I was heading to work on rt 80 w in NJ when my car's engine began to make a knocking sound. It would not accelerate, and the steering wheel became extremely difficult to turn. As soon as possible I got into the right-hand lane and exited rt 80 via exit 34b, rt 15n towards sparta NJ. I knew there was a gas station at the exit and was just barely able to pull in when the car died. At that point the steering wheel wouldn't turn at all and the car died. The aaa driver told me the car had burned through all the oil (he checked the oil tank; it was completely empty. ) I had the car towed to milford PA where my place of business is as I had perishables I had just bought for my cafe with me that needed to be refrigerated. My mechanic said exactly what the tow truck driver had said. The engine blew due to the car burning up all the oil. No warning lights ever came on before the engine died. Since buying this car I have had to replace the catalytic converters twice, both times before the car had reached 50,000 miles. I have had to have the ignition coil replaced 3 times in under 3 years. The car is a lemon, but no signs were evident until I hit 34,000 miles or so. It is a miracle that I didn't hit or harm anyone on rt 80 when the engine died, or that I wasn't harmed. Subaru of America is very unhelpful; they keep telling me my car needs to be at a Subaru dealer for them to "open a case", even though I explained I had perishables with me and had to keep them cold. I asked if Subaru would tow the car for me, but they said no, as it has too many miles on it. When I asked them about why the warning lights never came on, I was told that my vehicle is "not equipped" with those lights, even though I know it is as they came on when the catalytic converters melted and the driver's manual for my car instructs the driver as to what to do if the lights come on.

Failure Date: 08/08/2016

My car is suburu Forester 2012. I usually change the oil in the car between 7000-10000 miles. On Jan 13-2016, at 71854 mile, amsoil 5 quart synthetic oil was placed at oil change. On Aug 8th at 80600, I went in for oil change and also the car was making knocking sound. The suburu dealer told me engine seized due to lack of oil in the engine. The car was deemed not drivable. There were no evidence of oil leak under the car or around the oil container on the engine, when check by the glassman dealer in southfield michigan. Suburu Forester does not have any engine oil level light. The engine consumes the oil and, the owners should be warned about this. I lost 6000. 00 money on the trade in due to the engine condition.

Failure Date: 09/05/2014

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.

Failure Date: 02/25/2013

I was driving down the freeway at night when I heard a loud bang noise and looked behind me and saw black smoke and had lost all power, no power steering, no brakes and no lights I had to try to cross 2 lanes of traffic to get my car to the shoulder while it was decelerating. I got the car to the shoulder and noticed smoke coming from the engine compartment, and was worried of a possible fire. I got out and called a tow truck and had it towed. The result was a blown head gasket that had blown the rod through the back pillar and sprayed oil over everything causing the battery to short out which led to the power loss. The whole engine on the car needed to be replaced for the second time. Bought car with a rebuilt engine from same problem at 141,000 miles.

Failure Date: 03/18/2012

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.

Failure Date: 06/18/2009

2009 Forester bought in July '08. Less than a year and 20,000 miles, the engine failed. I was driving long distance, and had stopped at a sign when I noticed a load banging noise from hood. As I placed pressure on the accelerator, the car didn't react appropriately - it was slow. The car was towed, and a replacement engine is being installed. I have called Subaru of America for possible buy-back, but no return call. I've read of other similiar cases occurring with the 2009 turbo models.
