Ongoing Jeep engine issues post-PCM replacement Sign In

Hi folks,

At my wit's end here with a 2013 Jeep Wrangler.

It recently started bucking on me at high speeds, and if I accelerate when the bucking happens, the engine cuts out and the steering column locks up. It seems to happen if the engine is shifting gears and/or when driving up a grade. After the engine cuts out, it takes 5-10 minutes of rest before the engine is able to turn over again.

The first time it happened I found there were critters building a nest on top of the battery and had it cleared out.

I had the transmission serviced and it's not a transmission issue.

I took it to the dealer for further investigation and was told the PCM was shorting out. Had it replaced and lo and behold, the issue started happening again today after a couple weeks of smooth sailing.

I'm flipping the jeep soon for a new Subaru and I just need to keep the car on the road for another month or so until the new car comes in, and I feel daft paying even more than I have already for these ineffective repairs.

If anyone knows what else this issue could possibly be, I'd appreciate some insight and recommendations.

I'm a first-time poster. Hope this fits here, apologies if it doesn't.

Cheers!

My guess is there is a pin contact problem with one of the plugs, probably at the PCM. That's why it worked for a period of time after they worked in the area.
