I've had the sensor to my tire monitor replaced 3 times and it continues to come on and cause my tire light to come on, although my tires are fine. It continues to stall when I'm going into 1st gear or changing gears on the highway. When accelerating my pedal will shake.
It's throwing code po742. When I come to a stop and try to go it hesitates and almost causes accidents. I've done research and my vehicle is not the only one of these cars that have the same problems, so it's definitely a defect , considering it has 120k miles on it.
