Been having battery issues with my 2019 Sahara JL. Late October, it would be totally dead overnite, so I replaced it. Angrily. Then paid $200 for a reprogram at Jeep service The other day my daughter told me while she was at a light, it "glitched out" on her and everything restarted. Seemed fine after that so we didn't get it serviced again. Well, today it was a dead stick again. No lights of any kind. Found with the wipers in the up position despite me not having used them the last time I was in the vehicle. Wouldn't start after a jump from a tow truck, or get into gear, but started doing all types of weird flashy light things and my wipers magically started going back and forth despite me not turning them on. I can't seem to upload video here and the pics don't show the magic happening. But it looked like a job for Ghostbusters. My tow truck driver clutched his chest.
I'll apparently need a tow to the dealership and I'm fresh out of warranty before you ask. (mileage) Don't normally keep my Jeeps this long as I like to switch colors every two years. This is not very reassuring. Was told the service light can mean anything so not to panic about it.
