabbed the shifter and press on the "p" button with my palm while trying to press the side button. most of the times it was not a big deal, i just tried again and then proceeded. however, on one occasion today, i was about to move into an intersection when a fast moving car appeared from a blind spot and i tried to quickly back-up and ended up in park instead. it took me a few seconds to realize what was going on and finally got it in reverse but it was potentially dangerous as i was in park in the intersection when i needed to move quickly out of the way.
