Unknown what started the issue. While driving it, service electronic control dash light went on. The vehicle started losing power. We were able to get to the highway shoulder. Other dash lights were going on as we were moving over. Immediately after putting it in park and turning the vehicle off, smoke started billowing out from the hood. The vehicle engine was on fire and it was completely destroyed. The only on-going issue we had with it was auto start/stop with both auxiliary and main battery having to be replaced twice over the course of 4 years. There was an active recall for fuel pump component and we were on a waiting list for parts from the dealer since Sept 2023 and we were still waiting.
