Making a sharp turn going slightly uphill from a full stop, the car moves forward enough to enter the intersection and then there is no throttle response. The car does not respond at all to the accelerator peddle. The engine does not stall but rpm drop to idle speed. After a few seconds, throttle response returns. Very dangerous as you move onto a highway because the car lingers in the intersection while the car behaves as if it has totally lost power. This has happened repeatedly but at random times.

My 2017 Subaru Forester has 52,000 miles driven. Recently the ignition key will NOT turn to start the engine. The transmission was in park and all the doors were fully closed. After 15 minutes trying several times to no avail it did finally turn to the right and the engine started. Also, previously a few times, randomly, the key would not turn all the way to to the left to turn the engine off. Again, the car was in park and I kept my foot on the brake while trying. Each time this happened I had to move the transmission from Part to Drive and back to Park again, (while keeping my foot on the brake) and the key finally turned all the way to turn the engine off. I am now bringing the car to a Subaru dealer service shop (in Annapolis, Maryland) to try to have them repair this problem once and for all. Thank you, [XXX].

I BOUGHT A CERTIFIED PRE-OWNED 2017 SUBARU FORESTER ON JUNE 19 2020. I HAVE HAD AN INTERMITTENT SAFETY ISSUE WITH THE VEHICLE NOT RESPONDING CORRECTLY WHEN I TRY TO ACCELERATE SINCE. WHEN I PRESS THE GAS PEDAL THE CAR WILL BEGIN TO ACCELERATE WITH MY RPMS RISING NORMALLY. THEN MY RPMS WILL START TO DROP WHEN THEY WOULD NORMALLY RISE AND MY CAR STOPS OR MAINTAINS THE ACCELERATION PRIOR. ONCE THEY HAVE DROPPED THEY WILL STAY THERE FOR A LITTLE AND THEN WILL SHOOT UP SUDDENLY AND RED LINE. I HAVE TRIED A VARIETY OF THINGS TO PREVENT THIS FROM HAPPENING; I HAVE TAKEN MY FOOT OFF THE GAS, KEPT THE SAME OR MORE PRESSURE ON THE GAS, AND BREAKING. REGARDLESS OF WHAT I DO THE VEHICLE RED LINES AND MY SPEED WILL EITHER DROP OR STAY THE SAME. I HAVE TAKEN THE VEHICLE TO SUBARU DEALERSHIPS ON 3 SEPARATE OCCASIONS AND IT WAS RETURNED TO ME WITHOUT DIAGNOSING OR REPAIRING THE PROBLEM. THE LAST TIME I DROVE MY VEHICLE IT DID THIS AGAIN AND THE RPMS RED LINING CAUSING MY ENGINE TO FAIL. I WAS ACCELERATED FROM A STOP AT A STREET LIGHT AND THE VEHICLE STOPPED ACCELERATING EVEN THOUGH I WAS PRESSING THE ACCELERATOR. THE RPMS REDLINED AND MY ENGINE BEGAN MAKING A TERRIBLE NOISE THAT WE LATER DISCOVERED WAS FROM UNREPAIRABLE ENGINE DAMAGE. THE VEHICLE HAS NOW BEEN AT THE DEALERSHIP FOR OVER A MONTH TO REPLACE MY ENGINE AND TRY TO FIX THIS ISSUE. EVERY WEEK THEY TELL ME I WILL GET IT BACK THE NEXT WEEK AND THEN SOMETHING ELSE FAILS OR CAUSES A SET BACK. I BOUGHT A SUBARU FORESTER BECAUSE OF ADVERTISEMENTS ABOUT HOW "SAFE" AND 'RELIABLE' THEY ARE SUPPOSED TO BE. INSTEAD I HAVE HAD NEAR MISSES WHEN MERGING ONTO THE INTERSTATE OR TURNING ACROSS TRAFFIC IN A BUSY DENVER INTERSECTION BECAUSE THE VEHICLE DOESN'T RESPOND AS EXPECTED. THE DEALERSHIP HAS IGNORED MY CONCERNS BY EITHER SAYING "THAT JUST HAPPENS WITH FORESTERS SOMETIMES" OR "WE CAN'T FIX IT UNLESS WE CAN REPLICATE IT.'

19V701000 · Air Bags:sensor:occupant Classification

Oct 3, 2019

Subaru of America, Inc. (Subaru) is recalling certain 2015-2018 Forester vehicles equipped with heated seats. An electrical connection in the front passenger seat for the Occupant Detection System (ODS) may loosen.

Consequence & remedy

Consequence: If the connection loosens, 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.

Remedy: Subaru will notify owners, and dealers will inspect and, as necessary, replace the ODS sensor mat harness, free of charge. The recall began February 11, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUM-98.

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.
