I want to buy an extended warranty can i just go to the dealer and buy one for the power- train 2006 H3 I-5 49000 currently no issues except AC wiring.

 

Suggest you check out this GM dealer as you can buy online. Actually, I took there price, dropped it by $100 and asked me dealer if they will match it. They did! If you are still able to, would suggest you buy the GM warranty as so many of these other 3rd party warranty companies close down or simply don't honor the warranty after the fact.
