The new part was immediately ordered from Lexus and is to be installed when it comes in. They said they have replaced many of these as they are a design flaw from Lexus directly. 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. Upon investigating further it was observed that the engine lost that amount of oil in just a few miles. After checking the oil she noticed the vehicle had lost 4 quarts of oil. On Friday Septemmy 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. I have attached the original oil cooler hose picture (that was on the car) to this complaint. So my question here is does the Lexus dealer (on 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. And I guess the owner at the time, never had the original oil cooler hose (part rubber) replaced. Also notice that the owner of the vehicle at the time had until March 2013 to have it done. 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. On J(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). Because warranty service contract is best for people who put a lot of miles on a she drop the warranty service contract in September 2017 about, applied the refund to amount owing on car. They change the oil and oil filter, and mention other things about the car, but nothing about oil cooler hose. She takes it to a Lexus service dealer in washington at 95,377 miles on Jto have the oil and oil filter change (note: oil cooler hose is right by the oil filter). Wife bought car on Augfrom dealer in tacoma, wa (with 90,900 miles on it) with a warranty service contract with it. Please, please, please issue a safety recall for this issue. ![]() Had I been driving on the interstate, which I commonly do, this could have caused an accident, engine failure, and worse, a fire. My concern is, that this is and should be a safety recall, due to the nature of the problem. Since the issue occurred after the expiration date, there was no assistance available. 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. The vehicle was towed directly to the nearest authorized Lexus dealer. ![]() Upon further research, it was found that Lexus had issues with the oil cooler hose used during manufacturing, being rubber and leaking or bursting. As soon as it was in park, oil began gushing out into a puddle under the car. ![]() RX350, Sienna, and Highlander reseals run slightly more due to added AWD fluids, seals, and a small increase in labor.Upon arriving home and parking in my driveway, a trail of oil lined my path. CARspec cleans the entire block’s sealing surface and timing cover of all old FIPG and oil residue, taking special care to reapply extra FIPG where the leak may try to redevelop.ĬARspec offers timing cover resealing at competitive rates, including all new gaskets, FIPG, 1282b, coolant, and post-repair alignment. The rebuild uses three entire tubes of FIPG to reseal everything during reassembly. The procedure to reseal the timing cover is time consuming, requiring the entire drive train be dropped out of the car onto a table, cleared of all auxiliary system, totally torn down, cleaned, reglued and reinstalled back into the vehicle. The original FIPG fails, leaving the owner with a mess on their hands and an oil-covered serpentine belt. ![]() This flexible gasket is similar to the silicone liquid gasket you’d use to seal a bath tub or window but is designed to withstand the heat and vibration of a modern engine. The timing cover is sealed using Toyota’s fix in place gasket, FIPG, and 1282b sealant lining the edge of the cover where it meets the block and cylinder head. While the cause of the leak is up for debate, the source of the leak is always the same: where the timing chain’s cover meets the block meets the cylinder head (as seen above).
