I picked up a new 2016 Volt about 3 weeks ago as my DD ( I commute from about 80 miles per day from DC suburbs to downtown Baltimore ) and things were fine till this Monday. I was on Md Rt 97 going about 65-70 mph ( Hold Mode / ICE ) had about 16 mile of battery left when a got a warning to shift to PARK and pull off road; did so but the car died fast 10 sec or so. Called in to Onstar and arranged for Police pull in to set up a warning for other cars and they got me a flatbed to the nearest dealer ( took about 35 minutes total). During the wait time the car electronics progressive died until the emergency blinked did not work. The car was brick by the time the flatbed got to my location.
1) Did a bit googling and this problem seems endemic to electric cars that use DC to DC transformers to charge their 12V battery:
Not sure why this is but these cars have a different duty cycle for the 12V than normal ICE cars ...
This seems very dangerous to me in that one has very little time to get off the road before shutdown..sort of like the key falling out of the ignition ..
2) My Volt is at the dealer being serviced.
Any other 2016/2017 Volts with same issues ?
As a note ..experienced car nut had 4 Corvettes & 2 BMW's .. 2 engineering degrees and retired from NASA now work in Bio IT .. Just seems bad engineering to have such a crap design ( Volt, Tesla, Leaf ) but maybe they all use the DC to DC converter..
