2000 GMC Sierra recalls (8)
Structure › Body › Tailgate › Hinge and attachments
Certain pickup trucks have galvanized-braided-steel tailgate support cables used to support the tailgate in the full open (horizontal) position. Over time these cables can corrode and fracture when loads are applied to them.
Remedy: Dealers will replace the galvanized support cables with stainless steel support cables. In addition, dealers are to inspect the tailgate hinge and replace it, if necessary.
Service brakes, hydraulic › Antilock/traction control/electronic limited slip
Certain pickup trucks and sport utility vehicles May experience unwanted antilock brake system (ABS) activation. This condition is more likely to occur in environmentally corrosive areas.
Remedy: Dealers are to remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply rust inhibitor to the cleaned surface, grease the mounting surface, reinstall the wheel…
Parking brake
On certain pickup trucks equipped with manual transmissions and built with either pbr parking brake systems or trw parking brake systems, the parking brake friction linings May wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.

Structure › Body › Tailgate › Hinge and attachments
On certain pickup trucks and sport utility vehicles, the galvanized steel tailgate support cables that retain the tailgate in the full open (horizontal) position May corrode, weaken, and eventually fracture. If both cables fractured, the tailgate would suddenly drop and strike the top surface of the rear bumper.
Remedy: Dealers will replace the cables. Interim owner notification began on April 7, 20004. The recall began on September 24, 2004, when replacement parts were available, and will continue through October 29, 2004.
Air bags › Frontal › Sensor/control module-inactive
On certain pickup and utility trucks, some of these vehicles have an air bag sensing diagnostic module (sdm) which contains an anomaly that could result in the driver and passenger's air bag failing to deploy during certain frontal crashes.
Remedy: Dealers will recalibrate the sdm on the affected vehicles. Owner notification began August 28, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free…

Service brakes, hydraulic › Foundation components › Hoses, lines/piping, and fittings
Vehicle description: light duty pickup trucks and sport utility vehicles. Some of these vehicles have a clearance condition between the front right-hand brake pipe and the body cross sill that could decrease to the point of allowing contact during the life of the vehicle.
Remedy: Dealers will inspect the front right-hand brake pipe for wear. If there are signs of wear, this section of the brake pipe will be replaced with a new designed brake pipe section.
Service brakes, hydraulic › Antilock/traction control/electronic limited slip
Vehicle description: light duty pickup trucks equipped with 4-wheel disc brakes. Some of these vehicles have an antilock brake system (ABS) motor containing an out-of-specification spring clip. This clip could allow the motor bearing to become misaligned. If misalignment occurs, eventually the ABS would be non-functional.
Remedy: Dealers will replace the brake pressure module valve assembly.

While towing my boat I experienced brake failure. The pedal went to the floor with no pressure. Brake warning light did not come on. We were on a dirt road with no traffic and were able to stop without incident. After inspecting the brake lines a leak was found in one of the lines under the drivers side door before the line enters the brake modulator. All the lines are rusty and need to be replaced. I contacted the GMC dealer and although they have seen the problem before they are unaware of any safety problems with the brakes and that GM has no fix for the problem. They estimate the cost to replace the brake lines to be about $1200.
Vehicle: 2000 GMC Sierra ABS activates everyday at least once when coming to a stop at low speed such as a stop sign, parking space etc. This has happened for the last 6 months. Pavement is dry. I must quickly release the brake pedal and push it again firmly to stop. I've bumped another car and my garage because of this. A recall is out for this, GM recall # 05068, NHTSA # 05v37900 but my state, wisconsin, is not included. We use massive amounts of salt here. Do I have to run someone over first? I want this fixed.
Wheels & tires all 36 →
I have a 2000 GMC Sierra pickup with disc brakes on all four wheels. The parking brake is a horseshoe shaped brake shoe that is to grab a brake drum designed into the rear wheel rotor. I have used the parking brake about five times( exaggerated) in the life of my truck. When the brake failed to hold I thought nothing of it, as I rarely used it. Recently on an unrelated repair I had occasion to remove and inspect my rear rotors. The brake shoe for the parking brake repositioned itself and has been rubbing on the brake drum portion of the rotor causing it to wear the lining of the drum . Very little wear occurred to the parking brake shoe. The design of the shoe its position on the drum created a basin wear particles accumulated inside the worn area of the drum creating even faster wear to the surface. …
Firestone steeltex a/t, lt245/75r16, load range c, original equipment installed on 2000 GMC Sierra 1/2 ton, 4wd, pickup, purchased new by me, April 2000. On aug 14, 2004, approx 12:00noon, I was driving about 30mph , pulling a boat/trailer on a state maintained gravel road in lewis & clark county, mt., when the right front tire suddenly went flat with no sound of blow-out. After immediately stopping, I noticed the tire was comletely shredded. The entire outer sidewall had separated from the tread area by about 95%. The wheel was slightly bent. No other damage. No injuries. Nothing done to correct as yet.
Body & structure all 34 →
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. …
Tailgate strap on pass side of truck broke while tailgate was down and tailgate actually came off and damaged tailgate. This has happened 3 times after this. My 17 year old son drives this truck and 1 times this happened he was on a busy street and could not get to the side of the road and drug the tailgate about 1/4 of a mile before he could get out of traffic to reattach the tailgate. I have not had the tailgate repaired, because of the fear of this happening again and causing even more damage. I have at this point removed the tailgate from the truck until I can find a resoution for this problem.
