1) The failed component is the door locks. Or more precisely, the motor for the electrical operation of the door locks. When failed, the door remains locked even when pulling on the interior handle to open the door or when trying to unlock the door using the interior latch. You are essentially locked inside your car. I believe the door should always unlock when the handle is pulled, and the interior lock lever should always unlock the door as well. Both of these function "normally" when the actuator is not failed. The failure first appeared in late 2018/early 2019. I noticed that when I locked the vehicle using the key fob, I was not hearing the audible "beep." And when the car was shifted out of PARK, I was not hearing all the doors lock. I then realized the drivers front door was not locking. I lived with this for a while, long enough for the drivers side rear door to fail, and then the right rear door failed as well. The front right and rear door have never failed. I purchased a Toyota lock assembly for the drivers side front and it functioned perfectly after replacement until this past week. It appears to have failed again. And I was essentially trapped in the drivers seat. I had to give it and electrical command to unlock while pushing on the manual lever in order for the door to unlock. Pulling the open handle did not open the door, and pushing on the manual lock lever did not open the lock. The failed component appears to be a small motor in the lock assy. I replaced this motor in the left and right rear door lock assembly's and that corrected the problem. I am going to replace the motor in the lock assy I removed in 2019 and reinstall it in hopes of correcting the problem. I can send you the Toyota lock assy I will remove, and one of the motors I removed from one of the rear door lock assembly's. 2)The failed door locks trap occupants inside the vehicle. 3)Did not visit a dealer or repair center. 4)No inspections have been performed. 5)No

MY VEHICLE WAS IN MOTION, AND THE ENGINE SHUT OFF. I WAS ABLE TO RESTART THE VEHICLE SEVERAL TIMES, BUT IT WOULD ONLY CONTINUE RUNNING FOR 5 TO 60 SECONDS. AFTER ABOUT 30 MINUTES THE VEHICLE STARTED AND DROVE TO MY DESTINATION (HOME). THE PROBLEM PERSISTED FOR 3 DAYS, WITH ONLY ONE SUCCESSFUL SHORT DRIVE AMIDST SEVERAL STALLS AND RESTARTS. EACH TIME THE VEHICLE STARTED, BUT DID NOT RUN FOR LONG BEFORE DYING. I TOWED IT TO MY LOCAL TOYOTA DEALERSHIP 9 DAYS AGO AND THEY WERE NOT ABLE TO FIND ANY ISSUE... THE PROBLEM SEEMS TO HAVE FIXED ITSELF, AT LEAST FOR NOW. HOWEVER, TODAY THE NEWS REPORTED A RECALL FOR NEWER MODEL 4 RUNNERS THAT HAVE A PROBLEM WITH THE FUEL PUMP CAUSING THE VEHICLE TO STALL WHILE DRIVING, POSING A SERIOUS RISK. I BELIEVE THIS MAY BE THE SAME ISSUE THAT IS AFFECTING MY 2013 4 RUNNER.

DEALER SAYS ONLY REMEDY IS A $125-$150 BRAKE FLUID CHANGE. 2) THE OUTSIDE TEMPERATURE GAUGE DOESN'T WORK, SO DON'T EXPECT TO BE ALERTED IN A TIMELY MANNER IF THE ROADS ARE READY TO FREEZE OVER AND BECOME ICY. DEALER CHECKED IT AND SAID IT WAS FINE, ITS NOT FINE. IT SEEMS TO BE USUALLY OFF BY 10 DEGREES AND OTHERWISE REACTS SO SLOWLY TO CHANGES IN TEMPERATURE SO AS TO BE USELESS. SOFT BRAKE PEDAL STARTED IN EARLY 2017. TEMPERATURE GAUGE HAS NEVER WORKED WELL.

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.

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).

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.
