TWO SEVERE WINDSHIELD CRACKING INCIDENTS WITHIN 18 MONTHS. VEHICLE WAS IN MOTION BOTH TIMES ON A STRAIGHT SURFACE IN GOOD WEATHER AND MAY HAVE BEEN STRUCK BY A SMALL STONE BUT I DIDN'T SEE ANYTHING. I NOTICED A BARELY VISIBLE DING THAT TURNED INTO A SPREADING CRACK WITHIN A FEW DAYS AND MADE REPLACEMENT OF WINDSHIELD MANDATORY. 18 MONTHS LATER, THE SAME THING. A TINY IMPACT ON THE GLASS SHATTERING THE WINDSHIELD. THE GLASS SEEMS VERY THIN AND FRAGILE. BECAUSE OF EYESIGHT DRIVER ASSIST TECHNOLOGY, I CANNOT HAVE IT REPAIRED AT ANY OTHER PROVIDER BUT THE DEALER.

THE KEY GETS STUCK IN THE IGNITION OF MY 2017 SUBARU LEGACY. I START THE CAR AGAIN, I TWIST THE STEERING WHEEL LEFT AND RIGHT, AND THE KEY STILL DOES NOT COME OUT. MY CAR WAS PARKED EVERY TIME THIS OCCURRED. SO I GOOGLED THE ISSUE AND THERE WERE A TON OF VIDEOS AND FORUMS DISCUSSING THIS EXACT ISSUE! APPARENTLY THIS IS A KNOWN ISSUE AT SUBARU. BECAUSE OF ALL THE COMPLAINTS, SUBARU FIXED THE ISSUE STARTING WITH THEIR 2018 MODELS. SUBARU RELEASED A SERVICE BULLETIN DATED 3/15/18 WITH THE SUBJECT LINE: "IGNITION KEY STICKING / DESIGN CHANGE TO CVT SHIFTER / SELECTOR LEVER COMPONENTS". THAT IS MY EXACT PROBLEM! I PURCHASED THE LEGACY USED IN 2020 AND IT IS NO LONGER UNDER WARRANTY. THE DEALERSHIP GAVE US A QUOTE OF $512.92 TO FIX THE "SHIFTER ASSEMBLY". WE ARE DISGUSTED THAT SUBARU WILL NOT COVER THIS COST, AS IT IS A KNOWN ISSUE. I'VE OWNED MANY CARS IN MY LIFE AND I HAVE NEVER HEARD OF A KEY GETTING STUCK IN A 3 YEAR OLD CAR! THIS IS AN ISSUE WITH THE MANUFACTURING, YET THEY DID NOT ISSUE A RECALL. IT LOOKS LIKE WE ARE GOING TO NEED A NEW "SELECT LEVER ASSEMBLY" AND SUBARU IS TOO CHEAP TO PAY FOR THIS FIX.... AN ISSUE I DID NOT CAUSE!

16V716000 · Air Bags:knee Bolster; Steering:column

Oct 6, 2016

Subaru of America, Inc. (Subaru) is recalling certain model year 2017 Legacy and Outback vehicles manufactured September 21, 2016, to September 23, 2016. In the affected vehicles, the knee guard bracket may not be properly attached to the steering beam assembly.

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.

Subaru of America, Inc. (Subaru) is recalling certain model year 2016-2017 Legacy and Outback vehicles manufactured February 29, 2016, to May 6, 2016. The steering column on the affected vehicles may have been improperly machined, and as a result, turning the steering wheel may have no effect on the direction of the wheels.

Consequence & remedy

Consequence: The loss of steering ability would increase the risk of a crash.

Remedy: Subaru will notify owners, and dealers will inspect the lot number on the steering column, replacing the steering column, as necessary, free of charge. The recall began May 13, 2016. Owners may contact Subaru customer service at 1-800-782-2783 or by visiting http://www.wtd65.service-campaign.com. Subaru's number for this recall is WTD-65. Note: Until the vehicles have been inspected, owners are advised not to drive their vehicles.

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.
