Issue started when I noticed the vehicle was burning oil, hence why I had to keep refilling the oil levels often. This is an issue many other RAV4 owners have reported. However, the problem was made worse when my mother used my vehicle to pick up some family from the nearest airport. On her way home, my engine blew a hole through itself, causing an engine fire. If it wasn't for the swift thinking of my stepfather, she, him, and my brothers could've been seriously injured or killed. I firmly believe this has to do with the reason why the engine was burning oil.
