OK.....I was trying to determine if GM (Known as Major Guard) was the underwriter.
Regardless, I'm guessing the tire change expense was covered by the regular roadside assistance coverage that comes with the car.
Generally, Autonation sells extended warranties underwritten by Ryan, FYI, and as long as you are still in the 60 day window it should be easy to cancel.
You must call the phone number on the contract and be prepared for a fair amount of pushback......they will try to keep you signed up.
Problem comes in though, as you noted, the contract is rolled into the financing.
So, before cancelling, you must speak with whomever is carrying the loan for guidance.
I suspect, if the amount of refund is paid to you, the lender will recommend passing that amount back to them and then rewrite the loan.
That would be the best case since you are paying interest not only on the car loan, but also on the financed service contract.......so you want to get the loan lowered by that amount.......hurry though. Get your ducks in a row before making the decision.
To any other readers: Never roll a service contract $$$ into a loan if at all avoidable. Service contracts are highly negotiable but if you roll it into the loan the interest you pay negates any discount you received. Always pay for the contract independent of the loan.....
