2005 Cadillac Escalade Engine problems

I purchased my car used from a dealership in 2009 and I now have the following problems with it. A check engine light that will not go out, the error states the fuel cap is not tight and no matter how much I tightened it never goes away. When fueling the car fuel will overflow if not paying attention. Also the the shift lever position is no longer illuminated so I am not sure which position the car is in most of the time I have to listen and gauge it before trying to put it in gear. I never received an communications that the car was under recall but from what I am seeing from the nhtsa website these are the problems that I am now having.

I have two cracked exhaust manifold bolts. I have read that thousands of similar vehicles have this same condition. I have an intermittent check engine light that it won't pass emissions. I am also worried of where it is located, that it may cause a fire. I would think gm should have an obligation to fix this defect due to the epa violation & safety risk that it posses. *Tr

From parked position placed key in ignition and started car. All warning light (traction control, emergency brake, service stability, etc) remained illuminated and did not go off. Attempted to turn off car and ignition was stuck in "on" position. Could not turn car off or remove key from ignition. Vehicle had full power and was able to get home even though warning lights activated. Once home, had to try numerous attempts to get vehicle to turn off. Finally, had to unhook battery, pull fuel pump relay, and...

Two exhaust manifold bolts have sheared off causing an exhaust leak on both sides of the engine where the exhaust manifold meets the engine. This will possibly lead to emissions failure and high repair cost for me the owner. It will also harm the environment by the exhaust exiting prior to going through the catalytic converter or muffler. Internet research shows this is a widespread problem and needs to be addressed. This should be a recall. *Tr

Failure of exhaust manifold bolts, dealer says not covered under extended warranty....This is a dangerous situation, obviously this is a design defect and should be looked into....After researching on the internet this is a big problem that gm is ignoring. *Tr

My service airbag came on out of the blue as I was driving, than earlier this year my airride control went out air compressor and shocks , in feb my rear bolts on the drive shaft were loose leaking fluid , my rear seat belt is malfunctioning for my son 8 years get stuck, my air conditioning is hot on one side and cold on the other cadillac changed out a module three months later.

Exhaust manifold bolts are shearing off the engine causing exhaust odor and fumes. *Tr

I have a 2005 cadillac escalade 6.0L engine, with 88,000 miles on it. I had a ticking sound investigated by a local mechanic and he found 3 exhaust manifold bolts, two on one side and one on the other, had spontaneously broken. He indicated before he lifted the hood that was the problem because "that was a common problem with the 6.0L engine". I checked with cadillac owners group and edmunds car space and readily found several similar complaints with the 6.0L gm engine. This should never happen and could lead...
