He said it would lose power pulling a big hill in snow and the car just wouldn't make it, he'd have to turn around go back down and try again. He hated the car so much that winter he said he always left the keys in it hoping someone would steal it Lol! We have long steep grades here in the Catskill Mountains.Did he put REAL winter tires on it?
I thought he said it was something to do with the motor taking over the electric too late but I was just looking them up, it looks like they had a problem with mountains in snow where the traction control would actually decelerate the motor/loose power. I don't know if this is something they have addressed and fixed now.
