Recently reported ENGINE problems on 2009 Lexus RX 350

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.

Tl* the contact owns a 2009 lexus rx350. while at a fuel station, the contact was alerted by another person that there was oil leaking under the vehicle. the contact had aaa tow the vehicle back home. the vehicle was then towed to lexus of rockville centre (700 sunrise hwy, rockville centre, ny 11570, (516) 665-0166) where it was determined that a hose was leaking oil. the vehicle was not repaired. the manufacturer was made aware of the failure and informed the contact to file a complaint with nhtsa. the failure mileage was 92,000.

The oil cooler manifold which has rubber hoses leaked completely out. the new parts have a solid metal hose, not rubber! i believe lexus obviously knew the rubber hoses were a cheaper method of cooling, though they are "high pressure" and should have been metal at the time of manufacturing the vehicle! i have seen blog after blog of people with the same issue. oil all over my driveway and again, i believe the motor has been damaged due to driving home (unaware there was an issue) until i saw the oil everywhere underneath and on the side of the motor.

Oil coolant manifold. rubber hoses which are high pressure hoses burst. engine issues afterwards due to immediate and extreme oil loss. driving at 55 mph on highway. lexus dealer stated the replacement part is on "national back order, more than 3,000 units". i have had the vehicle fixed as it is a primary vehicle for my family. lexus states they will not reimburse unless it is fixed at a lexus dealer....though they do not have the replacement part! no loaner was offered. cost $321.00 for aftermarket part. there is a service campaign on this issue; sczlc as of 08/01/2014, obviously they are aware of an issue.

Tl* the contact owns a 2008 lexus rx350. while driving 50 mph, the engine stalled without warning. the vehicle was taken to a dealer where it was diagnosed that the oil cooler pipe failed and needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was approximately 70,000. updated 06/01/17*lj the consumer stated the vehicle was not included in the warranty. updated 10/18/2017*js

I saw white smoke in my rear view mirror while driving on a street. no engine lights appeared. i had been driving on the freeway a few minutes earlier. i pulled over and called my lexus dealer, who regularly does my maintenance. i had car towed to dealer, who said it was the vvti oil cooler hose and it would be covered under warranty. next day, dealer tells me they replaced the vvti hose but it was still leaking. it was a different rubber oil hose and would not be covered under warranty. i am not happy. i see that this has been a problem with toyota and lexus so why didn't my dealership replace the vvti hose during a routine oil change and warn me about the rubber hose problem, so i could replace it with a metal one before it leaked. i hope there is no engine damage.

While driving in the very busy freeway, the car suddenly stopped without any prior warning or any signal. upon lexus dealer inspection, the cause was , bolts used to secure the variable valve timing control device can become loose, one of the bolts came out and caused the timing chain to break and it broke the engine head, causing the vehicle to stop while being driven. lexus has not recalled the rx 350 models, however on september 3, 2013 lexus has recalled is 350, is 350c and gs 350 vehicles for the exact same reason. my car has always been serviced at lexus dealer. according to lexus service department, there was no way for me to prevent this or to know. the sudden stop of the vehicle in the freeway as the result of this engine failure could have caused a major accident which was very life threatening. these engines has to be recalled for inspection and repair by lexus. lexus did not accept the fault even though they accepted to pay partial part of the cost of the rebuilding the engine as a courtesy. *tr
