2004 Chevrolet Silverado: adaptive cruise control problems

Filed Aug 27, 2014 · Acceleration · 60,000 miles · AZ

Driving through utah at posted speed limit of 75 with cruise control on, the speedometer suddenly started to indicate a deceleration from cruises speed to 30 MPH. My vehicle did not physically slow as evidenced by my GPS which continued to show actual speed of 75 MPH. Disengaging the cruise control did slow the vehicle when the actual speeds were 50+/- MPH than indicated on speedometer. Stopping my vehicle and turning the ignition off apparently reset something? Immediately restarting my pickup seemed to remedy the problem for a short period of time. This speedometer problem has persisted for over one year requiring the continual use of GPS to confirm my actual speeds. I have a significant cause of concern when indicated speeds are significantly faster than indicated. I contacted gm dealership, only to be told they have no idea of the problem and would not confirm the continual problem. In conjunction with the speedometer problem I'm also experiencing problems with the the fuel tank levels. Gauges indicate 1/2 tank, however when fueled at that level the tank required nearly 20 gallons of fuel to full. Again the gm dealership was not concerned with the safety problem. Online searches of similar problem have indicated many chevrolet silverados are experiencing similar safety problems.

Speedometer has been "jerky" for a month or so. This morning on my commute I set my cruise-control at 65 MPH, when I checked my speed again the speedometer was reading 50 MPH. I did not reset the cruise control.

Instrument cluster on 2004 chevrolet 2500 hd starts going out and the speedometer and tachometer cannot be depended on. When this is happening and you have the cruise control on who knows how fast you are really going. I feel there should be a recall since chevy has them designed to where they generally go out just as the warranty goes out. Why should we wait until this causes a wreck.

While driving on I-75 north comming from florida after crossing the georgia state line driver made stop at the rest area,when I resumed trip the cruise control failed to engage,a few miles later in heavy traffic the cruise control engaged on it's own. *ak almost causing a accident,this truck has had nothing but problems since the day it was bought,anymore problems this truck will be parked and tiltled only for my safty and the safty of others on the road.seems to me after 100 years of auto building general motors could get it right,oh by the way the local dealer said he could not find anything wrong with the cruise control,I have no doubt if this had been a cash fex instead of a warrenty problem they would have found the problem.

Cruise control surges going down hill (accel,decel,accel,decel) appears that computer "gain" and "deadband" are incorrect. Dealer says that gm currently does not have a solution to this problem.
