2018 Subaru Forester Interior & seats Problems

I brought my vehicle to an authorized Subaru dealership (Byers Imports, LLC in Columbus, Ohio) to diagnose the reason for the airbag warning lamp illuminating. The dealer had the manufacturer's WUM-98 Safety Recall (NHTSA Campaign Number 19V701000) performed to remedy a defective Occupant Detection System (ODS) sensor harness.Despite the recall remedy being completed, the Supplemental Restraint System (SRS) airbag warning light re-illuminated on the dashboard, completely disabling the front passenger-side airbag.The dealership confirmed that the passenger-side airbag remains completely disabled and inoperable due to a hardware failure of the internal occupant detection sensor mat. Because the initial WUM-98 recall was previously marked as "closed" in Subaru's automated system, the manufacturer refused to cover the repair under the recall. I was forced to pay $1,258.34 out of pocket up front to order a replacement front passenger seat cushion assembly (Part #64139SG061LL) to restore basic airbag safety to the vehicle.The initial federal safety recall remedy failed to permanently correct the underlying safety hazard. The vehicle continues to exhibit the exact same life-threatening defect (disabled passenger airbag) targeted by the original recall, and the manufacturer is shifting the financial burden of this failed remedy onto the consumer.

The passenger seat Occupant Detection System (ODS) sensor failed, turning off the airbag and illuminating the SRS light. This is a known safety defect covered by Subaru recall 19V701 / WUM-98 for 2015–2018 Foresters built through August 1, 2017. My vehicle, a 2018 Forester XT Touring (VIN [XXX] ), has the same defect but Subaru and NHTSA do not list it as part of the recall. I waited nearly a year for the replacement seat to arrive, and Subaru of America only offered $500 goodwill assistance. I paid about $900 out of pocket for the repair. Given that this is a critical airbag safety system, I believe this vehicle should have been included in the recall population.

My airbag warning light comes on intermittently. My mechanic found it is due to a recalled part but my vin number is not listed on the recall even though it meets the criteria. Subaru Safety Recall WUM-98 NHTSA Recall ID 19V 70. The person in the passenger seat's safety is at risk if the airbags don't deploy in the event of a crash.

Subaru recall WUM98 was issued in 2019 to replace the ODS harness on my 2018 Subaru Forester. The part replacement was completed in in April 2020. The harness failed again in Oct 2024. It was replaced for the 2nd time. Now, my passenger air bag light is on for the 3rd time, and the dealership is indicating that the ODS mat is the culprit (not the harness). Subaru is not covering this under any open recall. Note that Subaru currently has an open recall WRA-24 for certain 2020 - 2022 Forester & Outback models to replace all (four) of the Occupant Detection System sensors in the front passenger seat. Since Subaru is saying that the issue in recall WRA-24 is the same as my issue, it is my belief that other models should also be included in this recall. It should also be noted that for WRA-24, they still don't have parts for many of the vehicles that need the seat assembly replaced, which may indicate supply issues. I was also told that Subaru does not have the seat assembly for my vehicle. The length of time for Subaru to get parts is unacceptable. Recall WRA-24 was issued by letter on May 21, 2024. It is my belief that they should also cover costs for rental vehicles until the issue is fixed.

THE ODS is not properly determining the status of the right front seat occupant. The airbag warning light is illuminated, and the front passenger airbag is deactivated even with a person sitting in the passenger seat. The ODS is also unable to determine if someone is in the seat and triggers the seatbelt alert when anything (even a purse) is on the seat. This exact issue was part of a Subaru recall WUM-98R, for 2015-2018 Subaru Foresters produced between January 20, 2015 – August 01, 2017. Subaru is claiming my vehicle doesn't qualify as it was not part of the recall even though I having the same issues as the recall and I own a 2018 Subaru Forester. Furthermore, as listed in the recall if a vehicle is part of the recall and is brought in for inspection "The part identification label affixed to the yellow sensor mat wiring harness is the focus of this inspection. If the date code is 18074 or BEFORE AND has the supplier code 6578 (RED box in photo) on it, the harness is NG must be replaced. Proceed to Harness Replacement Procedure as outlined below." The date code on my label is before 18074 and the supplier code is 6578. I am asking for your assistance in holding Subaru accountable to add my vehicle to the recall.

The sensor in the seat has been intermittently working for years and finally quit. It costs close to $2000 to fix and there is no way to switch the air bag to stay on. It seems this is an issue with other 2018 Subaru foresters and for some reason the recall did not apply to my VIN.

Incident

Mar 14, 2022

My 2018 Subaru Forester has a faulty passenger air bag sensor, which has been diagnosed by my local Subaru dealer, with a repair cost of $1,500+ for labor and parts. It has intermittently turned on and off again, but after getting a separate issue fixed by my dealer, they diagnosed this problem, and every time the car is turned on, the warning light is constantly displayed, and the passenger seat airbag light shows "OFF" even when someone is in the passenger seat. Upon research, this is a known and common issue with other Subaru Foresters with heated seats in the same model year (my Forester does have heated seats), but my VIN is not included in the Subaru recall for this specific repair. This greatly puts the passenger in my car at risk, as the sensor does not recognize that a person is in the seat while they are riding, and if we were to be in an accident, their airbag would not deploy. I am frustrated that this is a known, common safety issue that affects my model and year of car, but my VIN is not included on the recall list. I would expect that my car should also be included in the recall and fixed by the dealer at their expense as it is clearly documented many times on other 2018 Subaru Foresters.

The passenger seat, passenger air bags, and occupant detection system are failing. YES! Available for inspection. Passenger occupants are put at risk riding in my passenger seat as the seat does not detect if the seatbelt is on, or even if someone is sitting in the seat. The AIRBAG WILL NOT DEPLOY WHEN INTENDED! Issue was first brought to [XXX] at Subaru in Pasco WA, where they “could not do anything because it was not YET a recall.” As of [XXX], it has been confirmed by an ISC (Subaru of Hermiston, OR) My vehicle has been there since!!! They have not been able to fix the issue or get the part. There is no date of when the part is expected to available. We have been working with Subaru Customer Advocates who have extended my loaner car out 30 days, but after that. I will be OUT OF A SAFE vehicle. I have three children and NEED my passenger seat to be working effectively and SAFELY! Yes, there were warning lights that came on. The lights were on the dash. The red square with an “i” next to odometer and a red passenger air bag symbol below the other light that popped up. I have pictures and videos dated between June 2023 to March 2024 of the lights coming on. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Around 83,000 miles my passenger safety air bag warning sensor started coming on and off intermittently. It would happen both when a passenger was in the seat and when no one was in the seat. There have been no previous issues. I immediately scheduled my car to be diagnosed at the Subaru dealership and they notified me the passenger occupancy sensor pad is faulty and that it would cost $1,483.47 to replace. The dealer stated that the passenger airbag might not deploy if the sensor is not replaced. This puts the safety of the passenger at risk. I researched and found that there was a recall with 2016-2018 Subaru Forester SUV's with heated seats. Recall WUM-98. However, when I called Subaru they said that there were no open recalls on my car.

Incident

Nov 26, 2023

When there is a passenger in my Subaru Forrester, the Occupant Detection System deactivates the passenger airbag. When I researched the issue, I noticed there is a recall for Foresters but my specific vehicle doesn't fall into the recall. When reviewing Product Campaign Bulletin on the NHTSA website, the Harness Label Inspection Procedure states to inspect the label and if its has supplier code 6578 AND the date code before 18074, the harness must be replaced. My Forester has both the supplier code and the date code before 18074 but my vehicle doesn't have a recall associated with it so the Subaru service center won't replace it. I'm currently driving with a deactivated airbag and that can't possibly be safe. Please NHTSA, widen the recall!

The SRS passenger warning light comes on intermittently. Sometimes with a passenger the indication is the air bag is "ON" and everything seems to be fine. Sometimes with a passenger we get the message that the "SRS SYSTEM NEEDS TO BE CHECKED". And sometimes we get that message even without a passenger. This started at around 80K miles.

I'm unsure why this 2018 Forester wasn't one of the many manufactured that year recalled for an intermittent passenger seat air bag sensor malfunction since the focus of that recall remains the problem with this particular Forester: it has heated seats and displays an intermittent on/off passenger seat air bag light while a passenger is seated in that seat. The malfunction has been occurring for the past several years, however, our attempts to document and diagnose it have occurred much more recently. We took it to a dealership on 5/9/23; despite keeping it overnight and making numerous attempts to duplicate the problem (at a cost to us of $142) they were unable to do so. However, on 6/27/23, as I drove my wife a distance of approximately 150 miles and she sat in the front passenger seat, the airbag light displayed “off” almost the entire trip. Also, she and our son traveled about 400 miles between 16-19 June; he drove, she sat “front right”. During that trip the sensor light showed intermittently on and off and my wife was able to take time and date stamped photos of the sensor light from her point of view in the passenger seat; both when it was on and when it was off. I reported "all of the above" to the dealership and received a reply referring me to the "apparent" minimum weight limit needed for a passenger to trigger the sensor (100 lbs; I've seen 75), together with the explanation that "electronics" could interfere with operation of that sensor. Although my wife at times weighs just under 100 lbs, that weight limit doesn't explain why the sensor light is INTERMITTENTLY on and off on the same trip. At the very least, since she's now always concerned about failure of the airbag to inflate in the event of an accident, a recall/replacement/addition to the previously issued recall applicable to the exact same malfunction should be required. Based on dealership response, it will take an order from you before any additional repairs/replacements are made.

Since purchase in 2019, Subaru indicates that front passenger seat air bag will not turn on unless passenger is 65 lbs or more. My passenger seat air bag registers "on" if I place any item such as 1 gallon Milk (full bottle from store) in the passenger seat and furthermore, the Warning chime for passenger seat belt (not buckled) will sound continuously until I buckle the seat belt? Our local Subaru dealer will not look at issue unless we are willing to pay $100-$200 for diagnostic test? And then warns us we will have to pay labor and parts costs if sensor is found defective.

The contact's mother owns a 2018 Subaru Forester. The contact stated that the front passenger's side seat belt warning light failed to illuminate and alert the passenger to fasten the seat belt. The air bag warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the front passenger's side seat and sensor needed to be replaced. The vehicle was not yet repaired. The manufacturer was made aware of the failure and confirmed that a credit towards the repair would be provided. The failure mileage was approximately 23,000.

The passenger sensor light is on and Subaru says I need to replace the seat. There was a recall for certain vehicles but my Vin was not part of the recall - however, if the issue persists why isn't the recall expanded? Do we really want drivers like me to have to replace seats because Subaru is not living up to the standards - due to their faulty wiring? Please expand the recall.

Similar to recall notice WUM-98R (NHTSA 19V-701). Passenger seat occupancy sensor is intermittent indicating no passenger when one is present or, at times, indicating a passenger when none is present causing the seat belt warning and air bag system to malfunction. Currently, this occurs about 80% of the time. When I queried the internet about this issue, I found the referenced recall. Subaru claims that my vehicle is not included in the recall group. I have asked them to review this claim.

The rear seatbacks fold forward by pulling a knob on top of the seat beside headrest. Recently, as I was driving, my 6 year old child, who was restrained in a booster seat, reached up and pulled the knob, thus unlocking the seatback. I'm glad she asked, "what's this do?" or I may not have known that her seatback was not locked into place. We immediately pulled over to lock the seat into place. I see this as a potential safety hazard, that especially puts young children at risk.

Repeatedly the passenger air bag turns off even when car is in motion (warning lights turn on) with passenger in front seat. We have heated seats but apparently are not part of the recall that covers other Foresters with the exact same problem. Anytime we are in the car and it is deactivated it puts the passenger at risk if an accident would occur. This is extremely dangerous and can lead to death from a problem that the company appears to be aware of. It used to be we could turn the car off, have the passenger get out, restart the car, and the sensor will work, but now that does not happen. We would love to get rid of this vehicle but that is not an option at this time.

AS YOU CAN SEE FROM THE ATTACHED PHOTO (IMG_1295), THE DATE CODE ON THE HARNESS LABEL IN MY VEHICLE IS 18019 (19TH DAY OF 2018), THE SUPPLIER CODE IS 6578, AND THE SUBARU PART NUMBER (64084SG020) MATCHES THE PART NUMBER ON THE DEFECTIVE HARNESS LABEL ON PAGE 3 OF WUM-98R. ALSO, HOW CAN THE CUT OFF DATE FOR DEFECTIVE WIRING HARNESSES (74TH DAY OF 2018) BE 7 1/2 MONTHS AFTER THE LAST RECALLED VEHICLE WAS PRODUCED ON 8/1/2017? WHAT HAPPENED TO ALL THE DEFECTIVE WIRING HARNESSES MADE IN THAT 7 1/2 MONTH PERIOD ? AFTER SEVERAL EMAILS TO SUBARU CUSTOMER SERVICE, SUBARU STILL REFUSES TO ADMIT THAT THE WIRING HARNESS IN MY VEHICLE IS DEFECTIVE, STATING ONLY THAT THE VEHICLE WAS NOT MANUFACTURED BETWEEN 1/20/15 AND 8/1/17, EVEN THOUGH ACCORDING TO PAGE 3 OF WUM-98R THE HARNESS IS CLEARLY DEFECTIVE. NOTE ALSO THAT PAGE 3 OF PART 573 SAFETY RECALL REPORT 19V-701 CLAIMS THE WIRING HARNESS DEFECT WAS CORRECTED ON 2/19/2018, AND LISTS 17 RECALLED PART NUMBERS, BUT DOES NOT INCLUDE THE PART NUMBER IN THE PHOTOGRAPH OF THE DEFECTIVE HARNESS LABEL ON PAGE 3 OF WUM-98R (AND THE HARNESS LABEL IN MY VEHICLE).
