Update: I picked up my Jeep from the dealership yesterday. I was told by the service manager they didn't find anything physical wrong. All of the codes were communication based, so they disconnected, cleaned up, and reconnected a bunch of wires, fuses, etc. They cleared the codes, took it for a long test drive (50ish miles based on the miles I sent it to them with) and couldn't re-produce the issue. I have another 40-50 miles on it since then and haven't had anything wrong yet. I hope it really was that simple and I don't have this issue again.

Side note: Everything was covered under warranty. The dealership had no issues with the new tires/wheels I put on, and knew that I used J-scan to update wheel size. Never got any hassle at all from them, no complaints at all. Kunes Country Jeep in Elkhorn. They even had a bunch of new Gladiators on the lot if anybody is looking in the southern Wisconsin/northern Illinois area. Make sure to see my old Army Buddy Eddie the sales guy.

It'll be hard not to always be a bit skeptical from here on out, but I'll try and stay optimistic. Thanks for all the replies.

2021 Gladiator Sport S, 3.6 with auto transmission, 9700 miles. No mods other than new tires. Driving along on a cruise with my wife today when all of a sudden the screen starts going crazy! Luckily I was on back roads because I also lost steering control, it was shifting funny or not shifting at all, the wipers were going on their own, everything was nuts. Shut down it down and restarted it a few times, but it was still crazy. I tried manual shifting, still bonkers. All I could do was limp to a place I could safely park, I unhooked the battery and re-hooked it up to see if things would re-set. Unhooking the battery at least got it to drive normal but with a “Service Transmission” warning and check engine light. I'm so upset right now. I'm hoping my dealer can tow it in and find out what’s wrong. ?

Have you reseated any fuses and/or wiggled some wiring harnesses? That should narrow down some potentially easily fixed problems. I'm not sure which fuses are most prone to this issue, but it's pretty common from what I've read here. 9700 miles is a lot for the issue to happen now, but it's worth a look.

I didn't monkey with anything. I figured I didn't want to give any dealership ammunition to deny a warranty after all the horror stories I've read. And now that the check engine light is on it's theirs to solve anyhow.

Had something similar happen to mine, the dealer did a cpu reset and update. Everything has been fine since, almost 10k ago.

Smart move, letting the dealership deal with it. It's their problem anyway, until the warranty expires.

Man that video is NUTS. Glad y’all are safe though. Hopefully everything gets squared away with it soon.

I had the stuck steering a few times then it happened on the freeway with all the lights flashing and telling me to safely pull over. Find out the battery was drained and needed to be charged. And nothing to be angry about things happen. Be angry if it can’t be fixed and it keeps happening.

Strange times. I have been driving and riding all manner of vehicles for 49 years. Every thing from carbs and breaker points to the FI, CPU controlled stuff. Domestic and foreign. Nothing has left me stranded with these types of electrical issues. Broken cables on the bikes and a fuel pump on the MGB-GT were easy fixes. So much for the "New and Improved" designs. Sorry to hear of your troubles.

Could be a bad ground somewhere.

Ha, I think your qualifier says it all. I have been stranded so. many. times. by all kinds of problems that I just recognize it as inevitable at this point. Hoping this forum arms me enough to be able to handle any JT gremlins on the road, which seem to be 95% electrical/computer issues.
