My 2007 Kluger just went at 135000 kms. It dumped all the oil in about 10kms and coated the bottom of the car, wheel arches and even a mist up the back.
Lucky I found this thread and called up Toyota. They say they will only replace under warranty if it is leaking.
Anyway they sent a tow truck to pick it up, replaced the hose, oil cooler and gave it a basic clean underneath all for no charge.
Just imagine how many cars they could have proactively changed the hose on for what the delayed fix cost them for this one car.
