I don't know if this will effect your problem but the switch on the left is stuck in the down position. After looking at mine both were stuck in the down position. A little WD40 worked wonders.
I look forward to them. I have several. The people placing them on your vehicle mean no harm. They are only paying tribute to your ride. Hell, I'm 78 and it sure doesn't bother me. Keep em coming.
My 2020 LE Rubicon definitely has an aluminum hood as are all the body panels forward of the bed which is steel except for the tailgate which is aluminum and oh yes, the fuel door is plastic.
I've been running them since early 2020 in gun metal. No problems so far. Since you live in a high salt area I'm not surprised. Down here in God's land called Texas we don't see much salt on the roads at least not in the Dallas area. You better take corrective action soon. Aluminum cancer...
