WHEN ON AN INCLINE, AND OR ENTERING A HIGHWAY WHILE ACCELERATING THE CAR WILL GO INTO THE HILL DECENT MODE. EVERY LIGHT ON THE DASH WILL LIGHT UP! I AM FORCED TO PULL OVER BECAUSE THE ENGINE IS NOW SCREAMING!!! I THEN NEED TO TURN THE CAR OFF AND ON TWO TIMES IN ORDER TO BE ABLE TO DRIVE IT. NOW HALF THE LIGHTS ARE STILL ON. BUT THE CAR IS RUNNING NORMALLY. IT WILL TAKE TO MORE TIMES TURNING OFF THE ENGINE BEFORE ALL THE LIGHTS GO OFF. THE DEALER CLAIMED I WAS DRIVING TWO FOOTED. LEFT FOOT ON BRAKE AND RIGHT ON GAS. NOT TRUE I DO NOT DRIVE LIKE THAT. YOU CAN VERIFY THIS BEHAVIOR WITH STARLINK WHICH I HAD THE FIRST YEAR. STAMFORD SUBARU HAS HAD THE CAR A WEEK NOW AND I HAVE HEARD NOTHING! THE SECOND ISSUE IS THE FRONT END. WHEN GOING OVER A BUMP OR TURNING INTO A DRIVEWAY THERE IS A LOUD CLUNK. TO ME IT SOUNDS LIKE BALL JOINTS. STAMFORD SUBARU HAS TOLD ME IT IS THE ALL WHEEL DRIVE SYSTEM LIFTING ONE WHEEL OFF THE GROUND, THAT'S BULL. I'M DOING FIVE MILES AN HOUR. BOTH ISSUES HAVE BEEN GOING ON FOR OVER A YEAR. I DO NOT FEEL SAFE IN MY SUBARU. STAMFORD SUBARU HAS GIVEN ME AN IMPRESA AS A LONER AND I AM LOVING IT. I HAVE PUT SIX HUNDRED MILES ON IT AND NO PROBLEMS. PLEASE GET IN THEIR BUTTS TO FIX OR REPLACE MY FORESTER!!! THANK YOU IN ADVANCE... PS, THE COMPUTER CODE SAID INCORRECT GEAR RATIO FOR THE TRANSMISSION PROBLEM. IN ADDITION THIS HAS HAPPENED FIVE TIMES IN A YEAR AND FOUR MONTHS. VERY SCARY!!!

I PURCHASED THIS CAR 7/31/18. ON 12/21/18 (ODOMETER 3,427 MILES), THE FIRST MORNING WITH A HARD FROST, I FOUND THAT MY 2018 SUBARU FORESTER (STATIONARY AND PARKED IN MY DRIVEWAY) HAD DEVELOPED A CRACK OVERNIGHT FROM THE LOWER LEFT CORNER OF THE DRIVER'S SIDE UPWARD. (NO CRACK THE DAY BEFORE) I DROVE THE CAR 3 MILES TO WORK, CALLED THE DEALERSHIP WHERE I PURCHASED IT, AND SCHEDULED A SERVICE MANAGER EVALUATION APPOINTMENT THAT MORNING. I DROVE 12 MORE MILES TO THE DEALERSHIP. IN UNDER 3 HOURS, DRIVING TOTAL 15 MILES, SINCE DISCOVERING THE CRACK AND ARRIVING AT THE DEALERSHIP, THE CRACK HAD PROGRESSED UP AND ACROSS THE DRIVER'S SIDE OF THE WINDSHIELD. THE SERVICE MANAGER AGREED TO REPLACE THE WINDSHIELD AT NO COST TO ME, "AS A ONE-TIME GOOD WILL GESTURE". HE POINTED TO THE BASE OF THE CRACK WHICH BEGAN AT THE BOTTOM OF THE BLACK AREA BORDERING THE BASE OF THE WINDSHIELD, CLAIMED HE COULD SEE A CHIP, AND DUG HIS PEN INTO THE GLASS TO ENLARGE THE CRACK. TO ME, THIS ARE LOOKED MORE A FLAW IN THE GLASS WHERE BROKEN WINDSHIELD MAY HAVE HAD A FLAW HAD FLEXED DUE TO THE FREEZING WEATHER. HE DESCRIBED THE DAMAGE AS A CHIP ON MY REPAIR TICKET, WHICH IS MISLEADING IF AN ANALYSIS IS DONE ON THE CRACK, BUT IT SUPPORTS THE TICKET'S NOTE THAT THIS WAS A 1-TIME REPAIR AT NO CHARGE, WITH NO GUARANTEE OF FUTURE SIMILAR REPAIRS. THE DEALER DELAYED THE REPAIR DUE TO CHRISTMAS, AND THE CRACK CONTINUED TO PROGRESS ACROSS THE WINDSHIELD. REPLACEMENT INSTALLATION SCHEDULED FOR 12/26/18. ARRIVING FOR MY APPOINTMENT I WAS TOLD THE WINDSHIELD WAS ORDERED BUT THE DEALER FAILED TO SCHEDULE AN INSTALLER. THEY KEPT MY CAR UNTIL THE REPAIR WAS COMPLETED ON 12/28/19. THEY PROVIDED A LOANER CAR. RESEARCHING SUBARU WINDSHIELD CRACKS ONLINE, I LEARNED THAT SUBARU WINDSHIELDS HAVE A PROBLEM WITH SPONTANEOUSLY CRACKING, BEGINNING WITH A 2016 OUTBACK RECALL, BUT FORESTER OWNERS ALSO ARE REPORTING CRACKS.
PASSENGER SIDE SEAT SENSOR DETECTS PERSON SITTING IN SEAT AND TURNS ON THE AIRBAG WHEN THE SEAT IS EMPTY. NOTIFICATIONS TURNS ON AT CAR STARTUP AND WILL TURN ON WHILE VEHICLE IS MOVING. CAR WAS BOUGHT MAY 31ST, 2018. THIS BEHAVIOR STARTED ON THE FIRST COLD DAY IN MY AREA (ROUGHLY LATE NOVEMBER/EARLY DECEMBER 2018).

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.
