1 Radiator Hose problem of the 2009 Lexus RX350

Failure Date: 08/27/2017

The oil cooler manifold which has rubber hoses leaked completely out. The new parts have a solid metal hose, not rubber! I believe Lexus obviously knew the rubber hoses were a cheaper method of cooling, though they are "high pressure" and should have been metal at the time of manufacturing the vehicle! I have seen blog after blog of people with the same issue. Oil all over my driveway and again, I believe the motor has been damaged due to driving home (unaware there was an issue) until I saw the oil everywhere underneath and on the side of the motor.

4 Radiator Hose problem of the 2007 Lexus RX350

Failure Date: 06/16/2012

Driving home from work late at night my car started to make sounds it smelled like rubber burning. My display panel showed no trouble lights were on. I knew I had just had the oil changed the oil light was not on. I am a 61 year old woman on a dark back road with no lights or cars around me I was not stopping. After driving 10 miles finally I was a block from home now the oil light comes on. My husband checked the oil and saw that the oil stick was dry. I called where I had my oil changed and explained and they said to have the car towed to them. Once they checked it out he called and said my oil cooler hose blew apart he said they see this alot in 2007 Lexus RX 350 and I should call my dealer. I called the Lexus service dealer the service guy said it was under warranty. I asked if my motor was ruined will Lexus fix it he said yes Toyota would have to eat the cost. I had the car towed to Lexus I got a call from the Lexus service dept he said it was not under warranty. He said I would have to pay almost 600. 00 to have a new hose installed. I went off on him. My car has 75000. 00 miles I have owned cars with 115+ miles and never had a oil hose go bad. The scary thing is there is no warning when this hose blows. The dash board panel lights should indicate there is a problem service is needed something! for the hose to blow apart in just a second like it did the hose has a default. Toyota has known about this problem and refuses to do a recall at this time. We need to have a class action law suit. This is so dangerous why is Toyota not taking care of this problem they wait until deaths occur.
