I had a recall for my ODS sensor which controls the passenger airbag. I went and had it "taken care" of due to a recall. They did not fix it. My passenger airbag will still randomly shut off while I am driving down the road. I tried talking tk the dealership and they only say "we fixed the part we needed to replace". This is a huge safety issue. If I were tk wreck and my passenger airbag was turned off, someone would die.

B1760 code for ODS AIRBAG LIGHT IS ON AND THE LIGHT FOR PASSENGER AIRBAG OFF is On. There is a recall open for many other Subarus, same make, model & year. Safety concern for my daughter as she rides passenger. I had the problem diagnosed and documented receipt from ACS in Roseville California. I contacted Maita Subaru of Sacramento and they said there is not and wasn’t a recall for my Subaru. Very concerning, please help.

The contact owns a 2018 Subaru Forester. The contact stated the passenger’s side air bag warning light remained illuminated while his wife was seated in the passenger’s seat. The message that the passenger’s side air bag was disabled was displayed. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 135,000.

Subaru AC component cascading failures, starting 25,000 miles, light driving. July 2023 AC blowing hot. Recharged with dye. Subaru Dealer said no leak found. July 2024 AC expansion valve leaking and was replaced $500. (This failure would have directly effected the evaporator.) July 2025 AC system needed to be recharged. December 2025 evaporator replaced $1,680. March 2026 Compressor replaced $1,750. June 2026 Evaporator Sensor needs replacing $1,200.

June 2025: I proactively replaced the battery October 2025: Left the car parked for 17 days. Dead battery. Got a jump, drove for 2 hours. May 2026: Left the car parked for 10 days. Dead battery. Got a jump, drove to mechanic who replaced it under warranty. Saw article about Subaru class action lawsuit about this issue, so I'm reporting it. I will visit the Subaru dealer where I purchased to car and ask them about it and Subaru's plans for permanent repair.

The air conditioning system of my 2017 Subaru Forrester suddenly went out without warning. I noticed a defect when the A/C started buzzing with a high pitched sound and blowing semi-warm air instead of cool. I took my auto to a car repair shop. He provided this diagnostic analysis: Normal coolant level in the system. Performed Leak Detection Test- no detectable leak found at this time. A/C system pressures are too high on both pressure ports. A/C compressor has an internal noise. System is clogged. Ventilation interior cabin filter inspected and given a check at 24, 027 miles. Inspected , removed and replaced engine and cabin air filters at 41,600 miles. Inspected and removed and replaced engine and cabin air filters at 56,375. There are no other A/C related inspection or maintenance requirements to be accomplished (reference Subaru Forrester Maintenance/ Automation Subaru Arapahoe.My vehicle currently has 64,695 miles. My mechanic is currently working up an estimate for the A/C condenser, clutch, pump replacement... essentially the entire system. I consider this a latent defect and wish to be compensated for the repairs. Due to the weather, I wish to have the repairs accomplished and then be reimbursed. I have read articles on line stating this defect has become commonplace for 2017 and 2018 Subaru Forresters. This should be a recall item.

Cascading air conditioning system failures in my 2018 Subaru Forester. The failures occurred in the following sequence: 1. Expansion Valve Failure – The AC expansion valve failed, requiring repair. 2. Evaporator Core Failure – Shortly thereafter, the evaporator core failed, causing complete loss of air conditioning and requiring a second very costly repair. 3. AC Compressor Failure – Then the compressor started failing as well, resulting in a third major costly repair. Based on my research, a significant number of 2018 Subaru Forester owners have reported the same pattern of cascading AC component failures, suggesting a systemic design or manufacturing defect in the AC system. Subaru of America, to my knowledge, has not issued a recall.

The A/c compressor seized up causing the belt to break. Looked up online and it seems it's a common occurrence with this year and model.

Airbag light comes on due to some failure in the passenger seat. This vehicle year has had a recall on the same issue but this VIN number was not included for some reason. Another consumer posted his assessment which I have attached. My vehicle falls under his category. He has sold his since his was never resolved.

Passenger front seat. Airbag light is on when someone is sitting in the seat and seatbelt indicator dings when nothing is in the seat.

The CVT parking brake switch has failed. The failure leads to the inability to remove the key from the ignition switch when the vehicle is in park. This happens repeatedly, with the only temporary solution being to restart the car, and force the shift lever from "park" to "drive" and back again rather violently. Yes, the problem was confirmed by the dealer and by Subaru of America; the latter issued a limited 1-year warranty extension for the issue a couple of years ago, but it has expired without any further extension (before the problem first presented on my car). The vehicle was inspected by a dealer that confirmed the problem and wanted to charge me to repair it. There were no prior messages, warning lamps or other symptoms prior to the problem first happening.

The defect presents itself when the equipped data communications module (DCM) attempts to communicate with 3G cellular networks. As 3G networks within the U.S. are no longer functioning, the call will continuously fail even after the vehicle has been turned off, draining the battery and resulting in a no-start safety risk for drivers but in order to replace the DCM to the 4G it will cost upwards of $2000.

The AC compressor/condesor needs replaced and I see a lot of complaints on-line about this specific model- 2018 Forester. My kids and I were on a road trip in August 2025 when it stopped working. It was extremley hot even with the windows down and heat stroke became very real while we were sitting in bumper to bumper traffic. There was already a recall on this but now with the new part the AC stopped working and sounds very bad under the hood while the car is turned on. AC is very much needed during hot summer day.s

The AC compressor needs replaced and I see a lot of complaints on-line about this specific model- 2018 Forester so I am reporting in case it may help with a recall. Cost to repair is $2,000+. Right now it may only be covered under warranty or through a TSB goodwill. I will need to pursue with Subaru but wanted to report this in case it's helpful as there seems to be a lot of reports on this specific issue.

I was driving on the interstate when car started vibrating and making a terrible sound. Dealership advised both front lower control arm bushings were worn and had play. Had them replaced but because they are rubber technician advised this will most likely happen again. My car has only 46k. I bought it new in 2017.

The passenger airbag light in my 2018 Subaru Forester intermittently turns off and on, even when the seat is occupied. The vehicle has never been in a crash, and the airbags have not deployed. This issue raises serious safety concerns, especially since it may prevent the airbag from deploying in an accident while a passenger is in the seat. I raised this concern to a local Subaru Dealer, and they shared Subaru has not issued a recall on this make/model and the dealership has not provided a lasting fix. I believe this may be a defect in the occupant detection system or seat wiring.
