NHTSA Complaint #10332367 — 2004 TOYOTA PRIUS

DRIVING HOME AT NIGHT ON THE 405 FREEWAY AT APPROX. 65MPH, SUDDENLY ALL THE DASH WARNING LIGHTS ILLUMINATED, INCLUDING THE MIL SYMBOL, ALONG WITH A WARNING SYMBOL ON THE NAVIGATION SCREEN. I PULLED OFF THE FREEWAY AND PARKED AT THE CURB. AFTER CHECKING THE OWNERS MANUAL, I SLOWLY DROVE THE REST OF THE WAY HOME ON SURFACE STREETS. THE NEXT MORNING (MONDAY) I DROVE MY CAR TO MILLER TOYOTA IN CULVER CITY. THE PRIMARY DIAGNOSIS WAS FAILURE OF THE INVERTER COOLANT PUMP, WHICH WAS REPLACED UNDER THE TERMS OF MY TOYOTA PLATINUM EXTENDED WARRANTY. HOWEVER, UPON FURTHER RESEARCH, I DISCOVERED THAT TOYOTA HAD ISSUED A TECHNICAL SERVICE BULLETIN (TSB) COVERING THIS VERY PART, ON JANUARY 26, 2007, INDICATING THAT THEY WERE AWARE OF THIS FAILURE-PRONE PART, AND THAT AN "IMPROVED" REPLACEMENT ASSEMBLY WAS NOW AVAILABLE TO ADDRESS THE ISSUE. IN ADDITION, REPLACEMENT WOULD BE COVERED UNDER THEIR 5-YEAR/60,000 MILE TOYOTA POWERTRAIN WARRANTY. APPROXIMATELY ONE MONTH LATER, ON MAY 15, 2010, WHILE DRIVING MY FATHER'S 2004 PRIUS TO HAVE NEW TIRES INSTALLED, THE SAME SEQUENCE OF EVENTS OCCURRED. I IMMEDIATELY DROVE THE VEHICLE TO THE NEAREST DEALER, SANTA MONICA TOYOTA, WHERE IT WAS DIAGNOSED WITH THE SAME FAILURE CODE, P0A93 (INVERTER COOLING SYSTEM PERFORMANCE). ALTHOUGH THE VEHICLE HAD ONLY 34,242 MILES ON IT, IT WAS NOT COVERED UNDER THE POWERTRAIN WARRANTY, AS THE TIME LIMIT OF 60 MONTHS HAD EXPIRED. NO AMOUNT OF DISCUSSION WITH THE DEALER OR TOYOTA'S CUSTOMER EXPERIENCE CENTER COULD CONVINCE THEM THAT THIS PART SHOULD BE CONSIDERED PART OF THE HYBRID SYSTEM, AND AS SUCH BE COVERED UNDER THEIR 7-YEAR/100,000 HYBRID WARRANTY (DESPITE IT BEING NAMED THE HYBRID INVERTER COOLANT PUMP). ON-LINE PRIUS-RELATED CHAT ROOMS ARE FULL OF IDENTICAL SITUATIONS INVOLVING THIS PART. CLEARLY, TOYOTA KNOWS THIS PART IS PRONE TO PREMATURE FAILURE, BUT CONTINUES TO TREAT IT AS A "SECRET WARRANTY" ITEM IN ORDER TO AVOID HAVING TO ISSUE A FORMAL RECALL. *TR
