THE CVT TRANSMISSION FAILED AT 79K MILES AT HIGHWAY SPEEDS CAUSING THE CAR TO VIOLENTLY STALL. WE BARELY AVOIDED HITTING THE CARS AROUND US TRYING TO PULL OVER. LUCKILY THERE WAS NO CAR TO REAR END US. WE WERE VERY LUCKY THE TRAFFIC WAS LIGHT. THESE TRANSMISSIONS ARE DEFECTIVE AND WHEN THEY FAIL, THEY FAIL IN A SPECTACULAR MANNER CAUSING THE VEHICLE TO VIOLENTLY JERK AND STALL, A TRAUMATIC EVENT EQUIVALENT TO JUMPING ON THE BREAKS AT HIGHWAY SPEEDS. IT IS EXTREMELY DANGEROUS AND WILL CAUSE PEOPLE TO DIE IN CRASHES. SUBARU NEEDS TO RECALL EVERY SINGLE CVT AND STOP PUTTING THEM IN NEW CARS. EXTENDING THE WARRANTY IS INSUFFICIENT.

CAR STALLED IN THE MIDDLE OF AN INTERSECTION. IT WAS TRULY FRIGHTENING BECAUSE THE BABY WAS IN THE CAR AND IT WAS DURING MORNING COMMUTE RUSH HOURS WHEN EVERYONE IS RUSHING. THE CAR IS RELATIVELY NEW WITH 35K MILES AND AM THE ONLY OWNER OF THE VEHICLE. WAS AT AN INTERSECTION AND WAITING FOR MY TURN TO MAKE A LEFT. THE CAR WAS IN 'DRIVE' AND I HAD MY FOOT ON THE BRAKE. HOWEVER, WHEN THE GREEN LEFT TURN ARROW CAME, I PRESSED THE GAS PEDAL AND THE CAR DID NOT MOVE. I MOVED FROM 'DRIVE' TO 'PARK' AND BACK TO 'DRIVE' AND PRESSED THE GAS PEDAL AGAIN AND THE CAR DID NOT MOVE. THE CHECK ENGINE LIGHT CAME ON. I MOVED FROM 'DRIVE' TO 'PARK' AND TURNED OFF THE CAR ENGINE. THEN I RESTARTED THE CAR AND MOVED FROM 'PARK' TO 'DRIVE' AND PRESSED THE GAS PEDAL AGAIN AND THE CAR DID NOT MOVE. I BEGAN PRESSING THE GAS PEDAL HEAVY TRYING TO AT LEAST MAYBE MOVE TO SAFETY AND ALL OF SUDDEN THE CAR FELT VERY SLUGGISH BUT IT MOVED. I UNDERSTAND THERE IS AN EXTENDED WARRANTY OFFERED BY SUBARU REGARDING THE TRANSMISSION, BUT WHAT HAPPENED TO ME WAS DANGEROUS TO MYSELF, MY FAMILY AND OTHERS ON THE ROAD. THIS REQUIRES FURTHER INVESTIGATION AS TO NOT PUT ANY PEOPLE'S LIFE AT UNNECESSARY RISKS.

19V910000 · Air Bags: Air Bag/restraint Control Module

Dec 19, 2019

Subaru of America, Inc. (Subaru) is recalling certain 2016-2017 Outback vehicles. A replacement air bag control module may have been installed that is not compatible with the passenger air bag module, possibly affecting air bag deployment.

Consequence & remedy

Consequence: In the event of a crash necessitating passenger frontal air bag deployment, the air bag may not deploy properly, increasing the risk of injury.

Remedy: Subaru will notify owners, and dealers will replace the passenger air bag module, free of charge. The recall began February 3, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUX-09.

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.
