THIS IS THE SECOND INCIDENT I'VE EXPERIENCE WITH AN ENGINE SURGE AND UNINTENDED ACCELERATION. I WAS DRIVING APPROX. 25MPH TOWARDS AN INTERSECTION. THE LIGHT AHEAD WAS RED, SO I TOOK MY FOOT ENTIRELY OFF OF THE ACCELERATOR AND LET THE CAR COAST. IT GRADUALLY SLOWED DOWN AS IT ALWAYS DOES, NOTHING UNUSUAL. AS I CAME UP ON THE RED LIGHT I APPLIED THE BRAKES AND ROLLED TO A SOFT STOP. I WAITED AT A RED LIGHT WITH MY FOOT RESTING ENTIRELY ON THE BRAKE PEDAL. ALL OF A SUDDEN--THE FIRST THING I NOTICED WAS THE SOUND--THE ENGINE ROARED AND THE CAR TRIED TO RACE FORWARD DESPITE MY FOOT ON THE BRAKE. I PRESSED HARDER ON THE BRAKE TO NO AVAIL. THE CAR WAS FIGHTING AGAINST ME WANTING TO RACE FORWARD. THERE WAS A STOPPED CAR AHEAD OF ME AND I WAS TRYING NOT TO CRASH INTO IT. IN DESPERATION I STOOD UP ON THE BRAKES AS HARD AS I COULD AND THE CAR SKID. I HAD TO STEER INTO ONCOMING TRAFFIC TO AVOID REAR ENDING THE CAR IN FRONT OF ME. I PULLED THE EMERGENCY BRAKE AND THE CAR CAME TO A STOP DIAGONAL ACROSS TWO LANES OF TRAFFIC. I BROUGHT THE CAR INTO TOYOTA FOR A SECOND TIME. DEALER RAN EXTENSIVE TESTS ON ELECTRONIC AND ENGINE SYSTEMS AND SAID THERE WAS NOTHING WRONG. THEY STATED THAT THE COMPUTER "HISTORY" SHOWED NO RECORD OF THE INCIDENT. THEY OFFERED NO EXPLANATION NOR ANY REMEDY. I AM FRUSTRATED BEYOND BELIEF THAT TOYOTA IS HIDING BEHIND "WE CAN'T FIND ANYTHING WRONG" AND IS NOT TRYING HARDER TO FIND THE CAUSE. THERE ARE NO FLOOR MATS IN MY CAR, AND THERE ARE NO PROBLEMS WITH THE GAS PEDAL. I WOULD LIKE TO MAKE VERY CLEAR THAT MY FOOT WAS ENTIRELY OFF OF THE GAS PEDAL FOR AT LEAST 15 SECONDS PRIOR TO THE FAILURE. I AM CONVINCED THAT THIS INCIDENT WAS CAUSED BY A COMPUTER MIS-FIRE OR ELECTRONIC MALFUNCTION THAT CAUSED THE ENGINE TO OPEN FULL-THROTTLE WHILE THE CAR WAS STOPPED AND BRAKES ENGAGED. TOYOTA DOES NOT KNOW WHAT IS WRONG, AND THEY DON'T KNOW HOW TO FIX IT --THIS IS A HUGE PROBLEM! PEOPLES LIVES ARE AT STAKE! *TR

I PUSHED THE BRAKE PEDAL A FEW TIMES, BUT THE BRAKING SYSTEM WAS NON-RESPONSIVE. I REALIZED I WOULD SOON BE APPROACHING THE CAR AHEAD OF ME, SO I LOOKED IN MY MIRRORS AND OVER BOTH SHOULDERS TO DETERMINE THE LOCATIONS OF OTHER VEHICLES. I WANTED TO CHANGE LANES SO THAT I HAD MORE TIME TO ATTEMPT OTHER CORRECTIVE ACTIONS. WHEN I BEGAN THE LANE CHANGE AND WHILE MY VEHICLE WAS CONTINUING TO ACCELERATE, THE VEHICLE SPUN OUT AND I HIT THE CENTER DIVIDE HEAD-ON. THE ACCIDENT STALLED THE MOTOR.

2006 TOYOTA COROLLA "S" / 52760 MILES I WAS DRIVING ON A CITY STREET AND APPROACHING A RED STOP LIGHT, I APPLIED THE BRAKES AND WAS NEARLY AT A COMPLETE STOP (COULD NOT HAVE BEEN GOING MORE THAN 2-3MPH). ALL OF A SUDDEN WITHOUT WARNING, THE ENGINE SURGED AND THE CAR LURCHED FORWARD--DESPITE THE FACT THAT I THE BRAKES WERE BEING PRESSED. I IMMEDIATELY PRESSED HARDER ON THE BRAKES AND GOT NO REACTION, SO I JAMMED BOTH FEET ON THE BRAKE PEDAL AS HARD AS I COULD, THE WHEELS LOCKED AND I SKID APPROXIMATELY 10 FEET! I HAD TO STEER OUT OF THE WAY OF REAR-ENDING THE STOPPED CAR AHEAD OF ME. ALL OF THIS HAPPENED IN ABOUT A THREE SECOND TIME FRAME. IT WAS LITERALLY A MIRACLE THAT I DID NOT RAM INTO THE CAR AHEAD OF ME. ONCE THE CAR CAME TO A STOP, EVERYTHING SEEMED NORMAL AGAIN, AND THE CAR DROVE FINE AS IF NOTHING EVER HAPPENED. I AM THE ORIGINAL OWNER AND SOLE DRIVER OF THIS CAR AND HAVE NEVER EXPERIENCED ANYTHING LIKE THIS. IT WAS AS IF SOME OUTSIDE FORCE HAD CONTROL OVER THE CAR AND I COULD NOT STOP IT. THIS COULD HAVE CAUSED SERIOUSLY INJURY OR DEATH. I IMMEDIATELY CALLED MY TOYOTA SERVICE DEPT. AND THE TECHNICIAN I SPOKE TO TOLD ME HE "NEVER HEARD OF SUCH A THING" OR THAT "MAYBE PERHAPS THE FLOOR MAT WAS INVOLVED". I CURRENTLY HAVE NO FLOOR MATS IN THIS VEHICLE SO THAT WAS NOT THE CAUSE. I AM BRINGING THE CAR INTO TOYOTA. HOWEVER IN RESEARCHING THIS INCIDENT ONLINE, I AM NOT THE ONLY PERSON WHO HAS EXPERIENCED THIS SUDDEN LURCHING AND LOSS OF CONTROL. TOYOTA NEEDS TO ADDRESS THIS NOW! *TR

SUDDEN ACCELERATION AT HIGHWAY SPEEDS IN 2006 TOYOTA COROLLA - ON 11-24-09 TRAVELING SOUTH ON HIGHWAY 5 IN CALIFORNIA NEAR BUTTONWILOW AT APPROXIMATELY 70-75 MILES PER HOUR IN THE FAST LANE, PROBABLY WHILE ON CRUISE CONTROL, CAR BEGAN TO ACCELERATE, HIT THE BRAKE WHICH HAD NO EFFECT, AND IF IT HAD BEEN ON CRUISE CONTROL, IT DID NOT OVERRIDE THE ACCELERATION. I BEGAN TO GET CLOSER TO THE CAR IN FRONT OF ME. I DO NOT BELIEVE I INITIALLY TRIED TO PUT THE CAR INTO NEUTRAL. I TURNED OFF THE CAR ENGINE, THE ACCELERATION STOPPED, I HIT THE BRAKE SOMEWHAT TO GET IT DOWN TO A REGULAR SPEED, PUT THE CAR INTO NEUTRAL, STARTED IT WHILE COASTING, PUT IT BACK INTO GEAR (MANUAL TRANSMISSION), AND THE CRISIS WAS OVER. THEN, ABOUT AN HOUR LATER, WHILE ON THE GRAPEVINE PORTION OF HWY 5 AFTER THE SUMMIT, IT DID THE SAME THING WITH LESSER TRAFFIC. I PUT IT INTO NEUTRAL THIS TIME, HIT THE BRAKE, SLOWED A LITTLE, PUT IT BACK INTO GEAR AND SINCE THEN IT HAS NOT OCCURRED. SEE NEXT PARAGRAPH. OVER THE PAST 3 YEARS, THEIR HAVE BEEN A NUMBER OF ADDITIONAL OCCASIONS WITH A DIFFERENT ISSUE WHERE: 1) MY FOOT HAS SLIPPED OFF THE BRAKE ONTO THE ACCELERATOR CAUSING THE ENGINE TO REV WHEN IN NEUTRAL IN THE DRIVEWAY OR A STOPLIGHT (I THINK BECAUSE THE PEDALS ARE SMALL AND VERY CLOSE TO ONE ANOTHER), AND; 2) OCCASIONS WHEN THE ACCELERATOR HAS GOT STUCK UNDER THE FLOORMAT WHEN THE FLOORMAT HAD SLID FORWARD CAUSING THE CAR TO ACCELERATE.

4EA21002 · 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.

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).

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.

On November 30, 2009, the Office of Defects Investigation (ODI) opened a preliminary evaluation (PE09-054) to investigate alleged engine stalling, while driving in model year (MY) 2006 Toyota Corolla and Corolla Matrix vehicles .In its response to ODI's information request submitted on March 2, 2010, Toyota indicated that it had identified two possible causes of production defects of the engine control units (ECU) used in the MY 2005 through 2007 Corolla and Matrix vehicles equipped with the 1ZZ-FE engine.Failure mode A1 - BGA ball failure caused by improperly cured conformal coating applied to ECU circuit boards. This can cause cracks to form in the soldered joints of some components. Failure mode A2 - Varistor over heating; a glass coating is created on the surface of the Varistor during its production process.In case of an insufficient coating, a crack can occur in the surface of the glass coating. When ions are charged in the plating electrolytes after the glass coating process, the plating electrolytes can penetrate into the Varistor through the glass crack then an electrical short occurs. With respect to these failures, if the condition arises, it can potentially lead to one or more of the following: MIL on, engine stall or engine no start, harsh shifting.Of the approximately 155,000 warranty and extended warranty claims Toyota has analyzedthe projected 5 year failure rate of the ECU associated with an engine stall is 0.8%. This investigation has been upgraded to an Engineering Analysis (EA10-006) to further assess the scope, frequency and safety risks associated with the identified defects.
