2003 GMC Sierra Z71 ext. SLE from North America - Comments

I bought a used 2003 GMC Sierra 4X4 Ext cab with approx 50,000 km - have about 90,000 km now - I had the rear brake pads changed shortly after I bought it, changed the right front wheel bearing and now it sounds noisy again (possibly the left one). I wonder if it's a common problem with them. On the highway, about 70 mph, or higher, there is quite a bit of noise - possibly from the windshield. Comments?

There is not one problem with the 2003 GMC Sierra that I have. All the comfort and the power that any one could want. American made and the money stays right here in the USA, just like it has been for years.

I own a 2003 GMC Sierra also. It has 154,000 miles on it. YES, that's what I said. 154!

The only problem I've had is the compass in the mirror.

I off road this truck regularly. Tow jet skis and always have it loaded for work.

Regular maintenance and knowing how to take care of your vehicle helps.

I love this truck and will never sell it. Will always buy American.

THANK GOD FOR GMC!!

Well...I just bought a 2003 Sierra with 60,000 miles. From what I read here it should provide me with years of good service. I have had both good and bad cars, but will still only buy North American made cars only.

The front differential leaking is a common issue, that is caused from over filling the differential. So when you get it, read your manual and check all the fluids in your truck.

I have a 2003 GMC Sierra with 135,000k miles and haven't had the first problem with it. It had 40,000 when I bought it. Before that I owned a 2001 Silverado Z71 that I bought with 23,000k miles... it had 189,000k when I retired it, and it still ran like a new one, not to mention it had only been in a shop ONCE to fix the parking brake.
