Engine knock sound while traveling on highway, pulled off next exit and car shut down. No check engine lights or oil lights indicating an issue. Upon restart knocking sound was louder and had a metal sound to it. I immediately shut the car off and called roadside assistance and had the car towed to local dealer. Upon first review dealer identified it as "internal connecting-rod bearing failure" which caused catastrophic engine damage. Subaru of America denied the repair due to the ECM being modified, stating "our engineers reviewed your file and deemed it to be caused by the ECM modification". I have found numerous cases of the exact issue on the internet, as well as a my dealership telling me there is a tsb for this failure. Soa is providing a "one time good faith repair" but I am responsible to replace the ECM. In my opinion this issue which soa is aware of and acknowledges with a tsb should be a recall - the engine failure at highway speed has potential to cause bodily harm - loss of power, engine seize resulting in an accident. I was lucky to not be involved in any sort of accident. Further I am totally unsure of how soa can claim the failure was due to ECM modification without ever physically seeing or having the motor pulled from the vehicle. The ECM modification is an excuse to not fully cover the repair.
