I own a 2000 gmc sierra 2500 4wd. I bought this truck new in june of 2000. In the past year, the corrosion issues are becoming overwhelming. Yesterday, a brake line blew out while driving. The brake pedal went to the floor as I approached a stop sign at an intersection with a state highway. Luckily, I got stopped as I was only going 25 MPH. I babied it to a local garage 1/4 mile away, and found brake fluid dripping out below the fuel tank area. After looking underneath, the mechanic noticed that most of the brake lines will need replaced because of rust. Goes along with the corrosion issue under the whole truck. I've already replaced the rear spring shackles on both sides, as one had rusted and broke in half while driving. This caused the leaf spring to slam up against underside of the bed, which dented and cracked the paint in the bed. I restore vehicles for a living, and I've seen cars from the 1940's that don't have this much rust on the underside. Come on gm!! It's great that the body looks like new and the engine runs great, but it doesn't do any good when the frame rots out from underneath!! And now the brake lines---glad I wasn't going 60 MPH with a loaded trailer when it blew!!

The frame on the truck is cracked several inches in a couple of places and rotted. It is very thin and I was told there was nothing solid to weld to and repair it. They said I would have to have the frame replaced. The truck has just turned 100000 miles. I have had it for six years and take excellent care of it. It runs great. The body is in excellent shape, there is one small hole in the driver side rocker panel I was going to repair in the near future ( I do not know if I will now bother). Other than that the body is near perfect. There is no rot in the floors or truck bed. The repair shop could not believe how bad the frame is when the truck looks so great. I have found a number of complaints on the internet similar to this, maybe if enough people speak up something will get done. Also, the anti lock brakes have not worked for some time now. I was told they get rust in the assembly and do not work right. I have also had several brake lines break and need to be replaced. I realize that brake lines do rust over time and do need to be replaced (they should be made from stainless steel from the factory) but the anti locks should work and a frame should not rot and crack as it has.

I experienced sudden brake failure in my driveway. There was no warning light,just the brake pedal going to the floor. My mechanic looked at the failed line and said all my lines and ABS unit were corroded and needed to be replaced. He also found my right rear spring hanger was rusted off and the spring was just resting on the body. The rear wheel brake backers plates are rusted off also, and the entire frame is very corroded. This is a huge repair bill that may exceed the value of the truck. This is not normal corrosion. I have lived in nh 55 yrs and have never had a vehicle rot like this. I have a 2000 volvo v70 with 147,000 miles on it with no issues. Obviously gm cheapened this truck up or bought defective parts. I have found hundreds of accounts on the internet identical to mine. This vehicle needs to be recalled before people are killed. I am thankful I was in my driveway and not highway or city driving at the time of the failure. Do the right thing and hold gm responsible. There would be no gm without our tax dollars and they need to make this right. Thank you

I purchased my vehicle used. The used car lot said all the clunking in the rear and vibration in the front was due to an aluminum drive shaft. I have been to numerous new auto dealers and no one can find the source. I have phoned gm and they say it is the first time they ever heard of clunking noise from the rear. Yet this problem is posted all over the internet. It may not cause a crash but it sure is irritating to hear over every little bump in the road.

Dt: the contact had recall 05v37900 repair work done on the anti lock brakes. Approximately one month later, while applying the brakes, he heard a loud grinding noise. The consumer was only going 8-10 MPH and the consumer traveled 200-300 feet before he was able to come to a stop. He took the vehicle to the dealership, and they stated the wheel bearings needed to be replaced. *ak updated 01/11/06.

I had the dealer do a schedule tire rotation, and on they way home I reached the speed of 40 MPH the truck started to shake like I was going over speed bumpers. This stopped but the front end still bounces when ever you go over a series of small bumps the whole front just shakes you have to use two hands to keep the vehicle in control, don't use the brake the pedal goes soft until you are out the rough road. I have had the tires replaced and but new rims on the vehicle. The bounce is still noticeable at speeds over 40, the road does not change the effect. The crowning of the road is not the problem. The dealer says the front is tight and can not duplicate my problem so they can not fix it. The service manger says I've lowered my front end this gmc sierra is totally oem exc for tire, and aftermarket dress.I had the truck aligned and the thrust angle was off so my son-inlaw and I did a thrust alignment first and the front end alignment. Also one of the upper control arm bolts was slightly loose, you could see the brown rusty powder around the bushing so this was loose for some time. I am a diesel mechanic so I know there is something wrong loose, or worn out that needs to be done to correct the problem, things do wear out and I do not mind paying for things to be done correctly

Consumer states based on the description in the owners manual, even if properly armed by following the instructions, the content theft - deterrent alarm system will only sound if the vehicle door is opened from within the vehicle after the manual lock has been utilized from the inside. Consumer feels that access has already been gained to the interior and therefore it is not necessary to unlock the manual lock, or open the door to steal the contents, thereby bypassing the alarm system altogether.
