1 Manifold/header/muffler/tail Pipe problem

Failure Date: 08/15/2013

The contact owns a 2000 Chevrolet Silverado. The contact stated that while parked, he noticed a loud ticking sound. The contact inspected the vehicle and noticed that the intake manifold bolts were fractured. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 140,000.

2 Manifold/header/muffler/tail Pipe problem

Failure Date: 08/30/2011

Engine exhaust manifold bolt nearest the firewall broken allowing raw untreated engine exhaust to be expelled into atmosphere. Exhaust smell in passenger compartment at slow speeds.

3 Manifold/header/muffler/tail Pipe problem

Failure Date: 07/21/2011

During a utah state safety inspection last year it was found that 3 of the 12 exhaust manifold bolts were broken on my 6. 0l engine. The bolt heads were completely broken off/missing. The broken bolts allow the exhaust manifolds to leak causing problems with emissions. If left undetected this problem can cause the catalytic converter to fail. Just to have the bolts repaired is a very expensive >$500 repair that could have been averted by having these faulty bolts changed out early on. Once the bolts are broken they have to be extracted which is very difficult due to the thermal deformation and corrosion. Two of the bolts were in the rear most holes which have very limited access. I have not received any notices from the manufacturer in regards to this problem. I have owned this truck since it was new. I would like to request a recall from the manufacturer due to the fact that it causes emissions problems and increases pollution. If you consider how many of these trucks, tahoes, and suburbans have been on the road since 1999, the increase in pollution is considerable.

4 Manifold/header/muffler/tail Pipe problem

Failure Date: 09/11/2009

The exhaust manifold bolts are broken off (one on each side at the rear of the motor resulting in an exhaust leak (ticking noise) and also check engine light "on" bad emission codes.

5 Manifold/header/muffler/tail Pipe problem

Failure Date: 02/05/2004

I own a Chevrolet 2500 Silverado truck, four wheel drive with the 6. 0 liter engine. There are three bolts broken off in the intake manifold of the truck due to what I believe was over torquing at the factory.
