2017 Subaru Outback

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.

The vehicle is 10 years old with 150,000 miles. The vehicle did not pass inspection, as the front end chassis/structural frame is completely rusted and corroded. The cost to replace this structure is $3,200. This seems unusual for a 10 year old car with no visible rust that is in very good condition. I read that the air conditioning condensate drips on the structure. This coupled with road salt in Rochester, NY, caused the unusual corrosion.

On Sunday, [XXX], I was driving my 2017 Subaru Outback 3.6R Touring after leaving the [XXX]. After I had merged onto [XXX] and immediately before the first roundabout under [XXX], the vehicle emitted three warning beeps, numerous dashboard warning lights illuminated, and the engine began running roughly. I was traveling approximately 31 mph when the warnings began. While attempting to reach a safe place to stop, I entered the roundabout beneath [XXX]. At approximately 7 mph, the electronic power-steering assistance stopped functioning, making the vehicle extremely difficult to steer. I was able to exit the roundabout and pull into a parking lot without a collision. I turned the vehicle off, waited approximately five minutes, and restarted it. The warning lights were no longer illuminated. Diagnostic information later reviewed by Grand Junction Subaru documented that the vehicle’s electrical voltage had dropped to 8.6 volts during the incident. The dealership could not reproduce the event or conclusively identify its cause. Although the original alternator reportedly tested normal, the dealership reprogrammed the ECU/ECM, disabled the DCM, and replaced the alternator. Because the root cause remains unconfirmed, I am concerned that the sudden low-voltage condition and loss of steering assistance could recur at highway speed. Because [XXX] and the two-lane roundabout are very busy, I felt that my life was in danger. As I continued through the roundabout, there was a Ford Platinum 3/4 ton truck next to me. If he would not have been paying attention, I feel like there would have been a collision and possibly personal injury to myself. I'm glad that this incident happened at a lower rate of speed but I am concerned that it will happen again and maybe the next time while I'm on the highway traveling at highway speeds. It could be fatal to and others. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Under Subaru's bulletin WUJ-95, certain 2015-2016 Outbacks were recalled due to the exhaust pipe front (EPF) bellows cracking. My 2017 Subaru outback has developed a crack in the bellows (flex pipe on the catalytic converter) and has had to be replaced. The emissions warranty ran out at 80K miles, I currently have 92K miles on the vehicle. If not replaced, the vehicle would not pass smog and would fail to meet emission levels certified by the EPA. Subaru's current Bulletin WUB-87 is initiating a service campaign that would involve replacement of the front exhaust pipe assembly which includes the catalytic converter. I had to pay out of pocket for the replacement part. I would like to see the catalytic converter be recalled and be able to be reimbursed for this cost. Subaru has made a defective part which cracks and breaks and needs to be re-engineered to ensure this does not keep happening. The 2017 outback has the same emission parts and placements as the 2016 and this problem will continue to happen if Subaru is not held responsible to fix the problem.

The CVT failed at 62 miles per hour on a busy interstate, XXX. This caused the drivetrain to lock. The car has been repaired and traded locally in [XXX]. The car was very difficult to steer with locked wheels in traffic. This was a rapid evasive manuver on a busy interstate. An undrivable vehicle on an interstate is life threatening to many. Flat bed driver told me I was lucky to steer off of lanes onto shoulder with four locked wheels. This incident put me in mild shock. The Subaru dealer had to replace the transmission. The dealer and Subaru Regional Rep. examined the CVT failure. It was outside of the 100,000-mile warranty by about 895 miles. Repair invoice attached. I did not have advanced warning of CVT failure. There were no warning lights on before the CVT failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Came out to car on the morning of July 1, 2026 and found windshield had cracked from the very bottom of the windshield (no impacts). This is the third windshield I will be putting in this car. Original windshield was replaced by Subaru 4/25 2025 for the same exact problem. 2015 &16 Outbacks had a settlement filed as did the 20-23 subarus. This is a known problem.These cracks limit visibility, interfere with all other safety systems: Lane change, cruise control, visibility, auto brake for emergency and other related safety systems. I could not go with aftermarket windshields (Safelite) because Subaru said they would not cover any malfunctions with the eyesight system unless it was Subaru glass. I have contacted my Subaru dealer and they said Subaru will more than likely not cover it. Their glass was put in by them 15 months ago and this not the result of a chip or impact. Came out in the morning and it was cracked. Go to any Subaru owners web sites and you will see this is a reoccurring, KNOWN problem for almost ALL Subaru models. How can safety items LIKE WINDSHIELDS ( which affects ALL other safety systems) not fall under NTHB?? So class action lawsuits cover the two PRIOR years and the next three model years, but not 2017?? jSame glass, same manufacturer, same know problem.

On Monday [XXX] were driving on [XXX] going north up [XXX]. I was doing about 60-65 mph in traffic which was flowing in both directions. While ascending the pass, the car suddenly started to misfire, rapidly lost power, power steering failed and all dash lights lit up. With no shoulder to pull out this was a very scary experience. Eventually managed to limp to a spot where I could pull out off the pavement. Car was dead. Popping the hood showed significant battery corrosion. I had a toolkit with me. The voltmeter measured the battery voltage at 9.3V. Thinking maybe cleaning the battery terminals would allow the car to be restarted, I managed to get the cables off and cleaned everything with a wire brush. But still no power. After a while a state trooper passed by and hung on while I contacted a towing service. After another 1.5 hours, the tow truck arrived and towed the car the 60 miles or so to the dealership in Denver with my wife and I in the cab of the tow truck. Dealer repair invoice indicated Data Control Module (DCM) "causing excessive draw on electrical system." More significantly, the battery had drained below the the operating threshold voltage required for vehicle drivability (understood to be 10-10.5V). There was no mention of this by the dealer service adviser. Although dealer diagnostic was carried out, no computer codes were provided. Vehicle mileage at time of incident 73,456. I have owned the car since new and have all service records. Car was repaired and picked up from dealership on 06/10/26 with a replacement DCM. Battery was charged up but not replaced and left in corroded state. Battery will probably have been weakened by such a total discharge with reduced life expectancy. I have uploaded the dealer repair invoice. I have reported this incident to Subaru of America. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
