SHORTLY AFTER PURCHASING MY 2014 TOYOTA PRIUS IN JUNE 2014, I STARTED NOTICING A MOLDY SMELL COMING FROM THE AIR CONDITIONER. THE HOTTER OUTSIDE IT GOT, THE WORSE THE SMELL INSIDE GOT. I TOOK THE CAR TO THE DEALER TO DISCUSS THE PROBLEM WITH THEM. THEY INFORMED ME THAT TOYOTA SAYS THIS IS AN "ENVIRONMENTAL ISSUE" AND CAN HAPPEN IN NEW CARS AND IS THEREFORE NOT WARRANTIED. THE SERVICE MANAGER INSTALLED A CHARCOAL AIR FILTER IN THE CABIN AIR FILTER AND SAID THAT IT WOULD HELP ELIMINATE THE ODOR. IT DID NOT. IN FACT, THE CHARCOAL AIR FILTER REDUCED THE AIR FLOW INTO THE CABIN WHICH CAUSED THE AC TO NOT COOL. I HAD THE SERVICE DEPARTMENT REPLACE THE CHARCOAL WITH AN ORIGINAL AIR FILTER IN SEPTEMBER AFTER COMPLAINING THAT THE AC WASN'T COOL. THE SMELL IN THE AC PERSISTS. IT'S NOT JUST A BIT WHEN THE CAR IS TURNED ON. NO MATTER WHAT SETTING I PUT THE AC ON, IT DOES NOT HELP (FRESH AIR OR RECIRC). WHEN IT RAINS OR WHEN IT IS REALLY HUMID OUTSIDE, THE CAR SMELLS LIKE A SWAMP (EVEN BEFORE IT IS TURNED ON). THERE IS ALSO HUMIDITY INSIDE THE CAR WHEN OPENING THE DOOR. I'VE ASKED MULTIPLE TIMES TO HAVE THE EVAPORATOR REPLACED BECAUSE I FEAR THAT IT IS NOT DRAINING AND CAUSING MOLD AND MILDEW TO FORM. BREATHING IN THE MOLD IS A SERIOUS HEALTH CONCERN AND TOYOTA WILL NOT AGREE TO ANY KIND OF FIX. I'M ALSO HAVING OTHER VARIOUS HVAC PROBLEMS SUCH AS CONTINUOUSLY FOGGING WINDOWS AND A DRAFT FROM THE DRIVERS SIDE DOOR. THE CAR DOES NOT HOLD HEAT AND IS VERY COLD DURING THE WINTER MONTHS. *TR

THE LEFT SIDE HAD SOME SORT OF CIRCULAR EFFECT THAT NEGATIVELY EFFECTS MY VISION. THE DEALER ATTEMPTED TO TREAT THE WINDSHIELD WITH RAIN X AS SOME SORT OF FIX. THIS DID NOT HELP. THIS WAS A VERY UNPROFESSIONAL FIX. IN FACT, I BELIEVE THE RAIN X MADE THE PROBLEM WORSE. I DON'T REMEMBER THE ISSUE OCCURRING UNTIL A FEW WEEKS AFTER THE INITIAL PURCHASE OF THE VEHICLE.

I PURCHASED THE VEHICLE BRAND NEW FROM A DEALERSHIP. WITHIN A FEW WEEKS, I NOTICED THAT WHEN MY HUSBAND SAT IN THE FRONT PASSENGER SEAT (300LBS) THE NOTIFICATION LIGHT SAID "PASSENGER AIR BAG ON". WHEN MY STEPSON SAT IN THE FRONT PASSENGER SEAT THE LIGHT SAID "PASSENGER AIR BAG OFF". I TOOK A PICTURE TO SHOW THE NOTIFICATION LIGHT AND THE SIZE OF MY 15 YR OLD STEPSON 5' 10" & 175LB-FULLY ADULT SIZE. I CALLED THE DEALERSHIP AND THEY TOLD ME THEY HAD "NEVER HEARD OF THE PROBLEM" AND SAID IT WAS JUST THAT THE PASSENGER AIRBAG NEEDED TO BE RECALIBRATED. AFTER DOING SOME SEARCHING, I REALIZED THAT THE 2012-2013 MODELS HAVE ALREADY BEEN RECALLED FOR THAT EXACT SAME REASON. I AM VERY CONCERNED THAT THE PROBLEM HAS NOT BEEN FIXED WITH TOYOTA, AND THAT NEW CARS ARE BEING SOLD WITH THE SAME PROBLEM. NEEDLESS TO SAY, I AM NOT HAPPY WITH TOYOTA RIGHT NOW AND THIS IS A HUGE SAFETY PROBLEM. I ALSO HAVE CONCERNS ABOUT THE BACK SEAT BELTS NOT LATCHING PROPERLY WHEN A CAR SEAT IS BEING USED, BUT THAT'S ANOTHER STORY.... *TR

WE PURCHASED A NEW TOYOTA PRIUS THAT CAME WITH YOKOHAMA ALL SEASON RADIALS. BECAUSE THE TIRE LIGHT CAME ON, I CHECKED THE AIR PRESSURE IN THE TIRES AND SET THEM TO THE PSI AS RECOMMENDED AT ABOUT 1000 MILES. THERE WAS A MINOR IMBALANCE OF 3-4 PSI IN SOME TIRES, BUT NO SERIOUS UNDER INFLATION. WE NOTICED SOME MINOR ROAD NOISE AND VIBRATION. WE HAD A MECHANIC INSTALL MUD FLAPS AND INSPECT THE TIRES, WHEELS, AND BRAKES AT ABOUT 1500 MILES TO SEE IF THERE WAS A VISIBLE REASON FOR VIBRATION. THERE WAS NOTHING OBVIOUS. WE WERE CONCERNED ABOUT THE ROAD NOISE AND ABOUT 2000 MILES WE TOOK THE CAR BACK TO THE TOYOTA DEALER WHO INSPECTED THE TIRES, CHECKED THE AIR PRESSURE, AND DECLARED THAT THEY DIDN'T SEE ANYTHING WRONG. AT ABOUT 3000 MILES DRIVING AT A SLOW SPEED (35 MPH OR LESS) IN A SCHOOL ZONE, WE HAD A COMPLETE BLOW OUT OF THE LEFT REAR TIRE. FORTUNATELY, THERE WAS A GRASSY SHOULDER AND NO TRAFFIC, SO WE HAD NO INJURIES OR OTHER DAMAGE. THE TREAD APPEARED TO SEPARATE AND THERE WAS A SIDEWALL TEAR STARTING AT THE TREAD. WE RETURNED TO THE TOYOTA DEALER AND ALSO SHOWED THE TIRE TO THREE DIFFERENT TIRE SHOPS (ALL THREE SELL YOKOHAMA TIRES). THE TOYOTA DEALER DID NOT OFFER AN OPINION OTHER THAN TIRE DEFECT - SO WE NEEDED TO DEAL WITH THE MANUFACTURER. TWO TIRE SHOPS THOUGHT IT WAS A DEFECT (EVEN THOUGH THEY SAID IT WAS A HASSLE TO GET A REPLACEMENT PAID FOR BY YOKOHAMA). ONE SHOP REPORTED IT WAS A DEFECT UNLESS THE TIRE WAS UNDER INFLATED, BUT THEY DIDN'T SEE ANY WEAR PATTERN THAT INDICATED UNDER INFLATION. BECAUSE OF THE BLOWOUT AND A SECOND SUSPICIOUS TIRE OF THE FOUR, WE REPLACED ALL FOUR WITH A DIFFERENT BRAND. AS FAR AS WE CAN TELL, THE YOKOHAMA TIRE(S) WERE DEFECTIVE AS NEW ON THE CAR. *TR

14V053000 · Electrical System:software; Hybrid Propulsion System: Inverter

Feb 12, 2014

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

DP19004 · Brake Actuator Valve Wear

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
