2007 GMC 3500 carbon monoxide in cab.
By daveo08 on

Vehicle

2006 GMC Sierra 3500 SLE2 4dr Extended Cab 4WD LB DRW (6.0L 8cyl 4A)

Review

Having driven this truck only a short distance, 2400 miles, problems are already evident. The worst being a diagnosis, from a blood sample test, of carbon monoxide poisoning due to cab infilteration. This is caused by the missfiring of the injection electronics package and the poor cab fit and finish allowing the engine exhaust to get into the cab unless the recirculate mode is used on the heating system. Recirculate is defeated by the controller which will not allow the recirculate mode to be engaged except on max ac. The engine has very poor throttle response and smokes excessively under heavy acceleration. The engine has a propensity to consume oil.

Favorite Features

I would say the seats are the best feature except that the drivers seat cussion has started to collapse and has come loose from the front retainer.

Suggested Improvements

I would try to purchase a better engine from an outside source. This one is junk!
