| 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 | ||||||

| The accelerator pedal on the pickup has and still does stick when trying to accelerate slighly/slowly forward or backward as in parallel parking. the problem is worse in hot weather. the dealer, during warranty period, told me they found no defect and knew of no defect. i left it go. my friend who owns a saturn sedan told me he has the same problem with the acclerator sticking during small maneuvers. i have just read that there are twelve complaints similar to my issue that have been reported to your agency. i am reporting the same at present thoughthe problem has been ongong for ten years. it makes close parking difficult and i try to avoid the situation because of such. i have almost crashed many times because of the amount of overpressure to the accelerator to make the truck move. | |||

| I just bought a 2000 gmc sierra 1500 pickup with the 5.3 liter engine. the throttle sticks when you start off in it from a stopped position. the accelerator has a tight spot in it when you first press on it. this can be very dangerous if it sticks too much when it breaks loose the truck will go forward real quick and you could hit somebody or something. someone told me that the butterfly had carbon built up on it and it needed cleaning. i called a gm dealer and talked to the service manager and he said it was reported before and he would clean the throttle valve for $90.00. i think this should be covered by the manufacturer and besides it will happen again when carbon builds up on it again. a permanent fix needs to be put in place as a recall item i think. *jb | |||

| The accelerator pedal has been sticking intermittently for the past 5 months. it takes extra effort to move the pedal from the neutral (rest) position in order to accelerate. this condition is intermittent. currently, the sticking is barely noticeable. other times, it is very apparent. note: i know of two other gmc sierra and chevy silverado ownes at my place of employment. both have had this problem (both are year 1999 vehicles, one 2wd, the other 4wd). my vehicle is a 2wd regualr cab short bed pickup. mr | |||

| Accelerator pedal sticks in a closed position, and then it will suddenly take off, which can cause a loss of vehicle control. dealer claims defect is due to a dirty throttle body. throttle body should be cleaned every 15,000 miles. consumer is upset because this information is not stated in owner's manual.*ak *slc | |||

| On 12/13/99 when slowing down to make a left turn, the tourque converter locked up and stalled the truck in middle of traffic while crossing the left lane. with difficulty, truned the wheel back to the right and pull off the road and shifted into park and restarted the truck. luckly there was very little on coming traffic. on 2/11/00 while coming into a rolling right hand turn and going about 15 mph, i started to brake and the tourque converted again locked up and the engine stalled. again with difficulty i was able to steer into the corner and make the corner. as the truck was free rolling it just started itself and it contiuned on, almost crached into two cars waiting at the stop sign. if my wife was driving there would have been a collision. in october when waiting for a traffic light to change, i accellerated and truck didn't move. i stepped on the brake shifted to park and then back to drive and it finally went into gear and moved. have been back to the dealer twice with tourque converter concerns with no solutions. gm has a transmission problem with there 4l60e transmissions. my 1998 gmc jimmy has been replaced at 19000 miles. am very worried that this will happen at any time when not ready and an accedent will happen. *ak | |||

| The gas pedal sticks regularly. it sticks when the vehicle is at a stand still. it is very hard to press the pedal at times. when i do push the pedal it takes a lot of pressure to get it pushed in and the vehicle then darts forward very quickly. when in a tight space this can be quite dangerous as i am unable to control it. 8nlm | |||

| My accelerator pedal has been sticking for quite some time. it was very subtle at first and i didn't give it much thought. i had intended to mention it to my dealer but didn't because i began having problems with not being able to start my truck. after about five or six trips to the dealer they finally installed a new computer component that had been recalled and fixed the problem. now my warranty is up and the gas pedal seems to stick more often. i can live with it while traveling because it doesn't stick at a current speed that i am driving at; it sticks when i want to start out or accelerate. my concern is that recently when i started the truck it stuck to the point that when i tried to depress it stuck and then freed to where i darted out of my parking spot. this was scary and i decided i had better report it to the dealer. i had a service completed on may 23, 02 and raised my concerns with shawn d. in the service dept. and another gentleman (name unknown). the unknown party asked me if my truck was still under warranty and i told him no. i also pointed out that this should be a recall item as it could be a major accident waiting to happen. he said they were aware of the problem and that it was a carbon buildup that took about an hour to repair. he said gm hasn't decided to recall it at this point. i don't feel that i should have to pay for a potential safety hazard that was a manufacturer's boo boo. i am surprised that a company that has such wonderful marketing ads stressing professional service and pride would overlook a problem that could prove extremely costly to them in the future. i hope you can be of some assistance to me.*aki | |||

| Throttle becomes sticky when closed. as a result extra force is required on the accelerator when initialy depressed. this is an extremly dangerous situation especialy in parking lots or other tight, highly populated areas since extra force is required on the accelerator to break it free once it does break free the vehicle can lunge/lurch foreward uncontroled. this situation makes smooth throttle control unobtainable. the problem seems to get worse with higher ambient temperatures as i assume the throttle plate expands when hot and binds in the throttle body. cleaning the throttle body provides relief for a very short period. i have read about this problem on several internet message boards and believe that gm offers an updated throttle body to correct this problem. due to the extreem safety hazzard i feel that gm is neglegent in not offering to correct this problem at their cost, as gm does seem to be aware of the deficiency.*ak | |||

| We purchased a used 2000 gmc and within a month experienced experienced throttle sticking closed so severe you could not move the vehicle. then if you applied a lot of pressure it would lurch forward. we took it in after a couple of months to a local gmc dealer and they said it was the throttle body and it was warped and would need to be replaced. they had no explanation why it would have become warped. we paid 643.00. when we picked up the vehicle my wife went online to research if there were any problems and came across a reference to a tsb so we checked out nhtsa and under defects was listed the investigation that is still open about the throttle body( ea02-015) . we were very upset and took in copies of the tsb and spoke to the service manager. on our receipt was listed another tsb #00-06-04-007b as to why they replaced it. but with a charge. we felt they should had disclosed this problem and that odi was investigating it . the service manager said he would call gmc and we received a call the next day that gmc would be sending us a check for 400 to cover the part. that seems fair but we definately feel this is a safety issue. had we not been older drivers and very cautious we could have been involved in an accident. it could have stuck open as well as closed. *ak | |||
