“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. …”
