Eight problems related to vehicle speed control have been reported for the 1997 Chevrolet Astro. The most recently reported issues are listed below.
Driven van about 30 miles stopped and when we started to take off van lurched foreward with aloud bang only does this between 1st and 2nd gears. When transmission is cold does not do this only when hot.
While traveling at highway speed of 70 mph with speed control engaged vehicle would not disengage speed control when applying brake pedal. Instead, it continued to accelerate. Driver was able to to shift into neutral, pull vehicle over , and turn off ignition switch. Vehicle taken to dealer for insepection. Feel free to provide any further details on this matter.
The van went from 60 mph to 85mph all by itself as if cruise was on but it wasnt the throttle just broke no warning no nothing the engine idled so high the brakes wouldnt work it took 10 min to get this thing to stop my brake was pushed to the floor and I was still going 45 mph it was lucky I was not in a residential area with traffic signals it was also lucky my 2 small children were not in the vehicle please look into this complain immediately.
While applying the brakes the vehicle started accelerating, causing an accident. Please provide further information.
Intermittently accelerator pedal will lock up/stick when applying pedal to go. Vehicle been in/out of dealer shop on five occasions, and problem still reoccurring.
Very fast idle, intrmittent, will accellerate vehicle beyond 60 mph with no gas pedal. Carried vehicle data recorder for 3 weeks, recorded 4 events. Dealer claims normal fast idle during deceleration as emission feature. My question, accel beyond 60mph with no pedal is not emission control, it is un-safe. It requires brakes to maintain 50mph on flat ground when the intermittent problem kicks in. I have had 3 years of dealer excuses, as they do not want to spend the money to fix even under extended 100. 000 mile waranty. They claim to not know what to do as there is no engine check light or stored codes. This has caused several driving concern incidents and 2 very close calls when it decides to kick in.
Throttle freezes. Must press extremely hard to move. Causes vehicle to jump. Estimated cost to repair $700 + labor cost.
