2003 GMC Sierra 2500HD review from North America
"GM power at it's best"
What things have gone wrong with the car?
The only problem that we have had at all is a small piece fell off of the wiper arm (you can't fold them out like the old ones!)
General comments?
This is one heck of a good truck. We got the Duramax diesel and Allison trans. combination. WOW. The transmission in the tow/haul mode is great (unlike what I have heard about Ford's tow/haul mode in their transmissions). The Duramax engine is in my opinion the best diesel engine on the market. It is very quiet, doesn't sound like a school bus! (cough..powerstroke..cough..cummins)
:) At 27K we are getting 18mpg and it has slowly been improving as the mileage goes up.
