@Peja I agree, the dealer is trying to get by with the cheapest method possible. I would think they have an insurance policy for screw ups. If they can get by without making a claim, it might help their rates.
Has anyone else had a dealer install used parts during a warranty claim?
This would not be a warranty claim. Warranty only applies to a factory installed part failing. This is a failure created technician's screw up.
I would have a CarFax run on the car to see if they even reported the CVT being replaced. If it is not reported, that is a huge red flag. At 44,000 miles, you still have factory warranty left on the car. I'm not sure if the CVT's have any sort of serial numbers on them, but if the used one doesn't make it to 60,000 miles or if you paid for an extended warranty, before that, and Subaru checks the numbers, and they don't match up with your car, they may not replace it.
A
remanufactured CVT is $8000.00
I guess an extended, Subaru-backed warranty on the used trans would be a good start.
Like I said above, the most likely source of a used CVT is from a salvaged vehicle. There is no telling what impact it had on any internal parts, depending on why it was a salvage vehicle. The best case would be hail damage. The worst being a hard impact. Unless you have seen the vehicle it came from, it's anyone's guess if it will live a long life or not. Low mileage means zero here.
Now, if it was factory defect, Subaru will only warranty it to the end of the factory warranty. Even if it is a fresh unit. The dealer could use that as an argument, so you might need some legal assistance.
Subaru didn't install a CVT with unknown possibilities of damage created by a possible high speed impact. I would have expected the same from my dealer.
Of course you have to give them credit for even telling you. They could have claimed they put a reman unit in, and unless you had an immediate issue, you would probably have no way of knowing, without having their records between them and Subaru Parts audited.
