Exhaust manifold bolts are broken off on both sides of the 6.0 engine, causing exhaust fumes in the passenger compartment when I driving the vehicle. I have owned this vehicle since new and have never had any engine work done to this vehicle.

Upon starting my truck, the oil pressure gauge immediately goes to 80 with no acceleration. At this point, there is no noise or other lights coming on to warn of other problems. This problem started a few days ago. When truck is in motion the oil pressure gauge continues to stay on 80. I know the 2006 chevy 2500 heavy duty 4x4 have had recalls on different things, but need to see if this is a problem for other chevy trucks as well. I have read several recalls about these trucks and a lot of them we have never been notified to take it to a dealer to be checked. Any help you can give us would be deeply appreciated.
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!
Engine idler pulley seized causing serpentine belt to break which resulted in loss of power steering and loss of power brakes..2 local gm dealer parts department's stated this is common on the duramax diesel engine.
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 line running from the transmission to the radiator is extremely prone to leaking due to a weak/improper crimp in the hose. As time goes on transmission fluid is depleted and could lead to transmission failure. The leak is widespread across most allison transmissions due to a faulty hose crimp and leaks through the crimp in the hose.
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.
I purchased 2006 silverado new and after the 1st year noticed rusting. Just before it came off warranty (2009) the coolant line from the radiator and the brake rotors (front and rear) had rusted through. Have since replaced the rotors again and now my brake line burst open as I was driving home. Entire undercarriage is rusted (frame is peeling up in layers), there is rust coming through the bumpers, on the wheels, in the bed, inside the driver's door - basically everywhere I look (I filed a complaint with chevrolet in 2010 about the excessive rusting and was told, after inspection by local dealer, that there was "no abnormal rusting found"). I baby this truck (it only has 26,000 miles and is not driven on the roads when they are salted) and keep it very clean. I am afraid for my safety as I do not know what is going to fail next. Today I spoke with chevrolet again about the brake lines, again inspected at the local dealer, and was told that it was "normal wear and tear" and caused by environmental conditions. In addition, I was told that the rotors and calipers are rusted through and must be replaced. How is it possible to conclude that the corrosion is due solely to environmental factors and not at all due to material choice and lack of appropriate coating? I am only asking that they cover the replacement of the brake lines and they do not feel obligated to do so. They do not believe it is poor design or subpar materials. (neither of my other two vehicles, 1993 toyota pickup and 2004 volvo, show rusting of the undercarriage to the same degree as the silverado and the brake lines of both other vehicles are completely intact. All three vehicles have been subjected to the same environmental conditions.)
Tl* the contact owns a 2006 chevrolet silverado 2500. The contact stated that while driving various speeds he could hear a ticking sound. The vehicle was taken to the dealer who diagnosed that three of the exhaust manifold bolts were fractured, causing a leak that needed to be replaced . The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 73,000 and current mileage was 77,000.
Bolt head is snapped off on the left exhaust manifold on the rear most bolt. I know of many others who have this same problem and I believe that their should be a recall on the defective bolts used in these vehicles.
