NHTSA Complaint #10629541 — 2007 LEXUS RX350

I RECEIVED LETTER FROM LEXUS TELLING ME THE ENGINE OIL COOLER PIPE COULD HAVE LEAKAGE, BUT LEXUS WON'T REPLACE IT UNLESS IT'S LEAKING. I SEARCHED THE INTERNET AND THERE ARE MANY OTHER CAR OWNERS HAVE HAD THE LEAK AND WHEN IT DOES, THE ENGINE MIGHT BE GONE BECAUSE OF NO OIL LEFT IN THE RESERVOIR. THIS COULD END UP IN AN ACCIDENT OR FIRE, OR AT LEAST ENGINE BLOWS UP. LEXUS ALSO SAID WHEN THIS HAPPENS, THEY WILL ONLY REPLACE THE DEFECTIVE PIPE, TOYOTA PART NUMBER: 15767-31020 PIPE, OIL COOLER, THUS LEAVING OWNERS TO PAY THOUSANDS FOR A NEW OR REBUILT ENGINE. WHY DON'T THEY JUST REPLACE THE DEFECTIVE RUBBER PIPE WITH THEIR NEW METAL PIPE? I AM SURE THEY ARE AWARE OF THE PROBLEM, IT WILL HAPPEN SOONER OR LATER. PLEASE HELP! *TR
