“My oil cooler line busted and did not know till I got home thank god the engine did not seize. Come to find out the line is made of rubber and not metal. I understand Lexus is aware but they are not calling for a recall. I th8nk they should pay for work performed”

NHTSA complaint #11415595, filed 2021-05, 115,000 miles

“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.”

“I was driving on 275 highway in tampa, fl, and I got these messages on eco, motor oil and pressure low and check engine the mechanic advised to check with the dealer. Please advice. Thanks”

NHTSA complaint #11351341, filed 2020-08, 15 miles

“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.”

NHTSA complaint #11330770, filed 2020-06, 128,000 miles

“I was slowly entering from i15 to h-78 west. Suddenly car began to rev and accelerate as if I was flooring gas pedal. I jabbed at pedal a couple times and hit brakes...it stopped within a few seconds....not sure if what I did had anything to do with it stopping. My gas pedal is not sticky and smoothly adjusts. My vehicle is in pristine condition and has had all maintenance. I was fortunate I had several car lengths clear. I am 100% certain I did not accidentally slip or push on pedal. While it was accelerating I even lifted foot completely off pedal and it still was going.”
