The exhaust blows white smoke out when just turned on and continues when driving and parked. When in motion I feel shaking and nudges in the vehicles motion when going a consistent speed. The engine line flashes and traction control light turns on while in motion when not need to too.

2002 chevy Tahoe with 105, 000 miles. Changed spark plugs and found a severed exhaust manifold bolt on the engine. The bolt is from the driver's side end of manifold. The bolt is worn and rusty on 90% of it and the other 10% is shiny (like a new break). Called dublin, CA chevy and went in after they said they have had many complaints. The offered to fix it for 10% off the $1000 bill. I told them that it was their defect and they should pay. I called gmac and they told me to goto another chevy dealer in san leandro, CA for a diagnosis since the 1st dealership never looked under the hood. That dealer looked at the truck and told me that they would have to remove the manifold and it would cost approximately, $500, but it could run more if there were more bolts that break off during the repair. I have three young children and I have taken immaculate care of this truck. I don't think I should have to pay for a repair when it is obvious by looking at the bolt that the bolt was over torqued when the vehicle was built. After much research, I have found thousands of complaints of this exact problem. They need to recall these vehicles and fix them. If I let this continue without fixing the problem, I will have a huge problem on my hands and it will be a safety issue.
