The catalytic converters leak causing reduced power and exhaust fumes to enter cab. Especially when stopped this can cause nausea and dizziness.
While traveling with the vehicle cruise control set at 45mph the vehicle dropped from 6 cylinders to 4 cylinders. When the vehicle was in 4 cylinder mode and it had to accelerate the entire passenger compartment started to violently vibrate (sorry but that¿s the best description I can give) almost lost control of the vehicle. This is a reoccurring problem Chevrolet so far has changed the tires, realigned the catalytic converter, replaced the exhaust clamps, attempted to replace the entire exhaust system. None of these have yet to resolve the problem. This occurs at all speeds with or without cruise control engaged.
