I was driving back home from the store Friday night and my wheels start squeaking and increasingly became hard to then the wheel whenever I turned. When I got home tried to park the wheels locked up and I couldn't turn the wheels anymore. Diver the car again Monday it was fine until I was my way home again the wheels locked up, car wouldn't accelerate part 2nd gear, then I wasn't able to reverse and my engineer light came on. I just bought the car 5 months ago from a dealership. No I don't have a warranty and there is 86927 miles on it. No accidents whatsoever. I recently found out that this vehicle is known to have transmission failure.
