My ‘18 JL has been relatively issue free. One quirk it has is occasionally I hear a loud pop through the speakers and the entertainment center will shut itself off.....after a couple of seconds I can power it back on. When that happens the clock resets itself to 12:00.....damn weird.
It seems however since I bypassed that stupid “parasite” battery that runs the auto start/stop function (which I also disabled) it seems to do it less frequently.
If you can get rid of that little battery n yours I’d highly recommend it.
Luckily mine is under the primary battery.
I have a chip that disables the stop start, so once that battery is no good i’ll pull it out.
Thanks for the heads up on that quirk.
The Older JL’s we towed all the time for random electrical issues, but we hardly see any towed past 22 unless they’re accidents.
