I have 2013 Cmax which I purchased in Feb 13. Looks like the 12v battery(Group 67R orginal) is going bad. Guess the HV pack is the only thing saving me if I drive on regular basis. I keep one of the Lithium jump starters in vehicle just in case. Has anyone tried the 90/T5 battery that Sam's sells to use in their vehicle? Looks like it has the same size but bigger CCA and seems to be cheaper ($105.88 in my area) alternative. Looks like Interstate recommends on their web site. Let me know.
Got our check yesterday. $475, but still when I bought it in Feb 2013 they sure did not discount it much. My bad...I guess. My mileage here in DFW is about 39 but you have to drive fast, or get ran over.
