Have you had your heads replaced? They had to replace heads on the 12 and some 13's. They then extended the warranty to I think 250K miles. Mine were replaced at about 30K.

2012 rubicon dieing

Fuel pump or possible PCM issue is my guess. Random shut off. Does it run rough? How long has it been doing this?

Could just be a sensor too.

Doesn't run rough at all. Something is just telling it to shutdown. Starts right back but wont go into any gear til you've started it 2 or 3 times. Automatic transmission

Took it to a dealer bout a week ago for the recall on the mirrors. They hit it with 2 flashes. One TCM and one PCM

Was it having this issue before taking it to the dealer? If not, take it back and tell them to fix it, on their dime.

Re: 2012 rubicon dieing

if your trans won't engage, you're probably having computer issues. Did the vehicle have an aftermarket tune? Sounds like fuel map/idle is off as well.
