I had this happen to my 2011 Lexus 350 RX, with 127,000 miles on it. I was driving on a busy street & it started smoking heavily & someone pulled up beside me & yelled at me to pull over because my car was on fire. I pulled into the nearest parking lot & my dog & I got out, then it immediately caught fire & the engine completely burned up before the Fire Dept got there. After I got home, I noticed most of my oil on the garage floor. Two months earlier, I pulled out of my garage driving from the neighborhood & the oil pressure light came on, so I pulled into a Kwik Kar right by my house. They replaced the oil cooler hose assembly. Seems that the same thing happened again. Needless to say, my car is a total loss.
