Has anyone else ever heard of or dealt with their Jeep losing power while driving and it acts like it cuts out or falls on it's face due to a battery issue.... That is what the dealership is saying that is the problem... They have replaced the battery about three different times now and it doesn't do it for a while but then it does the exact same thing a while later.... Need to figure out this annoying issue.... I can't seem to believe that it is the battery causing this kind of issues, maybe I am wrong though.....

Sounds like a bad ground issue to me, but that's just my knee-jerk answer to most power cuts. I have a hard time believing battery because it SHOULD be self-sustaining enough to run without it once started up (for typical road useage at least).

Sounds like a bad ground or an alternator issue.

How long does the drop in power last? My 2012 had a momentary hiccup that happened several times per month. Replacing the crank position sensor fixed it.

While I don't have my doctorate in batteries, I'm having a hard time believing it is a battery issue. Especially after multiple battery changes. Even if the battery was low on power the alternator would(should) make up the difference. As previously posted it sounds more like a wiring issue.

Did you check to see if there is an error code?
