| EA02015 | GENERAL MOTORS CORP. | 08/01/2002 | 01/12/2004 | THROTTLE STICKING CLOSED | ||
| 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 | ||||||

| I received a recall in 2005 for the speed sensor at which time i had it fixed. around 2008 it started to happen again and the dealership on good faith fixed it for nothing. 2009 it started again and we had to pay around 500 to fix it. now it is 2011 and the problem is starting again. during this time we have had problems coming toa complete halt and almost crashing into another vehicle. i don't make a lot of money and need this vehicle to get to and from work. i do not drive this vehicle off road or long distance just around town. for how old it is i have low milage and i feel ifsomething is recalled it should be fixed the first time. | |||

| I own a 2002 chevy silverado k-1500 with 64,000 miles. last week i was pulling into a parking space at 2-3 mph, and all of a sudden my brakes failed ( pedal to the floor) and it felt like the truck accelerated (my foot was off the gas pedal. i ran into a brick wall, cracking some plastic on the front bumper, and denting the bumper itself. luckily, i hit the brick wall with the front tow hook. the next day i took my truck to stanley chevrolet and had them look for any problems. the truck was taken there earlier in the fall, to correct the abs recall. stanley, could not find any problem. i would also like to submit that my emergency brake system is completely worn out. which is odd since i have never used them. *nm | |||

| I have a 2002 silverado chevrolet 1500 short bed (~50k mi) with a sticking throttle body. i have approached eldorado chevrolet twice about having the problem remedied. they have told me that cleaning the throttle body is a routine maintenance issue- and that it is my responsibility to take care of this. the thing is, the owner's manual does not give a mileage or time frame in which this item should be inspected and/ or cleaned!! i've read numerous consumer reports and testimonials from other chevy owners complaining of the same problem. gm customer service tells me that additives in the gasoline in my area (north texas) cause carbon to build up in the throttle body causing the gas pedal to stick. i have several friends who live in my area and who own chevrolet pickups. none of them have a problem with their gas pedal sticking!! this is a serious problem for which gm needs to take responsibility! if i do clean the throttle body, the problem is likely to reoccur. i guess gm will suggest i lobby to have the texas oil producers change the chemical makeup of their petroleum products!! i hope more people experiencing this problem come forward- i feel this should definitely be a recall issue. thank you, robert laughon. *nm | |||
