Used Cars: Used car broke down, motor vehicle commission, car lot

Question
I bough a used ford explorer on May the 2009 and this past weekend the car was making a noise and to the point we were stranded on the side of the road because the car left rear tire locked and we had to get towed home, now we called the used place we bought the car which had certified used vehicle on it and the carfax showed no problems, they have a message on their phone they sell the most reliable working used vehicles and stand by them, but now they are stating in 2 weeks we are the ones at fault and want us to repair a left rear axle, i do not believe this should be paid by us yes we bought the car as is but they sold a car which would not and probably did not pass those tests from the certified used vehicle, shouldn't they pay for the repairs because of this?

Answer
Lorraine,
Well if they stand by their vehicles, they should at least participate in the repair.  What I mean by that is that they should at least get the repair done, at their place, or some place they use, to make sure the repair gets done as cheap as it can, and done right.  Because if you take it somewhere on your own, they are probably going to take you to the cleaners.  Now legally, they dont have to do anything, but with it only being 2 weeks, I would sure like to think they would.  I dont know what state you are in, but here in Oklahoma when a dealer does not satisfy a customer, the customer can call in to the Used Parts and Motor Vehicle Commission, which is basically the "Car Lot Police".  Maybe your state has something comparable, and if so, just advise the dealer that you are going to give them an opportunity to assist in the repair, or you will report them to the higher authorities.
It would be nice if they took care of the whole repair, but if they would just assist in the repair, and split it with you, that would probably be realistically fair.
