2018 Subaru Forester Problems

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.

- 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.

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.

Blind Spot Detection goes on an off. Safety is impacted by the system going on and off. Took care to Subaru dealership

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 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.

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

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

- Steering and suspension were affected. The car is available for inspection upon request. - My safety and the safety of others were affected by the fact that the car was shaking rather intensely while driving at highway speeds. I was worried a steering failure could occur. - My licensed mechanic diagnosed the problem as a right front lower control arm assembly problem with torn bushing. (Please see attached.) He replaced the assembly. Shortly thereafter, the steering wheel would feel occasionally loose and move on its own. The mechanic then did an alignment which did not help. The steering issue that came about after the control arm assembly was replaced is the subject of a complaint I filed with you yesterday: 11683647 - The problem being reported here has not been inspected by the manufacturer, police, insurance representative or others. - There were no warning lamps, messages or other symptoms of the problem prior to the failure. - Interestingly, the failure of the control arm assembly occurred at 51012 miles, right after the warranty ran out. My wife and I are seniors and we drive with care. Under the circumstances, this component of the car should have lasted much longer than it did. Now we worry the left side assembly may fail, especially since we have a loose steering problem that I reported yesterday.

1. The car's steering could be malfunctioning . The car is available for inspection upon request. 2. The steering wheel occasionally and without warning suddenly FEELS loose and "disconnected" from its ability to steer the car -- until I turn the steering wheel about a quarter to a half an inch and the steering FEELS normal again. I worry the issue (which so far has not interfered with steering the car) may worsen and possibly become hazardous. 3. I took the car to my regular licensed mechanic who did not experience the issue when he drove it. Nevertheless, the issue reported here exists as my wife and I have each experienced it. 4. The steering has not been inspected by Subaru, the police, insurance reps or others, other than my regular mechanic who has found no issues with the steering. 5. There were no warning lamps or messages prior to the issue first occurring except for the replacement of a tie rod by my regular mechanic, which may be coincidental. 6. This issue has existed since at least last February with no worsening of the condition. My regular mechanic has assured me there is no danger as he has checked the mechanical aspects of the steering (linkages, tie rods, etc.).

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.

Yesterday 6/19/25 I was driving out the driveway when the vehicle accelerated on its own, and not slowly, but like it had been punched. I was actually coasting at the time since I didn't want to stir up dust. My foot was not on the gas pedal. And it was not the floor mat. It happened on its own, the first time in 87,000 miles. It probably cannot easily be replicated as it was completely random, although now that it's happened once, it very well could happen again if there's a faulty or aging part or sensor. Neither the local dealer nor Subaru has acknowledged the problem (I called both today) but it's a SERIOUS safety issue. No check engine light or other means of warning. It just happened out of nowhere. Glad I was in the driveway and not in town waiting while a pedestrian was crossing the street.

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.

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.

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.

My drivers side seatbelt broke in a minor fender bender and was replaced.

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.

My drivers side seatbelt broke in a minor fender bender and was replaced.

Front end collision with car making an illegal left in front of our Subaru. Our car hood, bumper, head lights, grill and parts of the engine were smashed, with liquid draining out of the engine. My husband (wearing a seatbelt) hit his knee and shoulder on impact. Airbags failed - Not a single airbag deployed. A police officer helped him move car parts out of the street. Safety was at risk because my husband hit the dash. Car is at an independent service center now. We need to know how to get it inspected. There were no warning lights on dash prior to impact.

Wheel studs are of inferior quality, which leads to galling. Replacement of a wheel results in snapped studs. I have replaced three so far on two occasions within a week. Swapping to a spare in an emergency with broken studs will leads to accidents. As of now, I will need to drive with one broken stud to get it fixed. This is a known issue, the lugs were not over-torqued. The softness of the threads results in galling such that the threads tear out and fuse to the lug nut. How they have not issued recall/replacement/upgrades is astounding.

We just received the recall replacement on the car seat base, but our child is now practically grown out of it, rendering it now useless for the time we've lost in waiting for a replacement for the recall... My wife and I are not sure what to do here, but we've not really been able to use this car seat when we needed it most, and now that we have the corrected seat base, it's long past when it makes sense to have it. Is there a way to get a refund in some way for this?

Purchased my 4 tires, Good Year Assurance WeatherReady in Dec 2019 with 42,304 miles. My tire indicator light came on alerting of low tire pressure. Upon inspection of rear passenger tire, substantial dry rot on tire sidewall, inside. I only have 39,800 miles on the tire. Tire is a 60,000 mile tire. Tire is defective due to dry rot. Dry rot is so bad, tire does not hold air.

The contact owns a 2018 Subaru Forester. The contact stated while driving approximately 55 MPH, there was an abnormal sound coming from the rear wheels. There was no warning light illuminated. The vehicle was taken to a local dealer where it was diagnosed with needing the wheel bearings replaced. The vehicle was repaired. The manufacturer was informed of the failure and informed the contact that the parts would be replaced free of charge. The failure mileage was approximately 77,409.

During the winter of 2019 I was driving during a heavy wet snow storm. I had to stop every 5 -10 minutes to wipe off my headlights as they were covered in heavy wet snow. This was a safety issue as I needed to get out of my car on the side of the interstate near Hardin MT, where often many vehicles would pass near the car. For an all weather SUV, this is a safety issue. The lights did not produce any heat to melt the snow so that I could continue to drive in a safe manner. Have never run into this issue before with any vehicle. I have written Subaru about this issue after this occurred, but have never received any response.

A FEW INCIDENTS HAVE HAPPENED SINCE THE LATTER HALF OF 2020: WHILE AT A STOP LIGHT THAT TURNED GREEN, MY CAR STOPPED MOVING FOR A FEW SECONDS DESPITE PRESSING ON THE GAS PEDAL AND THE RPM WENT UP TO 6/ LOUDLY REVVED. I WAS ALMOST REAR ENDED AT THIS LIGHT.THE CAR HAS ALSO HAD THIS LACK OF MOVEMENT ISSUE ON THE FREEWAY WHILE IN TRAFFIC. MY CAR JERKS SEVERAL TIMES ON SLIGHT INCLINES ESPECIALLY AFTER SURPASSING 40 MPH. OFTEN TIMES, I CANNOT ACCELERATE PAST 40 MPH REGARDLESS IF THE DRIVE IS ON A FLAT SURFACE OR AN INCLINE. THE RPM WILL INCREASE, BUT THE GEAR FEELS LIKE IT WILL GET STUCK AND THE CAR MAKES A LOUD NOISE. THIS IS THE MOST NOTICEABLE GOING FROM 40 MPH TO 50-55 MPH. THESE INCIDENTS ARE ON CITY STREETS. HOWEVER, POWER OFTEN GETS LOST GOING ON TO FREEWAYS FOR THE SAME REASON. I CANNOT SURPASS 40 MPH WHEN ENTERING A FREEWAY AND WAS ALMOST SIDESWIPED ON THE DRIVER'S SIDE BY AN IMPATIENT PERSON ENTERING TOO EARLY WHERE THE ON-RAMP MERGES WITH THE FREEWAY BECAUSE OF THIS. WHILE ON A FREEWAY, THE CAR WILL CONTINUE TO ACCELERATE DESPITE ATTEMPTING TO SLOW IT DOWN BY PRESSING ON THE BRAKE OR COMING TO A COMPLETE STOP. THIS HAS ALSO HAPPENED ON CITY STREETS AND POSES A SAFETY ISSUE. THE ACCELERATION WHEN THIS HAPPENS IS MUCH FASTER THAN WHEN I TRY TO MANUALLY ACCELERATE THE CAR MYSELF IN OTHER CONTEXTS, LIKE MENTIONED ABOVE. I BELIEVE IT IS THE CVT AS THIS SEEMS TO BE A COMMON PROBLEM WITH CARS OF MY MAKE, MODEL, AND YEAR.

FIRST, DRIVING ON THE HIGHWAY THE AIR CONDITIONER STOPPED WORKING. SECOND, THE VERY NEXT DAY, THE VEHICLE BEGAN TO MAKE NOISES (SQUEALING) WHEN DRIVING IT ANYWHERE. STREETS, TURNS, HILLS ETC. THEN IT BEGAN RACE AND IT FELT AS IF THE BACK TIRES WERE RACING TO CATCH UP TO THE FRONT TIRES. THERE WAS LURCHING FORWARD. SHUDDERING. NO DASHBOARD WARNING LIGHTS CAME ON. I CALLED THE DEALERSHIP, THEN TOOK IT TO THE DEALERSHIP. IT WAS SCARY TO DRIVE IT THERE. I FELT LIKE THE TRANSMISSION WAS GOING UP. THIRD, THE TAILGATE, ( IN OR OUT) RELEASE BUTTONS WERE NOT WORKING CONSISTENTLY (REPEAT COMPLAINT). I LEFT THE VEHICLE AT THE DEALERSHIP AND TELEPHONED SUBARU OF AMERICA. THIS 2018; I HAD OWNED FOR EXACTLY TWO MONTHS. I HAD ONLY DRIVEN THE CAR APPROX 1200 MILES TOTAL. MILEAGE 47,000. THE DEALER HAS REPAIRED THE AC AND CVT TRANSMISSION. THE AC IS A KNOWN PROBLEM AND IT WAS THE CONDENSER THAT WAS LEAKING AND NEEDED REPLACED. THE CVT IS ALSO A KNOWN PROBLEM. THE SERVICE TECH TEST DROVE THE VEHICLE AND ABLE TO DUPLICATE CONCERN. HE FOUND THE RPM INCREASED AND THE SQUEALING COULD BE HEARD. VEHICLE WOULD SHUDDER. WHEN HE REMOVED THE PAN HE FOUND METAL IN THE OIL. CONFIRMING THE CVT (TRANSMISSION) NEEDED REPLACED. REPAIRS WERE MADE UNDER THE EXTENDED WARRANTY. GIVEN THE INFORMATION FOUND ON THE WEB REGARDING THESE PROBLEMS IT WAS IMPORTANT TO REPORT THAT THESE PROBLEMS CONTINUE. SAFETY IS CONCERN.

The contact owns a 2018 Subaru Forester. The contact stated that the front passenger’s side seat was extremely hot. Additionally, air bag warning light was illuminated. The contact also stated that the taillights were inoperable. While his wife was driving at an undetermined speed, the vehicle inadvertently lost power steering functionality. The vehicle was taken to the dealer where the taillight bulbs were replaced; however, the failure persisted. The manufacturer was not contacted. The approximate failure mileage was 90,400.
