Risk and remedy
Risk
A lap portion of the seat belt routing that IS not low and snug on the hips can allow the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury.
Remedy
Dealers will cut open the guide loop, remove a portion of the loop, and then the remaining two sides should be folded over and secured with a retainer free of charge. the recall began on july 21, 2005. owners may contact cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, or hummer at 1-800-732-5493.

Risk and remedy
Risk
If a separation occurred and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. the loss of fluid would cause increased steering and braking effort and a crash may occur without prior warning.
Remedy
Dealers will test the hydro-boost assembly for functional operation of the two-function valve. if the hydro-boost assembly fails the test, dealers will replace the assembly free of charge. The recall began on march 23, 2005. owners may contact chevrolet at 1-800-630-2438, GMC trucks at 1-866-996-9463 and hummer at 1-800-732-5493.
Certain extended and regular cab pickup trucks and cargo vans converted to compressed natural gas (CNG) fail to conform to the requirements of federal motor vehicle safety standard no. 225, 'child restraint anchorage systems.' these vehicles have one seating position, the center rear seat, equipped with child restraint lower anchorages.
Risk and remedy
Risk
The standard requires child seat lower anchorages in two seating positions for vehicles with three rear seating positions. the standard cab and cargo van vehicles, which only have front seating positions, have an air bag off switch to disable the front passenger air bag and do not have child restraint lower anchorages in the passenger seat. the standard requires passenger seat child seat lower anchorages in vehicles with an air bag off switch. However, the standard does not require vehicles with only front seating positions to have lower anchorage provisions if the vehicle IS not equipped with an air bag off switch.
Remedy
To bring the standard cab and cargo van vehicles into compliance, dealers will inject epoxy into the air bag off switch to prevent air bag activation, relocate the switch behind the instrument panel and then install a cover over the resulting opening. the sun visor label and owner's manual will also be changed. the correction for the extended cab vehicle will consist of changing the front passenger seat to a seat that has child restraint lower anchorages. the recall began on september 9, 2004. owners should contact chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.

Risk and remedy
Risk
The bedliner can become detached from the pickup while it IS motion, possibly endangering following motorists or pedestrians.
Remedy
Durakon will issue a press release in attempt to notify customers that could have purchased the defective bedliner. if you purchased either a durakon allstar of patriot overrail bedliner since august 1, 2003, for 1999 to 2004 chevrolet silverado or GMC sierra trucks, or purchased one of these pickup trucks with either brand bedliner already installed, you should return to an authorized durakon dealer so that the bedliner can be inspected and, if necessary, repaired with a newly designed toggle wing fastening system, or if required, replaced with a new bedliner free of charge. please call the durakon hotline at 1-800-933-4200 to find the nearest authorized durakon dealer.
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.
Risk and remedy
Risk
Anyone sitting or standing on the horizontal surface of the tailgate when both cables fractured could be injured by falling from the tailgate. on vehicles that have had the bumper removed, the tailgate may drop even lower. additionally, if there IS cargo on the tailgate the cargo may fall off if the support cables fracture.
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. owners should contact cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463, or visit www.mygmlink.com, and enter your vehicle identification number.
Certain sport utility vehicles, pickup trucks, and passenger vans fail to comply with the requirements of federal motor vehicle safety standard no. 135, ?passenger car brake systems.? some of these vehicles were produced with an out-of-specification brake hydro-boost housing relief valve bore.
Risk and remedy
Risk
Consequently, the valve o-ring seal may fracture. steering efforts may be slightly increased while braking or parking. under certain driving conditions, a fractured seal may require a slight increase in the applied brake pedal effort to achieve the same vehicle deceleration rate as prior to the seat fracture.
Remedy
Dealers are to replace the hydro-boost relief valve. the recall began on june 18, 2004. owners should contact cadillac at 1-866-982-2339; chevrolet at 1-800-630-2438; GMC at 1-866-996-9463; or hummer at 1-866-486-6376.

Brakes failed suddenly due to severely corroded brake lines. brake pedal was slightly mushy at stop sign coming off of freeway. at the next stop sign (3-WAY intersection on 55-mph county highway) the pedal went right to the floor. fortunately there was nobody in the intersection or a serious accident may have occurred. apparently gm's position IS that brake lines are maintenance item, and this IS normal wear and tear, which IS ridiculous. I've owned older vehicles (including a nearly 50-year old chevrolet truck) in snow country and have never seen brake lines this rusty. I am very fortunate the rupture did not occur in an emergency braking situation.

While exiting of a highway and traveling 25 mph my brakes completely failed. I pushed the pedal to the floor several times but it did not slow the truck. As a result I rear ended a vehicle in front of me. I had now warning or check light for the brakes previous or since. Upon inspection I discovered corroded and leaking brake lines in the middle section of my truck.

I was driving along and had to hit the brakes immediately. I almost hit the car in front of me. I noticed I had to start putting the brakes all the way to the floor in order to stop, especially on an incline. The brake light went on and off a few times so I took it to a shop to have it looked at. They told me that my brake line blew and all the other brake lines are rusted and the truck IS not safe to drive. this truck IS only 11 years old, that IS absolutely unacceptable that all the brake lines are rusted. The truck only has 108K miles. I called a local chevy dealership and they quoted me 3K+ to fix it. It involved at least 20 hours of labor and they needed to lift the frame off to fix. I can not believe their are no recalls from gm or atleast them offering any help to pay for this. The dealer did not offer me any help or remedy to the situation, just wanted me to fork up 3K.

My brother inlaw owns a 2003 GMC sierra and experienced total brake failure due to corroded brake lines in 2009. Upon inspecting my brake lines on my 2004 silverado I observed the the brake lines were corroded and would have to be replaced before they failed as well. My truck was only 5 years old at the time! After much discussion with the dealership where I purchased this vehicle I determined that they would not stand behind their product and had to pay out of pocket for the repairs. I still have the corroded brake lines, receipt and pictures of lines on truck before replacement. Keeping all evidence in case of recall. By the way, my exhaust system looks like brand new. Why didn't they use the same material for the brake lines? I don't expect anything to be done about this until cnn starts running stories about people getting killed by this problem!

Air bag warning light occasionally started coming on. Took truck to several independent svc places. They said do not have computer reader for airbags. light started staying on constantly. Took truck to dealers and they said because of liability, the diagnostics are $900 and could run another $1500 or more to fix problem. And, they wanted to keep truck. Truck IS used daily for short runs and has a bunch of equipment on it that would have to be removed in order to leave it somewhere. Because of the staggering cost, and the inconvenience of having to off load the truck and not have its use and the lack of places to work on it at all, we have left it alone. I have driven vehicles without airbags over 3 continents and through jungles & all types of terrain over the last 40 years with out ever needing airbags. Now takata makes a safety device that can shoot and kill you -- do I need this? if so, who pays the repair bill?

On may 29TH my service air bags light came on. In talking with other chevy silver owners of the same year and around that year it seems this IS common. I paid $521.18 to get these air bag sensors replaced on 17 jun15 at a dealer in harrisburg pa., because I was told without the sensors the air bags would not go off. This IS a safety issue I am being told b y other drivers they are just driving around with the service air bag sensor light on. Thats up to them. also on 21 jan 14 I had to have all the brake lines replaced because they had rusted and would not be safe to drive the truck costing $720.00. I was told it was because of northeastern winters and road salts, which I find to be a unexceptable answer to the problem. on 23 dec 03 I paid $356.96 to replace dash cluster which also IS a safety problem. I these safety problems with the silverados are be ignored. My question IS how many people had be affected or injured by these problems?
