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)

Had new tires installed and on the way home kept feeling wheel pulling to the right. Eyesight/lane assist feature was turned off. At one point the steering wheel dramatically jerked right and locked, completely immoveable. It jerked me into the other lane and almost into the median of the highway. I got to safety and had it towed to the dealership. I originally thought it was an issue with the tire alignment or the AWD system. They took it on a test drive and confirmed lane assist was malfunctioning in a dangerous way. They confirmed that eyesight/lane assist was turned off when this issue happened. They reset the system and said they couldn't guarantee the vehicle was safe to drive and suggested bringing it in if it happened again. I asked them to document everything they said over phone calls and voicemail. They agreed, but it took them weeks to provide a repair order. When they wrote up the repair order it included none of the information that was previously given and they said the car was, and always had been in perfect working order. I opened a case with Subaru of America and they were unable to get the information they needed from the dealership to proceed with the investigation. Upon further research, I found many similar accounts of this happening with Subarus of the same and similar year(s) and model(s). There is a class action lawsuit open for this but currently there are so many plaintiffs they cannot accept more. I refuse to drive this car as I feel that this malfunction is of life and limb consequence. I do not feel it would be ethical to sell this car without full disclosure and then would be out 30k on the car I purchased just three years ago. Reliable Subaru and Subaru of America refuse to offer a solution or help me in any way.

In the morning of Jan 28th, I drove this car off highway(North bound MoPac) to the ramp to frontage road to 360 in Austin TX. the vehicle lost control out of sudden and crashed to the left side of the road. the accident caused total loss of the vehicle but luckily a>the passages and the the driver on the car are OK. b>no other vehicle was involved . As the drive of this vehicle , I feel the crash was so strange so later on I requested both insurance company (AAA) and Subaru to investigate the possibility of malfunctions of the car. AAA -- claim number 015641968 Subaru --case 230128-1800367 AAA claimed the total lost but refused to do further investigation. Subaru took my request in March. Early this month, Subaru said their finished the comprehensive inspection and simply claimed the car was running normal when the accident happened. They don't want to share any further information about what they've found and they also don't want the inspect technician to talk to me about the results. I would like ask NHTSA, as the regulatory authority, to look into the their inspection report to make sure this vehicle does not have any abnormalities as their claimed. Thanks!

On January 24th, 2022, during a regularly scheduled maintenance services appointment at a Subaru dealership, the service technician discovered that the steering rack on my 2017 Subaru Outback needed replacement. At that time, I was advised it would be unsafe/dangerous to continue to drive my vehicle, unless I immediately replaced the steering rack. Therefore, at the guidance of the Subaru dealership, namely Freehold Subaru, I gave my consent for them to proceed with replacement of the steering components, which cost $2,223.86 (plus tax). Evidence of the cost is a copy of the detailed invoice and proof of payment is available upon request. At the time when the steering components were replaced, I was not aware of the Subaru Outback recall which involved steering components, nor did the Subaru dealership bring it to my attention, perhaps because they were also not aware of this specific recall. The recall I’m referring to is described under NHTSA Campaign Number 16V292000 (dated May 11th, 2016). As I paid for the steering rack replacement out of my own pocket, on November 29th, 2022, I contacted Subaru of America to seek reimbursement because this should’ve been covered under the steering components recall mentioned above. On December 15th, 2022, I received a message from Subaru of America stating that my particular Subaru’s VIN was not included in the recall. In my mind, this may have been an unintentional oversight on the part of the Subaru dealership by not including my Subaru’s VIN in the recall, when clearly other SAME Year Make and Model as my car (2017 Subaru Outback) were included in the recall.

Paddle shift levers--which are positioned on the steering wheel as opposed to the steering column--are too square-edged (shape), which is a design defect that can cause loss of steering control. Specifically, the sharp corner can catch on coat zippers. I was driving East, took a right turn, and intended to procced with driving South. When I attempted to straighten out the wheel, however, I was unable to do so. The paddle shifter corner "hooked" my coat zipper, along the track. This caused me to lose control of my vehicle steering, which resulted in collision with a bus stop/stand and a citation for failure to stay within my driving lane. The coat was a bit longer since it was fairly cold that morning. The zipper mechanism was made of a plastic material. The zipper was fully zipped, not half zipped and half unzipped. If the paddle shift levers were more round in shape/design, then the risk of the lever "hooking" onto clothing decreases significantly. I found examples of where other Subaru Outback drivers expressed concerns about the positioning and shape of the levers posing as a safety hazard, too.

Upon turning off my 2017 Subaru Outback Touring, the engine turned off via the push start/stop button. However, when I went to use the vehicle later the same day, the car would not start (starter would not engage). I determined that the steering wheel was NOT locked. The transmission was in Park, and I could not move the shift lever out of Park. I attempted engage the steering wheel lock by moving the steering wheel back and forth, but without success. Vehicle now totally inoperative. Vehicle is available for inspection at my residence upon request. The safety of owner and others is compromised as follows: Because of living in a semi-rural area, I rely on this vehicle to safely transport me and my family members everywhere (grocery store, doctor appointments, emergency room visits, etc.); Failure of the vehicle to operate property could expose operator and/or passengers to extremely cold weather, such as that recently experienced in December 2022. This is the second occurrence of the same malfunction. First was in July 2022. Vehicle was serviced by Subaru of Georgetown who informed me that the problem (car would not start because steering wheel lock was not engaged) was "fixed", but that they could not duplicate. No other entity, other than the dealer, has examined the vehicle. No warning lights, messages or symptoms prior to either occurrence. Driving was normal, engine shutdown appeared normal, but subsequent restarts were not possible due to the steering wheel lock not engaging (which is what the dealer informed me was the problem at the first occurrence).

System does not recognize the car is in park mode correctly. The side effect of this is ignition key gets locked in the key hole and cannot be pulled out. Repeated problem in all weather situation once the failure started to show symptom. This issue is common enough across multiple product line of Subaru vehicles with a service bulletin reference 16-112-18R with google search. Plenty of website postings and you tube videos showed different work around to resolve the issue. Dealer charges parts and labor cost to repair each vehicle request for service that could possible is a design or sensor defect issue from production quality issue. The trigger point of my vehicle having this problem could be due to recent cold weather, but this issue does not go away even after the temperature gets warmer. Trying to fix the car key situation with a young child in the back seat wanting to get out daily makes this a repeated challenge.

1EA21002 · 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.

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.
