Air bags: front passenger

24V227000118,723 vehicles affected

The problem
Subaru of America, Inc. (Subaru) is recalling certain 2020-2022 Outback and Legacy vehicles. A capacitor in the sensors for the Occupant Detection System (ODS) may crack and short circuit, which can prevent the front passenger air bag from deploying in a crash.
The risk
An air bag that does not deploy during a crash can increase the risk of injury.
The fix
Dealers will replace the ODS sensors on the front passenger seat, free of charge. Owner notifications were mailed February 3, 2025. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRA-24.

20V7660007,741 vehicles affected

The problem
Subaru of America, Inc. (Subaru) is recalling certain 2020 Legacy and Outback vehicles equipped with "high" grade and "mid" grade multimedia navigation. The August 2020 over-the-air software update may have timed out without completing the installation, corrupting the data, and causing the rearview display to shutoff intermittently. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
The risk
The intermittent loss of the rearview image reduces the driver's visibility and increases the risk of crash.
The fix

The risk
A missing or loose bolt may cause the brake pedal mounting area to deform over time, which can reduce braking performance and increase the risk of a crash.
The fix
Subaru will notify owners, and dealers will inspect the brake pedal mounting bracket hardware and replace the hardware or brake pedal assembly, as necessary, free of charge. The recall began October 1, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUL-97.

The contact owns a 2020 Subaru Legacy. The contact stated that during inclement weather, the front driver and front passenger's side power windows failed to automatically roll up as intended. The contact was forced to hold the power window button to slowly roll the windows up. The vehicle was taken to a dealer, where the contact was informed that there was debris in the slides inside the windows, causing the windows to fail to retract. The contact stated that the driver's side window retractor was replaced; however, the failure returned soon after the repair. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was 29,000.

One hour into traveling on the highway smoke began to come from under the hood so we pulled off to the side of the road. Upon opening the hood, after the smoke cleared, a fire was observed. At that point the passengers exited the vehicle and called 911. There was no warning lights or sounds indicating any problems prior to this. The car burned very quickly and the firefighters extinguished the fire but not before the entire car was burned to ashes. The car is wrapped and in the possession of the insurance company pending investigation.

in inclement weather the windows will not roll up, especially heavy rain events. The window will attempt to go up and then go into the fully open position. You have to wait a minute before the window will allow you to attempt again of reset the windows. This happen to me on the highway in a heavy rain. It has happened several times. Subaru knows of this problem and has a technical bulletin about it to change the motor and window tracks. They all should be changed before a fatality occurs

The engine thermo control valve has been defective and Subaru has known this issue since 2022 and has tried to do some software update but it is defective [[redacted]] ) despite multiple tries. This can overheat an engine, result in the front collision warning system (eyesight) and rear auto-braking not working. Specific to my case, the front and rear collision warning systems are off, auto lane departure avoidance system is off, the engine can overheat and has had reduced performance, and the check engine lights are also on.

The coolant bypass valve was defective. You would have to ask the dealership to inspect it, they kept it when they changed it out. It is unsafe because the engine could have overheated and exploded. The problem has been confirmed Subaru of Little Rock. They replaced the valve and some other parts. The check engine light came on when I started the car the night of Dec 22, 2023. At this time, the heat was struggling, the vents were barely blowing, and the thermometer would only work sometimes.

We recently purchased a used 2020 Subaru Legacy sedan with ~33,000 miles on it. It has a salvage title due to previous owner hitting a deer, (no air bag deployed, just minor body work) and it was professionally repaired to "like-new" condition. Last weekend, when starting the car, the check engine light and a bunch of other warning lights came on. An OBDI scan showed a code of "P263A" indicating a problem with the Thermo Control Valve. As a result of the defective TCV, several major functions of the vehicle...

were automatically disabled: adaptive cruise control, eyesight system with lane keeping, automatic braking, as well as all cabin heating, windshield defrost function, and the engine temperature gauge. Without these systems properly working, the drivability of the vehicle is greatly impaired, especially in a Minnesota winter without a functional windshield defrost and engine temperature monitoring gauge. When taking the car into the local Subaru dealership for full diagnostics, they confirmed that indeed the TCV was bad, and quoted me a cost of $1135 to replace it. They claimed that since the car has a salvage title, Subaru's warranty will not cover any part of this repair. However, there is a known wide-spread failure of this Thermo Control Valve in the 2019-2021 cars as listed in Subaru Technical Bulletin [[redacted]] which clearly states that there is a redesigned TCV that replaces the defective earlier part and fixes the earlier design flaws of the one installed in 2019-2021 vehicles. I spoke with the Subaru of America Client Advocacy representative, and he was adamant that the salvage title negates any responsibility for Subaru to fix this know defectively designed Thermo Control Valve. My thinking is that the defective TCV is both a drivability and a safety issue, and due to the wide-spread early life failure of this part, Subaru should be compelled by a recall to replace the defective car in all customer cars. All ADAS is affected by a bad TCV. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Transmission & drivetrain

At approximately 30k miles we had noticed the vehicle sounded loud, like a Turbo. It got worse and after returning from our vacation trip to Maine, it was noticeable louder but couldn't place a finger on the problem. We brought the vehicle in to Victory Subaru in Morristown and they diagnosed the two rear failed wheel bearings. My question is how can both wheel bearings fail at only 20k and is there a potential for a system wide recall? Thanks

The front door window regulator of our 2020 Subaru Legacy is not working properly. It fails to raise and lower correctly and reliably which can be a safety issue especially in an emergency.

This past Sunday evening, I drove to the convenience store 4 blocks away. As I returned, I noticed a crack in the windshield starting in the middle from the left edge and was about 12 inches long. No gravel marks were found, it had cracked for no apparent reason. Sitting the next night in the garage, the crack increased about 6 more inches by the next morning. Filed claim with my insurance and was subsequently replaced by Safelite here in Knoxville Tn. This cost me $100 out of pocket and no telling how much my insurance had paid. I just found the class action today.

Windshield spontaneously cracked at top. I came outside in the morning after a temperature fluctuation and there was a crack at the top with one piece of the glass sitting lower... it has since grown. I have been forced to drive with the crack as Subaru will do anything to not honor a warranty, ever. The eyesight I am learning is necessary for the vehicle to avoid front end collisions and to properly deploy the airbag.

warranty I paid. I see many people have the same problem. You can even see where the windshield cracked where an iPass was mounted from a temperature change. The wipers also cannot keep up with moderate rain, causing rain blindness in moderate precipitation and the lightest rain will turn off the eyesight causing a malfunction that will not assist in avoiding a collision. In addition, I will be complaining with the CFTC for the warranty issues. I cannot even get records of my warranty or service. Example: window regulator was a problem off the log, and salesman used it as an example, service won't repair. I regret buying a Subaru, they claim to be safe and reliable with great service, I am only having problems that affect the safe operation of the vehicle and I paid all this extra for full bumper to bumper and they tell me that it doesn't exist. In addition, that vehicle claims to get close to 30mpg, I am being completely honest when I say I had about the same mileage in a 1995 Cadillac Deville, and the mileage I got in a 2009 BMW twin-turbo far exceeded the mpg. I tried to get it repaired today under warranty. I was yelled at that it was an impact, and I wish I knew... would have said, "is it more likely that I'm lying or the company that's been successfully sued 4 times for this exact problem is at fault?" Perhaps there was a light impact in the months AFTER it broke parked in a unheated garage.
