(to see the school bus engine sizes…
Risk and remedy
Risk
This condition may cause an inadequate seal at the connection, potentially leading to a fuel leak. In the presence of an ignition source, a fire could occur.
Remedy
Honeywell will notify owners and replace the fuel filters free of charge. the recall began on october 18, 2006. owners may contact fram customer service at 1-800-890-2075 (option 1).
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.
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.

4"Takata recall" the contact owns a 2004 chevy avalanche with a set of capitol precision trac ll tires on it. While pulling off in the vehicle and driving around 35 mph you could feel the back end shaking and wobbling like the lug nuts were loose. The vehicle was pulled off the road to investigate the shaking issue where was found that the tires tread was separating making humps and waves in the tread. This happened on the highway at 92,207 miles on vehicle and 7, 319 miles on 265/70r17 capitol precision trac ll tires. The vehicle was parked for a few days until getting tires to replace the capitol tires but once the vehicle started moving to take it to the shop to replace the tires the front had started to shake just like the back at 92,221 miles on the vehicle but not as much. Walmart changed the tires and the technician reported the tires were really bad with tread separating from the tire and also that this brand tire were recalled. I have taken these tires back to tire pros where it was purchased and now IS awaiting them to send these tires back to the tire company for an investigation of the tire. The recall # IS 14t013-8570 if I'm not mistaken.

My vehicle has a kelsey hayes ABS module that has already failed twice. First at about 75.000 miles and now at 130.000 miles, always while driving. The module was recalled in 2002 and the manufacturer was given a chance to redesign it, but it IS still a bad part. The blogs are full of owners constantly complaining about this. I had to take gm to the mat to replace the first one since the truck was manufactured after the first recall. This time around I didn't have the time or patience to do so an went ahead an replaced it out of my own pocket. Ia m also stuck with this part as it IS not replaceable with any other brand. This IS a dangerous glitch that needs to be addressed before someone gets badly hurt. in addition to this problem, the location of the unit (outside the vehicle and exposed to all sort of inclement environments) IS ridiculous! No clever designer would have chosen this placement.

My son had borrowed the truck and was returning it with his 4 and 5 year old sons in the vehicle. he was in a traffic circle and had to brake to avoid an accident. immediately afterwards the brake failure warning came on and the truck had no brakes. Fortunately he was only going about 25 mph and was able to park it on the shoulder and no one was injured. I was able to get it to a local dealer for repair to the tune of $1,952. they diagnosed the problem as a rusted brake line that ruptured and damaged the left caliper. We got no prior warning of the brake failure. In 2012 I also had a sudden brake failure while leaving a parking garage. There was no prior warning or indication that the brakes were not functioning. Again I took it to a local dealer and was told that there was a leak in the master cylinder and I had to have that replaced. No one mentioned anything at that time about rusting brake lines. Although the truck IS 11 years old it only has 67,871 miles.

The brake line burst as I was shifting into drive could not stop vehicle, shifted it into park and was able to stop before hitting someone. Why are these lines not made of stainless steel? Better yet why IS this agency not doing anything about this? They jump all over a key switch that may cause a problem but do nothing for something as important as be able to safely stop our vehicles.

Catastrophic brake failure when attempting to stop vehicle at 45 miles per hour. brake peddle went to floor almost causing a major crash. GMC dealer stated brake lines totally rusted out and ruptured causing total brake failure. dealer stated brake lines disintegrated in the technicians hands when the tech was removing old lines. I have read similar experiences from other gm owners on the internet. this IS a major safety issue which if it has not thus far will result in injury and or death.

My husband, 3 year old, any myself were driving back from a doctor appointment when we had to make a sudden stop because of a driver 2 cars ahead of us that quickly applied brakes to make a quick right hand turn. the driver in front of us in turn had to apply his breaks on and when my husband applied the brakes on our 2004 chevrolet avalanche there were no brakes!! Our 3 year old was asleep in the backseat!! We hit him of course because we could not stop (going downhill on a busy highway) we ended up having to coast up the hill in the middle of the lane because there was nowhere safe for us to pull off . there were almost several other accidents due to it being a blind spot for drivers coming over the hill both ways and we were stuck there because we had no way to stop ourselves again. so after all that we ended up needing our truck towed and the brake lines are corroded and had busted!! So not only do we have a tow bill now we are responsbile for replacing them! the estimate IS $800!!! Thanks gm! We will be selling this one soon! gm won't do a recall on these after all the complaints and accidents about the brake lines on here? Seriously? we had no clue about any of this until today! the mechanic that IS fixing ours today told us he has 2 more that have the exact same issue and have to be replaced on theirs too! I guess it takes people dying or getting seriously injured before the car manufactures have to take responsibility. and what makes it even worse IS that the whole brake line replacement IS available (for us to purchase) and it's only about $160!! Nice to know the safety of our family, friends, and other motorists aren't worth it to them. just 2 miles earlier we drove though a school zone!!!!! as the kids were leaving for the day! Thank god they lasted that 2 extra miles and no one was seriously injured or killed.

While driving or in park the tachometer sticks as does the speedometer. this has lasted from minutes to days. the vehicle appears to run properly, however, I am very leery of my safety and the safety of my children when they are in control of the vehicle.

I was traveling west on wendover avenue in greensboro, north carolina approximately 8:20 am on thursday october 2, 2014. While traveling a traffic signal was turning red and I began slowing. As I was attempting to slow down the brake pedal continued to travel to the floor and the brake light warning and service brake system light came on. I was quickly closing in on the vehicle in front of me and reduced my speed by standing on the braked and using engine speed shifting from drive to 3RD to 2ND and then to first gear. I was able to stop within a foot of the car in front of me. After this I pulled over to inspect my vehicle. I located a blown brake line that was severely corroded on the drivers side along the frame of the vehicle. Brake fluid was leaking out. In addition, the other brake lines appear to be extremely corroded as well. this IS a major concern considering brakes are such a critical component to safe driving. It appears the brake lines are not made for a suitable quality for such a critical system. The exhaust pipe, which IS under the vehicle as well, IS not corroded and IS made out of suitable quality material. If there are other vehicles out there on the road with similar materials the results may be injurious or deadly. Please help to address and rectify this situation with chevrolet. *tr

I use my avalanche only in the summer to tow a small trailer in my community. I used it in the winters from 2004-2008. I was backing the truck up and applied my brakes and smelled smoke and my brake light went on. I looked under the truck and it was leaking brake fluid. I got down under the truck to get a better look and noticed the brake line was completely rusted through causing all the fluid to leak out. My wife drove the truck to the grocery store that morning and I am so thankful this happened in my driveway because the brakes were fine one minute and it only took a second for the fluid to come out. In seconds I did not have any brakes. this IS the first truck I have owned and I am shocked that something like this could happen. Brake lines should be much stronger than what I have on the truck. This IS not something that you check on a regular basis. I don't use this truck for off road, plowing, driving in the snow. This IS supposed to be a strong vehicle that cost me $44,000 in 2004. I would have been killed if this happened while I was on the road. *tr

- 10112600This Preliminary Information communication provides information to the technician with the axel setup information from American Axle Manufacturing. Technician should be advised that the maximum pinion shim to be used or stacked behind the pinion is 0.050?, and the minimum pinion shim is 0.020? for an 8.6 axle. The range for available pinion depth shims for the 10.5? axle is 0.006? to 0.024?. When setting the backlash it should be set between 0.003? to 0.005? on a new ring and pinion for any American Axle Manufacturing application. The ring and pinion can be reused or adjusted if the mileage is less than 500 miles, if not used for towing. Technician should be advised that a ?roller coaster? or ?hourglass? pattern on the bearings may be normal up to 10,000 miles and possibly longer. With a mis-machined housing you may get a heel pattern on both sides of the gear teeth at build up can generally be corrected with backlash adjustments. When setting up an 8.6? axle with a 5 cut gear set is to use a 0.035? pinion shim and set backlash to 0.004?. When using the newer 2 cut gear set also use a 0.035? pinion shim and still set backlash to 0.004?. To set the gear pattern use backlash to adjust the pattern heel to toe. Use the pinion shim to adjust the height of the pattern. The proper drive pinion bearing pre-load is from 15 - 30 inch pounds with new bearings. The total torque to turn after the differential case is installed should increase 5 - 10 inch pounds at the pinion. A new pinion nut must be used whenever the old one is removed. The axle shaft end play specification is 0.012? per side and the radial specification is 0.002? - 0.003?. Technician should be advised that synthetic lube can be used in all new American Axle Manufacturing axle assemblies. The new pinion seal for the 8.6? axle assembly is a two piece design.
