I know the has been issues with the newer Jeep Grand Cherokee’s with dead batteries. Found this TikTok video on a jeep form about a 150 Amp “inline” fuse that blows. Would have never guessed there was a fuse on the outside of the fuse box and inline with the battery cabling.
Good info to keep in your memory bank.
