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 rain leaked through the roof railing gasket into the area where the TPMS module is kept and shorted out. When I went in to the service center the third time, I explained my investigation and eventually the associate agreed that was the cause. I think without me telling them this, they would have just replaced the module stating another defective unit. This discovery had them not only replace the TPMS module, reprogram my key fobs but also replace the roof railings and it's gasket which they made me pay $960.43.

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 resu…

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

1PE19009 · 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.
