I purchased a used 2007 lexus rx350 for my 16 year old daughter. It had a little over 100k miles. Everything worked perfectly, no complaints whatsoever. Until, my son borrowed it, and while he was driving it, he said it quit. He lost all power steering, so he pulled over. We called a tow truck to tow it to a mechanic. When the mechanic called me, he said the oil cooling line busted, which made the oil pump empty the engine's oil. He said it would need a whole new engine. He said the car is worth nothing. I...

paid $9k for this car a year ago, and now it is not worth $100. The mechanic said this is a known problem for toyota/lexus, but there was no recall. To me - this is unacceptable. In my opinion, since toyota knew of this problem, but didn't recall it, they either need to cover the cost of a new engine, or buy the car back from me. I am very upset over this.

While driving in my neighborhood, I heard a noise. 1-3 Minutes later, the oil light came on. I went straight to the dealer (a mile away), despite the owner's manual indicating no urgency. They said my oil cooler line blew, leaked out all my oil and destroyed my engine within minutes. I came to find out later that this catastrophic, engine-destroying oil line rupture is a known defect to lexus (like the vvt line) but for some reason was never recalled despite it being just as catastrophic/dangerous. Lexus chose...

to use a cheaper rubber hose instead of a metal pipe when the rubber hose can't take those high temps and will blow. 100% Likelihood this will happen'just a matter of when. I researched it and there are millions of toyota and lexus cars affected by this problem'every single '07-'11 rx 350 plus many toyotas. Lexus was made aware of the defect but chose not to fix it. Except in canada, there was a mandatory recall and this part was replaced. For some highly suspicious reason, this didn't happen here. Why? It's dangerous enough to recall in canada, but not the us? Instead of recalling, us lexus issued an insufficient 36 month warranty to replace it, but only if it blew during this time. If it didn't leak within that time, you're screwed. Lexus messed up its vin tracking system, so people were not made aware of this warranty. For those who were, the issue was downplayed as simply an 'oil seep' instead of an oil line explosion which destroys the engine. Customers were not told at the dealership. We should have been alerted to the defect so we could fix it proactively and spare us the death of a car with only 90k miles. Google this problem to see the thousands of posts/complaints on toyota/lexus websites. There needs to be a mandatory recall and/or reimbursement for those whose engines were destroyed by lexus' known defect. Please take action! Please.

the warranty service contract in september 2017 about, applied the refund to amount owing on car. 4. On june 23, 2018 (at 99850 miles) the (original manufacturer) oil cooler hose leak oil a-lot, in about 1/2 a mile all the oil (6 qtrs +) was out of the engine maybe, she did not notice the leak until 3 + miles of running the car, (no light came on the dash). 5. So read that in march 2010 toyota had their car engines with year 2007 had the dealer replace the oil cool hose (part of the hose was rubber-and was known to leak, the oil cool hose now is all metal) and the car I'm referring here (2007 lexus rx 350) was part of the replacement to. Also notice that the owner of the vehicle at the time had until march 2013 to have it done. And I guess the owner at the time, never had the original oil cooler hose (part rubber) replaced. 6. So my question here is does the lexus dealer (on 7/13/2017 who change the oil) have any obligation to inform her that she has a oil cooler hose that is known to leak (original one on car that was part rubber)?? 7. I have attached the original oil cooler hose picture (that was on the car) to this complaint. Thanks, for your time

The oil cooling line in my well maintained 2007 rx 350 blew apart without warning, causing all oil to be lost from the engine and catastrophic engine damage totaling thousands of dollars were it to be repaired. This is apparently a very common, well known issue in the 2007 era rx 350 due to lexus' choice to use a rubber cooling line. This occurred with no warning whatsoever.

On my drive to work this am my engine started making a loud noise, I lost almost all of my oil in less than a mile. My oil cooler pipe busted. No warning or anything. Left me stranded on the roadside. If I would have drove it any further it would have costed me an engine. The oil light flashed on and off and my car sounded like a tractor. No warning.

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.

that indicated a newer version of the oil cooler hose would need to be installed. Any potential damage to the engine would have to be accessed after the replacement of the hose and clean-up of the under carriage of the vehicle and insulation surrounding the underside of the car was completed. After researching this topic, we are hopeful lexus will share in the expense of this repair since it has been documented that similar failures have occurred.

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.

This month (august 2016) the care began to make a rattle just after starting the engine.

interesting is that my husband owns a 2009 toyota highlander. His vehicle makes the exact same noise upon starting the engine. He too was told that he needed the vvt gear replaced for a cost of $6k which was only the labor portion. After reading complaints with the 2007 lexus rx 350 and knowing that lexus issued a recall on certain 2008 lexus models for this very issue tells me that a new recall should be made before someone is injured or death occurs. Very disappointed in lexus.

pushed the vehicle out of the parking space, there was a huge puddle of oil where the vehicle had been parked. Then she noticed, the entire back, from the top to bottom was covered in oil. That is why the windshield fluid kept smearing . Once at the dealer, the consumer showed them the notification she received regarding the oil leak. However, the dealer stated the problem she experienced was not the problem that was covered. It was a different hose which had developed a hole causing the massive oil leak. The oil cooler pipe was replaced. *Jb
