MY CONCERN IS THE DEAD ZONE CREATED BY THE HEAD LIGHTS ON MY CAR. THE PROJECTION OF THE HEADLIGHTS ON MY CAR ARE EXTREMELY DANGEROUS DUE TO THE DEAD ZONE IN FRONT OF THE VEHICLE. THE HEADLIGHTS HAVE BEEN ADJUSTED MULTIPLE TIMES AND THE DEALER RESPONSE IS" THAT IS JUST THE WAY THESE NEW HEADLIGHTS ARE". ON DARK ROADS IT IS HIGHLY PROBABLE THAT AN ACCIDENT MAY OCCUR BECAUSE YOU CANNOT SEE WHERE YOU ARE GOING AND IF THERE IS A SLIGHT CURVE TO THE ROAD IT IS IMPOSSIBLE TO TELL WHICH WAY THE ROAD IS GOING. ON MY LAST TRIP AT NIGHT WE HAD 3 OCCASIONS THAT IF WE HAD NOT FLASHED THE HIGH BEAMS WE MOST CERTAINLY WOULD HAVE A WRECK. *TR

FAILURE OF DRIVER'S CABIN LAMP OVERRIDE SWITCH TO EXTINGUISH CABIN READING LIGHTS OBSCURED DRIVER'S VISION AT NIGHT DURING HIGH-SPEED MERGE MANEUVER: I WAS ATTEMPTING A HIGH-SPEED HIGHWAY MERGE, AT NIGHT, ENTERING ROUTE 29 FROM THE LEFT SIDE OF THE HIGHWAY, WHEN MY THREE-YEAR-OLD SON DISCOVERED THAT HE WAS NOW TALL ENOUGH TO OPERATE HIS OVERHEAD PERSONAL READING LIGHT. MY VISION OF MERGING TRAFFIC TO THE RIGHT WAS SUDDENLY OBSCURED BY THE UNEXPECTED OPERATION OF THE CABIN READING LAMP, AND THE SITUATION WAS COMPOUNDED BY MY INABILITY TO QUICKLY OVERRIDE THE LAMP FROM THE DRIVER'S POSITION, IN THE MANNER AS DIRECTED ON PAGE 526 OF THE OWNER'S MANUAL. THE READING LIGHT ABOVE MY SON'S HEAD STAYED ON. ACCORDING TO THE SIENNA 2011 OWNER'S MANUAL ON PAGE 526, THE DOOR LIGHT BUTTON, ABOVE THE DRIVER'S HEAD, ALSO SERVES AS AN OVERRIDE FOR ALL THE PERSONAL CABIN READING LIGHTS WHEN THE "DOOR" FUNCTION IS DISABLED: PAGE 526: "REAR ON/OFF: REAR PERSONAL/INTERIOR LIGHTS TURN ON [UPON ACTIVATION OF THE ILLUSTRATED INDIVIDUAL READING LAMP BUTTONS AT EACH SEATING POSITION] WHEN THE PERSONAL/INTERIOR MAIN SWITCH IS IN DOOR POSITION." THE DUAL FUNCTIONALITY OF THE DOOR LIGHT BUTTON IS CONFIRMED; ON PAGE 525 OF THE MANUAL, THE OTHER WELL-KNOWN PURPOSE OF THE DOOR BUTTON IS SEPARATELY AND INDEPENDENTLY DESCRIBED TO ACTIVATE AUTOMATIC CABIN ILLUMINATION WHEN ENTERING/EXITING THE VEHICLE: PAGE 525: "DOOR POSITION: THE PERSONAL/INTERIOR LIGHTS AND REAR INTERIOR LIGHT COME ON WHEN A DOOR IS OPENED. THEY TURN OFF WHEN THE DOORS ARE CLOSED." THEREFORE, THE REFERENCE TO THE DOOR BUTTON ON PAGE 526 IS FOR THE SEPARATE OVERRIDE FEATURE. THANK YOU FOR YOUR CONSIDERATION. I RECOMMEND TOYOTA RECALL THE AFFECTED VEHICLES, TO CORRECT THE FUNCTIONING OF THE CABIN LAMP OVERRIDE SWITCH AS THIS IS AN ESSENTIAL SAFETY FEATURE OF THE VEHICLE FOR NIGHTTIME DRIVING WITH PASSENGERS.

5 MONTH OLD TOYOTA SIENNA 2011 STALLED AFTER THE LIGHTS INSIDE THE DASHBOARD (CONTROL PANEL) STARTED BLINKING AND THEN WOULD NOT START AGAIN. IT WAS TOWED TO THE DEALER ON 12/22/2010. DEALER INITIALLY (ON 12/27/2010) SAID IT IS DUE TO WATER DAMAGE AND ENGINE HAS TO BE REPLACED. DEALER WAS NOT ABLE TO FIND ANY EVIDENCE OF SIENNA BEING SUBMERGED IN WATER (AS IT DID NOT GO INTO ANY BIG PUDDLE OR DEEP WATERS). I OPENED A CASE WITH TOYOTA ON 12/28/2010. I WAS IN TOUCH WITH TOYOTA DEALER BUT CASE MANAGER AT TOYOTA INFORMED THAT THEY WERE UNABLE TO REACH/SPEAK TO THE DEALER FOR 2 DAYS EVEN THOUGH THEY ARE BOTH IN CALIFORNIA. SHE INFORMED ME THAT THEIR POLICY IS TO CONCUR WITH DEALER WITHOUT EVEN LOOKING AT THE REPORT OR TALKING TO THEM AND THEY WOULD NEITHER INVESTIGATE NOR INSPECT. MY INSURANCE COMPANY (AAA) PERFORMED VISUAL INSPECTION AND FOUND TOO MANY METAL PIECES INSIDE THE ENGINE. INSURANCE COMPANY ALSO FOLLOWED UP WITH DEALER AND INFORMED THERE ARE OTHER CASES WHERE THEY HAD SEEN SIMILAR ISSUE WITH TOYOTA SIENNA 2011 AND THIS DOES NOT SEEM TO BE A WATER DAMAGE. THERE HAS BEEN NEITHER AN EXPLANATION NOR A FOLLOW-UP FROM TOYOTA AS TO WHAT THE CAUSE WAS. DEALER REPORTED BACK ON 01/04/2011 AND INFORMED ME THAT IT MIGHT BE A MECHANICAL FAILURE AND TOYOTA WILL FIX IT. I AM NOW CONCERNED ABOUT THE SAFETY OF MY FAMILY AND ANYONE WHO DRIVES SIENNA. WHAT IF STALLS IN THE MIDDLE OF FREEWAY ? WHAT IF THIS HAPPENS AGAIN ? WORRIED AND TENSED OWNER OF TOYOTA SIENNA 2011.

SO I RENTED A NEW 2011 TOYOTA SIENNA LE (ONLY 900+ MILES) FROM AVIS FOR A WEEKLONG TRIP (1500 MILES). THE CAR DRIVES VERY NICELY. HOWEVER, I WAS AMAZED THAT I COULD NOT HEAR THE TURN INDICATOR BEEPER WHEN DRIVING DOWN THE INTERSTATE WITH THE RADIO ON AT A MODERATE SOUND LEVEL. IN ADDITION, THE TURN INDICATOR SWITCH IS NOT SENSITIVE ENOUGH TO DISENGAGE AFTER CHANGING LANES. TOYOTA'S DESIGN ENGINEERS SHOULD BE ASHAMED TO HAVE THIS SERIOUS DESIGN FLAW ON A NEWLY INTRODUCED VEHICLE! THERE ARE PLENTY OF AUDIBLE DEVICES ON THE VEHICLE THAT COULD SOUND AFTER THE TURN INDICATOR HAS BE ENGAGED FOR 5, 10, 15 SECONDS WITHOUT BEING DISENGAGED. TOYOTA COULD HAVE PROGRESSIVE AUDIBLE TONES, WITH A LAST RESORT OF SOUNDING THE HORN INTERMITTENTLY. JUST DO SOMETHING, BEFORE YOU HAVE MILLIONS OF THESE VEHICLES IN SERVICE. A CAR GOING DOWN THE ROAD WITH A 'FALSE TURN INDICATION' IS DANGEROUS TO EVERYONE ON THE HIGHWAY! AS A RESULT OF THIS EXPERIENCE I AM NOT GOING TO BUY A 2011 TOYOTA SIENNA LIMITED UNTIL THIS ISSUE IS RESOLVED. IN FACT, IT WOULD NOT BE BAD ADVERTISING FOR ALL TOYOTA VEHICLES TO HAVE THIS AS A STANDARD FEATURE. TOYOTA CAN GIVE ME NEW VEHICLES FOR THE REST OF MY LIFE, AS COMPENSATION FOR THE IDEA!

14V273000 · Tires:temporary/emergency Spare Tire

May 22, 2014

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2004-2011 Sienna vehicles originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier.

Consequence & remedy

Consequence: If the carrier cable is corroded due to road salt, the spare tire may separate from the vehicle, increasing the risk of a crash.

Remedy: Toyota sent owners in August 2014 an interim notification to advise owners of the recall and that dealers will perform an interim remedy to remove the spare tire and relocate it to the luggage compartment, free of charge. Owners are being mailed a second letter as parts become available and dealers will replace the spare tire carrier assembly with an improved one, free of charge. The remedy campaign is being performed in phases. The first phase of the recall began July 7, 2015. Owners may contact Toyota customer service at 1-800-331-4331. NOTE: 2004-2010 Siennas subject to this recall were subject to recall campaign 10V-160 initiated in 2010. Those owners are advised that they must have their vehicles remedied again under this campaign and that having the earlier recall completed did not remedy their vehicles. Additionally, model year 1998-2003 Siennas were recalled as part of safety recall 10V-160. Owners of those vehicles that have not had not the remedy performed on their vehicles, should contact their Toyota dealer to schedule a free repair.

These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. Thus, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) Number 110, "Tire Selection and Rims."

Consequence & remedy

Consequence: An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.

Remedy: Southeast Toyota will notify owners and provide a corrected label with instructions concerning its installation. A small group of the affected vehicles will need additonal remedies which are still being developed. The recall began on May 28, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

Jan 16, 2013

Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.

Consequence & remedy

Consequence: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
