What owners wrote

The contact owned a 2009 Subaru Outback. The contact stated that while driving at 50 MPH, the vehicle had failed to accelerate above 60 MPH without warning. The contact soon began to notice heavy white smoke in her rear-view mirror as the smoke quickly spread to the front end of the vehicle. The contact immediately pulled over, grabbed vital items, and exited the vehicle. The contact called 911 as flames quickly engulfed the vehicle, and a deputy who witnessed the fire pulled over to assist the contact.

Reported at 200,000 miles, November 2025 FireInjury

The head gaskets on my vehicle have developed leaks at just over 80,000 miles. This is a frequent (and known) problem with the head gaskets on this vehicle. All subaru-specific mechanics, many owners of this model and even subaru dealership employees have expressed knowledge of high failure rates for this head gasket at approximately 80-100k mile intervals. This is way shorter life than should occur and results in a $2000 or greater cost of repair (in my case, $3200!).
