“Severe engine failure! Was driving steady speed on highway, then I let off the throttle and heard a bad knocking noise on deceleration. The engine oil temp increased to around 230F. I slowed down to limp it to the next exit and it started jerking. I made it to an exit and the engine stalled at the red light. No smoke, oil level good, coolant level good. Had it towed to Subaru dealer, where they said the engine has severe damage and needs a Short Block Engine Assembly. Warranty was denied because it has a cold air intake. Complained to Subaru Corporate because an intake should not cause catastrophic engine failure at only 38,000 miles.”Owner report · Power Train · Feb 2024
