2008 Lincoln MKX Vehicle speed control Problems

“Kicked on cruise control at seventy. Rpm's shot from 2 thousand to eight thousand and car accelerated to eighty miles an hour. All we doing was holding the steering wheel. We have taken it back to the dealer twice since we purchased two months ago and they have informed us both times that they can find nothing wrong with the vehicle...”

“Yesterday (11/05/2016), I was going to go to the store. The car started fine and ran fine as I backed it out of our driveway, but when I went down the street in front of our neighbors house, it suddenly felt like it shifted into a lower gear. I turned the corner next to my neighbors house and proceeded down a hill that's there, but the car still would only go very slowly. When I got down the hill, I stopped at a stop sign and when I stepped on the gas it suddenly started to run fine. …”

“Driving down the highway and transmission shift to low by itself. It almost caused me to get it. The ptu is leaking transmission fluid. Youneverknow when it is low. This car had this problem since it was manufactured and they never fixed the problem. It needs to be fixed and needs a heat shield between the ptu and the engine to keep it from leaking and causing dangerous situations on the road. The car smokes so bad that it looks like it is on fire. Scared to drive because I never know what will happen if the fluid is low. You can see the leak from the ptu under the car. …”

“About every few weeks, upon driving from a stopped position, it seems like the car is stuck in first gear or in low gear- it accelerates upon stepping on pedal, however the car is just crawling along and not picking up speed at all. Consequently, I have to stop the car and put it in park and then back in drive, once I do this it works normal again. On other occasions I feel a hard kick when I put the car out of drive and back into drive. This is very dangerous if I happen to be pulling into a busy intersection and I would have to come to a complete stop to get this car going again.”

“Vehicle (08 Lincoln MKX) was cruising at 35mph going down slight incline when suddenly vehicle started accelerating on its own at ~3,500rpm. As the vehicle was going down hill at 35mph in a 30mph zone with no other vehicles in sight, neither gas nor brakes were applied as there was no need. Foot was off both pedals until I realized that the car was accelerating on its own at an uncontrollable rate and it was then that I applied the brakes. Car continued to accelerate as the brakes were being applied. Acceleration lasted approximately ten seconds and then vehicle reverted back to normal. …”
