Someone help me out on this..I have a 2012 wrangler unlimited. It has 71k on it and just put a 3.5suspension lift with 33's bf good ko's on it bumper and winch. Ran fine but after a few weeks noticed it bucking at 40mph went to dealership they said its because of tires being bigger so they reflashed it. Week later traveling on highway jeep shut off no codes on dash or lights radio was still on and lights. Had brakes n steering..after 10min it started and had no problems until a month later same thing and again ten min starts up..guy at local garage came up with something ..etc rpm performance 1 and code p061c internal. Anyone have this happen to their's? And is this still under warranty for power train? Dealership telling me with no codes on dash they can't help me unless it does it again when its there..I personally don't want to pay $$$$$ for them to say Idk..

Are you still on the original battery? The stock batteries suck and weird things happen when they die. More weird than any other vehicle I've ever owned. My dash instrument cluster went crazy when mine was dying.

Yep original battery

First vote is for a loose ground on the battery. Second is for a bad battery.

Will that pop internal code for powertrain though? We did self diagnosis test with key and that code popped up even though there are no dash symbols lighting up..

yeah i agree.. check the battery.. weird things happen when the battery is going bad. or ground might be loose.

I'm willing to bet it's a bad or out of adjustment crankshaft position sensor.

Google is your friend, BTW.

What was the fix? Same issue here and banging head against wall.

Agree with crankshaft position sensor. Replaced mine, no problems with stalling.
