Recently reported VEHICLE SPEED CONTROL problems on 2008 Chevrolet Silverado 1500

The engine doesn't slow down imediatly after you release accelerator.. also the electric system comes on and off in motion... also sometimes speakers work and sometimes the don't ...in motion or not.. i lost control of the truck and hit a tree going about 40 mph no airbags were deployed...

The problem was not with the air bag, but the front switch that activates the air bags upon impact. when one or both fail the test when you turn the ignition on, it posts a message saying service the air bag system. there is lots of information regarding this on utube. apparently this is a common problem. i am an electrician and an electronics tech, i know that the air bags will not activate if the crash is on the side with a bad air bag. i had 2 brake light switches go out, at which time the person behind me,would have no idea, i was braking. the switch is a 2 part switch, one part controls the brake light, the other enables or disengages the cruise control system.

Rapid temporary loss of engine power, doorlocks cycling repeatedly, guages malfunctioning, radio shuts off and turns back on with no preset stations and showing 12:00 on the clock ,cruise control disengages. once vehicle is shut off, no guages nor lights work...as if there wasn't any battery in the vehicle. vehicle won't start until dome light is restored on via jumpstarting. cleaning battery connections and numerous ground wire connections gives short-lived relief from symtoms but problems ultimately return. chevy dealership diagnosis shows that ground wires have high resistance. online research shows that tens of thousands of other chevy owners are having similar to exact same problems, yet no recall has been issued. problem was "fixed" last year and has returned yet again.

Tl* the contact owns a 2008 chevrolet silverado 1500. the contact stated that while traveling 40 mph, the check engine and power train waring lights illuminated as the vehicle stalled. the contact also mentioned that a message stating that the engine power reduced had also appeared before the vehicle stalled. the contact had the vehicle towed to a dealer, who stated that the throttle body position sensor was defective and needed to be replaced. the vehicle was repaired but the failure recurred. the vehicle was returned to the dealer where the throttle body was cleaned and the computer was replaced but to no avail. the manufacturer was not contacted about the failure. the failure mileage was 110,000.

Passing a vehicle on county black top road,accelerated to initiate passing gear. accelerator stuck eng rpm at full speed. attempted to alleviate to no avail. attempted to shift to neutral but went into reverse also applied brakes. as a result there were 420 ft. of skid marks then right front wheel hit shoulder of road and vehicle went end over end landing in ditch on its top. the air bags did not deploy and there i was no recorded incidence on the data recorder. the vehicle was totaled by the insurance co. my concern is that this vehicle could be rebuilt and put back on the road as drivable vehicle since it had only 13,000 miles on it. if no cause for the malfunction can be determined there is a distinct possibility this could happen again with possible loss of life. updated 06/08/11 *bf *tr updated 10/21/11 *bf updated 1/18/2012 *ln updated 2/8/12 *cn updated 2/29/12 *cn *tr
