Frequently, when I put the car in park and try to turn the key to off, it gets stuck. At this point you have to move the shifter into and out of gear many times to try to get the key to go to off. Sometimes the key will not go to off so you need to leave the key in the ignition. This is dangerous because the car can still be shifted into neutral and move at this point.
The battery in my 2017 Subaru Forester was completely drained of power in 4 days of non-operation of the vehicle. The battery in question was installed on 10/4/2020 by my Subaru dealer to replace a battery that also had drained of power and would not take a charge. I presume the current battery was fully charged by my trip home to Arlington, VA from Philadelphia, PA on July 5, 2021. I tried to start this vehicle around noon on July 10, 2021 only to find that the battery was completely dead. The electronic key did not work. All internal screens are black. No response to key in ignition; not even a rattling noise. This is two dead batteries in less than two years of ownership. The current battery is only 9 1/2 months old.
Parasitic drag in Subaru Forester caused battery to die. Managed to get it jump started minutes before a downpour. Almost left my daughter and my wife stranded. A quick Google search showed this is a common enough problem amongst Subaru models so I decided to file a complaint as well
The battery of our Subaru Forester 2017 has died three times from June 26, 2021 through August 20, 2021. Simply put, from one day to the next, the battery is suddenly drained of all its power. From July 2017 when we first leased the car through May 2021, we had no battery problems. The safety issue is one of personal safety -- that we can't depend on the car, so we hesitate to use it. We don't want to be stranded somewhere unexpectedly because the battery suddenly dies, especially after dark. Our Subaru dealership ran diagnostic tests today (August 23, 2021) and claimed there is no problem, that the draw on the battery is within acceptable parameters. They will continue to test it tomorrow, but from conversations with the tech manager today, I feel certain they will claim there is no problem. The solution the technician suggested is that we drive the car more frequently. But our use of the car has been consistent since we first leased it. There must be a reason that the battery was fine for 48 months and now suddenly loses power unexpectedly and repeatedly. We understand from internet research we did today that this kind of battery problem is the subject of an ongoing lawsuit here in New Jersey against Subaru for several of their models from the years 2015-present. We think Subaru ought to be more forthright about the issue and do what's right for their customers. Please help us.
I'm having trouble removing the ignition key even with the car in PARK and pressing on the brake pedal, on level ground. It's intermittent and both keys are involved. The steering wheel still moves freely. The car is out of warranty and I have not asked a dealer about it. I belong to a Subaru Forester user group and it seems to be a fairly common problem. This could endanger me if I wanted to exit the vehicle quickly and couldn't remove the key. A carjacker could still start it just fine. No notices appear on the dashboard relating to this.
Battery Drain / Passive / When Vehicle is Parked The NEW battery drains passively when the car is parked. Will not start and needs a jump. This cycle has ruined a brand new battery.
The issue is sudden battery drain. The risk is being stranded. Unfortunately the drain happens randomly. The battery has been been replaced twice since 2017. Last battery replaced 11/19. I noticed this is an issue with this car and there are many complaints.
I've had to replace the battery three (3) times in a four (4) year old vehicle. I've had several calls to AAA for a jump start (to then get to Dealer to replace battery) and I had to purchase a rapid charger which I must carry in my car all the time in case the battery dies again. The problem with the battery began within the first year of purchase and has continued two times afterwards replacing the battery now 3 times Below I put the last time this happened. I've been stranded numerous times and I shouldn't have to keep jump starting my car. I've brought this concern to the Dealer (Sunset Subaru, Sarasota) and it is not taken seriously. In my opinion, this has been and continues to be a technical problem going back to the purchase of the vehicle in question.
My new battery completely drained over a weekend in my garage. I had AAA jump the battery and drove to their service center to check the battery to see if it was damaged. They said it was in great condition, no problems they could detect. A few days after the battery drain I found the passenger side window will not operate from the driver side console. I have an appointment with the Subaru dealership to investigate the problem. This is the second time I have had a complete battery drain on this vehicle. I am now on 2nd battery and there is only 18,867 miles on the vehicle. We could not find any reason for the drains.
The contact owns a 2017 Subaru Forester. The contact stated while attempting to start the vehicle, the vehicle would not start due to battery drainage. The contact stated that the battery had to be connected to a battery charger after each use. The contact stated that the check engine warning lights was illuminated. The vehicle was not diagnosed nor repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 22,375.
Battery drain. I've replaced the battery once around 30000 miles.
THE BATTERY ON MY 2017 FORESTER HAS BEEN REPLACED UNDER WARRANTY THREE TIMES AFTER BEING FOUND DEAD. ALL THREE TIMES SUBARU HAS SAID IT WAS A BAD BATTERY. THE BATTERY COULDN'T BE JUMPED AND MY MECHANIC SAID IT WAS AN ELECTRICAL ISSUE IF IT HAPPENED MORE THAN ONCE. LUCKILY IT WAS AT MY HOUSE ALL THREE TIMES SO ONLY A SIMPLE TOW. IF THIS HAPPENED 300 MILES OFF ROAD, IT WOULD BE A MASSIVE ISSUE.
BATTERY GOES DEAD AND MUST BE REPLACED IF NOT DRIVEN FOR SEVERAL DAYS. I HAVE REPLACED THE BATTERY TWICE.
IN NOV 2019 WE LEFT THE CAR PARKED FOR A WEEK AT THE CRUISE TERMINAL WHILE STATIONED OVERSEAS IN ITALY. WE WE CAME BACK, THE CAR WOULDN'T START AND HAD JUMPED. OVER THE NEXT SEVERAL DAYS THE CAR HAD DIFFICULTY STARTING AND WE ENDED UP TAKING THE CAR TO THE SUBARU DEALERSHIP IN FROSINONE, ITALY. THE SERVICE TECHNICIAN SAID THE BATTERY NEEDED TO BE REPLACED AND THAT WE WERE NOT THE FIRST FORRESTER OWNERS TO HAVE THE BATTERY REPLACED.
THE VEHICLE'S BATTERY DRAINS QUICKLY WHEN THE CAR HAS BEEN TURNED OFF, LEFT STATIONARY, AND NOT IN USE, WHICH RENDERS THE VEHICLE INOPERABLE.
TL* THE CONTACT OWNS A 2017 SUBARU FORESTER. THE CONTACT STATED UPON STARTING THE VEHICLE, THE KEY OCCASIONALLY SEIZED IN THE IGNITION. THE CONTACT BELIEVED THAT THE ISSUE WAS RELATED TO THE SHIFTER SENSOR OR THE KEY SENSOR. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER HAD NOT BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 38,000.*DT
2017 SUBARU FORESTER BATTERY DRAINS POWER AND LEAVES CAR TOTALLY DEAD ON SEVERAL OCCASIONS SINCE PURCHASE (1/2017). BATTERY DIED IN 2018 TWICE: ONCE DURING SUMMER AND ONCE IN NOVEMBER. (ONE TIME SUBARU SERVICE ROADSIDE ASSIST WAS USED, 11/18, AND ONE TIME A FRIEND CHARGED BATTERY). THIRD TIME BATTERY DIED WAS 3/19. BROUGHT CARE TO DEALER ON 4/29/19 WITH COMPLAINT OF BATTERY DRAIN. SUBARU TESTED BATTERY AND SAID IT WAS ALL GOOD AND WOULD NOT REPLACE BATTERY. IN 1/20 BATTERY AGAIN DIED AND ON 1/29/20 TOOK CAR AGAIN TO SUBARU DEALER WITH COMPLAINT OF BATTERY DRAIN. SUBARU CHECKED THE CHARGING SYSTEM AND UPDATES. BATTERY FAILED TESTING AND WAS REPLACED UNDER WARRANTY. ON 4/22/21 BATTERY AGAIN DIED. I CALLED SUBARU SERVICE MANAGER AND ASKED TO HAVE THE MY CAR TESTED TO SEE IF THERE WAS SOMETHING IN THE CAR THAT WAS DRAINING THE BATTERY. THE MANAGER REPEATEDLY TOLD ME THAT THERE WAS PROBABLY SOMETHING LEFT ON BY ME WHILE THE CARE WAS TURNED OFF.
I'VE BEEN HAVING MORE PROBLEMS WITH TAKING MY KEY OUT OF THE IGNITION. IT START OF HAPPENING ONCE IN AWHILE AND NOW EVERYTIME I TURN OFF MY CAR AND TAKE THE KEY OUT. I SEARCH ON THE PROBLEM AND READ ALOT OF PEOPLE HAVING THIS PROBLEM. I CALLED MY BRYAN SUBARU AND THEY SAID THIS HAS BEEN HAPPENING.
THESE MODELS HAVE AMPLIFIER SOUND ISSUES THAT ROUTINELY CAUSE THE AMPLIFIER TO FAIL AND CUT THE SOUND. THIS COULD DEFINITELY CAUSE A CRASH BY DISTRACTING THE DRIVER. THE AMPS ARE EXTREMELY PRONE TO FAILING AND CAUSE EAR DEAFENING TONES, NO SOUND, CRACKLING ETC. THE PROBLEM IS EXTREME AND DEALERS HAVE NO APPARENT WAY OF RECTIFYING THE ISSUE. THE INTERNET IS LOADED WITH CUSTOMERS REPORTING THIS INCLUDING MYSELF. THIS IS A MANUFACTURING AND DESIGN FLAW THAT SHOULD FIXED. NORMAL DEVICE FAILURE IS FINE BUT THIS IS OVER THE TOP. MY CAR WENT TO THE DEALER ROUGHLY 4 TIMES DUE TO THIS. MY VEHICLE PRODUCED A EAR PIERCING SOUND IN MID WINTER WITH THE WINDOWS UP AND LUCKILY I WAS ABLE TO PULL OVER TO GAS STATION WHILE ATTEMPTING TO PROTECT MY EARS AND SHUT OFF THE CAR. I KNOW THIS SOUNDS SILLY BUT THE SOUND SYSTEM IS ROUGHLY 500W AND THAT MIXED WITH THE HIGH PITCHED TONES IS EAR DAMAGING. I'M LUCKY I DID NOT CRASH. THE ONLY WAY TO OPERATE THE VEHICLE SAFELY WAS PHYSICALLY UNPLUGGING THE AMPLIFIER. PLEASE HELP.
THIS IS A 2017 FORRESTER. THE BATTERY KEEPS REPEATEDLY DYING. FOR EXAMPLE: HAD TO JUMP IN LAST NIGHT, DROVE IT FOR 45 MINUTES TO ENSURE IT SHOULD BE CHARGED BACK UP. IT WAS IN OUR GARAGE LAST NIGHT - AND TODAY, IT WON'T START AND WE CAN'T JUMP IT EITHER. AWAITING A TOW TRUCK. THIS BATTERY HAS REQUIRED A JUMP AT LEAST 5 TIMES IN THE LAST SIX MONTHS. AND THERE IS NOTHING WRONG WITH THE BATTERY. TALKING TO MULTIPLE SUBARU OWNERS REVEALS THIS IS A COMMON ISSUE - ONE SUBARU 'SOLVES' BY PUTTING IN A NEW BATTERY (AT MY COST) AND THEN IT WILL DIE TOO.
The vehicle does not recognize when it is park (a problem with a sensor down by the shifter) so it is nearly impossible to take the key out of the ignition. Although Subaru has created a TSB 16-112-18R that nhtsa is aware of, I want to report this happening to my vehicle. I believe it is a very dangerous situation to experience especially with children as passengers in the vehicle. I’ve had to bypass the sensor on my own due to the cost ($500+) of the repair ...
INTERMITTENTLY, THE KEY IN THE IGNITION WOULD NOT GO TO THE "OFF" POSITION SO THAT I COULD REMOVE IT AFTER THE CAR WAS IN "PARK." I WOULD HAVE TO MOVE IT (THE KEY) BACK TO THE "ON" POSITION, THEN BACK AGAIN TO THE "OFF" POSITION (BEYOND THE "ACC" SETTING).
INTERMITTENTLY, I CANNOT REMOVE THE KEY AFTER PUTTING THE VEHICLE INTO PARK. RESTARTING THE CAR, TAKING IT OUT OF PARK, AND PUTTING IT BACK INTO PARK (SOMETIMES REQUIRES MULTIPLE ITERATIONS) EVENTUALLY ALLOWS THE KEY TO RELEASE.
HAVE A 2017 FORESTER. AT LEAST A COUPLE TIMES A WEEK, THE KEY GET STUCK IN THE IGNITION. YOU CAN TURN THE CAR OFF, BUT YOU CAN'T REMOVE THE KEY. IF I START THE CAR BACK UP, AND SHIFT IT INTO DRIVE, AND THEM SLAM IT BACK INTO PARK, THEN I CAN TURN THE CAR OFF AND REMOVE THE KEY
AFTER SHUTTING ENGINE ON 2017 SUBARU FORESTER, AND PUTTING GEAR SELECTOR IN PARK, I WAS UNABLE TO REMOVE THE KEY FROM THE IGNITION AND IT WAS LOCKED IN ACCESSORY POSITION..AFTER MANY TRIES AND BY CALLING DEALER, PUTTING THE SHIFTER IN NEUTRAL THEN PARK ENABLED ME TO REMOVE IT. THIS OCCURRED ON ANOTHER OCCASION. THE SHIFTER PLATE GUIDE HAD TO BE REPLACED. COST WAS $662. MILEAGE ON THE CAR IS 31,000.
