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 |

Since we've had this truck, the acelerator sticks and you have to press it hard to get the vehicle to move, then it races for a second and jumps forward or reverse. this happens when it is at a complete stop, when you're starting off. it is dangerous in traffic situations, such as frequent stop & go traffic, and when you're trying to maneuver in tight spaces, such as parking. i'm sure that it also causes excess fuel consumption. *tr | |||

Many problems: 4 wheel drive sensor, front end suspension, parking brake, service brakes, anti-lock brakes, speed sensors, radio, center console, engine noise rapping when starting, tailgate cables, anti-theft sensor, and now the battery voltage gauge needle excess dropping when stopping, engine idling to low when stopping. dealer says problem is normal. let's test drive a new truck and show me it is normal. this truck is a lemon in my eyes!*jb | |||

The transmission violently shifts into gear upon acceleration from a stop or slow speed. this problem has occurred as many as ten times since the original date of purchase. on may 4th it occured so violently that the passenger in the rear hit his head on the rear window. in this incident the shift was so hard the rear wheels left the ground(all 4) and then the truck lurched forward. this is a serious defect that could caused harm to those inside the truck and could harm other drivers or pedestrians. the truck seems to go to a neutral operation even though you are in drive then when the rpms icrease to above 2,000 it suddenly shifts. i have taken the truck to the dealer 5 times and recently completed arbitration to take the truck back. the gmc represenitive claimed that this was normal for a heavy duty transmission such as the allison. the best discription of the problem is it feels as if you have been hit from the rear by another vehicle at 15-20 mph. *ak | |||

The transmission has a problem that causes the truck to lurch forward just after coming to a complete stop. the lurch can be quite strong causing the vehicle to jump forward in excess of a foot. the lurch occurs at unpredictable times and without warning. the best description i can offer is that it feals as if the vehicle has been hit in the rear by another vehicle. it has occured at least 6 times on various occasions.*ak | |||

The throttle stuck. it was not a continuous problem. after vehicle had been driven and would be parked,consumer restarted vehicle and had to apply more pressure than usual in order to have accelerator pedal released. when this happened vehicle jumped or would take off on its own. vehicle was under warranty which the dealership/manufacturer would not honor. *ak | |||
