Chevrolet Astro owners have reported 7 problems related to cruise control (under the vehicle speed control category).
Had cruise control engaged prior to entering a reduced speed area and it functioned normally. After departing the reduced speed area, I engaged the resume function and the vehicle accelerated past the set speed and kept speeding up. I was able to control the vehicle with brakes although they got very hot and smoked severely. Attempts to turn off the cruise control failed, as well as turning off and removing the keys from the ignition. After successfully stopping the vehicle, I continued attempts to disengage the cruise control but any attempt to start the engine resulted in immediate racing of the engine. I examined the owner's manual and discovered that fuse number 6 was labeled "cruise module, cruise control switch, electromechanical mirror". The fuse was removed but the engine raced upon attempting to start it. I then discovered that fuse number 18 was labeled "vcm-ign 3, vcm-brake, 4wal, cruise stepper motor signal". Upon removing this fuse, I was able to start the engine, and it remained in normal parameters. I did notice that the antilock light was on, but believe this is related to the vcm-brake label on the circuit breaker. I was then able to continue driving the vehicle home, and will be contacting the repair shop to disable/remove the cruise stepper motor, as I refuse to chance another unintended acceleration event.

The contact owns a 2000 Chevrolet Astro van. While the cruise control was set at speeds of 65 mph, the brake pedal was applied to disengage the cruise control. However, there was no response. The vehicle continued to abnormally accelerate while the brakes were applied. There was an extremely loud roaring noise coming from the engine with an increase in the rpms. The vehicle was rapidly approaching a traffic light and the gear was shifted into neutral position. The engine was turned off. The vehicle was coasted to a stop with very limited braking power. After several moments, the vehicle was able to restart. The vehicle was able to resume operation. The vehicle was taken to the dealer. The cpu (central processing unit) and optical wheel sensors were intermittently faulty which required replacement. The sensors were cleaned to correct the problem. The identical failure occurred on a separate occasion. The vehicle was taken back to the dealer that advised the replacement of the entire cpu. The vehicle has not been repaired. The failure and current mileages were 130,000. Updated 4/26/10

Without warning the cruise control will shut off when the consumer hits a bump. The consumer doesn't know when it's going to happen. The dealer was unwilling to troubleshoot, because the manufacturer will not reimburse them for the cost. The manufacturer will not pay to have test run on car. The consumer does not feel it's his place to pay.

Cruise control fails to disengage in neutral and reverse. Inadequate shift lever detent action results in inadvertant shifting into reverse. July 4, 2001:with cruise control engaged at 55 mph, operator mistakenly shifts from overdrive into neutral (thinking he is shifting from 3rd to overdrive). Engine begins to race when cruise control fails to disengage. While attempting to return to overdrive, operator shifts into lower gear due to inadequate detent action in shift lever. Engine races faster (cruise control still engaged). Operator shifts into reverse while attempting to locate overdrive due to inadequate detent action in shift lever. Cruise control remains engaged causing high speed reversal of drive wheels resulting in loss of vehicle control. Vehicle spins out and rolls on side. California highway patrol local report number 2001070020 (el dorado county).
