THIS IS A DANGEROUS SITUATION- WHICH LEXUS REFUSES TO ACKNOWLEDGE!! THE THROTTLE SENSOR ON MY CAR HAS FAILED THREE TIMES, EACH ABOUT ONE MONTH APART. WHEN IT FAILS, THE CAR RAPIDLY DECELERATES. THE FIRST TWO TIME, THIS HAPPENED AT LOW SPEEDS. THE THIRD TIME IT HAPPENED AT HIGHWAY SPEEDS, IN TIGHT TRAFFIC, AND I NEARLY CRASHED. AFTER MUCH PUSHING ON MY SIDE, I FINALLY FOUND OUT THAT LEXUS KNEW GREASE FROM THE THROTTLE CABLE CAN MIGRATE DOWN TO THE SENSOR, FOOLING THE COMPUTER INTO DETECTING A FAULT. THEY COMPLETELY REDESIGNED THE 2000 SENSOR BODY TO ELIMINATE THE PROBLEM, AND ONLY ON MY THIRD REPAIR DID THEY REPLACE THE THROTTLE BODY. AS YOU CAN IMAGINE, A THROTTLE SENOR FAILURE WHILE PASSING ON A HILL, OR IN DENSE TRAFFIC,CAN BE FATAL. I ASKED THE REGIONAL REP WHY THEY DID NOT AUTHORIZE A RECALL OF ALL 1999 MODELS, AND HE SAID " IT ONLY HAPPENS ON 10% OF ALL CARS"!!! I HAVE A DETAILED DIARY OF THE ENTIRE INTERACTION. SINCE I NO LONGER TRUST LEXUS WITH MY LIFE, WE NEGOTIATED A BUY OUT
