Bought my 09 in Sept of 09 with a GM majorgaurd warranty.It was $2400.00 for an additional 4 Years giving me a total of 7 Years. I have also received offers from GM direct om my old now gone H3 about two months ago for an add on once my warranty went on that.
I would contact GM Warranty direct and seee if you can get one on your rig. I understand there is a cut of milage for the waranty and the cost is based on the miles now showing on you odometer.
Also..I had canceled my waranty on my 09 Corvette and got the balance in cash which I applied to the H2. When you cancell your warranty before term with GM they will prorate and refund the diff.
$4000.00 sounds somewaht high to me.
