5 Engine And Engine Cooling problem

Failure Date: 10/05/2021

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.

8 Engine And Engine Cooling problem

Failure Date: 02/10/2021

I own a 2015 wrx limited cvt. When I go to my car to go to work and I start it, the car sputters. I've only noticed this on cold starts only, once the car is warmed up it's fine. For some reason though when the car is sputtering on start ups it will trip my cel and basically put the car into �get home� mode, but it only seems to trigger the cel when it wants to. The car will always sputter on start up but sometimes the cel will come on and I can't use the drive modes and sometimes it won't come on. No matter what I do I can't get the car to stop sputtering. I've cleaned pretty much every sensor I could and nothing worked. I scanned the obd2 port and got p0300 for random misfire, which tells me absolutely nothing.

9 Engine And Engine Cooling problem

Failure Date: 04/01/2020

The engine blew up around 75k miles, it had blown a rod barring even though the car had been maintained. The clutch prematurly went out causing me to have to replace everything but the flywheel at under 75k miles. The clockspring is bad in the car affecting the horn and air bags. Having to get that replaced as well. The car is currently at a dealership getting everything resolved other than the clutch as thats already been replaced. My safely and others safely were at risk as if the clutch went out while driving, my horn would not work, my airbag light was on flashing and possibly wouldn't deploy in an accident and the engine blowing up due to a thrown rod barring put me at risk as it was on the freeway this happened. You can get all this info on mileage and what has been replaced. This has cost me thousands upon thousands of dollars to fix in the car when none of it should of happened.

10 Engine And Engine Cooling problem

Failure Date: 10/08/2019

Decided to get my spark plugs replaced, and got a compression test done while that service was done for convenience. Compression came out low on one side of my fa20dit engine. With more research, because the engine is direct injected, there is obvious build up on the intake valves, causing bad air flow. This is not a wear and tear issue.

11 Engine And Engine Cooling problem

Failure Date: 09/02/2019

Vehicle had a brand new short block with approximately 6,000 miles on it, and spun a bearing.
