The oil cooler pipe broke on my 2011 lexus rx450h starving the engine of oil as I was driving home from work. The part is currently under warranty enhancement by lexus and is a known problem on my model year of vehicle. The malfunction is particularly insidious as oil only leaks when the engine is running, however with a hybrid when the vehicle stops the engine stops and so does the leak at least until you have reached a high enough speed for the engine to kick back on again. In my situation I received no check engine lights, oil lights or any other indication other then suddenly it felt like my engine was running a little rough. I immediately pulled over (I was just on a city street) and found the back of the vehicle was covered in oil. I had the vehicle towed to the local lexus dealership who identified the issue as the oil cooler pipe and lexus corporate paid for the repair under their warranty enhancement. When I picked the vehicle up from lexus of albuquerque I didn't even make it two miles away from the dealership before I started getting all kinds of lights flashing on my dash and the only power I had to move the vehicle was the electric hybrid drive. The vehicle was towed back to lexus which informed me a few days later that the engine had seized. I opened a new case with lexus corporate concerning the engine issues since my engine failure was a result of the warrantied part failing. Lexus's ultimate answer was sorry, but we are unwilling to help you as well as the answer from the dealership. Im the original owner of the vehicle and it has only ever been serviced at lexus dealerships, and not once did a service advisor/manager inform me that this part was a potential problem. For such an integral part that was poorly manufactured and can cause such expensive and catastrophic damage the oil cooler pipe needs to be recalled.

High pressure engine oil cooler hose ruptured causing an immediate loss of all engine oil and stranding my granddaughter in the outback. The vehicle was being driven on a county highway in the country. The vehicle was in motion when the rupture occurred. It appears that lexus is aware of this problem but did not contact me nor apply the warranty extension for my case. I feel a recall is warranted due to the abrupt failure of the hose, engine damage caused, and the likely hood of being stranded in the middle of nowhere.

Something in the dashboard console by the radio has overheated, melting the AC vent on the front passenger side. Little flecks of plastic started blowing out of the vent, and when I looked inside the vent, I could see where the louvered pieces are melted.

I bought a 2011 lexus rx450h new at the dealership february of 2011. Fast forward to summer of 2014. Driving down I-20 in east texas, middle of nowhere, car suddenly has no power, I barely get it on the shoulder. Message on dash "check hybrid system". Tow truck to dealer. Failed or broken fuel pump. Three year old car with 34,336 miles. Replaced under warranty. Fast forward to spring of 2015. Driving on I-55 north. Car dies while highway driving. 41,452 miles. Out of warranty. But, lexus has 1 year warranty parts and labor on repairs. Lexus says, oh, you had bad gas, don't have to honor repair warranty!! Charge was about $ 1,200. They allowed $ 500 credit. Had to pay $655.89 out of pocket. Talked to kroger fuel, where I had purchased premium fuel. Not one complaint from anyone else about fuel from that station. Second bad fuel pump. Fuel purchased before 1st fuel pump failed was from dallas station, not kroger. Very dangerous situation when car stops on interstate. Floorboarding gas pedal, car going less than 10 MPH and slowing, and then refused to move. Would never buy another lexus. Obviously something seriously wrong with fuel pumps. Also, lexus does not honor 1 year repair warranty. Poor business practice.

I drove to a neighborhood subway for lunch. I was unable to release the seat belt when pushing the seat belt release button. Fortunately, I am rather small and slight in stature, 5'9" and 150 lbs., and was able to loosen the belt and squirm free. Took the car to the dealer and received a loaner car while they fixed the vehicle overnight. Thought I should report this as if there had been a fire or I had driven into a flooded area, I would have been a fatality.

I was pulling into a driveway after I fully stopped my car ( I was waiting for another car to pull out of driveway first). When I braked to stop my car it did not respond initially. I could not stop it fast enough to avoid collision w a parked car in driveway. This was so strange because I was moving my car very slowly. I then put it in reverse to back up a couple feet so I could assess damage to cars. When I did this and pressed the accelerator my car accelerated out of control into street. Once again the braking was insufficient to stop my car as desired. Normally the brakes stop this car on a dime (not really on a dime, but normally the brakes are excellent). The later acceleration was witnessed by the owner of the now rear-ended car in driveway. No damage to my car other than to my license plate. No one was injured. There was damage to the parked car in driveway. The damaged car was an older car, a 1970-something bmw, so it didn't have the cool new bumpers that can absorb a low speed impact. Very scary in spite of the relatively the low speeds and short distance & duration of event, this issue could hurt someone.
