2015 Subaru Legacy

The defect

Subaru of America, Inc. (Subaru) is recalling certain model year 2015 Legacy and Outback vehicles manufactured on July 20, 2015. The brake fluid used in these vehicles may contain excess moisture which may adversely affect the performance of the electronic stability control system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control Systems."

The risk

Poor performance of the electronic stability control system when it is activated may result in a loss of vehicle control, increasing the risk of a crash.

The remedy

Subaru will notify owners, and dealers will perform an ABS activation, then flush and replace the brake fluid, free of charge. The recall began on May 20, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTC-64.

The risk

If the transmission oil leaks onto the exhaust pipe, there is a possible risk of fire.

The remedy

Subaru will notify owners, and dealers will replace the propeller shaft, free of charge. The recall began on August 28, 2015. Owners may contact 1-800-782-2783. Subaru's number for this recall is WQU-56.

The defect

Subaru of America, Inc. (Subaru) is recalling certain model year 2015 Legacy vehicles manufactured March 10, 2014, to April 16, 2015, Outback vehicles manufactured February 24, 2014, to April 16, 2015, Impreza vehicles manufactured September 9, 2014, to April 14, 2015, XV Crosstrek vehicles manufactured October 16, 2014, to April 15, 2015, and 2016 WRX vehicles manufactured March 23, 2015, and equipped with the Eyesight Driver Assist System. If the switch that activates the brake lights fails, the automatic pre-collision braking component of the driver assist system will not function.

The risk

If the automatic pre-collision braking system does not function as intended, the vehicle will not react to an obstacle in its path, increasing the risk of a crash.

The remedy

Subaru will notify owners, and dealers will reprogram the driver assist system, free of charge. The recall began on July 20, 2015. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WQS-54.

the air bags

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.

2015 Subaru Legacy 2.5i, approximately 48,000 miles. CVT transmission failed suddenly with no prior warning signs. Vehicle was exclusively dealer-serviced for its entire life. While driving, the transmission began shuddering, slipping, and making metallic grinding noises. Vehicle could barely climb a small ramp and was locked in limp mode, making it unsafe to operate in traffic. Diagnostic codes P0841, P0700, and C1431 were stored. Authorized Subaru dealer confirmed the failure. Technician stated the valve body likely failed first — a known defect per Subaru TSB 16-107-17R — which then caused the CVT chain to slip. Dealer quoted $11,000 for a remanufactured CVT replacement. Service …

Incident ~ 5:40 pm, Geneva NY Weather ~ 10 F, not snowing. Background. On or shortly after being started, the vehicle had exhibited prior incidents of extremely rapid engine acceleration not initiated by the operator. Most recently the day before. The incident: I was in the process of very slowly parking the vehicle in a narrow laneway, and positioning the vehicle behind and in line of one other, both parallel to the laneway, in a small area that had been cleared of snow, leaving the laneway open. First, I stopped the vehicle opposite of the parked vehicle's driver side door. Second, I reversed and backed up and positioned the vehicle behind that vehicle. This involved firmly stepping on …

towed · 175,000 miles

The contact owned a 2015 Subaru Legacy. The contact stated that while the vehicle was parked, the contact opened and closed the trunk, triggering the alarm system. The alarm system failed to deactivate immediately. The vehicle then failed to restart as needed, and the "Shift to Park" message was displayed while the transmission was in park(P). The vehicle was towed to the dealer, where the brake fuse was replaced; however, the failure persisted. The contact replaced the brake fuse for a second time, but the failure recurred. The vehicle was towed back to the dealer, where an unknown repair was performed. The contact later sold the vehicle. The manufacturer was not made aware of the failure. …

2015 Subaru Legacy 2.5 engine. Fuel gauge is inaccurate. My daughter was on the highway when it ran out of fuel. Had car towed to a independent shop. They said that the fuel gauges is a problem for Subaru 's and that they had seen it before on other Subaru's.
