Passlock system engages without cause. When starting my truck, it acts like it will and then shuts down after a second, and then the security light comes on. This IS common with past lock system errors. This happens about 1 out of 4 starts. To get the car started, I have to go through a reset process that takes over 30 min, which causes battery drain. This has left myself and family members stranded in unsafe situations several times. Most recently I was stuck on the side of the highway, after stopping to change a flat at 11PM. After not starting with these same symtoms, while trying to do the 30min. Relearn process, the battery did not have enough to start the truck. So I was then stuck there for 3 more hours waiting on a tow truck for a jump. I was stranded for over 3 1/2 hours. this issue has been happening for the last 2 years, and have spent about 4K dollars to try and fix it.

The frame rail on the left side IS broken in 2 places under the cab area. the frame broke while driving. Now the cab sags 1 in lower where the cab meets the box. body lines no longer match up. there IS no reason a 18 yr old truck with a mint condition body and only driven approx 17500 km per year should break the way it did. This perfectly good step side truck IS now useless and completely unsafe to drive.

Had to have all the brake lines replaced. the lines burst due to them all being rusted out and corroded. I have a 1994 toyota pick up truck with more miles than my 1999 chevy silverado and the brake lines are not rusted or corroded go figure! I was approaching a traffic light and when I applied the brakes, the brake peddle went all the way down to the floor. I pulled over and looked under the truck and saw a puddle of brake fluid on the ground underneath the drivers door and gas tank. I had the vehicle towed to the local chevrolet dealer and all the brake lines were replaced for $1066.33. I was charge for 8 hours of labor. I am pissed off and will never buy another chevrolet vehicle, because of their use of substandard material on the most important part (brakes) of their vehicles and their failing to acknowledge & correct this serious problem with these model year trucks when it was brought to their attention, instead they made bogus excuses as to why these brake lines were failing! I have purchase nine chevrolet vehicles in my life and like I stated earlier I will never buy another chevrolet again and will discourage everyone I know that IS in the market to purchase a vehicle to not buy a chevrolet because, the way chevrolet failed to resolve the brake line problem with these trucks IS unacceptable!

In a letter dated april 20, 2005, gm notified nhtsa that it had decided that defects that relate to motor vehicle safety exist in certain model year (my) 1999-2002 c/k 1500 series (pbr parking brake system) and my 2001-2005 c/k 2500 and 3500 series (trw parking brake system) pickups with manual transmissions.according to gm, some of these vehicles may have conditions that cause the friction linings to wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.gm's action covers an estimated total of 142,585 vehicles.dealers will install a low-force spring clip retainer for vehicles equipped with the pbr parking brake system and install a redesigned parking brake cable assembly on vehicles equipped with the trw parking brake system. A total of 58 non-duplicative complaints were received by odi and gm concerning the approximately 59,000 my 1999-2002 c/k 1500 series pickup trucks with the pbr parking brake system.these included 22 alleged rollaway incidents, resulting in a rate of 38.5 rollaway incidents per 100,000 vehicles.odi IS aware of 24 complaints regarding the my 2001-2005 c/k 2500 and 3500 series manual transmission trucks recalled by gm, including 5 alleging rollaway incidents.though the conditions described in gm's letter are also present in the c/k trucks with automatic transmissions, the rollaway rate in those vehicles was similar to those observed in peer vehicles studied by odi in this investigation.this engineering analysis IS closed. For additional information, see the attached closing report.

Odi opened pe03-057 to assess parking brake ineffectiveness in the subject vehicles.these vehicles are equipped with four wheel disc brakes that incorporate a single-shoe drum-in-hat parking brake independent of the service brakes.complaint and warranty data indicate that the parking brake linings tend to wear out early in the life of the vehicle (at an average of 24 months in service), reducing the parking brake system's torque below that needed to immobilize the vehicle.gm has attributed this accelerated wear to foreign material intrusion and a failure of the brake shoe to properly self-center within its brake drum.effective with the start of my 2003 production, a newer reduced force hold-down clip was introduced to facilitate brake shoe disengagement from the drum surface.this part IS also available at the service level for the my 1999-2002 vehicles.gm has indicated that the paking brake IS intended to operate in conjunction with the transmission to immobilze parked vehicles, and that in many cases, accelerated parking brake lining wear IS caused by rough use, vehicle modifications, and driving with the parking engaged. Odi has upgraded the preliminary evaluation to an engineering analysis to gather further information concerning parking brake usage factors and the circumstances surrounding the seventeen reported vehicle crashes.

- 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.
