Engine has rod knock present common amongst owners. Short block replaced under warranty at 55k miles. How can a stock engine with synthetic oil changes commonly fail? Flaws.
The secondary o2 pump will burn out or continue running causing unsafe risk to short circuit a fire. Recall has already been previously documented in the -2014 models however Subaru uses the same design and part number. My car Secondary o2 Pump was replaced under warrenty at 55k miles now at 90knmiles have the same CEL code.
I first noticed the car engine began making a loud ticking sound and significantly lost power as I exited the freeway heading toward my home after work. After towing the vehicle to the Subaru dealership, they tore apart the engine and found a connecting rod bearing had failed. It had slid out between the rod and crankshaft and shattered in the oil system sending shards of metal into the engine and all components that the oil touches. Every component that oil touches needed to be replaced. Prior to this problem, maintenance and oil changes were performed according to Subaru's specifications. Had the engine completely failed on the freeway during my commute home (during rush hour traffic) I could have caused an accident and possibly hurt myself and others. Subaru inspected and kept the components that were faulty though they never accepted responsibility for the failure of the components. There was absolutely no indication nor warning signal prior to the failure of the connecting rod bearing. Subaru blamed me for the component failure saying the vehicle was not properly maintained though they never asked me for proof of maintenance. I had to pay $7868 to repair the car to it's original mechanical state.

Turbocharger intake cracked and causes the engine to have an extremely rough idle and stall. My vehicle has the same issue as the federal safety agency campaign number 16V16200 however it was manufactured before April 10th 2015 so it is not included in that recall.
Car battery is constantly drained even when car is used every other day
DEFECTIVE OEM THROW-OUT BEARING and FORK in the SIX SPEED manual transmission completely BURNING the clutch. I was going up a hill and the car just started rolling back. No gear would work on the car.
