We just had our 45k service done and they said my wife's battery CCAs are low, which I believe, but they wanted over $220 to replace the battery! They tried to tell her that not only are their batteries superior, but that the Santa Fe needs a different battery than the normal batteries you get at Sams or Auto Zone. Is there really anything special required for these cars, or am I relegated to paying a premium for a battery that should have lasted longer than 2 years and 3 mos? She has a Santa Fe Ultimate, btw. Thanks in advance.
