gonna be an expensive recall (for FCA); PCM replacement is the fix under this...

Also kinda weird that owners won't begin to get notified until 9/28/18...

Vehicles impacted manufactured between Nov. 28, 2017, and May 28, 2018.

A faulty powertrain controller may keep the vehicles from starting, stall immediately after starting, or stall while driving. The defect is more likely to keep a car from starting than it is to lead to a stall, according to FCA.

If the PCM spare parts situation is anything like many other JL spare parts, there are probably only 3 of them in inventory at the moment. That's the likely cause for the delay. No sense sending us to the dealership if the replacement PCM's aren't available.

Will this cause the idle to surge? Mine surges pretty bad with the a/c on it seems to do it the most when it drops below 14.0v it’s enough to make the Jeep rock a little from the torque if you hold the break at a light. I’m not quite in the affected date for this though.

Bought my first JL June 2018. Water poured from under the dash. They finally gave a voucher for another JL. Purchased another JL on January third 2019. Drove it 376 miles started stalling and push button start would not engage. This one has electrical problems and the dealership has had it for over one month and they are still clueless. I didn't spend $46,000 to not have a vehicle. Not to mention I also traded in my beautiful car.
