Throttle fails to respond for a brief but serious amount of time. When pulling into traffic, instead of accelerating the engine remains at an idle and the car moves forward slowly. I push on the throttle trying to make it go. Then it takes hold and the car leaps forward. Safety: Normal power is delayed as the car moves into traffic. Oncoming traffic must slow to prevent an accident. The dealer where I purchased the car, Santa Monica, CA, tried to find error codes. Also removed the throttle valve to check that it wasn't somehow stuck. They drove the car briefly. They say they've done all they can. No warning lamps, messages, codes stored in the computer. Note that the throttle pedal signals the computer to work the engine throttle valve (so I'm told). Problem occurs about once a month. First time was when I took posession at the dealer's. I requested to recind my purchase but, because I didn't by the cancellation option ($250), they refused.

I was pulling into a space in a parking deck, foot on brake. Just as I was shifting into Park, the car lunged forward and slammed into the guard rail. Popped the fender and did some paint damage. Thankfully no one was hurt, but frightening to think that this could have happened in an intersection.

On December 1, 2022, as I jockeyed my car out of my garage it accelerated as I tried to break and I slowly drove into a stack of boxes at the back of the garage. No damage and I was able to back out and continue my journey. My wife was in the car with me. I continued on my trip to North Carolina without incident. On Dec 5, 2022, on our return home I exited the highway in southern Pa. to get supper. After I entered the off ramp and then prepared to obey a yield sign, the car again accelerated despite my attempt to brake. I swerved to the right to avoid any traffic and the car did eventually stop. Again no damage. Subsequently we resumed our travel and arrived home with no further incident. On December 6, 2022, as I backed out of the garage again it accelerated as I tempted to brake. Fortunately no damage and the car did finally stop in the driveway. I called the dealer and drove the car in for a checkup. They found no problems and reported the car ran as designed. While in the service department they replaced the muffler, put in new spark plugs and replaced a wheel bearing. I have had no further problems since I picked up the car on December 12, 2022. The dealership was very cooperative but I wanted to issue this concern with your agency in case there have been other complaints of this nature. I drive my car with some anxiety that another incident may recur. Thank you for your review and anticipated response.

I was pulling into a parking lot. The attendant told me to back our 2017 Outback into a spot running along a fence and row of trees. I pulled forward, put my foot on the brake to fully stop. I then moved from "drive" to "reverse". Immediately, the engine started to rev very loudly as if my foot was on the accelerator (it was not!). The accelerator seemingly went to the floor and within a few seconds our car was in reverse at high speed. The only thing that stopped us was a maple tree and fence that we hit - about 15-20 yards behind us. The backend of the car is pushed in, including into the cabin, the rear window shattered etc. The fence is destroyed and tree damaged. My spouse, in the passenger seat, experienced a minor concussion and we both ended up with severe whiplash. If it weren't for the tree we would have just kept going. We are waiting on State Farm claim adjustor to see the car. I did inform Subaru (where the car was towed) what happened; they didn't seem particularly interested. We did get a police report. Thankfully, no one was hit. There were no signs of any problem with the accelerator prior to this incident. I am now, however, aware of numerous complaints and suits in related cases.

On 2/13/22 I started my vehicle to move it back into the garage. Upon putting it into 'Drive' the engine unexpectedly started to ramp up the RPMs accelerating the vehicle forward. Fortunately I had my foot on the break slowing the progression and I was able to switch the gear to 'Neutral'. At that point the engine began to continue to ramp up the RPMs. I tried depressing and releasing the accelerator to see if the engine would respond and decrease the RPMS, it did not. I then switched off the engine to keep it from accelerating/increasing the RPMs. About five minutes after the initial incident I started the vehicle. Immediately upon startup the vehicle RPMs starting to ramp up. I tired depressing and releasing the accelerator to see if the engine would respond and decrease the RPMS, it did not. I then switched off the engine to keep it from accelerating/increasing the RPMs. After another five minutes I started the vehicle again. This time I let the car warmup for a minute before placing it into gear. During this time I did not experience another incident.

THIS IS CLEARLY A DANGEROUS PROBLEM, AND IT SEEMS SEVERAL OTHER 2017 OUTBACK OWNERS HAVE REPORTED SIMILAR ISSUES. IT APPEARS TO BE SIMILAR TO THE 2018 FUEL GAUGE RECALL (WTW-82) BUT FOR 2017 VEHICLES. UNFORTUNATELY, I DIDN'T THINK TO TAKE A PICTURE OF THE FUEL GAUGE, BUT WAS ACTUALLY PAYING CLOSE ATTENTION AS I HAD RECEIVED THE NOTIFICATION FOR SUBARU'S WUD-89 "DISTANCE-TO-EMPTY SOFTWARE UPDATE," SO I KNEW THE DISTANCE-TO-EMPTY INDICATOR WAS WRONG, BUT GIVEN THE NOTICE SAID NOTHING ABOUT THE FUEL GAUGE ITSELF AND ONLY MENTIONED THE DTE SOFTWARE WAS INCORRECT, I MADE THE NATURAL ASSUMPTION THAT THE GAUGE ITSELF WAS STILL AT LEAST REMOTELY ACCURATE.

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.
