Upon arriving home and parking in my driveway, a trail of oil lined my path. As soon as it was in park, oil began gushing out into a puddle under the car. Upon further research, it was found that lexus had issues with the oil cooler hose used during manufacturing, being rubber and leaking or bursting. The vehicle was towed directly to the nearest authorized lexus dealer. Upon contacting lexus corporate in regards to the issue, they stated that they had issued and extended warranty for this problem, that expired in december of 2018. Since the issue occurred after the expiration date, there was no assistance available. My concern is, that this is and should be a safety recall, due to the nature of the problem. Had I been driving on the interstate, which I commonly do, this could have caused an accident, engine failure, and worse, a fire. Please, please, please issue a safety recall for this issue. It is absolutely a matter of safety.

I was driving on a country road and noticed A/C was acting odd, then temp gauge went to bottom of dial. I couldn't stop on this road. I was trying to get to granddaughter's house. I stopped at light and couldn't start it. I called aaa and car was transported to lexus dealer who tested car and said engine failed. There were 122000 miles when tested at dealer. The car has been dealer serviced the entire time. It was serviced at 120,000 and all systems ok. I've had an 80 datsun that lasted 250,000 miles. The dealer said that used engine $8500. I expected much better from lexus. Reading some the federal safety agency reports there seem to be a rash of oil lines failing. There was no water hose problem according to dealer checking it

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.

My car never leaked oil, and no sensor lights were on. Regular maintenance was performed on the car. While I was driving on the freeway on cruise control about 70 MPH (2,000 RPM) engine suddenly revved up to 3,000-3,500 RPM. I was able to exit the highway within 0.25 miles, the oil pressure sensor came on at the end of the exit ramp. I drove approximately 100 yards away from the exit ramp to reach a side street and by then the car was barely moving, it was very difficult to turn the steering wheel, and several other sensor lights were also on. I had the car towed to a service garage that told me the oil coolant lines had leaked causing the low pressure condition in the engine. After the technician replaced the oil cooler lines and performed an oil and filter change they found "large quantities of metal shavings in oil filter cartridge indicating internal damage of engine." severe internal engine damage has occurred and engine needs to be replaced. In my experience, it seems that a large quantity of oil was lost very quickly, and if I had not been able to exit the highway within a matter of seconds the car could have seized up and I could have gotten in an accident.

The rubber hose in the oil line to the oil cooler failed, allowing all engine oil to quickly leak out. If this had happened at freeway speeds, the engine would have seized and power steering and power brakes would have been instantly lost... Creating an extremely dangerous situation. Luckily I was driving on surface roads at 25-35 MPH when mine failed lexus knew of this problem and eliminated the rubber hose in its 2011 models but did nothing to warn owners of that vehicle. The federal safety agency was also aware and addressed in the federal safety agency id 10056509 (possibly incorrect id). I'm really pissed that it is going to cost me $500 to fix this lexus defect, but I'm thankful I hadn't driven to my office that day using interstate highways! All lexus vehicles having this defect should be recalled immediately.

On friday september 29 2017 my wife was driving her 2007 rx 350 and she noticed a line of oil leading to her vehicle as it was backed into a parking space. After checking the oil she noticed the vehicle had lost 4 quarts of oil. Upon investigating further it was observed that the engine lost that amount of oil in just a few miles. When we delivered the vehicle to our repair shop on october 4th we were told that it was the rubber oil line that sprung a leak. They said they have replaced many of these as they are a design flaw from lexus directly. The new part was immediately ordered from lexus and is to be installed when it comes in. After all of this I have a question. If this is such a problem part which has been now altered to eliminate the rubber portion on the part, why would I be charged for this part? This has been a known problem for quite some time. As an owner past and present of 9 (nine) toyota/lexus vehicles I'm very concerned about how something like this seems to be accepted by toyota motor corp as apparently no big deal. Had my wife not noticed the leak the engine would've run dry of oil and I'd be looking at a bill for a new engine. Probably $8,000. Does anyone there have an answer other than the quality of parts and engineering at tmc has taken a downward turn. Thank you for listening.

The oil cooler pipe assembly on the engine failed catastrophically causing a sudden lost of a large volume of oil. The failure occurred while driving on a street and was only noticed while parking (a co-worker saw the oil pouring out of the car). The consumer stated he was not made aware of the warranty enhancement program. The consumer requested to be reimbursed for the repairs. Updated 10/10/2017

Lost engine oil driving 20 minutes to work. Lexus dealer advised there is a common problem with the oil cooler line, there is a campaign within 10 years of first use. They won't replace it unless leaking; otherwise you are allowed to drive until the line blows causing catastrophic engine damage. A $60 part ends up being an engine replacement; nevermind the potential danger of an engine freeze at 65 miles an hour.
