What owners wrote
“While driving my Subaru Outback, I encounter a problem where the Starlink Multimedia system abruptly goes black. Shortly after, the driver information center also goes black. Although the car continues to run, the cruise control, if engaged, and the EyeSight safety system shuts off as well. Both systems then undergo a reboot.”

“Car has twice stalled out when driving slowly in hot weather. When trying to restart vehicle the engine turned over just fine, but wouldnât restart until much later after the car had a chance to cool down completely. Possible vapor lock or faulty fuel pump.”

Should you keep driving it?
This page can't tell you that. 0 of 44 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.
