The contact owns a 2011 Subaru Forester. The contact stated that the tire pressure warning indicator illuminated. In addition, the contact noticed an abnormal knocking sound in the engine. During routine inspection, the technician informed the contact that the vehicle experienced excessive oil consumption. The technician added three quarts of oil to the engine. Mid-hudson Subaru (1715 u. S. 9, wappingers falls, NY) was contacted, but a diagnostic was not performed due to scheduling. The manufacturer was notified of the failure. The failure mileage was approximately 66,000.
Engine began making loud knocking sound while driving on interstate. I pulled off and parked and called for tow truck. Dealer service reports the engine needs to be replaced. Vehicle has only 63,000 miles and gets regular maintenance. Each time I have the oil changed, the engine is a quart low. Dealer says this is normal. This is hard to believe for a modern vehicle with reduced (partial zero) emissions. I check the oil regularly and am shocked that Subaru sells cars with engines that barely live past the 60000 mile drive-train warranty. Something is fundamentally defective with the design and manufacture of Subaru's engines if this is how they are engineered to perform. I have been looking online and many other Subaru owners are having similar problems. I am fortunate I was able to pull off the interstate safely. Such a sudden engine failure could very easily have ended in a crash.
Car was brought to dealership on June 3rd for knocking sound,I was told it needed a new engine which was replaced, car picked up June 10 after repair was completed. While driving on June 10th in the evening, the car began to buck and kick and not respond to pushing on gas pedal, at one point started to accelerate and then slowed down, pulled over to the side of the road and noted that black smoke and flames were seen coming out from hood. Car burned significantly while firefighters tried to put it out.
I was driving and suddenly heard a very loud knocking noise. The car started slowing down and then stopped. Smoke was coming out from under the hood. The car was towed to a nearby dealership. They determined that the one of the connecting rods punctured the engine block which caused engine oil to shoot through the hole onto the engine block, melting the wiring, and causing the smoke.
