| This investigation involves the general motors corporation (gm)throttle body (tb) utilized in model year (my) 1999-2002 silverado, sierra, tahoe, suburban, avalanche and yukon (subject vehicle(s)) with 4.8l, 5.3l, and 6.0l engines. the tb valve may intermittently stick in a closed position.in such a situation, an operator may apply additional accelerator pedal force to increase engine speed.the application of additional accelerator pedal force, to open a stuck throttle valve, may open the throttle valve more than intended and, in turn, accelerate the engine and vehicle more than intended and reasonably expected by the driver.on august 1, 2002, the office of defects investigation (odi), of the national highway traffic safety administration (nhtsa), opened this engineering analysis.the investigation revealed that two factors may cause the defect: 1) tb manufacturing process problems; and 2) accumulation of deposits (a pcv system by-product) on or around the tb throttle valve and bore.odi concludes that the tb performs in a defective manner after analyzing gm | ||||||

| Cruise control stopped working at 36,000 miles. thought it was a blown fuse so i had it looked at by the dealer service department at approx. 40,000 miles when i had it in for another problem. service center told me it was a bad chip and it would cost us $500.00 for a new one. they were not willing to work with us or contact gm to see if they might assist with the repair since it happened so close to the time our warranty expired. so we still have no cruise control on our $40,000 dollar vehicle! *nm | |||
