 Fuel gauge works off and on mostly off. i purchased truck in spring of 2002 and problem started immediately after purchase , so i am guessing that the dealer knew of the problem just got lucky that i didn't notice till after the deal was done . have talked to several people with chevrolet trucks all years within 1999 through 2004 and all have had the same problem. and i have talked to several dealers and was told it would cost upwards of 600 hundred dollars to repair. sounds to me as there is definitely a problem and it isn't the car owner's that are at fault. there should be a recall on this problem. *nm

 The fuel gauge sending unit failed (i go by mileage to know if i need fuel or not). driver's side seat belt locks up when you go to look to change lanes (dealer couldn't reproduce the problem--so it's never been fixed). passenger seat belt locks up if you just lean forward to roll down the window (was told this was a mechanism for a baby seat--didn't think car seats were supposed to be in the front seat). right side daytime running lamp burned out a long time ago. abs module failed (had to pull the fuse so the pump wouldn't burn up) therefore the truck no longer has abs. driver's side front wheel hub failed due to lack of grease in the non-consumer maintainable bearing (the whole hub had to be replaced). the water pump has already failed (replaced that). the transmission is starting to slip here & there. the accelerator sticks causing you to have to jam on it in parking lots & other places where it's just not safe to be darting forward. this model year was just a bad year for gm. they need to fix these problems. this is the worst gm vehicle i've ever owned (and i've been a loyal gm customer all my driving years). *ak

 While having my brakes checked by my mechanic on my 1999 chevrolet silverado a problem was discovered with the gas tank straps. one strap had corroded completely through and was broken and the other strap was also corroded and just about ready to give away also. this left the gas tank hanging down at least 6 to 7 inches if not more. my mechanic has ordered new straps for the gas tank and temporarily wired the gas tank back up to prevent it from falling off the pickup truck while traveling down the highway. i went to the chevy dealership in town . they informed me that this was the first they have ever heard of this happening and there were no recalls that they were aware of. i than called gm to report the situation and file a complaint on it. i explained the entire situation to them including the mechanics name, business address and phone number that they could call for verification of the information. i was concerned that this situation could happen to someone driving down the highway with a full tank of gas unaware of the problem and have their gas tank fall off causing a fire or explosion on the road. when they asked me what i wanted to resolve the situation. i told the lady it would be nice to get reimbursed to have the problem fixed. she said that probably would not happen due to not having a chevy dealer fix the problem and that the vehicle had too many miles on it. i reemphasized the reason for making this call was a safety concern that i had about this possibly causing a serious accident for someone while traveling down the highway. i also stated that this was too new of a vehicle for this type of problem to occur regardless of mileage and that i felt the problem was due to a factory default. it would be great to get reimbursed for having this problem fixed but it would be greater if the information on this factory default got out and possibly saved someone's life. *jb

 Abs pump was energized when i started vehicle and continued to run even after i turned off the key. only way i was able to stop pump was by removing abs fuse, causing my abs system to no longer be active. chevrolet said this was a common problem. also fuel gauge will intermittently register no fuel after filling up and while riding even when the tank is full.*ak

 Bought a new 1999 chevy silverado and the strap on the gas tank has rusted off, which we fell this is a real safety factor, luck have it we were close to home, when you buy a brand new vehicle you don't expect the gas tank strap to rust off after just 6 1/2 half to 7 years. could of been very( dangerous) *jb
