I feel the transmission is defective on this car. There are only 800+ miles on the car. In the morning I pulled the car out of the garage and the car did not feel smooth. I said that seemed awfully odd. I drove the car but nothing else happened. In the evening I parked the car in a parking lot up against a curb and a fence. I turned the engine off and placed it in park and I am positive about that. All of a sudden the car lurched forward jumped the curb knocked the fence down and stopped against a tree. Needless to say I was traumatized.

It was a dark cold (minus 18) morning driving to work. All of the sudden a warning came on. The engine power is reduced mode came on and I went from highway speed to 30 mph instantly. I barely got home. I was terrified and the car would hardly go. Very dangerous. After much research because no dealer could get us in ( three week wait) we figured out what was causing it. Code P0234 turbocharge overboost. The dealer said I was safe to drive it. Still reduced power. After one week it warmed up to 17 degrees and the check engine light came off. I still have reduced engine power. New turbocharge feature for the 1.5 lt equinox. This should have been tested in cold climates. We regularly have 20 below temps and it’s a brand name car. I see a recall coming.
