There is a known issue in the form of a Warranty Policy Bulletin and I believe a recall in Canada for a faulty engine oil cooler line that was made of rubber and fails under heat (now replaced by metal lines). This happened to my daughter after a hot day and she pulled away from the driveway the next day. Almost all of the oil leaked out and we stopped the car and had it towed to a Lexus dealership. When it was inspected, it was confirmed this was the issue, and there was a noise in the engine. I have a concern that further engine problems may have resulted in a loose bearing needing compete replacement. This has yet to be confirmed, but seems consistent with the many discussion boards that mention this exact issue.

The speakers in my car made a loud noise and I thought someone hit my car. Ever since then it-??ll keep happening and it-??ll startle me when I-??m driving. Sometimes my speakers would have really loud static sound and it-??s impossible to turn it off. It-??s extremely dangerous to be startled like that when I-??m driving.

While driving on a freeway offramp alone about 10 pm Monday August 31 our sunroof suddenly exploded outward. There was a boom in the car, that seemed like a tension release in the front left (driver side) of the vehicle. We did not immediately know what happened but when we stopped at home realized the sunroof had broken outward, glass spilled down into the vehicle when I opened the sunroof cover.

Major oil leaking from a faulty engine oil cooler line while car is moving or turned on. Oil is all over entire undercarriage, back bumper, back windshield & wiper and inside of tires. Garage floor and driveway have oil splattered everywhere. The whole back of car is cover in oil. After researching, I found this is a known issue for Lexus Rx 350/450H models between 2009-2011. No oil or engine warning light came on. Even after the faulty part is repaired, my concern then becomes potential engine failure from lack of oil.

While driving down the highway at 65 mph the sun roof suddenly exploded. There were no other vehicles on the road and no debris. The roof had never been struck and we have never transported anything on the roof. The temperature was 65 degrees and the sun just rising so no significant temperature variations. The road was smooth.

The radio and cd player and sirius radio stations will switch from fm to sirius radio station. Or, the cd player will stop and eject the cd and switch to sirius radio station. Or, the entertainment system will just shut off and you have to try to get it back on by pushing buttons on and off. This happens when in motion driving on a city street or highway. This has been going on for many years and continues.
