What owners wrote

“Battery is not holding a charge, causing electrical issues (windows not working properly, locks not functioning) and for the vehicle to fail to start. The battery is brand new and this is still an issue. 45,000 miles on the vehicle, there were no warning lights indicating a bad battery. This has not been confirmed yet by a dealership/mechanic/insurance.”

“The battery of the car keep dying, leaving us stranded in what could possibly be unsafe situations. We have gotten the battery checked out numerous times at the dealership, plus got a battery replacement in October 2020 but it still keeps occurring. This is a 2017 Outback with less than 30,000 miles, so should not be happening.”

Should you keep driving it?

This page can't tell you that. 2 of 336 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.
