Top problems in owners’ words

Visibility/wiper
33 reports
“My 2017 Legacy is on it's 3rd windshield this year. I had impact damage on July 17th, had it replaced the first week of August, and it cracked without impact damage in October. Subaru refused to replace it under warranty and it was replaced through insurance in December. The genuine Subaru replacement windshields for 2015-2019 Legacy and Outback models appear to be defective and this should be investigated.”
Electrical system
30 reports1 fire
“Since the battery replacement settlement I've had 3 batteries die from my car being off, the latest battery replacement was 3/2026. I can't tell what my milage is since the battery is so dead that none of the displays turn on when I hit the start button”
Steering
9 reports1 crash2 related recalls
“Purchased the car used took to dealership for rattle from front end, they diagnosed and recommended replacement of steering rack as it was defective, so it was replaced, a month later same noise, same diagnosis, replaced again, repeated this 7 times and they have reconfirmed it is the rack, the dealership technician states it’s the rack and not as it should be. The manager however is trying to state now that it’s a normal noise and they won’t warranty the repairs anymore. It continues to get worse and louder and feels unsafe to have defective steering racks on the roadways that are non repairable. I’ve reached out to corporate Subaru as well and they can only make decisions based off info the manager gives them which is opposite of what the technicians state. Please help me this car is unsafe.”
Air bags
7 reports6 crashes
“The OCS sensor is faulty and doesn’t detect a passanger and may cause the airbag not to deploy, this is common according to other Subaru owners. This is a common problem on many cars and those cars have been recalled”
Structure
6 reports
“Hood released and blew open while doing 50 mph. After checking oil level, I closed and verified hood was latched, which it was. Driving about 2miles down road, hood blew up causing instant panic and stopping. After pulling over, I found that the hood would no longer latch. I had to use a hammer to bend the latch forward enough to have it latch again.”
Service brakes
5 reports1 crash
“I drove into the parking lot of Walgreens, then drove around and pulled into a parking spot facing the south side of the building and put my foot on the brake to stop and park. Instead of stopping, the car suddenly lurched forward violently and slammed into the brick wall of the building. My wife called 911 since I told her my chest really hurt. When the police came, I told them my foot must have slipped off the brake and hit the accelerator, since I had no idea what else might have caused the car to accelerate like that. My wife drove the car home and then drove to the ER where the EMTs had taken me. A CT scan showed that I had a fractured sternum, since my chest hit the steering wheel full force after the air bags failed to deploy. I was in excruciating pain for a few weeks, and after I felt better, we submitted a claim to our insurance company. We then took our 2017 Subaru Legacy to a certified Subaru collision repair center. We were shocked to find that the car was totaled, since it was still drivable. Something kept bothering us about the crash, since EyeSight should have applied the brakes if I had accidentally accelerated and it detected a brick wall in…”
