“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.”
“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”
“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.”
