During a panic stop the brake system light came on and the brakes felt soft but still worked. During the drive the brakes became very weak. When I checked the brake fluid it was empty. I refilled it and started checking for leaks. I found that both the front and rear brake lines we fractured because of the pressure during the panic stop causing the rusted lines to burst. This seems to be a known ( but not reported) problem for this truck in the northern area..

- Fuel system, gasoline
My 1999 GMC sonoma has had a faulty fuel gauge since the vehicle was purchased. It was taken into jim causley's pontiac/gmc in clinton township mi once for warranty repairs but the problem was never fixed. Service rep informed me that it was caused by a bad vehicle ground. Problem still persists to this day. The only way I can avoid running out of gas IS to reset the trip odometer every time I fill-up. *tr

While stepping off of tailgate, both cables snapped and the tailgate fell off of pickup. no broken bones, but bumps and scrapes. cables are sealed, except for the ends, where water must have gotten into them and corroded the cable from the inside. *Tr
- Engine and engine cooling
I have encountered several different chevy/gmc vehicles that are experiencing a lagging start and in some cases no start without a boost. My sonoma has the lag and I have a few friends that have blazers and full size trucks as well. The variation of engine sizes that are affected has me perplexed. I have attempted to run codes with no fault results. This occurs every time I attempt a startup. *Tr

This message was originally sent to my brother advising him of this problem. below IS the explanation. imagine the truck has a couple of tow hooks on the front end like mine did. I would be careful using them to pull the vehicle out of a hole ,using anything other than a chain. Conversely the same would apply if on was using them to pull something.*ak I have been using mine to pull things from time to time but mostly to raise the front of the truck for oil changes etc. today like always, I used my air bumper jack to engage the two hooks and lift the vehicle to work on. Because the air jack IS old and leaks, when you get to the height you want, in a moment or two, the jack will usually settle back down a bit until it engages the safety stop. this usually results in a clunk and some g load to the hooks when it stops. today when it settled onto the stop, both hooks failed at the first attaching bolts! the air jack vaulted into the air and the truck came crashing down to the ground. in another moment, I would have been half under it placing the jack stands! when I think back, there have been times when I changed the oil and did other service work on it with no safety stands, as the air jack has a secure safety latch and the jack pads and the tow hooks have a positive engagement. in looking at the failure, there isn't much meat in the hook assembly where the attachment bolts are threaded into the shank of the hook. The material IS quite hard as there IS no visible deformation in the failure area. I guess in retrospect, the hooks are there for pulling and not lifting but if your truck was down in a ditch you would use these hooks to pull/lift the vehicle out. I wouldn't want to be standing in the way if one of them failed and launched a hook of considerable mass into the air. john

The driver's seat adjust failed. no pressure--could be put on the seat without it moving to the full back position. the dealer initially replaced this in mar 05 after me and dealer speaking with GMC customer satisfaction. GMC reimbursed me for costs. 15 months [!!] later, it failed again. the dealer had only seen this issue twice, both times with my car. GMC initially declined to pay for the repair. then, after discussion with me, they offered to pay for it with me understanding that they had no liability and would not pay for any future repairs or would offer me $500 certificate discount on a new GMC truck. when I mentioned the safety issue potential, they wanted me to understand that if I accepted the money, I would have no standing in future problems of the same nature. I decline. I am concerned about the safety potential of this. they have twice corrected the symptoms. IS there an underlying cause??? Are others having similar issues. I hope you can help to get a handle on this for me and, potentially, for others, too. thank you. *Jb

Not sure if belt broke first or fan blade the blade broke off and flew inside of truck causing damage to parts under the hood it was 1000.00 to fix all the parts broken by this.

- 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.
