2018 Subaru Forester Owner Complaints

Discovered (06/08/26) that the engine would not turn over without the accelerator being pushed down when warm from driving after resting 30-60 minutes. Car was taken to Capital Subaru. No codes were triggered. The throttle body was cleaned. No change. The Crankshaft Position Sensor was replaced, the ECU was reprogrammed, then the EVAP Purge Valve was replaced. A bottle of fuel injector cleaner was added to the gas tank by the dealership mechanics. No improvement. Then both CAM sensors were replaced. No improvement. All with no effect. Finally the injectors were pulled and a rail pressure test was conducted. The injectors were not holding pressure for more then 2-3 minutes. The warm start issue was fixed when the injectors were replaced on July 31, 2026.

- The passenger-side Occupant Detection System (ODS) sensor, which is part of the Supplemental Restraint System (SRS) airbag system, has failed. This component was previously replaced under a Subaru safety recall completed in May 2020. The SRS airbag warning light is now illuminated again, indicating a failure of the same system. The vehicle and failed component are available for inspection upon request. - The failure of the ODS sensor directly impacts the functionality of the passenger airbag system. This creates a significant safety risk because the airbag may not deploy correctly—or at all—in the event of a crash. This puts both the driver and any passenger at increased risk of serious injury or death. Since this is a critical safety system, its failure compromises the overall crash protection of the vehicle. - The issue is indicated by the illuminated SRS airbag warning light and has been identified as related to the Occupant Detection System. A dealership has confirmed that the ODS sensor requires replacement. The failure is consistent with known issues related to the prior recall repair. - I contacted Subaru of America regarding this issue, but they declined to provide assistance. It has not been inspected by police or insurance representatives, as no accident has occurred. - The SRS airbag warning light illuminated. There were no prior symptoms before the warning light appeared. The light has remained on consistently since then, indicating a persistent fault in the airbag system. - This issue is especially concerning because the component that failed was previously replaced under a safety recall. A recall repair should resolve a safety defect, not temporarily mask it. The failure of a critical airbag system component only a few years after a recall repair suggests that the original remedy may not have been a permanent fix. This raises serious safety concerns not only for my vehicle but potentially for other vehicles that received the same recall repair.

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.

I am filing a formal complaint against Subaru of America for refusing to remedy an active federal safety recall (NHTSA Campaign 19V701000 / Subaru Recall WUM98). My passenger airbag is currently disabled (DTC B1760). SRS light goes on and off and visit to the Sheehy Fredericksburg Subaru location confirmed that the occupant detection system is failing and I need a cushion assembly replacement. Subaru Customer Advocacy Department claims they already performed the initial wire harness replacement for this recall back in March 2020, but unable to provide me with the invoice or documentation of where this repair was done, and they are using this as their sole justification to refuse proceeding with Step 6 on Page 8 of the official recall bulletin—which explicitly mandates the replacement of the complete seat cushion assembly if the condition persists. When I referenced federal law (49 U.S.C. § 30120(g)(1)) regarding the 15-year statutory limit for free recall remedies, the representative denied coverage claiming 'it has been 6 years.' Subaru is actively denying a mandated safety remedy, ignoring its own technical guidelines, and endangering passenger safety.

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.

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 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 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 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 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.

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.

Incident

On October 3, 2023, I purchased a used 2018 Subaru Forester (VIN: [XXX] ) from Hengxin Auto Group, 210 39th St, Brooklyn, NY 11232, for about $19,500 including tax and fees. The dealer stated the mileage was 65,800 and printed that number on the contract. However, both the official NY DMV Title Record and the Carfax report showed 86,588 miles at the time of sale. This clear discrepancy proves the dealership intentionally rolled back or misrepresented the odometer reading. Later, the title was branded “mileage unknown.” After purchase, many severe issues appeared: chassis instability, transmission jerking, loud engine noise, high oil consumption, A/C malfunction, battery failure (replaced at my own cost), and worn tires that left me stranded. The dealer had advertised the vehicle as “excellent condition, only minor scratches,” which was completely false. I repeatedly contacted the dealer, but they only made partial chassis repairs and ignored all other problems. I paid significant repair expenses and eventually had to trade in the car on April 29, 2024, at Romano Toyota for $12,530.24, while still owing $13,705.58, resulting in a direct loss of about $9,283.78, not including additional repair and transportation costs. On October 2, 2025, I sent a formal demand letter to Hengxin Auto Group requesting compensation for odometer fraud and vehicle misrepresentation. The letter was received on October 9, but no response or resolution has been offered. The dealer’s conduct involves clear odometer fraud and nondisclosure of safety-related defects. I respectfully request NHTSA to investigate this case and take appropriate action to prevent similar consumer deception and safety risks.
