I replaced my WSS last Sept. because of a brake and ABS light staying on problem. Well it came back. I went to see a DC dealer and when I talked to the parts manager to buy another, I told him that I thought it would last a little longer than that. He asked me if i still had the recipt, which I do, and told me that over the counter parts are warrantied for 12 months. Said to bring in the part, reciept, VIN and mileage and he would replace it. I didn't know they had that policy. I'll see him on Tuesday.
