While driving my vehicle on my daily trip to work, I experience sudden power loss. My interior lights began to blink erratically, as my vehicle loss power and caused me to panic, as I was entering the highway. Some highways have no shoulders, so as quickly as I entered the highway, I pulled off took the next exit. I went into a shopping center, to see what the issue was. I noticed that my radio and my air conditioning loss illumination. I turned the car off, opened the hood. I did not see anything of significance, I started the car up again, now the radio would not even start nor did the air conditioning. I phoned the Subaru dealer, to be told that this happens often! What, I thought to myself? I asked them if this was a well-known problem, why this has not become part of a recall, or why the dealership not contact Subaru of America, to work with their customer base and remedy the issue. I was told, that all that is done in the "diagnostic process", any codes are cleared, and this should get you back on the road. Are you kidding me, this is truly any motorist's nightmare. Losing power on a major highway, any road at night, or on a turn will literally bring catastrophic consequences to us Subaru owners, but all other motorists as well.

My 2016 Subaru Forester is having acceleration and possibly fuel propulsion issues. It stays in low gear, high RPM when accelerating. This happened after a Yellowstone week long road trip from San Leandro, CA. The MPG has dropped from 24mpg to 12mpg and has been at Hayward Subaru since 8/15/2023. They have not provided a known issue. Still trying to figure out what is wrong. There was a low oil warning light on the way home and we stopped for an oil change in West Sacramento within 15 miles of the light coming on. The issue has been happening since the oil change. Only oil change and air filter replacement done on 8/8/2023. Thought maybe its a fuel injector issue. Still at dealership. We did fill the fuel tank with 85 octane in Elko, NV once.

parked in angle space and turned off car. went into store for about 15 minutes. got in car and started it. heard a noise sounding like a car revving engine and looked behind me to see if it was another vehicle. realized it was my car. tried to push foot on accelerator but it was all the way to floor and would not come up. immediately put foot on brake and turned off car. looked at floor mat and found that was not the issue. waited about 30 seconds and turned car back on and found that the accelerator was not all the way to the floor like before. It ran like it always has. drove 10 minutes back home with no issue. when home, went in house for 15 minutes; came back out and started it and ran like normal. i then searched the issue and discovered SEVERAL complaints about this issue. Thankful that I didn't run into a building as anyone else (there was a man walking into a house DIRECTLY in front of where I was parked.....I would have hit him if i had put the car in drive.) No warning lights or anything else visible on car. no issue prior. not been inspected by anyone else or the dealer at this time. Not reported to police department or insurance company. I am NOT an elderly person and I KNOW I did not accidentally do anything wrong when this issue occurred. purchased this subaru in 2018 as they are highly rated as far as safety goes and very dependable. I am extremely disappointed that there has NOT been a recall on this issue. Do people have to die before subaru will issue recall?!?! I was planning to trade in for a newer Subaru but am definitely hesitant to do so at this time. I drive with my young grandchildren in vehicle and am even hesitant to do that in the future. PLEASE, Subaru, issue a recall for this issue.

Since 2018 we starting noticing random power loss and every time we took vehicle to dealership for maintenance, they could never find an issue. The loss of power began at random as well went up hills. It felt as if there was something blocking the engine from preforming as intended. Maybe poor air flow or turbo lag. We would let go of accelerator because it felt as if the car was going to stall. This power lag or loss would last 5-10 minutes. Then more issues appeared during 2018-2022. The issues were always at random. Issues we witnessed were: loss of power (poor air flow/ bad compression), car seemed to want to stall at stops, weird metal clacking (which we were able to record), bopping car at stops (as a manual car would before stalling). A code was never available for dealership to know the problem at hand. Over the past years we continued to take in the vehicle for the issues we experienced. The dealership never found the root of the problem. The problem continued until 2022 and now the car is inoperable. 400 miles out of warranty and Subaru does not want to fix this issue that had been happening since 2018. I have been waiting for Subaru of America to contact me since 7/22/22. I could never get an answer from case worker. Subaru wants us to pay out of pocket roughly 4500 and then maybe they cover the rest.

Our Subaru Forester is slow to respond on acceleration and then surges quickly. This problem just started to surface. Our concern is when stepping down on the accelerator the car is very slow to react and then surges forward quickly, creating a serious concern over a potential accident. On August 17, 2022 I was reversing up my driveway to the garage and as I depressed the accelerator the car failed to respond. I was reluctant to depress the pedal further over concern it might suddenly surge backward too fast. What was concerning is that the accelerator did not respond as normal. August 18th, I started the car, drove out of the garage and onto the street. When I stepped onto the accelerator the car showed no response, then suddenly without warning surged forward at high speed, catching me off guard. I stepped on the brake and the car immediately stopped. I carefully tried to drive forward, again the car surged forward. I drove back into the garage. Our neighbor’s nephew took it for a drive and experience the same unexpected surge of acceleration. It was towed to the Subaru Dealership. The Dealership has consistently maintained our Forester since purchased. I asked if the car had surged and the Service Advisor shared that the technician had noticed an irregularity in acceleration. However, Diagnostic tests found nothing. The shop manager said he put almost 40 miles on it but found nothing. The service adviser called and suggested we come in and ride with the shop manager, which we did. He test drove it for a few miles and the acceleration appeared normal. He did say after the test drive that he sensed something irregular about the acceleration when leaving a stop sign. We asked they keep the car and test the car after sitting over the weekend. I asked service advisor and the shop manager if he had ever heard of a Subaru with this issue of being slow to respond on acceleration and then surging quickly. They both said they had never heard of this issue

PE19009 · Occupant Detection System (ods) Failure

Opened Aug 6, 2019 · Closed Jan 22, 2020

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Air Bags:frontal:passenger Side:inflator Module; Air Bags:sensor:occupant Classification

The Office of Defects Investigation (ODI) opened PE19-009 to investigate 51 complaints and additional Early Warning Report (EWR) data related to allegations of front passenger seat Occupant Detection System (ODS) malfunctions in model year (MY) 2016 through 2018 Subaru Forester vehicles. These vehicles use a capacitive type ODS, which is intended to classify the occupant of the passenger seat as either full-sized, small stature, a child seat or other object. The complaints reported the ODS failed to operate properly, the SRS (Supplemental Restraint System) warning light illuminated, and/or the ODS incorrectly suppressed (turned off) the front passenger air bag when the seat was occupied by a full-sized passenger. In a frontal crash that is sufficient to warrant deployment, a suppressed air bag may increase the risk of injury to the occupant of the seat.On August 14, 2019 ODI sent an Information Request (IR) to Subaru requesting information on the subject vehicles and MY 2014-2015 Subaru Forester vehicles.On October 3, 2019, Subaru submitted a Defect Information Report (DIR) to NHTSA describing a safety defect in the passenger-side front airbag Occupant Detection System (ODS) harness of 366,282 MY 2015-2018 Subaru Forester vehicles equipped with seat heaters.The DIR stated that over time, due to a decrease in contact pressure between the terminals in the ODS sensor mat harness, a temporarily unstable electrical connection may be possible. If the connection is temporarily unstable, the ODS may not properly determine the status of the right front seat occupant. If the ODS is unable to correctly determine the status of the front occupant, the airbag warning light may illuminate, and the front passenger airbag may deactivate even though the seat is occupied, increasing the risk of injury to the front passenger in the event of a crash.Using vehicle production data and field occurrence frequency, Subaru determined the potentially affected vehicle production range to be between January 20, 2015 ?and August 1, 2017.In addition, Subaru indicated that over 99 percent of the related MY 2015-2018 field reports with vehicles in the production range involved vehicles with seat heaters.NHTSA's analysis of complaint and warranty claim data showed 1,440 of the complaints and 11,672 of the claims involve vehicles with seat heaters that were built within the production range covered by Subaru's recall.In addition, NHTSA's analysis showed a complaint rate of 393.1 per hundred thousand vehicles for the recalled population and 89.0 for MY 2014 through 2018 vehicles that are not included in the recall. Analysis of warranty claim data found a claim rate of 3.2 percent for the recalled population and 0.3 percent for MY 2014 through 2018 vehicles that are not included in the recall.Subaru will instruct owners with Subaru Forester vehicles produced in the affected vehicle production range, to bring their vehicles to a dealer to have the sensor mat harness, inspected and replaced with a new part, including the seat cushion assembly, if necessary.Based on ODI's analysis, the actions taken by Subaru mitigate any unreasonable risk to safety posed by ODS sensor mat failures in the subject vehicles. For subject and peer vehicles outside the recall population and those equipped without seat heaters, ODI's analysis indicates that there is currently no safety-related defect trend. Given these circumstances, further use of the agency resources in this matter does not appear to be warranted. Accordingly, this investigation is closed.
