Similar problem with my Chevy Volt 2017. Only 38000 miles. Dead in middle of the road late night. Got it towed to Chevy dealer. They found transmission goes bad and need to be replaced. Good enough it’s covered under warranty. But I don’t have extended warranty and this makes me nervous. 38000 miles is not lot. I see too many red flags in here for Chevy Volt. I’m thinking they should buy it back and give me new car. If they don’t I might have to consult a lawyer and go from there. I can’t be driving this car on highway and suddenly car comes to a stop. This is how you get run over!
