2007 Lexus RX350: engine failure

Filed May 15, 2019 · Engine · 122,000 miles · PA

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

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.

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.

I was driving on interstate 95 south when I lost the steering capability in my rx350 lexus vehicle. Vehicle had to be towed for repair. Was told it was my A/C compressor that failed that caused my water pump to blowup which caused the serpentine belt to break= $2,308. Not sure I believe all this. When I relayed all this information to my lexus dealer they had no comment. 6,000 miles later I had another major problem, oil leaking that my lexus dealer said had to do with the engine. Lexus removed and resealed engine front cover assy and replaced gaskets $2665.56 also at this time lexus replaced engine front oil cooler supply hose assy and gaskets at no charge saying it was under warranty.

This complaint is regarding the vvt-I oil hose on a 2007 lexus rx350. Either the current rubber hose or the "improved" rubber hose with lexus' service campaign (9lh) doesn't address the safety concern about this hose. This hose routes a high pressure flow of hot engine oil outside the engine block. Rubber deteriorates over time and miles and can unexpectedly break or rupture causing engine oil to rapidly drain from the engine. Despite denials by toyota/lexus, this is in fact a safety issue because ruptured oil lines can and have cause accidents and fires when seized engines and/or oil soaked tires and/or brake pads cause loss of vehicle control and/or motorists to become stranded (possibly out of cell phone range). I have contacted lexus to put the correct fix of all metal oil line which it began installing in toyota/lexus vehicles manufactured during april 2008 and lexus refused to do so. I strong urge the federal safety agency to initiate an investigation on this issue due to the safety concern.

The engine in my 2007 lexus rx-350 began making a loud noise and eventually stopped. Fortunately, I was able to maintain control and there was no fire, but the result could have been very different had the event happened on the freeway rather than on a surface street since steering and stopping the vehicle was extremely difficult when the engine died. When I stopped, oil was dripping out onto the ground. After taking the vehicle to westside lexus in houston, it was discovered that a rubber hose on the oil pipe sub assembly (part no. Le15707-31030, I believe) had failed, causing the crankcase oil to spray out over the engine and firewall. Thankfully, there was no fire--this time! Failure of the hose and loss of the crankcase oil caused a number of catastrophic failures to occur. First, since the camshaft or some other valve train component was seizing up, the timing chain jumped time from one of the sprockets, causing at least two of the intake valves to be struck by the pistons, this necessitated replacement of over $2750 worth of parts under warranty, including the alternator which was apparently directly hit with a spray of oil. I asked that the engine be replaced, but westside lexus refused, saying there would be no reduction in engine longevity due to loss of the engine oil. There was no oil showing on the dipstick when it was checked after the incident, but the service technician, mr. Tam, reported that there was an estimated 2 quarts remaining in the crankcase when he drained it and that he didn't expect "bottom end" damage to the main bearings, crankshaft, and connecting rods. I don't know whether this is true or not, but I am concerned that something like this could happen with catastrophic results. The service manager, mr. Michael lorch, indicated that lexus had experienced similar problems on other vehicles and that the part has been redesigned, but no formal recall has been undertaken. Why isn't the hose metal braid instead of rubber?
