Certain cequent 90 degree 7-WAY right angle adaptors sold by distributors in tow packages for aftermarket sales to tow 5TH wheel rv travel trailers. due to incorrect wiring of the harness, the trailer lights may not operate properly.
Risk and remedy
Risk
If the trailer lights are not working properly, a vehicle crash can occur.
Remedy
All of the defective tow packages are still at the distributor level and have not been sold to any consumers.
On certain trucks equipped with an 8.1L V8 (rpo l8-vin g) engine have a condition in which the engine fuel rail pulse damper retainer clip may fracture resulting in inadequate retention of the damper.
Risk and remedy
Risk
If the damper comes loose, a fuel leak may result. fuel leakage, in the presence of an ignition source, could result in a fire.
Remedy
Dealers will replace the engine fuel rail pulse damper retainer clip free of charge. the recall began on august 31, 2006. owners may contact chevrolet at 1-800-630-2438 and GMC trucks at 1-866-996-9463.
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.
Risk and remedy
Risk
If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.
Remedy
Dealers will install a low-force spring clip retainer for vehicles equipped with a pbr parking brake system. on vehicles equipped with the trw parking brake system, dealers will install a redesigned parking brake cable assembly. the recall began on july 29, 2005. owners may contact chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
On certain crew cab pickup trucks and sport utility vehicles, the 2ND row center occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants, especially smaller occupants, seated in this position. appropriate use of a child seat or booster seat, as recommended for small children, does…
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.
Certain trucks, sport utility vehicles, and vans equipped with bosch hydro-boost brake assemblies, the hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.
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.
Aftermarket pickup truck over-the-rail bedliners manufactured for installation on 1999-2004 chevrolet silverado and GMC sierra pickup trucks. the toggle wing assembly used to attach the bedliner to the truck bed IS not engaging fully in the stake pocket of the pickup truck.
Risk and remedy
Risk
The bedliner can become detached from the pickup while it IS motion, possibly endangering following motorists or pedestrians.
Remedy

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.

I have a 2004 GMC sierra and all of a sudden my airbag light and ABS light came on took it in to have it looked and the airbags are not communicating with the sensor and they would have to go more in depth on the ABS but to go more in depth they charge $80.00 an hour just to be able to figure it out. I have seen similar responses on the airbag light for this vehicle please help.

Rusted out/ corroded brake lines burst while stopping for a deer running out on the road. Was warned of this problem upon purchase of the vehicle in 2010 and personally coated all brake lines B4 winter every year...never saw worse lines! I own classic cars that are twice as old with shiney original brake lines. the fuel lines also rotted out spilling fuel over the top of the fuel tank and on the ground while filling up. All fuel lines and fuel pump connections were severely rotted. Worst I have seen. dash consistently changes languages rendering odometer non functional. Speedometer IS inaccurate some times not even working especially on cold days. hmmmm rotted brakes+no speedometer+leaky fuel lines=crash,bang boom!..and I have a car seat in my vehicle! Luckly I perform preventative maintenance and drive safely. Still wonder how these issues got swept under the rug.

GMC replaced all 8 fuel injectors under warranty at 95,000 miles. same problem again at 135,000 and will not cover them. estimated $5,500 to replace by consumer with only a 12 month warranty. creates poor fuel economy, excessive smoke at idle and will not pass smog if not corrected.

I experienced a brake line failure on my 2004 GMC sierra crew cab pickup truck. I was traveling at a slow rate of speed and coming up to a traffic light and the brake pedal pushed all the way to the floor board. the rear emergency brake was used to stop the vehicle. I found the area around the brake module, in the frame area under the driver's area, soaked with brake fluid and corroded brake lines.

On december 28, 2014 I was driving my 2004 GMC pick-up truck and suffered total loss of brakes. This happened as I was approaching an intersection and I narrowly avoided an accident. There was no warning prior to the brake failure - no warning light was on, and no gradual decrease in braking ability. After the failure, I determined that there was a sudden and massive leak of brake fluid from a rusted brake line. Previously, in april of 2014 I had my pick-up truck serviced at an authorized GMC service center. At that time, the service ticket referenced condition of brakes to be in yellow requiring future attention. It was my understanding that the issue at that time was brake rotors would need to be replaced at the next service interval. There was no mention of any potential danger from brake line rusting/failure. Upon researching vehicle issues on the web I have discovered that there seems to be an inordinate number of brake line failures for vehicles of my type. It appears GMC has refused to issue a recall. I had my vehicle towed to the GMC dealer and had them replace rusting brake lines ($801.64). The replacement GMC brake lines installed are of a different (improved) design - they have a painted/protective coating on them, which appears to be an attempt to address past premature brake line failure issues.

I smelled exhaust fumes in the cab of the pickup truck and heard a shrieking sound under the hood. I had to put the window down to relieve my dizziness from the fumes. Upon investigation I found 3 of the 6 bolts broken that fasten the exhaust manifold to the engine. Exhaust fumes are leaking from the burned out gasket. *Tr

Again. My truck had complete brake failure again due to corrosion on the steel lines. This IS an otherwise nice truck with brake lines that look like they've been in the ocean their entire lives. Gm dealer quoted over $1,700 to fix. Gm owned warranty company refuses to cover repair. Gm customer service tells me to pound sand. *tr

Driving on west stone drive kingsport, tn, a vehicle cut me off trying to get thru a traffic light, I locked my brakes down hard as I could, I could feel the ABS system working, I was able to stop about 12 inches from the other vehicle. when I pulled out after the light changed to green, I was traveling down a slight grade, depressing my brake pedal lightly, the pedal went all way to the floor board.. I took the truck to a local shop to have it checked, one of the brake lines behind left front wheel had ruptured. when the mechanic started the repairs, he called said all lines on this truck were extremely rusty, (he asked what I wanted to do) I said fix it right. in making the repairs all lines were replaced.. I have pictures of all lines that can be sent. I also have all of the brake lines that can be looked at and or analyzed. *tr

After having a gm dealer perform oil change, perhaps 1/4 mile down the street from their facility encountered traffic stopped at an intersection in front of me. Applied the brakes to find that they felt mushy, and before completely stopping went to the floor. I used the parking brake to bring the vehicle to a stop without crashing into the cars in front of me. When the light turned green I nursed the vehicle into a parking lot using the parking brake and looked under the hood and could find no issue, the weather was very wet and sloppy, and light snow so I could not see the tell tale fluid leakage from a brake line. Because I had lost all braking I assumed that the master cylinder had failed. I had changed all calipers, rotors and pads several months before, and at 140,000 thought that the master cylinder failing would be unusual, but the only thing that would cause complete failure. After replacing the master I attempted to bleed the system only to find that the problem remained. Now that the under hood area was completely dry it was clear that the failure was rust through at a point the line to the left front wheel was in contact with the frame rail below the master cylinder. The oil change had probably caused movement of the line resulting in the failure. Moving some of the other lines made it apparent that all of the hard lines were shot. The slightest movement caused them to fracture. Worse than that, they were all encased in a "shell" of rust from one end to the other, concealing how fragile and dangerous they really were. Repair estimates were anywhere from $800 (local mechanics) to $3,400 (gm dealer). Lovely. I had a 1994 S10 blazer that I sold a couple of years ago with 290,000 miles on it, original brake lines and all. Changed the lines myself in a weekend for $120.00, the gm parts guy new exactly what I needed and had the "kit" in stock, what a surprise. *tr

Exhaust manifold bolts breaking off causing exhaust leak where manifold bolts onto head. Due to exhaust leak now vehicle IS throwing codes for catalytic threshold low. Which leads to a magnitude of problems to lack of power, poor fuel mileage and not being able to pass emission test in some states. Problem results in upward of thousand dollars in repair for faulty bolts, after researching said problem it IS a common problem with gm V8 of this year older and newer as well. This IS a major defect and flaw in gm's design and needs to be addressed aspa!!! This IS a prob that IS affecting epa laws and needs action taken against gm to fix this problem before it gets worse. Gm needs to be held responsible for their vehicles and poor design and or products that go into them that causes laws or safety to be broken or effected! *js

At the above listed date my vehicle began blowing excessive blue smoke through the exhaust. I discovered at that time there had been a recall on the fuel injectors several years before. I attempted to remedy this with gm at that time and was told I was too late past the date to get service on the recall. I was not notified of a recall and would have taken care of it at that time. It continues to blow excessive smoke but only at idle. I wish to have the problem corrected as it IS hurting the environment. I was given a price at the local dealership to repair this issue. I don't feel I should have to pay to have it corrected as there was a recall on the problem. *tr

The heating and ac controls were replaced 2 times in 2007.and are still not working properly today I was driving home with the ac on because it's 99 degrees in los angeles county and like it has been doing for years it started blowing hot air on its own. I have see other gm vehicles with the same issue. So I believe gm IS responsible for correcting this issue. *tr

I was driving in a 40 mph street when I noticed the traffic signal was about to turn red when I applied the brakes the pedal when down to the floor I lost all brakes I slowed down by down shifting the transmission and applying the emergency brake. When I pulled over there was brake fluid leaking all over under drivers side door. Upon inspection I noticed the brake lines rusted out and lost all fluid. I could have been killed there was no warning. I needed to have my brake lines replaced I believe this IS a start of something bad if gm doesn't act on this problem. *tr

I was taking my 4 yr old to school this morning with his 1 yr old sister when the brakes completely failed. Upon approaching a red stoplight at 30 miles per hour with three cars stopped ahead of me I pressed the brake pedal and it went completely to the floor. I pulled gearshift to the low position and swerved into the vacant left hand turning lane to avoid the cars stopped at the light. Then turned hard right as to not enter the busy intersection in front of me with no avail. Somehow we were not hit by another vehicle. At that time I pulled vehicle over to the shoulder of the road which ended abruptly and turned into a grassy area of a baseball field where the vehicle finally came to a stop.gm states that if there IS a brake line failure the vehicle still has braking ability. I can tell you first hand that IS a totally false statement. My vehicle dash did not display any problem prior to this incident. When vehicle was tow to my home I put key in the ignition to check my mileage and now a brake failure message IS displayed.i am very angry with gm for not notifying me of this problem and never had any idea there was an on going issue until today. Myself and my two children could have been killed today because of this neglect. Please do something to rectify this problem because many more gm vehicle will have this problem and innocent people and their families will be hurt or even die. *tr

Brake pedal had no pressure and went to the floor. Truck wouldn't stop. Later I noticed a brake fluid leak. There was no leak before the incident and brakes worked perfectly earlier in the day. If I hadn't been in a parking lot and out on the road, there would certainly have been an accident. *tr

I had not driven my truck in a few months due to other problems with the ventilation controls. While beginning to prepare the truck to tow a 3500 pound boat I needed to reposition the truck in my driveway. The driveway slopes down to the street. while moving the truck, on my driveway, the brake pedal went completely to the floor. Pumping the brakes was not able to stop the truck that was traveling at idle speed. All braking was gone and the truck rolled down the driveway and into traffic on my street. By turning off the engine and coasting to a stop (in gear) just avoided an accident. after getting the truck back in my driveway I found two distinct puddles of brake fluid under the truck. Inspecting the brake lines showed that there were at least two different failure points in the brake lines. One closer to the master cylinder and another a few feet further back. I believe one failure occurred in the front brake circuit and the other was in the rear brake circuit which led to the *complete* loss of braking. This IS contrary to gm claims that this failure can not lead to total brake loss. I have pictures and video of the failure points that I can forward if needed. *tr
