Something had broken causing oil draining out of the car while driving on the highway. The car lost power and I pulled over immediately and shut off the engine. I opened the hood and saw nothing wrong, however when I checked the oil, there was no oil. I then proceeded to look under the car and there was oil all over the under carriage. I then did a walk around and found oil all over the back side. Me and my family were stranded while we waited for a tow truck. We had the tow truck take the RX350 to the local Lexus (Kuni in Denver) dealership where this car has been serviced all its life. When I received the initial call from the service department, He had said he is 99% sure this is the oil cooler pipe. He then said this is a known defect in the design of this part. When I googled "RX350 oil cooler pipe" numerous complaints came back. The initial design is rubber and now they installed one that is metal. This could have been fatal if we had traffic near us. Also this could have major damage to the engine. This should have been recalled however Lexus decided not to and just call it a warranty notice. Even with all the information out there about this highly defective part, the dealership would not cover the cost and told us to directly deal with Lexus. If anyone is reading this, and you have not change out this part, I would get this done! It is not an if this will happen, it is when it will happen. The design of this pipe is elementary and will fail. I thought Lexus being a luxury manufacturer would take more care with their customers! But as you can see, they are not.
