While in a parking lot moving at very slow rate speed the car suddenly accelerated on its own. I had just slowly turned within a parking lot in preparation to backing into a parking space. I had just removed my foot from the accelerator and the car was almost at a stop and I was about to brake and put the car into reverse when it suddenly and rapidly accelerated on its own. My foot was not touching the accelerator at the time (it was over, but not yet touching, the brake). The car felt as if someone had suddenly slammed on the accelerator, but my foot was not on the accelerator at the time. Luckily my foot was over the brake when the rapid unexpected acceleration occurred and also luckily there were no cars in front of me. I was able to immediately slam on the brake so that the car did not hit anything. Before I was able to brake, the car quickly lurched forward at a surprisingly rapid rate of speed for a short distance. Quick application of the brakes stopped the sudden and rapid forward movement of the car. I did not notice any warning lights or messages on the car. This could have been a very dangerous situation. If someone had been walking in front of the car, they would have been hit and potentially seriously injured. If there had been cars parked in front of the space I was about to back into, the car would have hit them and caused damage. This happened earlier today and I have not yet reported it to the dealer. No police or insurance personnel were involved as I managed to avoid an accident. The event occurred today, Wednesday December 3rd at about 11 am. There were no other witnesses. To my knowledge this is the first occurrence of this rapid unexpected acceleration for this car.

I experienced sudden acceleration in downtown and almost hit three cars, caused me to run three red lights and almost hit pedestrians. I had the car, 2017 outback Subaru towed to the dealer and was told there are no recalls, but saw many problems listed on the NHTSA website. It was terrifying and still shakes me up when I think what could have happened. Subaru told me this was the first they have seen this and that I do not have the extended warranty and I would be held for the cost. I am beyond upset. They tried to have me pick up the car after finding nothing. I told them they are to keep it until they find the issue. I have a loaner from them.

I was driving my 2017 Subaru Outback on a trip from New York to Florida. On I-95 in heavy traffic I hit a bump in the road, and at that instant, nearly every warning light on my dash came on, including EyeSight, lane departure, and emergency braking. My adaptive cruise immediately disengaged causing the vehicle to suddenly slow (this incident was at highway speed). The "brake" light was also illuminated. Not knowing what happened, I pulled over on the side of the highway and found that the wire to the electric parking brake on the passenger side had disconnected from the brake module. I tried to plug it back in, but it would not stay. I secured the cable with a hair tie and continued on the trip. Approximately 500 miles later, I hit another bump or pothole, and the same thing happened. I checked under the car again, and discovered that the driver side had failed in the same manner. I secured the cable with another hair tie and was able to complete my trip. When I returned home, I discovered that this is a known issue and there is a Subaru TSB published, 06-63-18R. There is no warranty on this issue, and I was charged nearly $750 to fix a KNOWN PROBLEM caused by a plastic retainer. In my opinion, this issue should be treated as a safety defect and subject to a recall to replace with the newer part. Having all of your vehicle assists suddenly fail at highway speed in heavy traffic is a disconcerting and dangerous event.

Yesterday, I was accelerating at a reasonable rate from a stop. My Outback stopped responding to the accelerator pedal and kicked up to 3500-4000 rpm. My brakes could barely hold the vehicle back and it forced me to slip my transmission in and out of neutral to prevent a crash. I pulled over twice to restart the car, hoping to reset something and address the issue, but it was still present when I pulled into my driveway and stopped the car for the evening. This morning, I started the vehicle and to my surprise, it started normally. I took it to my local mechanic who checked for codes or lights ( and carpets on the accelerator, etc,) and there were none. He also went under the hood and checked air filters and the entire intake system and found nothing. This is the third time I have experienced this issue. The first time I was making a right hand turn into a parking lot. I restarted the car and the issue went away. The second time it lasted a little longer but also was resolved by restarting the car. This third time, I was also making a right turn, but this time from a parking lot to the road, where I continued to drive. Two attempts at restarting did not resolve and it remained in this out-of-control condition until I turned it off.

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.
