Not that this helps but there have been fire issues with vehicles forever. There were several different recalls on my jeep jk for fire issues, I had at least 2 "fixes" performed on mine there may have been a third I didn't worry about because it actually didn't apply to my build even though they said it did.
I have owned a lot of jeeps and it seems like every model I had went through fire issues. The cherokee did and the grand cherokee did. I think that stuff happens quite often.
Everyone talks about how terrible ford is and how wonderful others are, such as Toyota. My FIL has had more issues with his Toyota Highlander than I can believe. I think it is back at the dealer more often than at his house. It was just at the dealer again last week due to random not starting. He just bought another car, partially, so he has something to drive when the toyota is at the dealer.
Supply issues are definitely causing all sorts of delays and that is hitting everyone it seems.
