2020 Subaru Forester Problems

As I was driving my 2020 Subaru Forester a cracked suddenly appeared across the driver side of the windshield, possibly from a small pebble. The sunlight reflection off the crack sent blinding sunlight into my eyes which nearly caused a collision with the car stopped in front of me. I now have another crack that started from the other side making my car unsafe to drive. Both cracks continue to grow across the windshield, not sure if summertime temps make it worse. I spoke with the dealer and they have quoted thousands of dollars to replace the windshield and since the car has over 100,000 miles they won't replace it under the new warranty that was extended this year. This is my 3rd windshield and can't afford to keep replacing windshields and now I don't have a car to drive. See attached pictures of the windshield.

The contact owns a 2020 Subaru Forester. The contact stated while driving approximately 40 MPH, the contact became aware of a 7-inch crack at the bottom of the windshield near the driver’s side pillar running horizontally. The contact stated that there was no impact on the windshield to cause the crack. The vehicle had not been taken to a local dealer or independent mechanic to be inspected. The vehicle was not diagnosed and was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 45,000.

Smoke and fire occurred in the engine and spread into the car while the car was being driven. The car has not been inspected yet.

24th February 2020 - Bought the car from Subaru dealer. Couple of service records prior to May 24, 2022. - May 24, 2022 (9,037 miles) | RO# 806326: The lower oil pan leaked prematurely and had to be completely replaced under warranty. During the same visit, explained LONG BRAKE PEDAL issue, and was given an estimate. - - June 1, 2022 (9,039 miles) | RO# 806767: Just 2 miles after that repair, the oil pan had to be torn apart again because the internal oil level sensor failed and got stuck. - January 19, 2024 (18,854 miles) | RO# 838995: The vehicle suffered a dangerous engine shutdown in the middle of traffic due to the factory Thermo Control Valve defect (TSB 09-80-21). While resolving this safety defect under warranty, the dealer used scare tactics to upsell me $794.23 out of pocket for unrelated maintenance. - July 3rd, 2025 - You can see from invoice records that indicate, customer requesting a quote on repairing the windshield chips, as I learned on 26th August 2026 (during call with Subaru corporate) that it was under extended warranty, dealership offered me a quote and did not volunteer to repair at no cost nor conveyed information on extended warranty. This damage happened twice due to poor quality of Windshield in my car. - 23rd August, 2026 - This 2020 Subaru Forester has experienced repeated failures involving the Auto Start/Stop system. When stopped in traffic, the system shuts the engine off as designed, but on multiple occasions the engine has failed to restart normally when the driver needed to proceed. This has left the vehicle unable to move in active traffic and created a serious risk of collision. The failures have occurred in highly dangerous situations. - 24th August, 2026 - Similar incident happened the next day. - 25th August 2026 (39,000 miles) | Present Day: The lower oil pan seal has failed yet again. Dealership is suggesting a battery replacement. Shared inspection video shows, rusts on bolts, very unusual for a car driven only 39000.

Smoke and fire occurred in the engine and spread into the car while the car was being driven. The car has not been inspected yet.

Three times within 30 minutes on short drive, the engine stalled at stop sign or stop light. The car had a half tank of gas, and at the same time as the engine stalled, the miles remaining until empty display showed an anomalous 0.3miles to empty reading. Put the car in park allowed the engine to restart and the range remaining display to return to normal.

**Component or System:** Subaru EyeSight Driver Assist System (specifically the Pre-Collision Throttle Management system). **Incident Description & Warning Messages:** There were no warning lamps, messages, or symptoms of any problem prior to this failure. The incident occurred while I was stopped at a red light at a busy intersection. When the light turned green, I removed my foot from the brake and pressed the gas pedal to proceed, but the vehicle would not accelerate. The system had engaged a false-positive throttle cut. At that exact moment, the car began beeping repeatedly and the EyeSight logo flashed on the dashboard, incorrectly indicating an obstacle or imminent collision, even though the path in front of my vehicle was completely clear. **Safety Risk:** My safety and the safety of others were put at significant risk because the vehicle was unexpectedly immobilized in an active intersection during a green light. This sudden, unwarranted loss of acceleration created a high risk of being rear-ended by the drivers behind me who were expecting the flow of traffic to resume. **Reproduced, Confirmed, or Inspected:** Because this incident just occurred, the problem has not yet been reproduced or confirmed by a dealer or independent service center. Furthermore, the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives.

While driving on public roads, all dash warning lights illuminated simultaneously. The instrument cluster displayed “EyeSight OFF.” At the same time, the electronic parking brake engaged / the vehicle would not accelerate and required me to stop and shift to Park. The only way to restore drivability was to turn the vehicle off and restart. This has occurred intermittently, including in traffic, creating a serious safety hazard for myself and surrounding drivers.

Component/System Defect: Failed Thermo Control Valve (TCV) leading to sudden vehicle power loss / limp mode. Description of Safety Incident: While operating my vehicle at highway speeds late at night, the Thermo Control Valve (TCV) failed catastrophically without warning. The vehicle instantly experienced a massive loss of engine power and entered an aggressive "limp mode," causing a drastic, uncommanded deceleration in active traffic lanes.Due to the sudden reduction in speed and the low-visibility night conditions, a commercial semi-truck traveling directly behind my vehicle was nearly unable to brake in time and narrowly avoided rear-ending us. My family—including an elderly senior and a [XXX] child—was trapped inside the vehicle during this near-miss collision. The vehicle became an immediate hazard on a high-speed highway. The authorized dealership subsequently confirmed a failed Thermo Control Valve (TCV) and replaced the unit under Subaru's extended warranty program.

This 2020 Subaru Forester has experienced repeated failures involving the Auto Start/Stop system. When stopped in traffic, the system shuts the engine off as designed, but on multiple occasions the engine has failed to restart normally when the driver needed to proceed. This has left the vehicle unable to move in active traffic and created a serious risk of collision. The failures have occurred in highly dangerous situations, including a busy [XXX], a major [XXX] intersection, and most recently while entering a freeway. In these incidents, surrounding drivers had to brake hard to avoid striking the disabled vehicle. The occupants reasonably feared a serious collision, and the events were potentially life-threatening. The battery was replaced, but the Auto Start/Stop no-restart condition later occurred again, so battery replacement did not resolve the problem. Subaru issued Technical Service Bulletin 16-147-24 on XXX for 2019-2021 Foresters. The bulletin addresses TCM reprogramming related to engine behavior during Auto Start/Stop restart and instructs technicians to reprogram the TCM when the described symptom is reported. However, the bulletin’s warranty section provides reimbursement under the Basic New Car Limited Warranty. For a 2020 vehicle, the original 3-year/36,000-mile basic warranty would ordinarily have expired before this 2024 bulletin was issued. The vehicle is now being evaluated by an authorized Subaru dealer. The condition is intermittent and dangerous because the driver cannot know whether the engine will restart when movement is required. The vehicle is available for inspection.

Automated lift gate opened fully, and then immediately closed without warning upon a person who was trying to access the back, nearly causing injury. It is unknown what precisely is failing within the lift gate and it is available for review. The automated lift gate can close on a person unexpectedly potentially causing injury. This has been reproduced as was "fixed" by the dealer but then reappeared only a month later with the same issue. The vehicle was not inspected by anyone but the dealer's service representatives. There was a soft beep emitted as it came down but the behavior was completely unexpected. There were no warning lamps or other information as to something was non-functional, only the soft beep as the lift-gate fully opened, then automatically fully shut right after.

The contact owns a 2020 Subaru Forester. The contact stated that while driving at 60 MPH, the hood was independently unlatched and opened. The light indicating that the hood was opened illuminated. The contact stated that he pulled to the shoulder of the road and closed the hood. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 36,000.

stalling/shutting down at stoplights with the auto start-stop feature has occurred continuously for the last 2 years I’ve taken to dealer, and multiple mechanics and they can’t find a problem

Eyesight pre-collision braking feature and pre-collision throttle management feature malfunctioned and caused the 2020 Forester to accelerate unexpectedly and lurch forward while I was manually braking and slowing to come to a complete stop behind two other vehicles stopped at a steady red light. See class action lawsuit Weston, et al. v. Subaru of America, Inc., et al. In US District Court Case No. [XXX] which alleges that the vehicle contains certain defects that caused sudden and unintended acceleration without driver input; acceleration while manually braking; and that these defects created a safety risk, because they severely affected the driver's ability to control the car's speed, acceleration, and deceleration, and increase the risk of a collision, which did in fact occur. The defective car was completely totaled and towed to a salvage yard by the police and the insurance company. Defect malfunction caused a collision which resulted in property damage and personal injury to three vehicles and three people. I mentioned the defect to my insurance company at the time of the accident. I do not know if they chose to follow up and inspect the vehicle. The problem occurred twice before ( not resulting in property damage or injury) and I took it to my Subaru dealer both times and they claim that they could not find anything wrong, but oddly did not note that they checked for the problem which I brought to their attention on the written summary/invoice for my service visit. See the class action lawsuit- this is apparently the typical dealer non-response to the problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my girfriend's 2020 Subaru Forester on August 11, 2026 at approximately 65 to 70 mph, I struck a deer on a highway. The airbags deployed immediately, and I temporarily lost all forward visibility due to the airbag deploy, and smoke or steam coming from the front of the vehicle as it decelerated to a stop. Within moments of stopping, smoke transitioned to visible flames coming from the engine compartment. The fire spread extremely quickly, and the vehicle became fully engulfed in flames within minutes. The specific component or system that failed is UNKNOWN, but based on the sequence of events, it appears that a front‑end structural failure during the collision may have caused a rupture of one or more engine‑bay components (oil system, coolant system, or other fluid lines), leading to a rapid fire. The vehicle was completely destroyed and is not available for inspection, but the incident was documented by emergency responders and my insurance company. This fire created a severe safety risk, as the vehicle ignited shortly after coming to rest and burned intensely. I had no warning lights, messages, or symptoms prior to the collision. The problem has not been reproduced, but I have since learned of multiple similar fires involving Subaru Foresters after front‑end animal impacts, which raises concern about a potential design vulnerability.

The airbag system has a sensor issue and I keep getting warnings from Subaru to get it fixed because it affects the seatbelts. The garage where I take my car says they are unable to get the part needed for the passenger sensor. And, Subaru says they need to replace the whole harness for $6000. Makes me wonder why a safety issue like this one seen in other Subaru’s have been recalled but not my model… Also the start stop feature drains the battery excessively. I have had to replace the battery twice in less than a year. I push the button to stop this feature the minute I get into the car.

The passenger seat airbag sensor does not activate all the time. My girlfriend weighs [XXX]. When she sits in the passenger seat, it only activates the sensor approx 50% of the time. I took it to Subaru, they indicated the sensor was working properly, and their resolution to the issue was for her to weight at least 120 pounds !!! I have that in writing on the repair ticket from Dreyer Reinbold Subaru Greenwood Indiana. I took my complaint to Subaru, and after repeated follow up phone calls, I was informed that in Subaru's owners manual, it stipulates that the individual must meet certain criteria in order to activate the passenger seat sensor. I have yet to find that reference. So, does Subaru inform every potential buyer of the fact that individuals seated in the passenger seat must meet the 120 pound minimum weight to activate the airbag sensor to keep them safe ? I bet not. Thank you for your consideration to helping me keep any passenger in my 2020 Subaru safe, and for countless others that may have have this issue but never check to insure the airbag becomes activated. I have seen recalls for 2020 Outback & Legacy for the same issue with the passenger seat sensor, is it possible some Foresters have the same sensor?

I was on cruise control, and it randomly decided to go 81 MPH instead of 50 mph i set it to, it did not respond when I tried to turn off the cruise control, and I ended up crashing into a semi, I survived but my [XXX] daughter died.

My Forester just totally shuts down sometimes from the auto start feature in traffic or intersections . Errors come up . The wheel locks and I must put the car in park , turn it off and turn it back on. Very scary and very dangerous.

The automatic rear liftgate opens all the way, then closes automatically on your head/back. This has been happening with my car for over a year. When it started, it was occasional, but now it happens nearly every time. When it closes, it does so with considerable force, and has knocked me over twice. One time it hit my head just right and I came close to losing consciousness. I have taken it to Subaru and they said it wasn't an issue. They just reset the liftgate trim height, but that only fixed it for 2 closes. Then it started again. There are many reports of this issue online, and others note that it is a safety concern as well. Others have reported that replacing the liftgate struts and/or the entire liftgate mechanism resolved the problem.

I bought a 2020 Subaru in March of 2020. I had reported an issue with the seat to the dealer Orange Coast Subaru and they had failed to diagnose or repair the issue. The issue was brought up to them several times and they only came to the car and looked quickly at the seat and told me it is fine without any in debt diagnostics. Looking and sitting in a seat wasn't in any shape or form diagnostics of the seat. Nobody looked under the seat or did a inspection beyond just looking and seating on it. Over the years the seat became woobly, unstable, it has cracked. I went for another issue to another dealer this time, Timmons of Long Beach, and paid a diagnostics fee to be told the frame needs to be replaced and it is a safety issue and has to be done asap. I had reached out to Subaru who advised the car is out of warranty. I pointed back to that the issue was reported to them and they said if it was not diagnosed as a failure then then it is unrelated to the issue found now. The seat is unsafe and it can result to injuries to myself and my son. Subaru doesn't want to take responsibility for it. The car has never been in an accident.

Since I purchased my Subaru Forester new in 2020, people regularly flash their high beams at me at night when my low beams are on, because they think I have my high beams on. I also flash my high beams at cars when I think they have their high beams on then they do the same, to show me they have their low beams on. It needs to be illegal for manufacturers of cars and/or headlights to manufacture low beams with these dangerous settings. I didn’t know I could file a complaint with this department until a week ago otherwise I would have done it in 2020

LED ADAPTIVE HEADLIGHTS BLIND ONCOMING DRIVERS. I HAVE MANY DRIVERS FLASHING THEIR HIGH BEAMS AT ME WHEN DRIVING ON LOW BEAM SETTING WITH FOG LIGHTS OFF. NEW CARS WITH LED HEADLIGHTS UNLESS ON FLAT ROADS CAUSE TEMPORARY BLINDNESS IN PEOPLE WITH SENSITIVE EYES DURING HOURS OF DARKNESS. ANYTIME THESE VEHICLES ARE ON A GRADE, THE BEAM AND COLOR OF THE LIGHT IS VERY INTENSE. WHEN THESE LIGHTS ARE NOT ADJUSTED CORRECTLY, SAY AFTER SOMEONE ALTERS A VEHICLE (LIFT, LOWER,ETC) THEY ARE ABSOLUTELY BLINDING. I KNOW THERE ARE MANY STUDIES THAT SHOW THE WHITER/BLUE COLOR ON THE SPECTRUM, THAT HUMAN EYES ARE NOT MEANT TO ADAPT. EXAMPLE, BLUE LCD DISPLAYS ON APPLIANCES ARE MORE DIFFICULT TO SEE THAN RED OR GREEN. YES THE LIGHTS ON MY WIFE'S SUBARU MAKES IT EASIER TO SEE FOR US, HOWEVER IT IS BAD FOR EVERYONE ELSE. IT IS ALSO DIFFICULT TO SEE DIRECTIONAL SIGNALS IN THE HEADLAMP HOUSING WHEN THE HEADLIGHTS ARE ON. I KNOW THIS WILL NOT LIKELY CHANGE ANYTHING, I'M AFRAID THESE LIGHTS WILL CAUSE IMPAIRED OR FATIGUED DRIVERS A BETTER CHANCE OF BEING INVOLVED IN HEAD ON CRASHES WITH THE VEHICLE WITH BRIGHTER LIGHTS. THIS IS A STUDY THAT SHOULD BE INVESTED, SUCH AS WAS DONE WITH EMERGENCY VEHICLES LIGHTS.

I have had to replace the tire valve stems on ALL 4 tires. In addition, 1 of the replacement valve stems also had to replaced within 1 year when it was first replaced. All this within the first 3 years of owning the vehicle.

February 2020 both rear and front driver side tires (manufacturer provided) ripped potentially after hitting pothole. Dealership replaced 2 tires. November 2020 tire started a slow leak (in 5-7 days)- dealership fixed per manufacturer recommendations, leak continued at a lower pace (in 3-4 weeks)

My one year old is able to press the chest clip and it unlatches. So now the only thing holding him is the buckle. He has been able to undo the chest clip. While driving in traffic. This should not happen. Could be terrible danger if got in a car accident.

VEHICLE VIBRATE STARTING AT 50 MPH AND GETS EXCESSIVE AT 65MPH AND UP, WHILE CRUISING IN THE HIGHWAY. THE VIBRATION CAN BE FELT ON THE STEERING WHEEL AND THE DRIVER SEAT SEAT.
