Open the full vehicle complaint log (all categories)I SPECIAL ORDERED A 2003 LEXUS IS 300 IN 2002 IN WHICH WAITED 2 MONTHS FOR ITS ARRIVAL. THERE HAS BEEN SEVERAL RECALLS WITH COMPONENTS ON MY CAR BUT LEXUS SELECTED JUST A FEW TO SEND LETTERS TO. INITIALLY, THE DASHBOARD WAS MANUFACTURE WITH DEFECTIVE MATERIAL AND LEXUS CORPORATION REFUSED TO TAKE CARE OF IT. I AM STILL WORKING ON THIS ISSUE THEN THERE IS THE SENSOR2 BANK1 WHICH MY TRAC OFF BLINKING AND CHECK ENGINE LIGHT STAYS ON. THE SCARY THINGS IS WITH THE SENSOR ISSUE THE CAR WILL STOP RUNNING WITHOUT ANY WARNING. DRIVING ON THE HIGHWAY 60 MILES PER HOUR MY MOTOR STOP RUNNING WHICH CAUSED ANOTHER DRIVER TO HAVE AN ACCIDENT. THE DRIVER TRIED TO AVOID HITTING ME AND HE TOTALED HIS CAR. LEXUS SENT OUT LIMITED RECALL LETTERS THEREFORE I DID NOT KNOW ABOUT THE ISSUE AND COULD HAVE COST MY OR THE DRIVER LIFE. NOW LEXUS WILL NOT CORRECT THIS ISSUE EVEN THOUGH I RESEARCHED AND FOUND THE RECALL. I CALLED LEXUS AND WAS TOLD THERE WASN'T A NEED TO SEND ME LETTER BECAUSE MY VIN # WASN'T ON THE LIST. I ASKED HOW COULD SEND THE LETTERS TO A FEW WHEN MOST OF THE IS 300 HAS THE SAME ISSUE. *TR
