INVOLVED IN ACCIDENT TO RH DOOR AND FENDE. CURTAIN AIR BAG DEPLOYED, SEAT BELT TRIGGERED, NO OTHER AIRBAG SYSTEM ISSUES. AFTER REPAIR INCLUDING CURTAIN AIR BAG REPLACEMENT AND MODULE RESET AS WELL AS ALL SENSORS REPLACED, AIR BAG LIGHT STILL ON. ISSUE TRACED TO RH SEAT BACK AIR BAG. APPARENTLY WHILE IT WAS TRIGGERED BUT IT DID NOT DEPLOY. QUESTION IS THIS AN ISSUE THAT SHOULD BE TAKEN UP WITH THE MANUFACTURER SINCE THE AIR BAG WAS TRIGGERED BUT DID NOT DEPLOY BUT NEVER THE LESS IT NEEDS TO BE REPLACED. CANNOT TELL IF VEHICLE WAS IN MOTION AS IT WAS PURCHASED AT AN AUCTION.

I TOOK MY 2016 SUBARU FORESTER IN FOR SERVICE AND MENTIONED A STICKY IGNITION. I WAS TOLD THE SHIFTER PLATE ASSEMBLY NEEDED TO BE REPLACED AT A REPAIR OF $600.00. THE CAR HAS 45,000 MILES. I QUESTIONED THE SERVICE DEPARTMENT ABOUT HOW OFTEN THIS HAPPENS WITH IT BEING A RELATIVELY LOW MILES CAR AND HE STATED THAT HE IS REPAIRING 3 OTHERS IN THE DEALERSHIP JUST TODAY. I ALSO READ THAT SUBARU REPLACED THE ASSEMBLY DUE TO PROBLEMS WITH THEIR LAST ITERATION. I AM CONCERNED THERE IS ANOTHER ISSUE WITH THIS ASSEMBLY AND IT NEEDS TO BE RECALLED.

MY 2016 SUBARU FORESTER HAS TWICE EXPERIENCED A SUDDEN ENGINE STALL WHILE CRUISING AT APPROX. 70 MPH WHEN THE FUEL WAS LOW. IN BOTH CASES THE LOW FUEL WARNING LIGHT WAS NOT ON AND THE VEHICLE SHOWED FUEL IN THE TANK WITH FUEL RANGE OF 70-100 MILES. IN BOTH CASES ONCE THE CAR WAS STOPPED IT STARTED AGAIN AND RAN NORMALLY UNTIL AND AFTER REFUELING. THIS HAS HAPPENED ONLY AT HIGH SPEED WHICH MAKES THE CONDITION ESPECIALLY DANGEROUS IN TRAFFIC. AFTER THE FIRST INCIDENT (@ 42,000 MI.) I TOOK THE VEHICLE TO A SUBARU DEALER WHO CHECKED THE VEHICLE AND FOUND NO EXPLANATION. OF COURSE THE DEALER WAS NOT ABLE TO DUPLICATE THE EXACT CIRCUMSTANCE OF THE POWER FAILURE. THE VEHICLE IS CURRENTLY UNDER EXAMINATION FROM THE SECOND INCIDENT WHICH OCCURRED YESTERDAY (@ 50,000 MI.). I DO NOT KNOW IF THIS IS A FUEL PUMP PROBLEM BUT I HAVE SEEN OTHER POSTS THAT SUGGEST THAT MAY BE THE CAUSE.

THE POLE WAS DESIGNATED FOR A HANDICAPPED SPACE .AND CAR . LUCKILY THERE WERE NO PEDESTRIANS THERE OR I COULD HAVE HURT OR KILLED THEM. NO DAMAGE TO CAR . I DIDN'T KNOW WHAT HAPPEN. I CHECKED MATS TO MAKE SURE THEY WERE NOT UNDER GAS BECAUSE I'VE HEARD THAT COULD HAPPEN BUT NO ALL WAS GOOD . GOING FORWARD JUST KEPT WATCH AND SEE IF IT HAPPENS AGAIN CAUSE THEN I WOULD KNOW THERE IS A PROBLEM WITH THE CAR. ONE, TWO, THREE TIMES, NO DEFINITELY SOMETHING WRONG WITH CAR. THE MOST RECENT SEPT. 8, 2020, I WAS ON SIDE STREET STOPPED AT LIGHT. TOOK FOOT OFF BRAKE TO INCH UP TO MAKE TURN ALL OF SUDDEN CAR LUNGED FORWARD TO INTERSECTION I QUICKLY MADE TURN. LUCKILY AVOIDING ACCIDENT. WHEN I TOOK CAR IN TO BE CHECKED WAS TOLD BY REPRESENTATIVE AT THE DEALERSHIP SHE NEVER HEARD OF SUCH A THING. WHEN THIS HAPPENS IT'S USUALLY DUE TO HUMAN ERROR AND THEY'RE NOT AWARE OF ANY ACCELERATION ISSUES WITH THEIR CARS. SHE THEN PRECEDED TO ASK IF I HAD AIR CONDITIONER ON WHEN THIS HAPPENED. I SAID I DON'T REMEMBER BUT I'M ASSUMING I DID. LEFT CAR TO BE CHECKED.R DEALERSHIP SAID THE MECHANIC DROVE CAR FOR 3 MILE , COULD NOT DUPLICATE MY COMPLAINT.
KEY DOES NOT RELEASE FROM THE IGNITION WHEN CAR IS STOPPED, TRANSMISSION IS IN PARK AND FOOT BRAKE IS APPLIED.

1PE19009 · 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.
