The answer is yes!!!!
I had a miriad of problems before the factory warranty ran out. So far the extended warranty has covered 2 plugged vent valves and one front stabilizer bushing for about $400. More to come I'm sure.
I bought the Warranties-4-Wheels 10 year, 125K, "0" Ded, for just over $2000 and so far they have been great!
If you tell them Ric Hines or OMAHOG sent you they will give you a $100 discount. Enjoy! See link at:

GMPP may be the best, but they are very expensive and don't cover as long.
