NHTSA Complaint #10215934 — 2004 TOYOTA PRIUS

THE MULTI-FUNCTION DISPLAY (MFD) FAILED. (CROSS REFERENCE NHSTA COMPLAINT #10173892). THIS IS A KNOWN DESIGN DEFECT (CROSS REFERENCE ANALYSIS ON WEB: HTTP://TECHNO-FANDOM.ORG/~HOBBIT/CARS/MFD/COMPARE.HTML AND HTTP://TECHNO-FANDOM.ORG/~HOBBIT/CARS/MFD/). TOYOTA ISSUED A TECHNICAL SERVICE BULLETIN (EITHER EL-002-04 OR EL-002-05 - CONFLICTING INFO ON THIS) ON JAN 10, 2005. WHEN THE MFD FAILS, ONE CANNOT CONTROL THE AMOUNT OF AIRFLOW TO THE WINDSHIELD (DEFROSTER). THIS PRESENTED ME WITH VISIBILITY PROBLEMS DURING THE MORNING COMMUTE. AS SUCH, I CONSIDER IT A SAFETY ISSUE. TOYOTA HAS BEEN AWARE OF THIS FOR 3 YEARS, GIVEN THE DATE OF THEIR TSB. THE ROOT CAUSE APPEARS TO BE AN UNDERSIZED SOLDER PAD ON ONE OF THE ELECTRONIC CARDS OF THE MFD. THIS RESULTS IN A CRACKING OF THE SOLDER JOINT. BECAUSE MY PROBLEM WAS INTERMITTENT, COMING AND GOING ON A FREQUENT BASIS, I PRESUME IT WAS A MICRO CRACK. THIS DOES NOT HELP WHEN THE WINDSHIELD IS FOGGING OVER. ALL OF THE VARIOUS ERROR MESSAGES THAT WERE DISPLAYED ON THE MFD WERE CONSISTENT WITH THE INFORMATION ON THE ABOVE REFERENCED WEB URL'S. THE PROBLEM IS WITH THE RELEASE F OF THE ELECTRONIC CARD ASSEMBLY AND WAS CORRECTED WITH RELEASE G. THERE ARE PICTORIAL COMPARISONS BETWEEN THE TWO RELEASES ON ONE OF THE WEB URL'S. GIVEN THAT THIS HAS AN IMPACT ON VISIBILITY DURING THE WINTER MONTHS, I AM SHOCKED THAT TOYOTA CHOSE TO SIT ON THIS PROBLEM. THE SUPPLIER OF THIS PART TO TOYOTA IS FUJITSU. *TR
