2006 GMC Sierra 3500 Extended Cab 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.


Best 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.


Worst Features

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

Review

Bought deisel truck for camper and boat. this truck goes over mountain passes like the load isn't there, 15,000lbs. I bought an aftermarket engine program to increase performance, and with this chip I get 20mpg empty, 15mpg with boat or camper, 13mpg with boat and camper. Programer takes 5 minutes and allows me to program for specific loads or to put it back to stock settings, recommend this. There has not been 1 problem with truck and have already put on 12,000 miles in the first 4 months. Very happy customer.


Best Features

6.0 turbo deisel.10 way adjustable leather seats. Bose sound system. Looks


Worst Features

Have a programable tuning chip from factory. It's very helpful for power when hauling loads and fuel economy when not hauling loads.
