Brand new car suddenly stalled while driving - still had about 10 ev miles left and a full tank of gas when it happened, traveling straight at around 45mph. Messages displayed on dash telling me "propulsion power reduced to 0" and "shift to park", giving me about 30 seconds to pull over before it completely stopped. Restarted car several times, but "initializing wait to shift" and "propulsion power reduced" messages displayed, as well as check engine light. Car would not shift out of park, even to neutral. Luckily I was on a quiet city street at night and not on the freeway, as this could have been extremely dangerous. On star service had me towed to dealership, whose service department said it was a faulty part in the electric engine charging module. They will replace the part. However, since having this issue I have read of countless other similar situations on previous Volt models, with sudden stalling and "propulsion power reduced" messages. It is so common there is a pinned message about it on the Volt internet forums, and I have read several previous NHTSA complaints. It seems all too common and I believe is something that should be investigated as it could cause serious injury or death depending on where/when it happens. If it was a known fault on previous Volt models it should have been fixed in the 2019 version.
