2020 SUBARU LEGACY Complaints

Sunroof exploded spontaneously while traveling down freeway. No one was within 3/4 of a mile in all directions.

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 [XXX] ) 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. I want to upload the Subaru dealership paperwork I received when I picked up the car, but the upload function is not working. Please send me an email if you would like a copy.

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 [XXX] 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 INFORM

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

While driving on freeway the tire pressure warning light came on. I started to slow down and pull over and I felt the car wobble. I pulled to the side of the road and the tire had completely failed. The sidewalls, inside and out, had square chunks completely gone along the complete sidewall.

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. The problem occurred without any prior warnings or messages. I am told by the dealership (Bob Moore Subaru of Oklahoma City) that it is part #61041AN00A that requires replacement.

Thermo Control Valve failed. Caused a short which affected all electrical components on its circuit. The car became inoperable in traffic.

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.

Thermo Control Valve has malfunctioned. It disables all driver assistance, like lane assist, blind spot, RAB, collision braking, etc. I have seen on many forums that this is a known issue, across multiple vehicles from Subaru from 2019 to about 2021. The was a TSB put out about a new and improved part to fix this known issue.
