airbag alert for front passenger seat is lit and disabling the airbag. the seat was empty and dry with nothing in it.
Visibility/wiper, Feb 6, 2025
Windshield cracked starting in the black area under the driver's windshield wiper. Car was idling at a drive through, wipers were on. NOTE: car had fewer than 22,500k miles at the time, was likely around 22,485+. The crack continued to climb to the top edge of the window as my car sat on the driveway.

For the second time we were on the freeway at a hight speed and the car suddenly lost power, all the warning lights came on, and we had to get off the freeway (dangerously). We almost got hit, and other cars had to brake radically. We took it in to Subaru and they said the catalytic converter was bad. They replaced the catalytic converter, and when they took it for a test ride, they found that the SECOND catalytic converter was bad. Apparently they have two. The car must have suddenly lost power for them, too. We have 85k miles on the car, and the Subaru warranty for the catalytic converter is 80k. We're into it for thousands of dollars, but the MOST IMPORTANT reason I'm making this report is that SOMEONE IS GOING TO GET KILLED ON THE FREEWAY because of these failing catalytic converters, and it might not be people in the Subarus. The car just died at that speed in the left lane, and it was a miracle no one was killed. (I'm not sure if I have my date quite right. My calendar is not at hand). Note: Subaru is having a hard time getting the part, a delay, they say, of many days, so that makes me think that this is happening widely, and that these catalytic converters are getting replaced at an unanticipated rate.

We were driving at 70mph on the freeway, left lane, and suddenly the car lost power as if the fuel pump went out. We had to suddenly get over to the shoulder of the freeway, almost got hit, then limped along the shoulder until we called a tow truck which towed us 40 miles to Subaru dealer. The dealer looked at the car and "couldn't find anything." Now we are afraid to drive the car.
Suspension, Power train, Dec 11, 2024
The lower right control arm bushings failed on the vehicle and the transmission is leaking. The vehicle has been owned by only two individuals, and was purchased by me in 2021 as a certified pre-owned vehicle from a local dealer. In three years we have put about 12,000 miles total on the vehicle (average of 4000 miles each year for three years), and the vehicle is solely driven locally on surface streets. This appears to be a known issue as noted by Subaru owners expressing frustration in public forum about premature failure of the control arm bushings.
Power train, Dec 2, 2024
With no warning. my 2018 Subaru Forrester had its transmission lock up on me in the pouring rain while I was traveling 60 miles an hour. I purchased the car new in 2018, had it regularly serviced and it only has 4700 miles on it. If I was not buckled in, I would have gone through the windshield. The car spun around, jumped the divider and moved into oncoming traffic. Luckily, the other cars were able to avoid me. My local Subaru dealership said they can take a look at my car in 40 days. Until then, the car is dead and still locked up.

Blind Spot Detection goes on an off. Safety is impacted by the system going on and off. Took care to Subaru dealership
Engine, Nov 11, 2024, crash
Went to car wash,car was in nuetral after after wash finished I put the car in drive and it accelerated into the street at a very high rate of speed my foot was not on the gas.
Service brakes, Engine, Oct 25, 2024
After starting the car for the first time of the day, letting it warm for a minute or two, I started driving and when I went to stop at a stop sign about three blocks from my starting point I pressed the brake. The engine started to rev immediately so I had to stomp the brake to the floor and push the gear selector to the neutral position to avoid hitting a pedestrian and the dog she was walking. She was within 10 feet of the front of my car when I finally stopped. I have not taken it to a dealer yet since I am sure they will not be able to replicate the intermittent problem. There were no warnings of any kind that this was about to happen. I did note though, that the cold engine temperature indicator light on the dashboard was still illuminated.
Air bags, Oct 15, 2024
The contact owns a 2018 Subaru Forester. The contact stated that while driving at an undisclosed speed, the air bag warning light illuminated, and the air bag was not activated message was displayed. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 70, 000.
Fuel/propulsion system, Oct 15, 2024
The initial incident happened when I was accelerating uphill. When I pressed the gas pedal to accelerate, the car began jerking and sputtering. I released the gas pedal and let the car coast, as I was heading toward a stop sign. After I stopped and then accelerated the second time, the engine seemed to smooth out. Nothing further happened until about 1 week later. The second incident, I was 35 minutes into an hour-long drive. I was going around 45-55mph when the same issue happened suddenly: I pressed the gas pedal and the car started shaking and sputtering. If I released the gas pedal, the car was fine. All check engine lights came on and were flashing. I lowered my speed into the 30s, and the issue continued to happen, regardless of what speed I was driving at. If I was accelerating, the car was shaking a lot. At stop signs, the lights would turn off, but pop on as soon as I began driving again. I was able to make it to my destination and when I parked the car, it was shaking a lot while idling. It felt like the engine was about to die or shut off. It was late so I turned the vehicle off and left it parked for the night. The next morning, when I started the car, it was continuing to shake/sputter during idle and I drove it briefly to see how it ran. It continued to shake when pressing the gas pedal, however, the check engine lights were not on. Since I had to drive back home, I decided to take it slow and began the two-hour drive back. The engine again seemed like it wanted to die as I let the car warm up, but it did not shut off. Initially when driving, the car continued to have the same problem - shaking whenever I pressed the gas pedal, no matter the speed. The check engine panel lights did not come on, however, and after driving for about 20 minutes, the issue cleared up. I've only driven it as needed since then and it is currently running ok, but, given the numerous fuel pump recalls I'm concerned there is a defect with this model.
Air bags, Oct 8, 2024
Per the dealership, the occupant detection wiring harness resulting in the passenger side not activating despite a passenger sitting in the car. This causes a risk to the passenger as the airbag is not activated and the warning light goes on. This problem has been confirmed by the Subaru dealership. There is currently a recall for this issue for this particular issue and vehicle, however the VIN is not included. Additionally, when I look at the product campaign bulletin it outlines how to identify if there is a faulty harness. The harness ID falls in the vehicle within the the range of numbers that classifies it as a faulty harness. Despite this, Subaru refuses to replace it at their cost as the VIN is not covered by the recall notice.
Air bags, Seat belts, Seats, Oct 2, 2024
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.
Air bags, Sep 17, 2024
This is related to the ODS recall (October 3, 2019 NHTSA Campaign Number: 19V701000) where the sensor mat harness was replaced. Turns out the ODS sensor mat also needs to be replaced. The issue was happening intermittently throughout 2024 and I have brought the car in for service but the part is on back order for 2 months now.
Visibility/wiper, Sep 16, 2024
Windshield broke while sitting parked. Was not impacted by flying objects. Had to replace out of pocket.

The passenger-side front airbag Occupancy Detection System harness failed on my vehicle. The dealer charged me for a replacement, even though this part was recalled. They said they could not perform the repair free of charge because the recall was not listed for my VIN. I attempted to contact Subaru 12 days ago to request reimbursement, but I did not receive a response. I do not have the old part available, but I do have a photograph of the supplier code and date code on the harness. The codes are within the affected range, as indicated in recall bulletin WUM-98R (NHTSA ID 19V-701) Evidently, Subaru has failed to identify all of the vehicles affected by this defect. Passenger safety was put at risk because the airbag system would disable itself whenever somebody sat in the front passenger seat. Because the problem was intermittent, and because Subaru failed to notify me of the defect, this led to a delay in getting it repaired. The dealer diagnosed the issue and determined that the harness needed to be replaced. Whenever the failure occurred, the airbag trouble light turned on and the message "passenger air bag off" was displayed, even if there was a passenger in that seat.

I bought the car certified used from a Grand Prix Subaru in Hicksville, NY. They did not mention this issue. I’ve had the car for 2 years, drive it 1-2x a week, have it serviced regularly, etc. all of a sudden in the past week it’s needed a jump 2x, maybe a few days apart. My lights are on auto, always, & shut off when the car turns off after a few seconds. My interior lights are all set to off, after the first jump. Doors & cargo door are all closed well. Battery has been tested & they say it’s not bad & doesn’t need replacing. So what is draining the battery then? When the battery is dead, it’s completely dead. No turnover at all & the cargo door won’t open until it’s running & charged enough again. I’m shocked the cargo door can’t open without the battery!

The malfunction identified in NHTSA campaign number 19V701 has been continually malfunctioning again, beginning about a year ago. This is happening within a relatively short time after it was supposedly fixed. (Subaru's number for this recall is WUM-98). It is the exact same problem as previously identified in 19V701.

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.

LCA lower control arm front bushing on Right and Left front for 2018 Subaru Forester is a known issue with EVERY Forester. Mine had only 55K miles when the Right Front started shaking and now the left is doing so and I am only at 60K miles!!
Steering, Electrical system, Forward collision avoidance, Jul 6, 2024
Starting up the car in the morning after a long day stuck in traffic (over 100 degree F weather), moved about 5 feet then the eyesight system stopped working, rear braking stopped, and power steering gave out - the car started and the engine ran normally. The car was abandoned as unsafe until diagnostics could be performed and a different car was used to get around . That evening the car started up fine, also the next morning to reproduce conditions. Tested the battery, which showed "good" (93% charge/40%healthy). I suspect that, in the morning the A/C, headlights, radio, backup lights, etc... put a large draw on the electrical system resulting in a system wide shutdown of adaptive features - However loss of power steering is insane and can easily result in death if it happens while driving especially while making a turn if the driver is not prepared/strong enough to force it. The linking of non-critical system to help the driver to an essential system is just asking for trouble.

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)

2018 Subaru Forester has another cracked windshield. I do not drive this car a lot and all of a sudden there is a crack. It happened in 2021 too, it is exactly in the same spot this time. Subaru refused to fix it the last time, so I am not expecting them to fix it this time. This is not safe to drive when there is a crack like that. It is a matter of time before someone gets hurt or even worse because of the faulty windshield.

The contact owns a 2018 Subaru Forester. The contact stated that the front passenger’s side air bag warning light was intermittently flashing on the instrument panel with or without an occupant seated in the front passenger’s seat. The vehicle was taken to a dealer where a diagnostic test was performed; the diagnostic test discovered that the occupant detection system mat was defective and needed to be replaced. Upon investigation, the contact discovered NHTSA Campaign Number: 19V701000 (Air Bags) which was linked to the failure; however, the vehicle was not included in the recall. The manufacturer was then notified of the failure and confirmed that the vehicle was not included in the recall. The vehicle was not repaired. The failure mileage was approximately 57,000.
