We are in the same boat., My husband bought the Extended warranty thru CarMax as well and they don not want to cover. We are in the biggest mess with CarMax we will never do business with them again, they just give us the run around.
They had to send our truck to a local fleet shop to do the work, We went to that shop, Since our claim was denied, CarMax decided not to work on it any more. That it was the fleet shops problem. been with out a Truck for3 weeks.
What do I do now.
Anyone one else going thru this, lets do something about it.
