Our whole fleet and our personal trucks affected by this.
Purchased 1999 Chevrolet Suburban in January 2004. Also purchased warranty, vehicle started to use anitfreeze, returned vehicle to dealership in may 2004 diagnosis intake manifold gasket leaking. Dealership replaced gaskets vehicle started to use antifreeze again. Again we took it back to the dealership November 1, 2004. Service deparment contacted me on November 2, 2004 diagnosis: leaking intake manifold gasket again. We purchased what we thought would be reliable transportation, obviously we were mistaken. If we cannot get to work we cannot make the payents. Im disgusted.
The intake manifold leaked. Consumer was concerned that the engine will be destroyed.
Consumer states intake manifold was leaking. Dealer notified.
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?????.
