Have a coworker that “had“ a newer Jeep SUV. I’m thinking Renegade. Anyway, from new, it had all sorts of electrical gremlins. Dealer documented but never isolated it. She was traveling on the interstate after the final “no problem found” visit and suddenly had smoke coming from the dash. By the time she got stopped, flames were coming from the vents. She frantically got her 18 month old granddaughter out with the help of a passerby. She said by the time she got away it had already spread to the front seats. It burned to the ground. The dealer gave her a new “loaner” wrangler while it got sorted. Stellantis contacted her and basically asked if she liked the Wrangler. She settled by keeping the Wrangler minus all payments and other costs with the other one. Ironically at that time, my wife had a 2018 Wrangler that had all kinds of electrical gremlins. Random radio blaring and non responsive, hvac controls going dead, etc. we traded it on the 19 Expy we have now. Fires are definitely scary I’m sure when your driving down the road. Glad in the OP story everyone was ok. New vehicles are rolling computers surrounded by all kinds of crazy flammable parts. most Vehicles have at least some aluminum panels. Magnesium too.
