I bought my 2002 Yukon XL(1500 2WD) brand new. By 30k miles my transmission went out, Steering wheels went clunk. My computer chip went bad not once but twice leaving the AC and heater running at full blast throughout the day/night until killing the battery. Between 30-45k the transmission had to be completely replaced. The GMC warranty folks just wanted me to agree on a warranty to wash their hands. I asked about all these problems and they were like never heard of anything like this before. After reading some of your viewers posts I see otherwise. I now have 81000 miles on it now and the tranny seal is leaking and the warranty is over. You already know how I feel.
The vehicle is very nice looking. Summit white always clean, 20inch chrome wheels. Gas milelage is OK. I've had it so long that I'm used to it. It's best at a half a tank or better. It does good to excellent when traveling long distance (gas milelage wise)
Sluggish performance when passing. Interior needs an upgrade.
