Oil poured out under vehicle under right side passenger side from oil cooler line overnight in my garage. Lexus stated that I was lucky that this did not occur while driving as oil would have blown completely out due to the pressurized line and damaged the engine. There was no warning lights on. I backed the car out of the garage leaving a stream of oil and discovered the problem. I had the vehicle towed to the dealership as I never saw anything like this. According to Lexus service representative this is a known defect and has been upgraded by Lexus to a solid metal line at failure only but only for a specific amount of time. (Evidently the vehicle was manufactured with a part metal and part rubber coolant line that split on the rubber portion of the line.) Seems to me that this should have been a recall to prevent major damage to the vehicle and during driving hazard to consumer as the vehicle would stopped completely as oil would be blown out completely. My cost was estimated and paid for at $695. I think this should have been a recall.

Oil cooler line ruptured while driving. Lexus issued an extended warranty to 12/31/2016 on the Oil Cooler Line. Lexus sent an advisory letter to owners of record several months prior to our purchase. Our dealer: Rohrich Lexus, did not inform us of the problem when purchased 09/2014. Nor did they address the problem when they serviced the vehicle in 08/16, an oil change. Now we have $500 plus in repair costs for the Oil Cooler Line replacement which could have been avoided if Rohrich Service Department had advised us of the Extended Warranty that covered our vehicle. THE OIL COOLER LINE WAS RUBBER AND THE FIX WAS A METAL LINE.

I have never had any issues with the oil and this car has had all of its oil changes on time and regular. Last evening I was driving home and the low oil pressure light came on. Within moments I started hearing a knocking Noise. I parked the car cause I was at home at that time and I checked the next morning and there is no oil in the car now. There's oil all underneath the undercarriage. I looked online and found a story of another guy this happened to and it ended up being an oil cooler pipe. I guess these are rubber and there's a recall warranty notice on these. My car has not been driven since I parked it. Please advise. Car is included in this warranty recall.

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.

My 2011 Lexus Rx 350 has a front timing cover leak. To fix the front timing cover leak, the dealership has an estimated price of $4,000. In order to replace a gasket on the timing cover, many accessories and parts needs to be removed. I think it is a safety issue if the engine is losing oil and it stops running. I also believe that it is a poor engineering design, or a manufacturer error. In order to replace a simple gasket, it requires monumental effort and expense. There are many other gaskets in the car engine that are easily accessible and lasts much longer.

Our 2011 Lexus Rx 350 oil cooler line failed causing engine damage. A family member was driving and the loss of motor oil could have locked the engine and caused an accident. Lexus is willing to pay for the part, but not repair the damage caused by the failed oil cooler line.

My 2011 Lexus RX350 has rubber oil cooler hose and Lexus usa will not replace the pressurized rubber hose despite known incidents of catastrophic failure of the part. On some RX350 models, Lexus has an extended warranty and replacement in case the part is leaking oil, but I was told by Lexus that my particular VIN is not eligible for the extended warranty. But even if I had the warranty, Lexus will not preemptively replace the part, despite 1) safety concern of failure on highway at high speeds and fire hazard risk, 2) potential catastrophic engine failure as the line would rupture and all oil would be lost within seconds and engine would seize and 3) potential environmental damage of loss 6.4 quarts of oil over roadways. Please consider advising Lexus to do a safety recall on all rubber oil cooler hose parts. Thank you.

Parked in driveway in back of house, beside deck after short trip to store. Smelled a melting smell outside. Maybe five minutes later the smell started coming inside the house. We looked outside and saw smoke and thought the house was on fire. We went outside and there was smoke and flames coming from under the hood. Sprayed car with fire extinguisher, which did nothing, then used water hose to spray front of car to keep from the house catching on fire. Car was making popping noises, large amounts of smoke and strong smell. All neighbors came over it was strong. Fire department spent over an hour putting out fire and used their whole tank of water. Front end melted, tires popped, dashboard and windshield destroyed. Cause is unknown
