I bought a brand new 2017 Ford Fiesta in October. After needing 3 jump starts, i called Ford but they couldn't take me for a week and, since it's important that i have a running car, i bought a new battery via AAA (cheaper than renting a car for a week).
The NEW battery also drained and i needed a jump start in a few days.
When i finally got the car into the dealer, he said the original battery was bad (not surprised as my 2011 Ford fiesta was also sold to me with a bad battery!).
Then, the mechanic said that when the AAA guy replaced my battery, he didn't program it so that's why the new batter didn't work right. Ford is giving me a replacement battery for free as it's under warranty (but they're not reimbursing me for the new battery i bought).
is it true that batteries need to be programmed now? I've never heard of that and it sounds fishy. And if true, is that why the new battery didn't hold a charge?
