I just bought this car from a used car dealer with 108k, got way overcharged because I don't have any credit. The second day that I had the car I was taking my baby to day care. The car shut off in the middle of the highway and we almost got hit. The engine fail safe mode came on. The car did this again on the way home. Took it back to the dealer and they had the throttle body replaced. I just got the car back today and it did it again! I'm about to loose it!.
