Tried to stop before a red sign on a city street, the car accelerated on its own, passed the red light and run at about 60 mph on a 35 mph street for about half a mile and then stopped by itself. Pressing the brakes and even putting it on park did not help. I am lucky to be alive with my two passengers, and lucky not to kill anybody or cause property damage.

Started stalling at idle, then just shuttered and stalled while moving, 28882. Moles. Had crank, air would run but would not restart. Dealer had it for a week and told me was battery. Weird because it had crank but wouldnt start. Had it back and immediately notice did not accelerate right, very hesitant and at idle nearly stalled, felt like was "missing". A few days later it stalled twice while at a stop light on busy street right in front of dealership! It stalled again 2 days later so back to dealership. No codes of course. They said drove it for miles and couldn't duplicate. They actually drove it for 9 miles! Gave me loaner and will keep it over weekend. Afraid someone is gonna run into back at a light when it stalls. Something is wrong and noone can figure it out.
Plastic valve cover warped at/before 83809 miles, leading to vacuum leak/loss of power.
Driving car locks up check engine light comes on says check power steering, we aimed to side of the shoulder car dies wouldn't start. We had to wait on side of a interstate for 3 hours to get a tow truck, very dangerous
