Only issue I ever had with them came to a warranty. The item I bought, an ABS sensor had a lifetime warranty but when I went to replace it they no longer carried that brand and all the replacements only had a one year. Pretty typical I guess. I only had the car for a little while longer anyway. In the same topic. I have a Sears Diehard that was advertised in 1978 as the last battery you will ever buy. Anybody know where I can get it replaced?
