WINDOWS GET LOCKED AND I'M NOT ABLE TO USE THE SWITCH TO UNLOCK THE WINDOWS AND EITHER SIDE. ISSUE WAS REPORTED. SUBARU CORRECTED THE ISSUE BUT IT STILL HAPPENS. ONCE SUBARU DEALER HELPED VIA PHONE CONVERSATION TO RESET BUT THIS IS A CONSTANT ISSUE. I FEEL TRAPPED IN MY CAR AND I HAVE TO OPEN MY DOOR TO REACH FOR A TICKET WHILE AT A PARKING LOT. CAN'T ROLE DOWN MY WINDOW AT THE GAS STATION. THIS CAN HAPPEN STATIONARY OR IN MOTION. THIS IS DEFINITELY A SAFETY HAZARD. ALSO, WHILE DRIVING THE MUSIC GOES TO A HIGH TO LOW VOLUME AND VISE VERSA EITHER ON IT'S OWN OR WHEN I HIT A BUMP. VERY DISTURBING AND SCARY AT TIMES ESPECIALLY WHEN I'M ON THE HIGHWAY.

FORESTER WAS PARKED IN UNDER GROUND PARKING GARAGE FOR BETWEEN ONE AND TWO WEEKS. THE BATTERY WAS COMPLETELY DEAD, NO SOUND AT ALL WHEN I TRIED TO START IT. THE ONLY DOOR THAT WAS LOCKED WAS THE REAR HATCH DOOR. NEIGHBOR BROUGHT A BATTERY CHARGER AND GOT THE FORESTER STARTED. FOLLOWING THAT, I DROVE IT TO THE LOCAL SUBARU DEALER AND ASK THEM TO CHECK AND SEE IF ANYTHING WAS DRAINING THE BATTERY. THEY CHECK EVERYTHING AND DID NOT FIND ANY PROBLEM. THE FELLOW AT THE SERVICE DESK SAID THAT STARTING A CAR IS THE BIGGEST DRAIN ON A BATTERY AND IF THE CAR ISN'T DRIVEN ENOUGH BETWEEN STARTUPS, IT TENDS TO BRING THE BATTERY DOWN. HE RECOMMENDED PARTICULAR BATTERY CHARGER WHICH HE SAID I COULD PURCHASE AT WALMART. SINCE I ONLY HAVE A LITTLE OVER ELEVEN THOUSAND MILES ON MY FORESTER, AND I HAVE NEVER HAD THIS SITUATION OCCUR WITH ANY OF MY OTHER AUTOMOBILES IN THE PAST. I DO WORRY ABOUT WHAT WOULD HAPPEN SHOULD I LEAVE MY CAR PARKED AT THE AIRPORT FOR A COUPLE WEEKS AND THERE IS NO PLACE TO PLUG IN A CHARGER. I STILL LOVE MY FORESTER.

THERE HAVE BEEN SEVERAL TIMES THAT THE CAR WILL NOT LOCK DUE TO A TYPE OF TRIP OR WIRING WITH THE LOCKING SYSTEM. WHILE THE CAR IS TURNED OFF AND STATIONARY, RIGHT BEFORE LOCKING THE DOOR, THERE IS A CLICKING SOUND AND THE DRIVER'S SIDE DOOR LIGHT FLASHES. THE DRIVER'S SIDE DOOR IS CLOSED, EVEN IF THE ELECTRICAL SYSTEM ACTS LIKE IT IS TRYING TO CLOSE THE DOOR. THIS PREVENTS THE CAR FROM LOCKING, DUE TO SOME TYPE OF TRIP IN THE DOOR SENSOR. IT MIGHT BE A TRIP BETWEEN THE KARR ALARM SYSTEM AND THE DOOR SENSOR INSTALLED IN THE CAR. I'VE ATTEMPTED TO REPAIR OR RESOLVE THIS SINCE I BOUGHT THE CAR AND IT IS HAS YET TO BE REPAIRED.

THE EYESIGHT HAD BEEN MANIPULATED TO A WARNING EVEN WHEN THERE'S NO OBSTRUCTION WHILE DRIVING FORWARD, WHILE BACKING UP IT GIVES A WARNING THAT SOMEONE OR A VEHICLE IS ADJACENT TO MY CAR. THESE ARE JUST A FEW OF THE PROBLEMS I ENCOUNTER. I HAVE AN IDEA WHO'S BEHIND THIS. BUT I CANNOT PROVE IT. SOMEONE VERY KNOWLEDGEABLE IN COMPUTER SECURITY WITHIN MY VICINITY. IT COMPROMISES THE SAFETY FEATURE OF THE CAR WHILE DRIVING AND EVEN BACKING UP IN MY GARAGE.

IT SEEMS THAT MY CAR HAS A POORLY DESIGNED/NOT-CURRENT-LIMITED USB JACK, WHICH FAILS TO PREVENT A PHONE CHARGING CABLE WITH SHORTED OR SHORTING-INTERMITTENTLY INTERVAL POWER WIRES FROM BURNING UP AND POSSIBLY CAUSING A FIRE. THE DETAILS OF MY BURNT-CABLE EVENT: ON TUESDAY EVENING OCT. 9, 2018, I GOT INTO MY CAR IN MY GARAGE. I THEN STARTED THE CAR. THE USB PART OF MY IPHONE CABLE WAS ALREADY IN THE CAR'S USB PORT, I BELIEVE. WHILE THE CAR WAS STILL IDLING IN PLACE, I THEN PLUGGED THE LIGHTENING END OF THE CABLE INTO MY IPHONE'S PORT TO CHARGE IT. I WAS STILL IDLING IN PLACE WHEN I HEARD A SOUND SIMILAR TO A PLASTIC BOTTLE POPPING INWARD OR OUTWARD AND STARTED TO LOOK AROUND IN MY CAR FOR WHAT'S GOING ON. I THEN, WITHIN SECONDS, I BELIEVE, STARTED TO SMELL A BURNING SMELL. I OPENED MY CENTER CONSOLE, SINCE THAT WAS THE MOST RECENT THING I HAD HANDLED, AND HAD PORTS IN IT, AND I SMELLED THE BURNING SMELL MORE. I QUICKLY PULLED OUT THE CABLE FROM THE USB PORT AND THE IPHONE ITSELF. I WENT ONWARD WITH THE NIGHT'S ACTIVITIES, AND THEN LATER THAT NIGHT, BACK AT THE CAR, INSPECTED THE CABLE AND SAW THAT THE LIGHTENING END (IPHONE END) WAS DISTORTED, WITH A WIRE PROTRUDING, AND A BROWN BURNT SPOT. I BELIEVE THIS COULD HAVE TURNED INTO A FIRE IF I HADN'T QUICKLY REMOVED THE CABLE FROM THE USB PORT.

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.
