Hummer H3 Questions

Safety hazard if the exhaust manifold is cracked? (1 answer)

Shouldn't this be a recall on GMS part as a safety issue? I have been told that a cracked manifold is a known issue with these 5 cylinder engines. Can it be welded? Would that be as expensive as a new replacement?

I have a loud squeak by my wheels (1 answer)

It squeeks/rattles when I drive,,,sometimes at an idle a little bit...but stops when I brake. It sounds like its coming from the front passenger side of the vehicle. But it seems to be getting louder. Then for stretches going down the road the noise just goes away. Make any sense to anyone?
