The catalytic converter has been replaced twice and is now needing a third replacement. The car emits gas fumes, unsafe emissions, and the fuel causes the mechanism to be extremely hot and unsafe. Over time, the car has had reduced gas flow and will stop running. The dealer has confirmed the three converters installed have been defective. The manufacturer, Subaru, was contacted to inspect the car but refused. Precious years have recalls of the fuel mechanisms. The check engine light stays on when unsafe emissions are detected.

When running on a highway and you press down on the accelerator hard to merge onto a highway or go around a vehicle to move out of the way of vehicles quickly coming up behind you, the engine takes over and speeds up on its own. It has occurred three times on a newly purchased used car and it will increase speed up to 100mph. You have to press intermittently on the brakes to pull over to the shoulder and turn off the car for five minutes for the car to reset. If you try to just break, you get a burning smell. I see two class action lawsuits on similar acceleration issues for 2015 to 2017 Outback/Legacy series.

The contact owns a 2017 Subaru Legacy. While depressing the brake pedal and coming to a complete stop, the engine shut off without warning. The contact was able to restart the vehicle and it operated normally; however, the failure later occurred several times. The dealer performed diagnostic and fuel testing, which produced a code of P1603 and a good fuel reading; however, the contact was advised to use a different fuel station. The manufacturer was made aware of the failure. The failure mileage was approximately 800.
