On the 2014-2021 Subaru Forester, the Lineartronic CVT (TR690) in 2014-2021 Foresters can develop shuddering, hesitation, and in severe cases, complete failure. Symptoms typically begin around 60,000-100,000 miles. The CVT chain can stretch, causing slippage and shudder during light acceleration. The torque converter can also develop issues. Subaru extended CVT warranty to 10 years/100,000 miles under Customer Satisfaction Program WTY-72. Multiple software updates have been released to address shifting behavior.
Common Symptoms
Shuddering during light acceleration at 15-40 mph
Hesitation or delay when accelerating from a stop
CVT whining or droning noise
Rough engagement into Drive or Reverse
Transmission warning light on dashboard
How to Fix
Have the dealer check for and apply the latest CVT software updates (TSB 16-103-17R). Perform CVT fluid change with Subaru CVT Fluid Lineartronic II (SOA427V1700). If shuddering persists, torque converter replacement or complete CVT replacement may be needed. Verify coverage under Subaru's 10-year/100,000-mile CVT warranty extension.

On the 2014-2018 Subaru Forester, separate from the well-known belt/chain judder, the TR580 CVT in the SJ-generation Forester suffers electrical failures in the torque converter lock-up circuit. The lock-up clutch solenoid (and its harness) degrades, so the converter clutch cannot be commanded cleanly. The signature is not a smooth shudder but a hard bucking or stumble on light throttle at lock-up speeds, a check engine light with P2764 (or related P0741/P2762 codes), and a flashing AT OIL TEMP warning that puts the transmission into a limp mode. Subaru acknowledged lock-up torque converter behavior in a design change (bulletin 16-90-13R) and rolled CVT coverage into the extended-warranty bulletin 16-107-17, which extends CVT coverage to 10 years/100,000 miles for covered concerns on 2014-2018 Foresters.
Common Symptoms
Bucking or jerking under light acceleration
Check engine light with P2764
Flashing AT OIL TEMP warning light
Transmission enters limp/failsafe mode
Shudder that feels like riding a clutch at a stop
How to Fix
Scan first — P2764 with a flashing AT OIL TEMP light points at the lock-up solenoid circuit, not the CVT chain, and the two get conflated. Have the CVT fluid checked and, where the bulletin applies, a valve-body/solenoid replacement performed rather than a whole-unit swap; the solenoid pack is inside the valve body. Reprogramming of the TCM is part of the documented remedy on some VINs. Critically, ask the dealer to run the VIN against the CVT warranty extension (bulletin 16-107-17, 10 years / 100,000 miles from in-service date) before authorizing any paid repair — many owners have had this covered at no cost. Use only Subaru CVTF; the wrong fluid will bring the fault back.
On the 2011-2018 Subaru Forester FB25, the 2.5L FB25 engine in 2011-2018 Foresters is widely reported for excessive oil consumption, often burning 1 quart every 1,000-1,500 miles. The root cause is defective piston rings that fail to maintain proper oil control. Subaru acknowledged the issue with TSB 02-157-14R and extended the powertrain warranty to 8 years/100,000 miles for affected vehicles. A class-action settlement (Oakes v. Subaru) covered ring replacement for qualifying owners. The oil consumption test (OCT) required by Subaru involves monitoring oil usage over 3,000 miles at the dealership.
Common Symptoms
Oil level drops significantly between changes
Low oil pressure warning light
Blue or grey smoke from exhaust on startup
Need to add 1+ quart of oil every 1,000-1,500 miles
Burning oil smell from engine bay
How to Fix
Request an oil consumption test (OCT) at a Subaru dealer. If consumption exceeds 1 qt per 3,000 miles, piston ring replacement is warranted. The fix involves replacing all piston rings and sometimes pistons (Subaru part 12006-AB270 short block assembly for severe cases). Check warranty extension and class-action settlement eligibility. Use Subaru 0W-20 synthetic oil and change at 3,000-mile intervals while monitoring.

On the 2009-2022 Subaru Forester, coil-on-plug ignition coils on the Forester are a common failure point. As the coil's internal epoxy/resin cracks with heat and age, the coil produces erratic or insufficient spark, causing single-cylinder misfires, rough idle, hesitation on acceleration, reduced fuel economy and a flashing/steady check-engine light. A frequently reported pattern is hard starting or stumbling when cold (below roughly 10°F) that improves once the engine warms. Note that a leaking spark plug tube seal (oil in the plug well) can prematurely kill a coil, so the two issues often appear together.
Common Symptoms
Rough idle and vibration at idle
Engine hesitation or stumble on acceleration
Flashing or steady check engine light
Hard starting or misfire when cold
Reduced fuel economy
How to Fix
Pull codes — P0301-P0304 indicate the misfiring cylinder; P0351-P0354 indicate coil circuit faults. Confirm by swapping the suspect coil to an adjacent cylinder; if the misfire follows the coil, replace it (coils cannot be repaired). Inspect the plug well for oil and replace the spark plug tube seal if oil is present so the new coil isn't ruined. Replace the spark plugs at the same time. Forester ignition coil part numbers vary by year/engine (for example 22433AA691 on 2013-2018 2.5L and 22433AA590 on non-turbo 2009-2010); confirm the exact PN by VIN.

On the 2011-2018 Subaru Forester FB25 2.5L, the FB25's hydraulic timing-chain tensioners can bleed down overnight, so on a cold start the chain is momentarily slack and slaps the chain cover/guides, producing a metallic rattle for the first few seconds until oil pressure builds. A brief rattle is common; a rattle that persists 3-4 seconds or grows over time indicates worn tensioners and guides and risks chain skip if ignored. Owners report dealers replacing both tensioners, both chains and all guides on higher-mileage cars.
Common Symptoms
Metallic rattle/clatter for a few seconds at cold start
Rattle that lengthens or worsens over time
Rattle returns after the car sits overnight
Occasional rough running if chain has stretched
Noise reduced after an oil change
How to Fix
Use the correct-grade oil (0W-20) and keep oil fresh; many owners find a brief startup rattle is normal. If the rattle lasts more than ~3 seconds or worsens, have the timing chain tensioners, chains and guides inspected and replaced as a set before a guide breaks or the chain jumps time. Confirm oil pressure and check for sludge that can starve the tensioners.

On the 2011-2024 Subaru Forester FB25, the boxer engine's two valve covers face outward and sit low on each side, exposing the cork/rubber valve cover gaskets and the spark plug tube seals to heat cycling and the path of any leaking oil. As these seals harden and shrink, oil seeps out and visibly drips onto the exhaust (burning-oil smell from under the hood) and — more importantly — pools down inside the spark plug tubes. Oil in the plug tubes saturates the plugs, boots and ignition coils, leading to engine misfires, rough idle and a check-engine light. Owners report this on both early FB25s and surprisingly low-mileage newer cars (cases as early as ~17k-50k miles documented on the owners' forum). The valve cover's external location makes the leak a frequent dealer/independent repair.
Common Symptoms
Burning oil smell from engine bay
Oil dripping/residue along the lower side of the engine
Rough idle and engine misfire
Check engine light with cylinder misfire codes
Oil pooled in spark plug wells when coils are removed
How to Fix
Remove the affected valve cover and replace BOTH the valve cover gasket AND the spark plug tube seals at the same time (replacing only the cover gasket and leaving old tube seals lets oil keep reaching the plugs). Inspect and replace any oil-soaked spark plugs and ignition coils. The FB25 valve cover gasket is OEM 13294AA050 (supersedes/cross to 13294AA053); the gasket set that includes the spark plug tube/washer seal is 13293AA051. Clean oil residue off the block and re-torque the cover to spec.

On the 2014-2018 Subaru Forester, on Foresters operated in road-salt regions, stone and debris impact chips the protective coating on the rear coil springs. Bare spring steel then pits and corrodes, and a section of the lower coil can fracture and break away. A broken spring end can contact and puncture the rear tire and degrades handling and ride height. Subaru issued recall/campaign WUT-05 covering roughly 499,000 vehicles to replace the rear springs with corrosion-resistant units.
Common Symptoms
One rear corner sitting noticeably lower
Pieces of spring metal found on the ground near the car
Clunk or harsh impact over bumps
Tire damage from a broken spring end
Sagging ride height at the rear
How to Fix
Check the VIN for open recall WUT-05 and have the rear coil springs replaced free with the redesigned, better-coated springs. Inspect for telltale signs: a corner sitting low, metal fragments on the ground where parked, or a clunk/sag over bumps. Out of warranty, replace springs in axle pairs and treat/undercoat the new springs in salt climates.
On the 2014-2022 Subaru Forester, foresters routinely wear the inner edges of the rear tires bald at low mileage (often 20,000-30,000 miles). The rear suspension allows toe adjustment but not camber, and the factory frequently leaves the rear toe set too aggressively, scrubbing the inner shoulders. Because owners can't see the inner edge, the wear is often discovered only when tires are flipped or replaced, leading to premature, uneven tire replacement.
Common Symptoms
Rear tires worn bald on the inner edge
Uneven rear tire wear at low mileage
Tire noise/feathering on the inside shoulder
Shortened tire life despite rotations
Cupping on rear inner tread
How to Fix
Get a four-wheel alignment with the rear toe set to the low end of spec (near zero) rather than the factory default, ideally early in ownership. Inspect inner rear tire edges at every rotation. Where toe is out of range and not adjustable enough, aftermarket rear toe/camber adjustment hardware can bring it into spec. Maintain correct tire pressures, since under-inflation accelerates the wear.

On the 2009-2018 Subaru Forester, foresters from 2009-2018 develop a persistent clunking or knocking noise from the rear suspension when going over bumps, rough roads, or speed bumps. The cause is worn rear lateral link bushings and rear stabilizer bar end links. The rubber bushings dry out and crack, allowing metal-on-metal contact. The noise is often misdiagnosed as strut or shock failure.
Common Symptoms
Clunking from rear over bumps and rough roads
Hollow knocking sound at low speeds over uneven surfaces
Rear end feels loose or vague in corners
Visible cracking or deterioration of rear suspension bushings
How to Fix
Replace rear lateral link bushings (both inner and outer on each side). Replace rear stabilizer bar end links. Whiteline polyurethane bushings are a popular upgrade that lasts significantly longer than OEM rubber. If noise persists, check rear subframe mounting bushings. Torque all bolts to spec with the suspension loaded (wheels on ground or suspension compressed to ride height).

On the 2014-2016 Subaru Forester, silicone gas outgassed from in-cabin consumer products (cleaners, air fresheners, protectants) can seep into the brake lamp switch housing, where it forms an insulating silicon-dioxide deposit on the contact terminals. Because the brake switch on these Foresters feeds the transmission shift-interlock and the push-button ignition interlock in addition to the brake lights, a failed switch can leave the brake lights dark, prevent shifting out of Park, and on keyless models prevent the engine from starting. Subaru recalled roughly 1.3 million U.S. vehicles for this defect.
Common Symptoms
Brake lights do not illuminate when pedal is pressed
Push-button start cranks nothing / engine will not start
Shift lever stuck in Park, won't release
Intermittent cruise control or hill-hold dropout
No diagnostic trouble code stored
How to Fix
Free recall repair under Subaru campaign WUE-90 (NHTSA 19V-149): the dealer replaces the brake lamp switch with a revised unit using fluorine grease that resists silicone contamination. Out of warranty/recall, the switch itself is an inexpensive part (~$30-50) but diagnosis of a no-start or no-shift complaint is often misattributed to the battery, starter, or ignition before the switch is found.
On the 2003-2018 Subaru Forester, the wiring that feeds the tailgate runs through a flexible rubber boot between the body and the gate on the passenger side. Every open and close flexes those conductors, and over years the copper work-hardens and fractures inside the insulation, so the wire looks intact from outside. Owners lose several functions at once or intermittently: rear defogger dead, rear wiper not parking or not working, rear gate not locking with central locking, cargo lamp out, backup lights out, and on later cars the backup camera. A chafed conductor shorting to the gate can also blow the brake-light or accessory fuse repeatedly. It is easy to misdiagnose as a failed motor, switch or camera because the affected component tests fine when powered directly.
Common Symptoms
Rear defogger stopped working
Rear wiper dead or will not park
Rear gate will not lock or unlock with central locking
Backup lights or cargo lamp inoperative
Repeatedly blown brake-light fuse
Backup camera intermittently drops out
How to Fix
Pull the rubber grommet/boot at the passenger-side hinge area and flex the loom while probing continuity — broken wires show up right at the bend point. The durable owner-level repair is to cut back each broken conductor, splice with lap solder joints, and cover every joint with heat-shrink, then re-route with a little slack so the flex point moves; that repair is typically about an hour's work. Alternatively replace the rear gate harness (Subaru part 81812AG03C on the applicable years) — the part itself is inexpensive, the labor is the cost. No recall or warranty program covers this wear failure.
On the 2014-2022 Subaru Forester, forester moonroofs drain rainwater through small tubes routed down the A/B pillars to discharge under the car. The corner drains clog with pollen, dirt and tree debris, or a tube pops off its nipple at the sunroof gutter. Water then backs up and overflows into the headliner and cabin, soaking the carpet, fogging windows, and — because water pools near floor electronics — sometimes causing electrical gremlins. The leak is often misdiagnosed as a seal failure when it is really a blocked drain.
Common Symptoms
Water dripping from the headliner or A-pillar in rain
Wet front or rear floor carpet
Musty smell / interior fogging
Water heard sloshing in the roof or pillars
Intermittent electrical faults from wet floor connectors
How to Fix
Periodically clear the four sunroof drain tubes (low-pressure compressed air or a soft trimmer line) and confirm flow exits under the vehicle. Re-seat any tube that has detached from the gutter nipple. Dry out wet carpet/padding promptly to prevent mold and corrosion of under-seat electrical connectors. Replace the perimeter seal only if drains are confirmed clear and water still enters.

On the 2014-2018 Subaru Forester, on power-liftgate Foresters the gas-charged lift struts lose pressure prematurely. The gate opens under power but then sags or falls shut under its own weight once fully open, and the problem worsens in cold weather as strut gas pressure drops. A weak or failing strut can also confuse the obstruction-detection system, causing the powered gate to reverse or beep. Subaru issued a warranty extension on the liftgate struts for affected vehicles.
Common Symptoms
Liftgate slowly sags or falls shut when fully open
Worse in cold weather
Power gate beeps and reverses partway
Gate feels heavy / hard to hold up manually
Gate won't latch in the open position
How to Fix
Check for the liftgate-strut warranty extension and have weak struts replaced. The gas struts/lift supports are replaced in pairs; the gate must be securely propped or held during the job because it is heavy. If the gate also beeps or stops mid-travel after the struts are good, suspect the power drive unit or obstruction sensor rather than the struts.

On the 2009-2018 Subaru Forester, forester wheel bearings (both front and rear hub assemblies) fail prematurely, often well before 100,000 miles. The most consistent symptom is a low-pitched grinding, humming or 'airplane' droning noise from the affected corner that grows louder with speed; rear bearing wear is often felt as a vibration under the seats. The noise typically changes pitch or volume during a left/right lane-change maneuver (which distinguishes it from differential whine). Subaru acknowledged a contributing root cause: unevenness/distortion of the bearing backing plate surface affects hub/bearing concentricity after the axle nut is torqued, allowing a 'howling' bearing to develop over time. Water/dirt contamination from failed seals and improper axle-nut torque accelerate the wear. Subaru issued a service bulletin acknowledging the rear bearing/backing-plate concern.
Common Symptoms
Grinding or humming/droning noise from a wheel that gets louder with speed
Noise changes during left/right lane-change maneuvers
Vibration felt under the seats (rear bearing)
Knocking or clunking when cornering
Uneven/inner-edge tire wear
Play when rocking the wheel by hand
How to Fix
Diagnose by lifting the wheel and checking for play/roughness, and by listening for a noise that changes during gentle S-turns at 30-65 mph. The fix is replacement of the complete wheel hub/bearing assembly (sold as a unit). On 2014-2018 Foresters the front complete hub unit is OEM 28473FL040 (supersedes 28473FJ000/28473FJ020); reuse a new self-locking axle nut and torque to spec. Have an alignment checked, as poor alignment and unbalanced tires accelerate bearing failure. Replacing in pairs is common practice.

On the 2009-2019 Subaru Forester, the front CV (constant-velocity) axle boots on Foresters crack and tear with age and from suspension flex and road debris. Once the boot splits, grease slings out and dirt/water get in, so the now-dry CV joint wears and produces a clicking or popping that is loudest during tight, low-speed turns. Left unrepaired the joint fails completely, risking loss of drive to that wheel. Owners frequently spot a ring of slung grease on the inner fender or underbody before any noise.
Common Symptoms
Clicking or popping during tight low-speed turns
Grease flung onto the inner fender/underbody
Torn or cracked rubber CV boot
Rhythmic grinding under acceleration when turning
Vibration that worsens with speed (failing joint)
How to Fix
Inspect the inner and outer CV boots at every service for cracks or grease slinging. A freshly torn boot caught early can be re-booted and repacked, but a joint that already clicks needs the CV joint or, more commonly, a complete remanufactured/new front axle assembly (sold per side). Use quality OEM-grade axles; cheap aftermarket axles are a known repeat-failure complaint.

On the 2011-2021 Subaru Forester FB25, foresters commonly throw a P0420 'Catalyst System Efficiency Below Threshold (Bank 1)' code and an illuminated check-engine light. While the converter itself is the part that degrades, the underlying root cause on FB25 Foresters is frequently the well-documented excessive-oil-consumption defect: burnt oil and unburned fuel coat and contaminate the catalyst, reducing its efficiency until it can no longer pass the downstream O2 sensor's efficiency check. Coolant intrusion and exhaust leaks can produce the same result. Subaru issued a service program (WVI-19/WVI-19R) extending the catalytic converter coverage to 10 years/100,000 miles on certain affected vehicles, and the related Yaeger oil-consumption settlement (2011-2014 models) extended engine warranty to 8 years/100,000 miles.
Common Symptoms
Check engine light with P0420 stored
Failed emissions/smog test
Rotten-egg/sulfur smell from exhaust
Reduced fuel economy
Often paired with excessive oil consumption
How to Fix
Before condemning the converter, rule out cheaper causes: a lazy/failed rear O2 sensor and exhaust leaks can both mimic P0420. Verify the engine is not consuming oil at an excessive rate (a contaminated cat will quickly re-fail if oil consumption is unaddressed). Check VIN eligibility against Subaru service program WVI-19 (10yr/100k extended cat warranty) and the Yaeger oil-consumption settlement before paying out of pocket. If the catalyst is genuinely degraded, replace with a CARB-compliant OEM or direct-fit converter and a new rear O2 sensor.

On the 2009-2018 Subaru Forester, foresters commonly throw front oxygen/air-fuel-ratio sensor heater-circuit codes (P0031 low, P0037 downstream) as the sensors age. The sensors live on the hot exhaust, so the wiring harness near them turns brittle and chafes, and the internal heater element degrades. The result is an illuminated check-engine light, slightly richer/leaner running while the heater is cold, and a guaranteed emissions-test failure. Many owners replace the sensor only to find the real fault is damaged harness wiring at the connector.
Common Symptoms
Check-engine light with P0031 or P0037
Failed emissions/smog test
Slightly reduced fuel economy
Occasional rough cold running
No drivability change in some cases (code only)
How to Fix
Scan and confirm the exact code, then inspect the sensor connector and pigtail for melted, chafed or broken wires before condemning the sensor — repair the harness if damaged. If the heater element itself is open, replace the front air/fuel ratio sensor with the OEM-spec part (Subaru sources Denso/NTK); aftermarket universal sensors often re-trigger the code. Clear codes and verify heater operation.

On the 2014-2018 Subaru Forester, the forward (front) bushing in the front lower control arms wears out prematurely on 4th-gen (SJ) Foresters, often by 40,000-70,000 miles on normally-driven, paved-road vehicles. As the bushing degrades it allows the control arm to shift, producing a rattle/clunk, a vibration or shudder felt through the steering wheel (especially on highway turns or undulations), uneven outer-edge tire wear, and a vague, unstable steering feel. Subaru acknowledged the design issue in TSB 05-63-18 and revised the production bushing. This is distinct from the rear suspension bushing clunk and is frequently misdiagnosed as a worn steering rack.
Common Symptoms
Clunk / rattle from front suspension over bumps
Vibration or shudder in steering wheel at highway speed
Wandering, unstable, or vague steering
Uneven outer-edge front tire wear
Knocking felt when turning
How to Fix
Per TSB 05-63-18, replace the front lower control arm forward bushings (or the complete control arms) with the updated parts, then perform a four-wheel alignment. Independent shops typically replace both control arms as assemblies; budget roughly $400-700 per side in parts and labor, or about $900-1,400 for the pair plus alignment.

On the 2014-2018 Subaru Forester, in regions with heavy road-salt exposure, the steering rack/pinion (EPS) gearbox housing on 4th-gen Foresters can corrode to the point a crack forms in the gearbox body. This produces uneven or notchy steering effort and, in advanced cases, a knock or play in the rack. Subaru documented the concern in TSB 04-21-18 (July 2018) and issued an Electronic Power Steering gearbox warranty extension for 2012-2018 vehicles. Occurrences are concentrated in the rust belt and are described as limited, but the repair is expensive when out of coverage.
Common Symptoms
Uneven or notchy steering effort
Clunk or play in the steering rack
Visible corrosion on the steering gearbox housing
Steering feels heavier in one direction
How to Fix
Subaru extended the warranty on the EPS gearbox assembly for affected 2012-2018 vehicles — owners in salt regions should check VIN-specific coverage and have a dealer inspect for housing corrosion/cracks. The remedy is replacement of the steering gearbox (rack) assembly. Out of coverage, a complete electric rack replacement plus alignment typically runs $1,200-2,200.
On the 2014-2020 Subaru Forester FB25, foresters with the 2.5L FB25 engine experience premature A/C compressor failures, often with a noisy clutch or complete seizure. The compressor clutch bearing fails first, creating a grinding or squealing noise when the A/C is engaged. If not addressed, the compressor can seize and send metal debris through the entire A/C system, requiring replacement of the condenser, receiver/drier, and expansion valve in addition to the compressor. The issue is common between 60,000-120,000 miles.
Common Symptoms
Grinding or squealing noise when A/C is turned on
A/C blowing warm air intermittently
A/C clutch clicking on and off rapidly
Complete loss of cold air from vents
Burning rubber smell from engine bay when A/C is on
How to Fix
Replace A/C compressor assembly (Denso 471-6050 or Subaru OEM 73111SG010). If compressor seized and sent debris, flush the entire system and replace condenser, receiver/drier (Subaru 73520FJ001), and expansion valve. Use PAG 46 oil and charge with R-134a to factory spec (15.5 oz). A/C clutch relay and pressure switch should be tested before assuming compressor failure.

On the 2009-2021 Subaru Forester, foresters are prone to early front brake rotor distortion (thickness variation) that produces a pronounced pulsation/judder felt through the steering wheel and brake pedal when braking, often appearing at relatively low mileage. Owners across multiple generations report warped/judder-prone front rotors, and machining or same-part replacement frequently doesn't last. Subaru has acknowledged brake judder across its lineup with a revised front brake pad material via TSB (e.g. 06-91-24R on related Legacy/Outback/Ascent platforms). A caliper piston or seized slide pin not fully retracting (dragging pad) accelerates the heat cycling that distorts the rotor.
Common Symptoms
Steering wheel and pedal vibration/shudder when braking, especially above 40 mph
Pulsation that returns a few thousand miles after rotors are resurfaced or replaced
Uneven rotor thickness / visible scoring at inspection
Brake judder reappearing prematurely under normal driving
How to Fix
Replace front rotors and pads — ideally with updated-material brake hardware rather than resurfacing the original rotors. Inspect and service the front calipers and slide pins so a dragging piston/pin isn't re-warping the new rotors; use proper torque and an even bed-in procedure.
