Cruise Control problems of the 2001 Dodge Durango

Bought vehicle about 1 month ago and my horn and cruise control were working at time of purchase. Took car home and went out the next day and found out that horn didn't work after almost getting into and accident, so now I no longer have a horn or cruise control on my car.

The cruise control in my 2001 Dodge Durango accelerates and brakes constantly. Since it is out of warranty, I will have to pay for repairs since there was not a recall that I am aware of.

Very frustrating intermittent problem with rpm fluctuating up and down when I have not, and I repeat not, moved my foot down onto the accelerator. Happens more often when cruise control is in use. Service engine light comes on then disappears. Very scary, have almost crashed a few times when vehicle accelerates rapidly. Worst thing is the problem can't always be reproduced for anyone to believe me!!!!!.

S10 appropriate handling re Toyota throttle control problem owner of a 2001 Dodge Durango slt experience similar problem. The consumer stated he experienced a series of un-commanded rpm surges while in and out of cruise control. The surge would be as much as 800 rpm and almost resulted in an accident more than once. It took the dealer five service calls to finally discover the problem. The discovery happened only after the check engine light stayed on long enough for the service department to download an error code from the powertrain control module (pcm). The surge was caused by a failing and/or failed throttle position sensor (tps). The tps recently failed again, but this time the surges did not exceed 300 rpm before the source of the failure was confirmed. As in the initial failure, and even though the tps was suspect, the service department was not able to identify the problem until the check engine light came on. The consumer believed the pcm was not programmed to detect a failing tps. As a result, the pcm continued to react to spurious signals from the tps, resulting in un-commanded rpm increase which continued until a hard failure of the tps was detected.
