Engine would no longer crank, and car had to be towed to nearest Lexus Certified Repair Facility. Technician scanned the system and found four Codes: P0335, P1603, P1604, P1605. After bore-scoping front three cylinders, technician tried to turn motor by hand and was unable to. The motor turned in reverse, but not forward. Technician removed oil pan to find pieces of valve spring broken and pieces of the piston rings and piston fragments from one of the rear three cylinders.

It has the same engine failure problem as the recall for 2022 and 2023 vehicles. The engine just stalls when it wants with no check engine light or error codes. Then restarts just fine when put in park. Lexus repair could not even find a issue. Have documents to prove it.
First, We are a victim of fraud and scam and are distressed since day one and loss of thousands of dollars. After searching and reviews, we bought a 2015 Lexus RX350 for family use from a seller who had owned this vehicle for over five years but the seller never disclosed and represented in the sale of this vehicle that It was rebuilt and had engine front cover timing gasket leak! They said it was clean title and didn’t have any issues. Plus the blind spot sensors had issues. The same day these problems were recovered after we bought it and from the same first day we tried to return the vehicle and used all other option legally from day one till now to resolve it with the seller, but they didn’t want to resolve neither return it or fix the problems with vehicle but they kept denying. Vehicle been sitting in parking lot since the first day of bought and never able to register and it’s been over 8 months. Also found out, these year models like mine 2015 RX350 timing cover leak were common problem back then. I’m desperately asking to issue a fix remedy by Lexus or Toyota therefore, please help with this.. thanks in advance!
Safety concern: Engine timing cover oil leak. blind spot warning malfunction.

PAST TWO YEARS...MY CAR HAVE TOO MANY TIME PROBLEM ABOUT ENGINE....AFTER FEULING GAS ENGINE SHUTOFF WHILE CAR RUNNING...OR ENGINE SHUTDOWN WHEN WATTING TRAFFIC LIGHTS...
THE PUSH-BUTTON (KEYLESS ENTRY) IGNITION DID NOT KILL THE MOTOR. MY CAR ENGINE RAN FROM APPROXIMATELY 6 P.M. IN AN ENCLOSED GARAGE DIRECTLY BELOW MY BEDROOM. AT 4:30 A.M. I WAS AWAKENED BY MY CARBON MONOXIDE DETECTOR. THE ENTIRE HOUSE WAS FILLED WITH TOXIC FUMES. FIRST RESPONDERS TO MY 911 CALL SAID THE DETECTOR DEFINITELY SAVED MY LIFE. I WAS A LITTLE DIZZY AND HAD A HEADACHE BUT WAS OK AFTER AWHILE. IT TOOK NEARLY 3 HOURS FOR THE FIRST RESPONDERS' CO2 MONITOR TO SHOW SAFE AIR THROUGHOUT MY HOUSE. I HAVE SINCE LEARNED THAT MANY PEOPLE HAVE DIED OR SUFFERED BRAIN DAMAGE UNDER THE SAME CIRCUMSTANCES, AND DOZENS OF PEOPLE HAVE TOLD ME THAT THEY EXPERIENCED SIMILAR FAILURES TO SHUT DOWN THE ENGINE. FORTUNATELY, THEIR CARS WERE NOT IN GARAGES WHEN IT HAPPENED TO THEM.
