Engine Oil Leaking Problems of Lexus RX

Tl- the contact owns a 2007 Lexus Rx350. The contact's wife stated that upon accelerating the vehicle after exiting a roundabout, an unknown dust substance began to emit from the exhaust pipe without warning. The contact's wife drove to a gas station and discovered that the oil was empty. The contact then refilled the oil but by the next day, the oil had completely leaked out of the vehicle. Due to the failure, the contact had the vehicle towed to Lexus of maplewood(3000 us-61, maplewood, mn 55109) where they initially discovered metal shavings in the oil line. The oil line was replaced; however, they also discovered that the cam gears in upper engine were defective and needed to be replaced. The manufacturer had been notified of the failure and stated that they would call the contact; the contact had yet to hear from the manufacturer. The vehicle had yet to be repaired. The failure mileage was approximately 83,000. Jo.

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.

I was told by an oil change service that I had an oil leak. I did not drive my vehicle and had to wait over the weekend to get it into a shop. The shop told me that my rubber oil cooler pipe was leaking and it was a bad leak. I cannot drive it. I had it towed to Toyota to look at it since the closets Lexus dealer is 2 hours away. The Toyota dealer informs me that the oil cooler pipe is leaking and needs to be replaced. Through research and a tip from the first auto shop that there is a limited-service campaign for this defective part and Lexus even extended the campaign through December 2021. I am relieved that it will be covered just as it should by Lexus. I get a call from Lexus they are not covering it, because my VIN is not included in the extension of the campaign, even though, my car has the defective part. My car is part of that manufacturing line that had the defective part put in. Please have Lexus expand their vehicles to include all 07-08 Lexus Rx 350's for the limited-service campaign as it is still a problem in those vehicles regardless of the VIN. That is why they gave the extension of the limited-service-campaign because Lexus and Toyota know it is still a problem for Lexus and Toyota owners. If the rubber hose is not replaced it could cause the hose to break and cause engine failure and damage or cause the engine to cease and cause a major accident. This needs to be addressed immediately by Lexus. Thus, I am requesting that Lexus and Toyota need to replace any rubber hoses with the metal ones at no cost to the customer. Thank you.

Rubber oil cooler line developed a leak causing loss of most engine oil within a day. This is a known defect to Lexus who replaces this part with a metal part. However, Lexus has gotten away with a limited time extended warranty when they should be required to recall all vehicles and fix this known defect. To further harm the consumer, their repair book time is five hours when the actual repair time is closer to one hour for one mechanic! my repair costs were close to $1,000!!! Lexus should be required to recall all affected vehicles and fix this part at no cost to the consumer.

Vvt-I rubber oil line ruptured leaking all 6 quarts of oil out of engine, causing catastrophic engine damage while driving in 2008 Lexus Rx350 Toyota should have never put a rubber hose on an oil line with 80psi and they should have issued a recall. The Lexus dealer has never advised me of potential problem. They should have to repair my engine. Furious at Toyota for cutting costs!.

Sever oil leak and engine stop and smoke started coming.

Oil cooler line malfunctioned. Major oil leak, towed vehicle to mechanic. Hopefully no engine damage. This was replaced by Lexus dealer in 09, they used a rubber hose assembly instead of the new metal pipe redesign.

The vvt-I oil line on my Lexus Rx350 burst while driving on a highway. It was a very large leak which covered the ground, engine, and undercarriage. The low engine oil message and engine oil pressure warnings came on when it happened. Complete loss of oil and no visible oil on the dip stick. After looking online and talking with the mechanic this is a known defect with the part though I don't see any recall for it.

Oil leak while driving - engine oil cooling pipe technical service bulletin #l-sb-0154-11 technical service bulletin# zlc technical service bulletin # pol14-02.

My oil line burst on my Lexus Rx 350 SUV and caused severe engine damage as a result. This is a very large leak which covers the ground, engine, and undercarriage. If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate (which it did not, no warning, no illumination of lights) and will result in complete engine failure due to oil starvation. There was no warning lights ahead of time and then all the warning lights went off at the same time when I came out of the store to start the car, and it was towed immediately to a service center and was not driven when the panel lite up (the whole panel illuminated with warnings in every category with no warning to include tire pressure, oil light, engine light, battery light, air bag, srs, master light, brake light, power steering light, electric charging system light). The car has no damage to the undercarriage indicating this could not be the cause. The mechanic reports a defect in the oil line/pump, it cracked and should not have. They are reporting a very large leak that would have occurred thus damaging the entire engine very quickly. With a rupture of this magnitude no oil to the engine, the engine will be irreparably damaged, you cannot just replace . You cannot repair such a massive oil leak without warning because the damage can be done immediately with such a severe loss so suddenly. I never received a recall notice regarding this issue. The only way to fix it is to replace the engine. This is a catastrophe on a car that is in perfect condition, well maintained for all services with only 77,000 miles on it. Vehicle was stationary.

Some how the oil was leaking ,I don t know why?lucky me I was at home doing the yard work when I saw this massive oil leaking on my drive way.

The oil pressure hose busted. I took my car to Lexus and they told me it was a common problem with the car and they have replaced the rubber hose with a metal one. I purchased the metal hose and had it replaced. Oil had already leaked out to the point that cause my engine to lock up.

Oil cooler line leak engine oil empty.

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 transmission on my 1999 Lexus Rx 300 needed to be replaced with only 70,000 miles on the car. I have also had to replace the struts, the radio antenna motor and have a major oil leak repaired.
