HAVING TROUBLE GETTING KEY OUT OF IGNITION. WHEN VEHICLE IS PLACED IN "PARK", I CANNOT TURN THE KEY ALL THE WAY TO THE "LOCK" POSITION SO IT CAN BE REMOVED. INSTEAD, THE KEY WILL STOP AT THE "ACC" POSITION, WHICH PREVENTS ME FROM TURNING THE CAR COMPLETELY OFF. EVEN WITH CONTINUALLY MOVING THE GEAR SHIFT BACK TO "NEUTRAL" THEN INTO "PARK", AS WELL AS TURNING THE KEY TO "ON" AND BACK, IT CAN TAKE SEVERAL MINUTES FOR THE KEY TO RECEIVE THE SIGNAL THAT ALLOWS ME TO TURN IT TO "LOCK" SO I CAN REMOVE IT FROM THE IGNITION SWITCH. THIS STARTED ABOUT 2 WEEKS AGO, AND NOW HAPPENS MOST TIMES WHEN I PARK THE VEHICLE.

WHILE VEHICLE WAS IN MOTION ON CITY STREETS AND HIGHWAYS THE REAR-END SHIFTS TO THE LEFT WHEN DRIVING OVER A BUMP (DRY OR WET PAVEMENT). IT ALSO SHIFTS TO THE LEFT WHEN DRIVING ON ICE. I KNOW CARS PERFORM POORLY ON ICE, BUT I'VE HAD MANY DRIVING CAREERS AND THIS PROBLEM IS UNIQUE AND NOT NORMAL FOR ANY CAR. ALSO IT HYDROPLANES EASILY. THE REAR TIRES (ESPECIALLY THE RIGHT REAR TIRE) WEAR UNNATURALLY. I HAVE TO REPLACE TIRES APPROXIMATELY EVERY 18000 MILES. THIS IS A MANUAL TRANSMISSION AND I RARELY HIT THE BRAKES. I DON'T ACCELERATE AGGRESSIVELY AND NEVER SLAM ON THE BRAKES. I USUALLY GET 60000+ MILES FROM MY TIRES. THE FRONT TIRES BY COMPARISON LAST 5-10 TIMES LONGER THAN THE REAR TIRES BASED ON THE AMOUNT OF TREAD WEAR AS COMPARED TO THE REAR TIRES OVER THE SAME AMOUNT OF MILES AS I DO ROTATE THEM REGULARLY. THIS CAR MAKES ME FEEL UNSAFE ON ICE AT ANY SPEED AND IS A LITTLE BIT HAIR RAISING JUST ON WET PAVEMENT. WHY IT WOULD SHIFT TO THE LEFT ON THE SMALLEST OF BUMPS AND EVEN ON DRY PAVEMENT (WORSE ON WET PAVEMENT) IS BEYOND ME. RECENTLY THE CONTROL ARMS AND TIE RODS HAD TO BE REPLACED AT 102K MILES. AFTER THAT REPAIR THE CHECK ENGINE LIGHT CAME ON AND AIR SENSORS HAD TO BE REPLACED. THIS CAR SEEMS LIKE A LEMON TO ME. I BOUGHT THIS NEW CAR FIGURING I WOULDN'T HAVE ISSUES I'VE HAD WITH USED CARS. I ENTERED A DATE OF 2016 WHEN THIS HAPPENED SINCE IT HAS BEEN HAPPENING SINCE I BOUGHT THIS CAR ALTHOUGH IT HAPPENS EVERY TIME I'M ON ICE.

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.

19V149000 · Exterior Lighting:brake Lights:switch

Feb 28, 2019

Subaru of America, Inc. (Subaru) is recalling certain 2014-2016 Forester, 2008-2016 Impreza sedans, 2012-2016 Impreza station wagons, 2008-2014 WRX sedans (including STI), and 2013-2017 Crosstrek vehicles. Exposure to certain contaminants may cause the brake light switch to malfunction, preventing the brake lights from illuminating and also preventing keyless ignition vehicles from starting and CVT/automatic transmissions from being able to be shifted out of Park.

Consequence & remedy

Consequence: Brake lights that do not illuminate properly will not alert other drivers that the vehicle is slowing or stopping, increasing the risk of crash.

Remedy: Subaru will notify owners, and dealers will replace the brake light switch, free of charge. The recall began April 15, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUE-90.

16V162000 · Engine And Engine Cooling:engine:gasoline:turbo/supercharger

Mar 21, 2016

Subaru of America, Inc. (Subaru) is recalling certain model year 2015-2016 WRX vehicles manufactured April 10, 2015, to October 21, 2015, and Forester 2.0XT vehicles manufactured April 10, 2015, to October 20, 2015. The turbocharger air intake duct may crack and possibly result in an engine stall.

Consequence & remedy

Consequence: An engine stall increases the risk of a crash.

Remedy: Subaru will notify owners, and dealers will inspect the turbocharger air intake duct, and replace it as necessary, free of charge, depending on the lot number found on the duct. The recall began April 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTA-62.

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.
