Recalls and investigations

One recall on the windshield and wipers covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.

18V-935Dec 31, 2018
Visibility:Rearview Mirrors/Devices

Subaru of America, Inc. (Subaru) is recalling certain 2018 Legacy, Outback, and BRZ vehicles. In the affected vehicles, a software issue may cause the audio display system to not initialize, resulting in the camera display remaining blank. If this occurs, the rearview image will not display while backing up the vehicle. As a result, the vehicles fail to comply with requirements of Federal Motor Vehicle Safety (FMVSS) number 111, "Rearview Mirrors."

Risk and remedy
Risk: Failure to display the rearview image while backing up increases the risk of crash.
Remedy: Subaru has notified owners, and dealers will reprogram the audio system display software, free of charge. The recall began on February 5, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WTZ-85.

What owners wrote

“MAR 2024: 2018 Subaru Legacy, 36,000-miles. (1) Front Windshield had crack in it randomly one day. Coming up from bottom heating element. Easily able to find similar crack shape online. Find lots of windshield crack issues online for Subarus. Zero action from Subaru on this. (2) Broke again 11 months later [FEB 2025] in similar fashion, randomly one day.”

“I have had the windshield replaced in this vehicle three times in less than one year. I recently took my car through a car wash that I use regularly and the next day, there was a new crack on the lower passenger side of the windshield. This is getting expensive to fix and seems to be a defect with the windshield.”

Should you keep driving it?

This page can't tell you that. 0 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
