Pulled in parking lot,put transmission in park,and engine began to increase in rpm to 2500-2600,I noticed driving home it seemed as if the cruise control was engaged (it was not). Applying the brake gently (would not correct)if brake was applied very firmly,it would finally let the rpm drop back to normal,.
My wife and I were driving on the freeway, with the cruise control on. At random the care kicked out on cruise and the speedometer was not working, we also had tire pressure warning, engine service warning, air bag warning and no odometer. We made it to the freeway exist, however when we went to accelerate the car barely moved. The engine would rev at high rpm's but would just crawl. We made it to our house (barely) and parked the car. The shift into park was very violent and made the care jump. With my foot on the brake I would shift from p to n, then n to r, then r to d and same order back to park. Each change was very violent. I turned the engine off, let it sit for about 1 minute, turned the car back on and the warning lights were gone and the odometer was back to normal. However, when I went to drive again the shift was still violent, I had not power (high rev and barely moved) and no speedometer. The car is currently in my driveway with that being the current state. I have done some research online and this appear to be a very common issue for these vehicles.
