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.
WHILE DRIVING UNDER 30 MPH. LIGHTS CAME ON FROM THE DASHLIGHTS CAME ON PROMPTING LOW FUEL PRESSURE. SHORTLY AFTER, WEIRD NOISE COMING FROM ENGINE PULLED OVER TO CHECK UNDER THE HOOD. SEEN A LOT OF OIL LOST. HAD THE CAR TOWED TO LEXUS DEALERSHIP AND IDENTIFIED THAT IT WAS HTE ENGINE OIL COOLER PIPE. THIS WAS A KNOWN PROBLEM WITH TOYOTA/LEXUS. WAS TOLD THAT THERE WAS A CAMPAIGN TO ADDRESS THE ISSUE BUT IS EXPIRED BY 10 WEEKS. :(
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.
