    i currently have my 2003 gmc sierra 2500 in the repair shop at a local gm dealer. it has been there over a week and they cannot figure out what is wrong with it. The range shift inhibitor light came on the dash board so they replace the transfer case for $2100 and the light is still on and they cannot figure out why. They said the gears were wore out in the 4 wheel drive but i find that hard to believe as it only has 83000 miles and i never used it for heavy duty 4wheel driving just occasional driving on snow roads and driveways nothing major. If you can figure out what is wrong would greatly appreciate any ideas as the dealer cannot seem to figure it out. I would like my truck back without a larger bill already bad enough. thanks for any help

    This truck is starting to nickel and dime me. The block is leaking coolant. The windshield is leaking when it rains (the mats are wet after a rain). Tranny slipping occasionally. Ignition sometimes won't immediately disengage. Trim package is bubbling. This truck heading down the Lemon Path.....

    comfortable and with the 6.0 liter gas V8 an acceptable tow vehicle for my 3 horse trailer. Lots of trouble early on with the steering sector that GM didnt find a solution for until AFTER it was off warranty. Poor gas mileage empty (12 to 12.5) but get about 11 when towing a full trailer. Replaced a radiator at only 70,000 miles and have had trouble with ABS sensors at about 60,000.

    I don't have a Duramax I only have the 6.0 Liter Vortec engine but it pulls just fine. I love this truck to death!!! I just need to find a solution on how to get better fuel economy and how to fix my cruise control that just went out about a week ago.
