WHEN YOU APPLY THE BRAKES WITH FULL FORCE WHILE DRIVING; THE BRAKES LOCK UP FOR A SHORT PERIOD OF TIME ON ONE SIDE OF THE VEHICLE, CAUSING THE VEHICLE TO SWERVE UNCONTROLLABLY. THIS IS EXTREMELY DANGEROUS VEHICLE WHEN THE BRAKES ARE APPLIED WITH HARD FORCE AT SPEEDS AT AROUND 35 MPH OR HIGHER. LUCKILY I AM A VERY EXPERIENCED DRIVER AND CAR HANDLER AND WAS ABLE TO REACT QUICK ENOUGH TO CONTROL THE VEHICLE ONE TIME WHEN I HAD TO APPLY THE BRAKES HARD AT HIGHWAY SPEEDS WHEN A CAR SWERVED IN FRONT OF ME SUDDENLY. I HAVE SINCE DONE MANY TESTS ON THIS VEHICLE MYSELF AND CONCLUDED THAT ONE WHEEL ON THE LEFT SIDE OF THE VEHICLE IS LOCKING UP WHICH IS CAUSING THE VEHICLE TO QUICKLY AND VIOLENTLY SWERVE. THE TEST I DID WAS TO APPLY THE BRAKES VERY HARD AND SUDDENLY WHILE DRIVING ON A FLAT GRASSY FIELD AT 35 MPH. THE GRASS IN THE FIELD HAD BEEN CUT A FEW DAYS EARLIER AND WAS AT A HEIGHT OF ABOUT 4 INCHES AND DRY, THE AIR TEMPERATURE WAS 82 DEGREES F. AFTER APPLYING THE BRAKES HARD, I WOULD STOP THE VEHICLE AND GO BACK AND LOOK AT THE PATH OF THE VEHICLE WHERE THE BRAKES WERE APPLIED. THERE WAS CLEARLY A PATCH OF GROUND THE SAME WIDTH AS THE TIRE, EXPOSED DOWN TO ABOUT ONE INCH BELOW SURFACE WITH NO GRASS, WHERE THE ONE WHEEL THAT LOCKED UP, SKIDDED AND RIPPED THE GRASS AND DIRT UP. I HAVE DONE THIS TEST MULTIPLE TIMES AND BASED ON MY RESULTS HAVE CONCLUDED THAT ONE WHEEL ON THE LEFT SIDE IS LOCKING UP. I DID NOT THAT IF I REPEAT THE TEST SEVERAL TIMES BACK TO BACK, THE PROBLEM SEEMS TO CORRECT ITSELF AT TIMES. BUT ALWAYS ON THE INITIAL TEST, THE LOCK UP OCCURS. I HAVE HAD IT TO TWO DIFFERENT TOYOTA DEALERS AND THEY BOTH TOLD ME THAT THE BRAKES ARE WORKING AS DESIGNED. IF YES, THIS IS A VERY DANGEROUS DESIGN AND I DON'T FEEL SAFE AT ALL, AND I ALSO NOTICED THAT THERE ARE SEVERAL OTHER COMPLAINTS ABOUT THE BRAKES FOR THIS 4RUNNER MODEL YEARS.

WHEN YOU GET A RECALL IT'S TO FIX THE PROBLEM, THEREFORE IF MY CAR NEEDS A NEW GRILL TO SUPPORT WHAT THEY NEED TO DO, THEN DEALERSHIP SHOULD PAY FOR WHATEVER IT IS TO FIX THE RECALL.

TOYOTA ENTUNE (IPHONE APP) WILL NOT PAIR WITH YOUR PHONE OR DISCONNECTS DURING USE BECAUSE APP DOES NOT MAINTAIN THE USER'S LOGIN CREDENTIALS. THE BEHAVIOR OF THE CONNECTIVITY BETWEEN THE VEHICLE'S ENTERTAINMENT SYSTEM AND PHONE IS DIFFICULT TO PREDICT, SOMETIMES THE SYSTEM WON'T WORK WITHOUT THE PHONE'S APP RUNNING AND OTHER TIMES IT WILL - SOMETIMES IT WON'T WORK EVEN WHEN THE APP IS RUNNING. OFTEN, WHEN THE ENTERTAINMENT SYSTEM FAILS TO CONNECT IT STOPS FUNCTIONING AND POPS UP MESSAGES THAT REQUIRE USER INPUT WHILE DRIVING. MANY TIMES THE PHONE APPEARS TO BE CONNECTED UNTIL AFTER YOU START DRIVING AND THEN THE SYSTEM ASKS FOR INPUT (WHICH YOU MUST DO ON YOUR PHONE, NOT THE ENTERTAINMENT SYSTEM'S SCREEN). THE WHOLE POINT OF CONNECTING YOUR PHONE WITH THE VEHICLE'S ENTERTAINMENT SYSTEM IS TO ELIMINATE THE NEED TO USE YOUR PHONE WHILE DRIVING, SO A SEAMLESS CONNECTION WITHOUT UNNECESSARY USER INPUT IS IMPERATIVE TO SAFE OPERATION OF THE SYSTEM. THIS IS ADMITTEDLY A RELATIVELY MINOR SAFETY CONCERN, HOWEVER A FIX WOULD BE REMARKABLY EASY TO ACHIEVE AND WOULD GO A LONG WAY TOWARDS REDUCING DRIVER DISTRACTION. TOYOTA VEHICLE OWNERS HAVE BEEN ASKING FOR THIS FUNCTIONALITY FOR MANY YEARS (SEE APPLE APP STORE REVIEWS FOR TOYOTA ENTUNE), BUT, DESPITE MULTIPLE REQUESTS, TOYOTA MOTOR COMPANY HAS REPEATEDLY IGNORED THEIR CUSTOMERS. THIS PROBLEM OCCURS ACROSS MULTIPLE VEHICLES IN THE TOYOTA LINEUP, BUT I AM ONLY FAMILIAR WITH THE IPHONE APP, SO I'M NOT SURE IF IT ALSO EXISTS WITH OTHER PHONES. THE ISSUE HAS OCCURRED CONSISTENTLY SINCE WE PURCHASED THE VEHICLE A YEAR AGO AND PERSISTS DESPITE KEEPING BOTH PHONE SOFTWARE AND VEHICLE FIRMWARE UPDATED.

NOTHING HIT THE WINDOW, AND I HADN'T HIT A POTHOLE OR ANY BUMP IN THE ROAD, THERE ALSO WAS NO EXTREME CHANGE IN TEMPERATURES ' IT JUST EXPLODED INTO MANY PIECES INCLUDING SMALL SHARDS OF GLASS. THE GLASS WENT ALL OVER THE INSIDE OF MY CAR INCLUDING BOTH FRONT AND BACK SEATS AND FLOORBOARDS. THE ENTIRE WINDOW EXPLODED SO THAT THERE WAS NO WINDOW LEFT IN THE OPENING. I BELIEVE IT WAS FAULTY GLASS. I UNDERSTAND THAT THERE HAVE BEEN SUNROOFS EXPLODING, AND I BELIEVE THAT THE GLASS ISSUE IS NOT JUST LIMITED TO THE SUNROOF. I DID SAVE THE RECEIPT FROM HAVING THE GLASS REPLACED, BUT I DON'T CURRENTLY HAVE THE ABILITY TO SCAN AND ATTACH IT.

WHEN I PICKED UP THE VEHICLE, THEY SAID THEY TALKED WITH TOYOTA AND IT WAS ONLY THE 2ND CASE OF THIS HAPPENING IN THE US. THE MORNING IT HAPPENED IT WAS AROUND 30 TO 35 F OUTSIDE.

1EA21002 · 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.
