BATTERY ISSUES ARE NON STOP! BATTERY DIES ALL THE TIME. WE HAD A NEW 2016 OUTBACK PREVIOUSLY, THAT HAD TO BE TOWED BECAUSE IT WOULD JUST DIE. WE TRADED IT IN FOR A NEW 2017 OUTBACK AND IT'S EVEN WORSE. BATTERY HAS BEEN REPLACED (NOT SURE HOW MANY TIMES), AND ISSUE IS STILL THE SAME. LEAVES US STUCK/STRANDED IN RANDOM PLACES, AND BACK HATCH WILL SOMETIMES BEEP NON STOP EVEN THOUGH IT'S COMPLETELY CLOSED. WE HAVE TO KEEP AN EMERGENCY JUMP KIT WITH US CONSTANTLY. THE BACK HATCH WON'T OPEN WHEN BATTERY IS DEAD/LOW, WHICH IS CRAZY THAT THERE ISN'T SOME TYPE OF OVERRIDE TO THIS. I HAVE SEEN COUNTLESS BATTERY ISSUES FOR THIS VEHICLE AND I'M BEYOND SHOCKED THAT THIS HASN'T BEEN FIXED/ADDRESSED BY SUBARU. WE ARE FED UP WITH THE BATTERY DRAIN, AND DO EVERYTHING WE CAN SO WE CAN (HOPEFULLY) PROACTIVELY START OUR VEHICLE (HAVE ALL INTERIOR LIGHTS OFF, RADIO OFF, AIR OFF - ALL SYSTEMS POSSIBLE TURNED OFF). EVEN THAT DOESN'T ALWAYS WORK. WE SPEND EXTRA MONEY ON GAS JUST TO RECHARGE THE CAR BY DRIVING IT MORE MILES THAN WE WANT TO. I'M GONNA BE DONE WITH SUBARU AFTER THIS.

I HAVE TO TURN MY KEY INTO THE ON POSITION, SHIFT THE GEAR INTO EITHER 'N' OR 'D', THEN BACK INTO THE 'P' POSITION SEVERAL TIMES BEFORE I CAN GET MY KEY OUT. THIS IS SUCH A SAFETY HAZARD. THIS HAPPENS WHEN MY CAR IS STATIONARY AND PARKED, AND I AM ATTEMPTING TO LEAVE MY VEHICLE. APPARENTLY, MANY PEOPLE ARE HAVING THIS SAME ISSUE AND SUBARU DOESN'T CARE ENOUGH ABOUT THEIR CLIENTS TO REPAIR THIS PROBLEM. THEY ONLY CARE ABOUT THEIR $$$.

MUTIPLE TIMES WHEN THE CAR IS STOPPED AND PUT INTO PARK,REGARDLESS OF WHERE, THE KEY WILL NOT COME OUT OF THE IGNITION. THE SWITCH CAN BE TURNED OFF, BUT THE KEY WILL NOT COME OUT OF THE IGNITION. THE GEAR SHIFT HAS TO BE MANIPULATED MULTIPLE TIMES BETWEEN DRIVE AND PARK IN ORDER TO EVER REMOVE THE KEY. THIS MAKES IT QUITE DIFFICULT TO RUN ERRANDS OR TO TAKE A TRIP, NOT KNOWING IF THE ABILITY TO REMOVE THE KEY WILL BE POSSIBLE. AND, OF COURSE, IF THE KEY HAS TO BE LEFT IN, THE POSSIBILITY OF THEFT WOULD BE GREAT. CAR IS NOT RECOGNIZING THE GEAR SHIFT IS IN PARK. ON ONE OCCASION, I HAD TO LEAVE THE KEY IN THE CAR IN MY DRIVEWAY, BUT THIS RUNS THE BATTERY DOWN. DEALER WHERE I AM TAKING CAR TO BE REPAIRED AS WELL AS THE SUBARU OF AMERICA CONTACT, ADVISED ME THIS IS A REGULAR OCCURRENCE AND SUBARU IS WELL AWARE OF WHAT IS HAPPENING. I FEEL THIS SHOULD BE PUT ON THE RECALL STATUS! THIS HAS HAPPENED ON MULTIPLE OCCASIONS SINCE BUYING THE CAR ON JUNE 5, 2020. TODAY'S DATE IS 08/14/20. REPAIR WILL BE MADE MONDAY, 08/17/20.

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.

Consequence & remedy

Consequence: If the knee guard is not properly attached and the driver is not wearing a seatbelt, the knee guard may not be able to properly restrain the driver's lower body in the event of a crash, increasing the risk of injury.

Remedy: Subaru will notify owners, and dealers will inspect the knee guard welding on each vehicle's steering beam, replacing the beam as necessary, free of charge. The recall began November 14, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTL-72.

Aug 3, 2016

Subaru of America, Inc. (Subaru) is recalling certain model year 2017 Outback vehicles manufactured June 20, 2016, to June 23, 2016. The affected vehicles may have improperly tightened attaching bolts for the front left and right brake calipers, wheel hubs, and the right stabilizer clamp.

Consequence & remedy

Consequence: If any of the front brake caliper, wheel hub or stabilizer clamp attaching bolts loosen or detach, the related components would also become loose and may detach possibly making the vehicle unstable and reducing the braking capability. These conditions would increase the risk of a crash.

Remedy: Subaru has notified owners, and dealers will inspect the bolts for proper torque, and replace any loose bolts, free of charge. The recall began on August 8, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTE-66.

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.
