NHTSA complaint #11197035, filed 2019-04, 123,345 miles“The engine maintenance required light will not reset anymore after an oil change...even after you follow the steps in the users manual. It used to work because I've done it before. Now, no matter what I do, it won't reset.”
NHTSA complaint #10693769, filed 2015-03, 151,000 miles“My car started leaking oil all over my driveway and into the garage, as soon as I realized what happened I drove it to the dealer. Dealer said front oil cooler hoses were leaking and that I was not the first. Dealer asked Lexus to recall and were refused. This defect is all over the internet since the company used rubber hose instead of metal which they used to use and should have continued to use. The part was covered under warranty but my driveway and garage floor are ruined. The company 1-800 number service person was rude. I was never notified this part was a problem. …”
NHTSA complaint #11019220, filed 2017-08, 89,223 miles“Oil hose leak. Oil pipe which connects to the engine. While driving the hose will leak and you will never be advised that the oil is low. A service bulletin went out to replace the plastic hose to metal. When you take the car to the dealership they try to tell you its not a safety issue but an engine not receiving oil and your truck just breaking down is a safety issue.”
NHTSA complaint #11075795, filed 2018-03, 160,000 miles“Oil cooling line blew out! All oil blew out of engine within minutes. I was stopped immediately with engine warning and had to have emergency tow. The redesigned part was ordered from Lexus at a cost plus shipping of $90. The total repair was $170. This is a faulty part with rubber line that has since been redesigned all metal--no rubber. Lexus has acknowledged the design flaw but no recall.”
