The computer in the h2 hummer malfunction. Wipers will not turn off. 4 Wheel drive will not engage. Engine light comes on. Everything the computer controls is failing.

Check engine light keeps coming on and light blinks than stays on until I take it in for service. The shop can't figure out why it is doing this had it shop about 7-8 times for service. Also code states can cause a possible fire

Vehicle has 133,000 miles. It has now experienced an exhaust manifold gasket leak due to broken bolts. This is causing noise from the engine area, and is unsafe due to the leak of hot gases being released from the engine at the points of failure (broken bolts). This may be an epa concern as well, and could also lead to failure of catalytic converter. Repair estimate is $1,300. An online search yields hundreds of other results with same failure and complaint on all gm v8 engines for years 1999-2007. This affects the 4.8L, 5.3L, and 6.0L models. This is a design failure and the affected vehicles with these engines should be recalled.

My vehicle's warranty which I purchased separately had just expired but I still went back to dealer as the noise I had reported to them under warranty was now more apparent. Turns out it was due to broken off exhaust header bolts.Now I am out of warranty, dealership will not fix. I have 1 broken on drivers side and 3 on passenger side. Now my check engine light is on showing an oxygen sensor failure or catalytic converter. After researching the internet this problem is affecting thousands of people. Something needs to be addressed !! *Tr
