Checked oil last week also dealer supposedly changed oil couple days ago yellow triangle light came on it was just bought so unfamiliar with the warning lights tried to look up told me nothing. Today I left a friends house (3miles ) she called and said I left massive oil leak left on her driveway. Sure enough I looked on my driveway and I also had huge oil leak lucky she called me I could have blown the engine or it could have caught fire if I had driven it any farther or she didn't tell me proceeded to look up common Toyota Highlander problems. And there it was saying massive oil leaks from the line exploding also said that the repair Toyota gives to fix the problem has problems too I'm assuming this is what the problem is I'm lucky I was not out on highway having it towed tommorow the picture is at her house she sent after I left. My driveway oil leak is twice that size.
