Visibility/wiper

57 reports
“I have had two spontaneous window cracks within 6 to 9 months apart. I had a full windshield replacement and the windshield has just cracked again. The second incident, the vehicle was parked overnight so it wasn't caused by a rock or from following a car.”

Electrical system

15 reports1 fire
“While driving there is a loss of power, the battery fails, electronic components shut down and car stops. Has happened intermittently. Replaced battery. This is a significant safety issue happened on freeway near exit ramp, in parking lot in driveway, everything cuts out. Opened hood and seems to be battery terminal connector. Recall was issued for certain Subaru models but not legacy. No warning, just cuts off. Is not a standard battery terminal connector. Had to secure battery down with cable ties.”

Visibility

9 reports
“The contact owns a 2020 Subaru Legacy. The contact stated that during inclement weather, the front driver and front passenger’s side power windows failed to automatically roll up as intended. The contact was forced to hold the power window button to slowly roll the windows up. The vehicle was taken to a dealer, where the contact was informed that there was debris in the slides inside the windows, causing the windows to fail to retract. The contact stated that the driver’s side window retractor was replaced; however, the failure returned soon after the repair. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was 29,000.”
