Consumer states the engine speed does not return to idle when the accelerator is released, the vehicle will go 20 to 30 miles per hour on its own, the problem is more persistant when the weather is warm/hot, consumer reported the problem on several occasions only to be told there were no codes stored, finally the manager of the dealership drove the vehicle and determined the problem was a bad idle solenoid, they replaced it and that fixed the problem for about a year, the problem has reoccured and the vehicle is now out of warranty and it continues to run about 1000 RPM for a time after releasing from the accelerator.

This was dangerous because when accelerating and taking foot off of gas pedal vehicle did not slowdown, it stayed right at that speed.
