1 Warnings problem of the 2015 Subaru Legacy

Failure Date: 01/20/2026

I am reporting a sudden unintended deceleration event in my Subaru. The vehicle grinded to a halt without driver input. The car stopped in the left lane of a major highway. We put on our hazards and called the state police for help. They were unable to get to us in time. We were hit from the rear. The car's failure created a stationary hazard that led to a high-speed rear-end collision by a Jeep and truck which caused the car to do a 360-degree spin.

2 Warnings problem of the 2020 Subaru Legacy

Failure Date: 11/01/2022

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. The crack started in November, it’s almost August, and I cannot get it replaced under the 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.

3 Warnings problem of the 2020 Subaru Legacy

Failure Date: 11/30/2021

This vehicle is equipped with the Subaru "eyesight" system which is a number of safety features like automatic cruise control, lane keep assist, and others. About once a week on average while driving the entire system will shut down and the screen will go dark. You lose the radio, bluetooth, navigation, and all the eyesight systems. After about 30 seconds it will reboot and things will come back online but this is a major safety issue because you loose systems that help with safety. The dealership said it's a known software issue and there's nothing they can do until an update is available. I called Subaru USA customer support in September and they said an update would be available by the end of October and nothing was released. I called in early November and they said they were still working on it but had no release date.

6 Warnings problem of the 2020 Subaru Legacy

Failure Date: 04/25/2021

Driving home when I notice what I thought was a big hit the window. Slowed to the light and I notice it was actually a small round crack in my glass so I pull in the walgreens lot to see what could of happen. By the time I parked and opened my door I saw the crack had made its way all the way down my window, so I left the door open to see if I could feel the crack but nothing. I get back in lightly closing my door to head 2more miles to my home and the crack made it's way up half way then across half way. My heart literally melted. Why is this happening. The weather was 70 and there was no impact or trees or any speeding cars to have caused this. Makes no sense.
