My 2006 Chevy Silverado 1500 extended cab has just over 116000 miles on it and there is a loud knocking coming from the #2 lifter. It only does it when it gets warm or given gas on take off.. it doesn't do it when idling. I know 2 other people that have the same year and model truck with the same issue. I love my truck and I take extremely good care of it but to have it fixed, my mechanic said a new engine is better and cheaper than rebuilding it. Total cost of $6000. And the passenger side door leaks inside the truck when it rains, between the front and rear door. There should be something that Chevrolet can do to fix this problem. I have always loved Chevy, but I'm starting to get very disappointed with them and the quality being made and sold for such high amounts of cash..

My vehicle is burning more oil than normal. I purchased the pickup on Aug 10, 2016 and the day prior the dealership had just done a fresh oil change. I double checked the new oil before driving from the lot and seen the oil was new and fresh. A month and a half later my husband is driving home from cape may New Jersey which is a 6 hour drive and just after filling up his gas tank and driving home...the vehicle starts smoking profusely. He had to add 5 quarts of oil to the vehicle because it looked as though the oil was completely drained from the engine.

Noticed a peculiar exhaust note somewhat like a tick that was reminescent of an exhaust leak. Took vehicle to local muffler exhaust shop and they inform me it is a manifold exhaust leak due to broken bolt(s) on the driver side. Was able to look for myself and I see one bolt head missing in the very back near the firewall.

There has been a long time problem of broken exhaust manifold bolts on 1999 to 2007 Chevy Silverado and GMC Sierra pickups. This problem is on 80 to 90 percent of the trucks with in them years this is millions of vehicles on the road. These vehicles should be recalled by General Motors due to epa laws and emission standards not being able to be passed when these bolts break.
