2001 GMC Yukon XL Denali Reviews
I brought my 2001 Yukon XL Denali new and still drive it today. It has 183K+ and is still in what I would call excellent condition. I'm a mechanic and have done all of my own work after my warranty expired. Although, I've had many parts failures (2 x more than my 97 Chevy C1500 PU which I also still drives), I still would rate this vehicle as "good". The largest part replaced was front differential @ 70k good thing I purchased the extended warranty package. Then there is your normal parts that wear out as well as your service parts (tires, wiper blades, brake pads, rotors and park brake shoes, air & fuel filters, fuel pump, ect.) but I did have problems with water leaking in on passenger floor, an annoying squealing noise and engine serpentine belt wearing faster than normal which took a couple of years of going back and forth to dealer (vehicle under warranty) and they found nothing. So I decided after the warranty ended to T.S. myself and after changing about 3-4 tensioners I decided to buy a high quality tensioner that corrected the belt alinement & wear problem and replacing the A/C belt & tensioner took care of the squealing noise. I just found that the moon roof clogged drains where the culprit that allowed the water drain onto the pass. floor. I would recommend this vehicle.
