Manifold/header/muffler/tail Pipe problems of the 2005 Chevrolet Silverado 1500

Exhaust manifold bolts coming off heads are falling off pause an exhaust leak and giving me headaches. From the looks of it has been off for quite some time I'm just now noticing it.

I have a broken exhaust manifold bolt. It is a known problem and is impacting my smog certification and safety.

Like so many others, I started to hear a ticking at startup and sometime an exhaust smell in the cab. I found 2 exhaust manifold bolts broken on each side. It can get bad enough to open a window at times. Dealer said it's a common problem. There should be a recall on a emissions and safety issue. I take very good care of my truck and this should not happen. I see it has been a problem since 1999. What can we do to get reimbursed for the cost of repair? if I have an independent repair would gm ever cover it or does it have to be done by a high cost dealership? they got vw for emissions what about gm?.

I went to start my truck in morning to get to work and this loud ticking noise from under the hood, I shut engine off panicking and opened the hood. Went back and started truck again and looked around, I didn't see anything but heard it. Checked oil since it sounded like the lifters but had plenty of oil. Stopped on way to work and got some slick50 supercharge engine treatment. At breaktime checked oil again and added the slick50, started engine and had lifter noise again but quieted down within 30 secs. At the end of my work day started it up and again lifter noise but quieted down again within 30 sec. Broken exhaust manifold bolts were found.

Truck has an exhaust leak at manifolds. 4 bolts have broken off of the manifold. My mechanic said this is very common with this truck and could cost up to and over $1,000. 00 to fix. Check engine light is on so unless I fix it I can't go to state inspection. Also the brake lines are corroded and also need to be replaced. These are all defects not maintenance issues. .

Exhaust manifold bolts breaking off in to the head this is causing exhaust leaks in the engine compartment, noise, carbon monoxide in the engine and cab areas, added heat in the engine compartment, and will not meet the emission standards of some states. Very expensive to repair and gm is not standing behind this issue in the truck with v-8 engines years 1999-2008. Almost all have this issue. Safety hazard. Please look at this. Also, causing problems with the catalytic converter and O2 sensor. Make them step up to the plate.

Too many trucks this way to be CO-incidental.
