2017 SUBARU FORESTER Electrical System Problems

There was a recall on this vehicle from 2022, and we did not own this vehicle at that time. Recall passenger side airbag contact under seat can cause fire or electrical issues. I contacted Subaru and they said the recall was satisfied in 2022. If that's the case, the repair piece must have been faulty as the issue has come back. The dealership I took the car to said they have seen about 4 of this same issue within the last two weeks. Subaru is unwilling to assist in this, and I cannot pay the 1800.00 dollars the dealership wants to repair this vehicle. I've asked more questions of Subaru since their answer and have not received a response. I would like to know why their website says this was complete July 15, 2025, not 2022. It was not complete in 2025, or we would have had the repair done....

Two incidents happened first battery died, we replaced the battery. Then Battery died again, we replaced the alternator on June 5, 2025. Then on Saturday September 13, 2025; all system lights came on at once on the dashboard then the battery died again. Car locks up and is stalled out. Cannot restart car, has to be towed. We replaced the battery cable and cleaned the terminals. Three months later, December 1, 2025; the battery light came on then all system lights came on at once, the battery died again. This happened on Interstate 95, it could easily have caused a crash. Car locks up again and is stalled out again. Cannot restart car again, has to be towed again. Something in the electrical is causing this, we do not know what.

Passenger airbag safety intermittently turns on stating that the passenger airbag is not able to deploy. If I turn the car off and on it goes away and doesn't turn until another time I start the car. Also detects a passenger in the seat when there is no passenger or weight in that seat. Overall some sort of issue with the airbag safety system in the front passenger seat. I will state no liquids have been spilled on the seat.

Previous recall for passenger ODS. Having continued issues with passenger airbag ODS not recognizing someone sitting there. Intermittently turns on and off even if no one is sitting there. Took it to a dealer and they want me to pay out of pocket for diagnostic and possible parts. Very high concern for even allowing someone to sit in the car (even my pregnant wife) in the case there was ever an accident.

The passenger airbag sensor often, but not always, malfunctions in my 2017 Subaru Forrester. Often it says PASSENGER AIRBAG OFF when there is a passanger. Occording to KBB Kelly Blue Book there IS a current RECALL in place for 2017 Subaru Forresters for EXACTLY this issue, including for my car - but when i typed in my liscnese plate in the NHTSA website, no unrepaired recalls showed up for my car.

I’m facing a really big issue here. I’ve been experiencing all the textbook issues in my vehicle for both of the recalls that did exist for my vehicle. I purchased my vehicle in [XXX], and I was just in to Walser Subaru in St. Paul MN where they said my recalls were completed in April 22, 2022. That is absolutely not true. I was at the dealership all day that day. So I called Miller hill Subaru in Duluth MN where it said it was done, and all they provided me with was the 2 dates I had brought it in for a general inspection and for an a/c issue. All I had done there was a transmission flush and both of those times were well after April 22nd. I purchased my vehicle from Anderson Auto in Rice Lake Township. So now I have my car with recalls that were...

The WUM-98 recall fix did not address the problem with the front passenger occupancy detection system. We, and many other Subaru Forester owners are continuing to experience problems post recall repair with the SRS Airbag light on, indicating error code B1760 "Occupant Detection Sensor Mat" failure. Subaru is not covering the cost of addressing this problem, and the entire seat frame and bottom cushion (that includes the sensor mat) are required to be replaced at the consumer's expense, with bills for repair in excess of $2,000. And, due to the high demand for this repair, parts are not available to perform the repair for as much as 6 months! This is jeopardizing the safety of occupants in the front passenger seat for extended periods of time while waiting for parts, whereby the airbag is not active due to the sensor mat problem. The original recall should have encompassed not only...

The Occupant Detection System (ODS) has failed in this 2017 Subaru Forester. The dealership tried replacing the wiring harness under a previous recall but it did not fix the problem. The ODS does not correctly identify when a passenger is seated in the passenger seat and therefore will not properly activate the passenger airbag. I ordered a replacement seat assemby in October 2023 but to date the dealership has been unable to obtain the part, and has been unable to fix the ODS malfunction in any other way.

Suddenly ignition starts having an issue where driver cannot pull out ignition key, which creates risky situations. If an emergency and unable to remove keys, then the driver is stuck. Apparently, this has been happening to Subaru's from 2014-2018 all over the country, and clearly defective design. Here is the TSB [XXX] Subaru should do a recall to prevent dangerous cases of drivers unable to pull their keys out, or having drivers "hack" the car, which remove important safety features. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

For the last few weeks on several occasions the ignition key remained stuck after parking and shutting off the engine. I was eventually able to release the key but was in a bit of a panic. I believe this should be a recall as I have read about this happening to many Subaru owners.

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...

I noticed that the airbag light was continuously illuminated on the dashboard of my Subaru Forester. I promptly took my vehicle to a certified Subaru dealership to have the issue diagnosed and resolved. After a thorough inspection, it was determined that the passenger seat bottom occupant seat mat required replacement to rectify the problem. Otherwise, my airbags would not inflate in the event that I would need them. I would like to emphasize that I have always maintained my vehicle in excellent condition and followed all recommended maintenance procedures. I have never exposed the seat to moisture or allowed any foreign objects to be shoved under it. Furthermore, I am the primary driver of the vehicle and rarely have passengers, which makes it highly unlikely for any undue stress or wear to be placed on the seat mat. Considering the circumstances, it is evident that this issue is a result...

During the last few months, the steering wheel has been locking, and I am not able to remove the ignition key. This happen when I stop and park the car, and want to turn the ignition off. I have to move the steering wheel from right to left or vice versa, or drive the car back and forward, until unlocks the steering wheel and I can remove the key. I just found through a web search that other drivers had similar issues.

I have a 2017 Subaru Forester 2.5i touring that seems to be plagued by a parasitic battery drain issue. I bought the car used in 2019 and successfully moved from Seattle to the Boston area in it shortly after the purchase with no issues. The dead batteries started during the pandemic, when the car was sitting undriven for extended periods of time. I’ve had the battery replaced multiple times, most recently in January of this year with a Diehard (3 yr warranty), and yet, once again, the car is dead and I had to call AAA yet again today. I'm at my wits end and cannot afford to continually purchase new batteries over and over again. My online research has produced dozens and dozens of stories about Subaru knowing about this parasitic drain and not admitting wrongdoing. I even found a class action lawsuit. Some folks online have reported having...

Key repeatedly gets stuck in ignition. Similar problem to other model years. Vehicle needs to be restarted and put in park several times to be able to remove key. Needing to start and move the car several times to remove the key puts pedestrians in the area at risk as visibility in parking spaces is often limited. It happens randomly, and is not regularly reproducible, but happens frequently. We have not yet had it serviced, and there are no warnings when it happens.

Malfunctioned component is Start / Stop switch. It is a safety Issue since not able to remove the key after stopping and parking the car. This creates issues when we need to get out of the car quickly. This issue can be reproduced. There was no warning or message.

We're having to consistently jump-start a battery that is only 4 months old. The problem has been consistent over the years (currently on our 3rd battery in about 5 years) but appears to have worsened after a DCM update to the Starlink system. Dealership has assessed the problem as parasitic battery drain (while the car is turned off) from the telematic module, but refuses to correct the issue.

Battery fails often, does not hold a charge, consistently registers as low battery. Occurs several times in 2021, 2022, and 2023, Have had to replace battery twice in 2 years.

We took our 2017 Subaru Forester on December 9, 2022, to change the ignition switch because our key continued getting stuck. It was covered under an extended warranty. The spark plugs were changed during the same appointment only to satisfy the maintenance agreement. Before we took our Subaru in, our vehicle was running at an optimal level, and nothing was wrong with how it drove. On December 10, 2022, we drove our car, and it started to hesitate and misfire. This has never happened before. We called the dealership, and they had us bring the vehicle back in. They performed a fuel injection cleaning and reset the computer. Once again, the same problem continued after picking up our vehicle. The same problem continued daily, and several calls were made to the dealership and trips to the maintenance service department. It is erratic when it happens, but we have experienced it...

The motor for the wiper fluid dispenser went bad. I took the vehicle back to be repaired and while they had the vehicle apart, I was informed that my entire wiring harness needed to be replaced. Now, my vehicle has sporadic issues such as windows not going down, the door locks engaging on their own, my fuel economy will suddenly drop to 19mpg from 28 mpg. Subaru initially stayed this was all due to the remote start I had installed at a retailer, this was after calling the dealership and they informed me that it was fine since my warranty had just expired. When I tried ro pursue something through the retailer, the dealership that had my vehicle denied saying that it was due to the remote start. So, I am stuck with a vehicle that has numerous problems, is not very safe and everyone says not my problem.

I have had to replace my Subaru Forester battery at least 4 times since I have owned it. The battery dies within a few days of replacing and I am forced to jumpstart the vehicle every time I want to drive. This has been happening since the day I bought the vehicle...

This is the same issue we are seeing with our other Subaru where we come out to drive and the battery is dead. We would jump the battery and be able to drive for the day and the next day the battery is dead in the morning. I replaced the battery several times over the last few year and the battery would die with a less than 2 month old battery. I was driving around in both cars with jumper cables permanently. After taking it to the dealer, the battery was in great condition, the alternator was charging properly and there is a known electrical issue with this model and year that is part of a class action lawsuit. I had to replace my rear gate module electrical unit because it was going on and off in the night and draining my battery. I will be looking to get re-eimbursed...

If you do not start the car everyday, the car drains the battery. Car must be jumped.nothing left on. It has a battery drain problem.

Battery drains if not driven approximately every 5 days. We have replaced battery three times. We’ve asked the local Subaru dealer a couple of times why the battery goes dead so quickly. Their response it’s a known issue. Not good that whenever we park the car or take it out of town we have to take a battery charger with us. This includes manually unlocking doors, climbing over back seat to get to the charger.

2 new battery drains dead just sitting in the driveway.

There appears to be a parasitic battery drain in the vehicle when it is stopped and all electrical systems are off (lights, heated seats, chargers etc) but the key is in the ignition. The most recent event was 7/20/2022 when the car was stopped for fueling and the key left in the ignition for no more than 10 minutes. Battery discharged sufficiently in that time that the car would not start requiring roadside assistance. Spoke with dealer who stated to keep the key 30 feet from the car (note, this is NOT a smart key car) and to ensure all is off as all computer electricals will continue to run even with the car off. Will be having a battery test next week but I see that this is a recurring issue for this make/model on this forum. The same problem happened in December 2021, although at that time the...

We have had issues with the battery draining since early on in owning the car. First the power windows stopped working and they replaced the battery. We are now having more battery issues and the care is in the shop.

The SRS airbag light is on, airbags disabled while driving vehicle with passenger in front. Sensor within passenger seat cushion is defective. Dealer says to fix passenger seat cushion needs to be replaced. Previous recall for harness already complete. Quoted $1400 to repair. 2017 Forester Premium, 78,000 miles

Our battery continually dies if we don’t drive it for 2 days. At first we thought it was just the battery but it keeps doing it. Our mechanic tried to fix it but it still happens. We had to buy a portable jumper because it happens so much. I see this also happens to Outback’s and other Subarus.

Purchased July 2016. Battery has failed to start car several times requiring a jump-start. Battery has been replaced 4 times (09/'18, 01/'19, 06/'19 & 03/'20). Currently vehicle is in shop for extended attempt to find source(s) of "parasitic" drain. Dealer reported aware of problem with certain Subaru models. A class action lawsuit has been initiated. Computer updates have over the years have not helped. This problem has the potential of stranding us when on a trip.

The Tire Pressure Monitoring System module failed which also disabled the key fob remotes. I had the TPMS module replaced 3 times. The first occurrence was on August 26th 2021 and was confirmed by the dealership Subaru Service Center. During the failure and malfunction of the module, the dashboard warned about not to drive because there is problems with the tires and key fob not working. This worried me because of the potential safety to me and others if I continued to drive with defective tires. Eventually I found out my tires did not have any problems. After the module malfunctioned the second time, the service center replaced it stating that the first module was defective. Several months passed by and the module failed the third time. I started to research online and found that other Subaru owners experienced similar issues and figured out that water such as from heavy...

I have a 2017 Subaru Forester that I bought brand new with only 5 miles on it at the time. Within the first year my battery needed replaced twice! I am still having this issue 5 years later and have purchased sometimes 2 batteries a year depending! The windshield also cracked within the first year I bought the car. I had it fixed and it cracked again this time not under warranty and the crack is in front of my eyesight sensor which makes my eyesight turn off which is very dangerous. I have seen MANY complaints on the windshield issue online with 2021 foresters. This is unacceptable. I am very unsatisfied with the company for not fixing this issue or making it right. I would not buy another Subaru or recommend anyone to buy one until they fix these problems.

2nd Battery in two years is dying while car is off. 1st battery did the same, and the dealership replaced it under warranty. There is a parasitic drain somewhere, that bleeds the battery while not in use. Every start is sluggish, and if a week goes by without driving the battery is totally dead. All user related electronic possibilities have been accounted for, i.e. cabin lights, trunk latch, etc

The battery is constantly dying and the car needs to be jumped often. The battery has been replaced and the connections have been cleaned multiple times. The battery can still be completely drained even if it is started every day.

My 2017 Subaru Forester has had its battery replaced twice. There is obviously either a problem with Subaru batteries, or there is something inherent in the electrical system of the vehicle that drains the battery. For a senior citizen, a dead battery when travelling is not only an inconvenience, but could be a major problem, especially in the winter months. I understand there is a class action lawsuit against Subaru for battery problems. I just want to add one more log to the fire.

Starting our 2017 Forrester has seemed sluggish recently, so we had the battery, starting system, and alternator checked. The starting system and alternator were in good working order. The battery's cold cranking amps (CCA) were below 400. The rated CCA for this battery is 525. It is less than 2 years old, but the check results indicated that it should be replaced. The check did reveal a "parasitic current drain" when the vehicle was turned off, which (most likely) has resulted in damage to the battery extensive enough to require replacement. To date, this has not left us stranded, but the potential for such an occurrence certainly exists. Further, there is a class action lawsuit concerning this issue currently making it's way through the court system. Originally, this lawsuit did not have any Forrester owners included. I plan to contact the law firm and be added.

I filed a NHTSA report on 7/19/2021 about having to replace my 2017 Subaru Forester's battery for the 3rd time in a 4 year old vehicle. I now am submitting another Complaint as now that #3 battery (all installed by Subaru Dealers) has FAILED, with #3 battery only 10 months old with approximately 6,000 miles driven with that battery. At about 8 months after the new battery install (battery #3), I brought vehicle to Subaru saying problem with battery (told it was "good") to only have it FAIL approx. 6 weeks later. While at Dealership I telephoned Subaru Customer Care indicating that the statistical probability of 4 batteries FAIL in a 2017 vehicle (purchased NEW), is indicative of something WRONG WITH THE CAR. I'm exhausted of being told this happens to batteries. No, it doesn't. I bought a Subaru for reliability, but this battery failure rate is unacceptable. #FixTheBatteryProblemSubaru

Battery dies often

Excessive battery drain/replacement. I have had to replace the car's battery five times since purchasing the vehicle new in 2017. The newest replacement battery has lasted 3 months. The vehicle was brought to Subaru dealership at least on two occasions to evaluate/diagnose the problem and Subaru was unable to detect any problem with the electrical system/battery.

The battery had died multiple times and we replaced it only to continue to have the problem. Dealer service says that we must be leaving the lights on or that we need to run the car more to recharge the battery. Being stranded in upstate NY with a dead battery in winter is a safety problem.

New battery and multiple replacement batteries fail to keep the electrical system charged when the vehicle is turned off. intermittent problem that happens unexpectedly, causing the consumer to be stranded and incur costs for alternate transportation, new battery, and roadside assistance. Multiple class action suits against the company are ongoing.

My 2017 Subaru Forester battery died in June 2019, leaving me stranded in a parking lot on a Sunday 50 miles from my home. The battery was still under warranty & was replaced by Subaru. I was told by the Service Manager that the batteries only last approximately 2 years. In early Oct 2021, my car sat idle for 10 days in the airport parking garage at JFK Int'l airport in NYC while I was away. When I returned home, the battery was dead, again stranding my approximately 50 miles from my home. I had to get a jump from a tow company who found that the red terminal on the battery was completely corroded. He advised that I would need to get a new battery when I returned home. I brought the car to Subaru the next day & was told by a tech in the service department that...

As far as I know, my vehicle is performing as designed, but I am quite serious in thinking this is a safety issue - the radio cannot be muted, or turned off, or the volume decreased, when the transmission in in Reverse, because of interference of its head unit with the backup camera. This is a hugely annoying distraction when trying to parallel park safely and quickly in dense urban settings. I want my backup lights on immediately, once I locate the parking spot I want, but time after time, I forget to turn off the radio before I start trying to park. I am the only owner of the car from new, and it now has about 69,000 miles on it.

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.

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...

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.

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.

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.
