I am having the same problem that the person stated about the ABS braking on her 99...even when my truck was still under warrenty the dealer said nothing was wrong and blamed it on the way I drove...like he knows how I drive!!!....I did find that their was recall on othem and the dealer said my truck was not included..in it...well it should have been and should be...doesnt matter the conditions of the road they kick in whenever they feel like it..once it happened and I slid right out into on coming traffic and I was still told nothing was wrong...I think that the dealer never cared....I have 104th on my truck now at 102th I replaced then engine due to 2 broken lifters....I also have a trannie problem while under warrenty and again the dealer refused to admit a problem and I brought it to a aaa cert. Shop and they too also refused that there was a problem...2 1/2 months after the warrenty expired I completly lost my transmission and had my children in the truck when it happened!!!..and again the shops that I went to both still wouldn't acknowledge there was a problem and said I was a problem customer!!! I complained to the warrently place and they too did nothing about.... remind me again why we have warrenties!!! this started in 2002 with these issues and the dealer refused to take back the vehicle!! and now in 2009 I still have issues with the ABS.

The intake manifold cracked on the 1999 Chevy 1500 (Suburban) and let water get into the firing chamber from the cooling system. It happened in 2002 at about 60,000 and again at 2008 at about 110,000... I was told by my mechanic that it was a plastic component that warbles when it heats and cools over time and cracks. It cost over $1000. To replace it each time it cracks. Is there a recall or any way I can get any money from GM for this poorly designed part"?? is there a recall or service bulletin out on the problem????"

Vehicle begins to vibrate on front passenger side at approximately 60 mph for 20-30 seconds then stops. The service engine soon light comes on. Mechanic indicates that the 4th cylinder is skipping. It is my understanding there is no "fix.

Consumer has several problems with vehicle: Front end pulls to the right and left while driving, there are front end alignment problems, it has been aligned, however still pulls to the right and left. Engine is burning antifreeze, when checked shortly after vehicle was serviced the oil was down 2 quarts, vapor recovery tank was empty, antifreeze/water level in antifreeze in radiator was down 1 quart, head gaskets leaking antifreeze into the combustion chamber and burning the antifreeze, check engine light illuminated, coolant level in radiator dropped once the engine was started, there was a minute amount of exhaust gases coming out of the filler neck of the radiator and the water level slowly dropped in the radiator. Vehicle pulls drastically to the left while braking, dealer has replaced brake pads and rear shoes and has refaced rotors and drums, pulling still exists, dealer also replaced the proportioning valve. Transmission makes a ticking noise. A specialist looked at vehicle and observed that when the engine was started, it charges at 15.1 volts direct current which is overhcarging the batter, even after vehicle ran for 15 minutes, the vehicle was still charging at $14.71 volts, the battery has failed 4 times, it has leaked and corroded, check gauges light came on and all gauges went crazy. Vehicle idles high, dealer replaced idler air control valve. Driver side mirror will not turn side to side, dealer replaced faulty mirror switch.
