Multitask

Without sifting through the thread, if the FFH has a 14 G tank, then why when I'm down to 15 miles to go does it fill only 12 gallons Wouldn't it be closer to 13.5 at the time of 15 miles to go? Unless Ford wants 2 gallons in the tank at all times...

To answer one of the OPs first questions, yes, 3-4 years is normal for the 12v battery to last. some go longer , but not by much. So expaect to replace it about every 3-4 years as normal.

I got the first letter about 6 months ago letting me know that I should get another letter , then got the official one about a month ago. Took it in, they took about 45 minutes with it and it's all done. All they are doing it putting a lubricant on some part of the spring.

I'm not sure what brand my tires are, but I know they are not the 'hybrid' tires, they are standard tires, and I like them for my '13 hybrid My mileage did not change, but I do notice that because they are harder than a hybrid tire, they ride that way too... harder... The good trade off is that they corner much better and handle in the rain better.

Mine is the 13 and just yesterday it's blowing only warm/hot air. COuld this FCIM update help with that? and if so, how much is it if it's out of any warranty?
