GM mad a faulty bolt design and no one is holding them accountable. I have 3 broken manifold bolts and the dealership wants $2100 to repair. There are thousands upon thousands of others just like me who are helpless. Why are you and the epa doing nothing? the vehicle can't pass emissions like this!

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.

Transmission slipping, banging periodically 1,2,3 gear and down shift. Transmission gauge red-lined, now is not properly showing temp. Oil gauge is moving 0 to 80 all the time. Some lights have been going out on panel and steering wheel. Check engine light on and off. Transmission company diagnosed as a possible electrical issue and Chevy states the transmission bang and slip is common and no repairs are needed? help.

The contact owns a 2006 Chevrolet Silverado. The contact stated that while driving at approximately 10 mph, the vehicle stalled without warning. The failure occurred on two occasions. The vehicle was taken to an independent mechanic where the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 90,000.

Vehicle under carriage looks more like a 30 year old vehicle. Brakes lines have failed causing extended stopping distance or swerving off road to avoid collision. Oil cooler lined ruptured and leaked oil on exhaust manifold, a potential fire hazard, especially when all the exhaust manifolds rotted as well so hot exhaust gases are not directed out the exhaust, also a concern for poisoning occupants with toxic exhaust gases. Power steering fittings rotted causing loss of steering. GM is useless, when I contacted them they said it is the environment. I asked them why a Toyota and Acura, both 8 years older showed no such failures or even signs of rust on critical components. GM responded that they couldn't answer that question. Hmmm, I wonder why. In 39 years of driving, it is the most I ever paid for a vehicle, 48,000 dollars, and the manufacturer refuses any assistance. That's the thanks for bailing them out. It has also had wires to blower motor burn, rear brake rotors rotted away at 22,000 miles, ground wires under hood have rotted and fallen of... more potential hazards, A/C compressor seized a came apart. I could go on and on. There needs to be a serious investigation into GM and.the poor quality and lack of concern for the safety of the public. It is by far the worst vehicle I have owned, ever.

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.
