The throttle on my 2008 Vue XE stuck wide open today. I was accelerating hard from perhaps 35 mph and when I took my foot off the pedal around 40 or 45 the car kept accelerating. It basically ran away with me. I literally stood on the brake pedal and fought against the engine to force the car to slow down. I gradually brought the speed down this way over maybe five seconds (it felt like 20 seconds) until I reached perhaps 30 mph, whereupon I heard a sharp "clack," at which time the throttle closed. I was then able to bring the car back under control.
I assume that what happened is that the speed control somehow engaged with the throttle open and, for some reason, failed to disengage when I hit the brakes. I use the speed control all the time and I've never had any problems with it before. I believe the speed control was on at the time of the event, though it wasn't set (I had only just pulled away from a stoplight).
Anyone know of any precedents or have any other thoughts?
