Ford Auto Start Stop

Something else to break as they get older.

Source on the engine damage? I've done some research on that myself and haven't found anything credible to suggest otherwise. I might be wrong though.

My gosh man... do a google search for AFM lifter problems and you can read all you want to about it.
You can decide for yourself if it is "credible" or not, but I know it is.
I know of 2 people with 2012/2013 Silverados that had major damage at around 145 K

Call Royce Brooks Garage in Abilene-They have seen a few of them already
They don't show any signs of trouble until they go bad.

There are companies that sell rebuild kits for this type of failure/wear problem.
Lifters and cams I think.

I always thought the start stop would cuase more wear & tear on starters, alternators & batteries...glad I got a 14' F150

yes, but think about it.. it makes the vehicle get .00002387713 more miles per gallon!
So over the life of the vehicle it will save 2 gallons of gas!!

Ohhh...hell it's worth it then for 2 more gallons... lol

There's definitely longevity issues with the AFM system, at least the older models. The whole system is worth about 1-2 mpg in steady state light load freeway driving from my personal experience.

If you're mechanically inclined, planning on keeping your AFM-equipped vehicle past 100k, and don't care about the fuel mileage? Doing an AFM delete while picking up a fair bit of power is only cash and a weekend away. These motors are incredibly easy to work on without screwing them up, and there's a lot of AFM-delete kits on the market. The biggest downside is you have to strip the motor down to the shortblock, but that's not as intimidating as it sounds.
