Week prior battery would not start. Tire pressure keeps coming on even new tires. Then serviced for the 30 thousand check and two days later. Driving on freeway was going 65 and car decelerated to under 50. Kept doing this and I took off cruise control and pedal all the way to floor and it would not go faster then 50. Thought I was going to get rear ended. Wrench came on screen. Which means service maintenance, then drove 15 miles to get to where I was going, still not shifting right or keeping speed. Got to place and before I parked tire pressure light came on. Parked and stayed for about 6 hours got in car drove and shifting still and issue but kept speed, the wrench icon was then off, tire pressure still on. i was alone and scared to death thought I would be killed. Will take back in this week, but sure will be told nothing wrong since wrench turned off. And it will be close to 30,000 miles. So they won't find out why since close to warranty.
