I purchased an AC condenser for my car from Rock Auto in May 2009. In less than 24 months, the condenser had corroded out and all of the refrigerant was gone. I called Rock Auto customer service and was told that since the supplier had been "bought out", that the original warranty was no longer valid. How is this my problem? I am out not only $100 for a new condenser, but an additional $150 for a recharge at a shop. After spending a good $1000 or so there in the past couple of years, I am done. I would have been happy with a credit on a new part, but they did not offer anything, zero. They don't stand behind their product.
