2017 Subaru Forester Powertrain (other) Problems

The shift guide plate in my 2017 Subaru Forester failed, causing the ignition key to become stuck and not release when the engine is off. The component is available for inspection upon request. The failure was confirmed by a Subaru dealer, who diagnosed the defective shift guide plate and provided a repair estimate of $685.23. The safety risk is significant - an inability to remove the key from the ignition can prevent the driver from securing the vehicle and creates confusion about whether the engine is truly off. There were no warning lamps or messages prior to the failure. The problem presented suddenly and has been reproducible consistently since it first appeared. This is a known manufacturing defect. Subaru acknowledged it by issuing an 8-year extended warranty extension (TSB 16-112-18R) specifically covering this component. My vehicle has only 71,000 miles - well below average for a 9-year-old vehicle - and falls just outside the 8-year window. I contacted Subaru of America requesting goodwill assistance, which was denied with no explanation beyond the warranty expiration. I am filing this complaint to establish an official record of this defect and the manufacturer's failure to stand behind it.

Subaru has acknowledge this is an issue back in 2016 due to the sealant us from the factory. Customer was quoted $1400 for the repair this known issue.

After driving the vehicle I will arrive at my destination. I will stop, continue pressing the vehicle break while moving the shifter from drive to park. Then, I turn the key to the off position in an attempt to remove my key from the Ignition. About 40-50% of the time, the key can not be removed. In order remove the key I will have to do one of the following: Option 1. Let my foot of of the break, pause, then press my foot hard on the break peddle, move to shifter from park to drive, while continuing to press my foot down hard on the break peddle, move the shifter back from drive to the park position. Often I will have to repeat this process several times to remove the key form the ignition or attempt Option 2.. Option 2. When Option 1 above does not work, with the vehicle turned off and I park, I will release my foot from the break, pause, press down on the break, start the ignition, place my vehicle in drive or reverse (depending how I am parked) and drive the vehicle 2-3 feet, stop and repeat step 1 above. Again, I many have to try this procedure several times. Option 3. After 5-10 minutes and several attempts, I will give up, turn the vehicle off, place it in park, and leave the car unlocked with keys in the ignition. I'm not sure why this has not been addressed prior as I have found several articles from 2008 to 2020 on the same issue, specifically on Subaru's.

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].

Once vehicle is stopped, transmission shifted to Park, and ignition key turned to off, ignition key will not come out of ignition. This has happened 8-19 times. Driver must start car, put in drive then back in park, turn off then key can be removed. I understand TSB 16-112-18R addresses this issue known to Subaru. It has not been inspected by a mechanic.

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.'

AFTER 20K MILES, TRANSMISSION HESITATES MORE AND MORE. BE CAREFUL AND TRY TO AVOID SITUATIONS WHERE YOU HAVE TO ACCELERATE QUICKLY. THE CAR DOES NOT MOVE OR ACCELERATE WHEN YOU HIT THE GAS PEDAL QUICKLY. CVT SLIPS, ESPECIALLY FROM REVERSE TO DRIVE. AT SLOW SPEEDS, IT JERKS THE CAR TRYING TO FIND THE RIGHT GEAR. THE PROBLEM BEGAN UNDER 10K MILES, AND I TOOK IT TO A LOCAL DEALERSHIP, THEY TOLD ME THAT IS HOW THE CAR DRIVES AND TOLD ME IT IS NORMAL. THIS IS NOT MY FIRST FORESTER, BUT DEFINITELY THE WORST. I CALLED SUBARU AMERICA, AND THEY SAID THERE IS NO KNOWN PROBLEM WHIT THEIR TRANSMISSION. I ALMOST GOT KILLED IN A HIGHWAY STOP AND GO SITUATION, WHERE I HAD TO ACCELERATE AFTER A SLOWDOWN, AND THE CAR DECIDED NOT TO. IF YOU OWN ONE, BE CAREFUL.

WHEN SHIFTING VEHICLE FROM REVERSE TO PARK, THEN TURNING VEHICLE OFF, THE KEY CANNOT BE FULLY TAKEN OUT OF THE CAR. THE ONLY WAY TO GET IT OUT IS TO RESTART THE VEHICLE, TAKE IT OUT OF PARK AND SLAM IT BACK INTO PARK. SUPPOSEDLY A SWITCH WITHIN THE SHIFTER THAT PREVENTS A SOLENOID IN THE STEERING COLUMN FROM OPENING. THIS IS ALL COVERED ON TSB 16-112-18 AND THERE ARE A LOT OF PEOPLE COMPLAINING ABOUT THE ISSUE ONLINE.

I WAS DRIVING ON THE HIGH WAY FOR ABOUT 2 HOURS, 70 MPH, GAS WAS AT ABOUT 1/8 FULL, BUT LOW GAS LIGHT ON. THE GEAR SHIFTER REMAINED IN D AND THE INDICATOR ON THE DASH SAID D. THE ENGINE REVVED AS IF IT WERE IN NEUTRAL AND WOULD NOT PROVIDE POWER TO THE WHEELS. THE CHECK ENGINE, TRACTION CONTROL, AND CRUISE CONTROL LIGHTS CAME ON, ALONG WITH POSSIBLY OTHERS. THE CAR BEGAN TO SLOW SINCE IT WAS JUST REVVING IN WHAT APPEARED TO BE NEUTRAL WHILE THE GAS PEDAL WAS PRESSED. EVENTUALLY I MADE IT TO THE SHOULDER. I TURNED THE CAR OFF FOR ABOUT 15 SECONDS THEN STARTED IT AGAIN. IT STRUGGLED TO START FOR A MOMENT LIKE THE BATTERY WAS LOW OR IT WAS COLD OUTSIDE, BUT STILL STARTED ON THE FIRST TRY. I SHIFTED INTO D AND BEGAN TO MOVE ON THE SHOULDER, BUT WHEN THE CAR WHEN OVER ABOUT 10 OR 15 MPH, IT WOULD REV AND NOT PROVIDE POWER TO THE WHEELS. I HAD THE CAR TOWED TO THE DEALER WHERE THEY ADDED GAS, TEST DROVE IT, SAID THERE WAS NOTHING WRONG, AND NOTHING THAT THEY COULD DO.
