VEHICLE SPEED CONTROL
08/04/2008
 I have 2003 suburban 1500, that keeps getting a error message reduce engine power. the vehicle will all of sudden while driving, reduce speed and i can't accelerate above 25-30mph. i will have to pull over and turn car off for 10-15 seconds before it resets, however it will continue to happen over and over again! it is very scary and dangerous when i have my kids or my wife drive it because you never know when the car will have this happen. strangely, when we drive on the highway we can use the cruise control feature when we reach 25mph and use the cruise control to accelerate that way with minimal occurances. i have taken the car to 2 chevy dealers and 3 mechanics nither can tell us whats wrong! this is frustrating because we only have on car, and we know this a safety hazard and extremly dangerous and somebody has to look into this! i only hope someone who reads these complaints has the power to help me and everyone with this problem.

 2003 chevy z71 sub speed odometer is not working correctly. will work one day and be off by more than 80mph the same day. gm will not do anything to assist and can lead to accident as well as tickets as we have no idea of what speed we are traveling. *tr

 Revving of engine to point of screeching tires. sometimes feeling of being in neutral for a second then clunk in tranny/rear end? acts as engagement of cruise control increasing speed, not able to disengage by hitting brake. computer did not show anything. next time putter locked out tech's. puter replaced. worked good for two weeks. engine revved, hit patch of ice, totaled out z-71. thank god, no injuries. fighting it for appx 16000 miles. 72000 to 88000. *tr

 My 2003 chevy suburban speed odometer is malfunctioning. when at a complete stop it reads 30 mph and when driving on the highway it will go to 120mph and sometimes past that. vehicle just hit 50000 miles. this is very dangerous safey problem that can lead to accidents and speeding tickets caused by a known malfunction in gm vehicles. the cost of repairing this problem is very expensive and should not be an out of pocket expense.*cn

 I have a 2003 chevreolet suburban that has a faulty, racing speedometer. i just saw a news report on cbs television about this problem. my dealer told me it was just my car. now i see many cars may have the same problem. the speedometer randomly races to a very high and incorrect speed.*jb

 Speedometer quits registering speed of vehicle at times, the odometer continues to work. next time driving vehicle speedometer works. dealer said this is a very common occurrence and eventually the speedometer will quit and i will have to buy a new one. i do feel that a non working speedometer is a safety issue. *jb
