NHTSA Complaint #10637389 — 2003 TOYOTA RAV4

THIS IS A GENERAL CONCERN QUESTION RE THE ETHICS OF THE TOYOTA CORPORATION. I HAVE HAD CONTINUOUS TROUBLE WITH ENGINE LIGHTS COMING ON WITH THE RESULT BEING O2 SENSOR PROBLEMS. THIS CONTINUED TO HAPPEN WITH APPROXIMATELY 8 CHANGES (I HAVE THE MAJORITY OF THE RECORDS. IN 2010, I RECEIVED NOTICE OF PROBLEMS WITH "HARSH SHIFTING". I CALLED TOYOTA TO INQUIRE ABOUT THIS, AND I WAS ASSURED I WAS NOT HAVING A PROBLEM OR I "WOULD KNOW IT". AT THIS SAME TIME, I WAS HAVING YET ANOTHER ENGINE LIGHT PROBLEM WITH O2 SENSOR CODES AND BROUGHT MY CAR IN.. THE O2 SENSOR REPLACEMENTS WENT ON CONTINUOUSLY FOR QUITE SOME TIME WITHOUT ANY EXPLANATION OF THE CAUSE...EVEN TO THE POINT THAT THEY WERE SENDING THE SENSOR IN TO THE "MAIN OFFICE". UNFORTUNATELY, LAST WEEK MY CAR TOTALLY FAILED, AND THEY ARE NOW TELLING ME IT IS FAILURE OF THE ECM AND/OR THE TRANSMISSION AS WELL! I RECENTLY REVIEWED COMPLAINTS ABOUT THE ECM AND THAT TOYOTA ACTUALLY EXTENDED THE WARRANTY BECAUSE OF THE NUMEROUS COMPLAINTS. IT WAS THEN I LEARNED THAT THE O2 SENSORS HAVE A DEFINITE IMPACT ON THE ECM, ETC. AT NO TIME WHATSOEVER DID THEY EVER CHECK THIS OR INFORM ME. THAT THESE MAY BE RELATED,SO I AM WONDERING IF THEY "PUT OFF" CHECKING THIS POSSIBILITY UNTIL MY CAR PASSED THE 10YR/150,000 MILE EXTENSION OF THE WARRANTY ON THIS COMPONENT SO THAT I WOULD THEN NOT BE ELIGIBLE??? *TR
