Verbatim from NHTSA complaints, newest first
“Concerned over oil being burnt up at a significant rate, have to add a quart per tank of gas. Theres distinct burnt oil smell after driving. Concerned my car needs to be included in the oil consumption recall.”

“I have a single-owner 2011 automatic-transmission Subaru Forester [145k miles]. In a parking lot, I started the car as usual and shifted into reverse. I immediately noticed another car was approaching behind me and reflexively pushed on the brake to give the oncoming vehicle the right of way. As I pushed on the brake, the car suddenly and without warning surged backwards as the engine revved and "stuck" at a high rpm level. Surprised by the sudden loss of control and to stop the lunge backwards, I immediately released the brake pedal and shifted into neutral. I believe this reflexive action was solely attributable to my long history driving manual transmissions which "teaches" your brain that as an alternative to using the brake you can clutch [or if necessary "pop"] to neutral to disengage the engine from the wheels to control the vehicle. People without manual transmission experience would probably keep pressing the brake as their only option to regain control. The car stopped but the engine continued to rev at high rpms for a few moments then returned to normal rpms. No damages. This has never happened before and I was unable to duplicate the sequence of…”

“The contact owns a 2011 Subaru Forester. The contact stated that while driving at an undisclosed speed, she observed smoke emanating from the engine compartment, and the vehicle began to fill with smoke, prompting her to immediately stop and exit the vehicle. Upon exiting the vehicle, the contact observed that the vehicle had become engulfed in flames, and local emergency services were called. Local emergency services arrived and were able to extinguish the flames. No warning lights were illuminated. A fire report was filed, but a police report was not filed. The contact was treated at an area hospital for a stress-related gastrointestinal issue. The vehicle was towed to a tow yard and deemed a total loss by the contact's insurance provider. The manufacturer was notified of the failure but did not assist. The failure mileage was 102,000.”

“My car randomly turns off when reducing speed. It caused an accident a few days ago. I have had multiple mechanics try to figure out the problem but the only thing that comes up on the diagnostic tool is it needed 1 coil replaced. They have all been replaced and still won't go away. The Che k engine light is on. And the car uses about a quart or more of oil everytime I fill up but has no leaks. When I reduce speed the car in traffic, around corners or to stop it constantly turns itself off. Starting it it sometimes turns itself off if I don't give it some gas at the same time. It smells like burning oil constantly.”

“We have come to learn that our 2011 Forester with 95,229 miles is now burning (internally) oil at an alarming rate. The car was making a funny noise so we had it towed to the dealership and they found it was low by 4.8 quarts of oil. The last oil change was at 91,749 and this issue was discovered at 95,229 or 3480 miles driven and 4.8 quarts of oil is "missing". The dealer advised there is no signs of leaks from under the car and where we have it parked, there are no oil spots on the pavement. I have come to learn that in August 2014 then again in April 2016 there was a service bulletin on this engine due to oil consumption. The notice indicated that they (Subaru) was extending the powertrain warranty to 8 years / 100,000 miles. Sadly, we are past the 8 years but not the 100,000 miles.”

“I bought my vehicle new from Oakland Subaru. From the beginning I had to add about a quart of oil every month and a half to two months. I thought this was normal. When my vehicle had approximately 73,800miles, I went to Fremont Subaru for a regular motor oil change. I was asked about the oil consumption. After I reported how much oil I had been replacing on a regular basis, they asked me to return after 1,200 miles to see how much oil my car had consumed. They found out that my vehicle had oil leaks and the engine had to be replaced at 75,000 miles. Subaru paid for the service to be done. Today I took my vehicle to Fremont Subaru for a regular motor oil change which I usually do. My vehicle currently has 134,605 miles. The service representative, Devon Devlugt, informed me that my vehicle is unsafe to operate due to several oil leaks from the engine. The engine has less than 60,000 miles since it was replaced. This is the second time my vehicle becomes inoperable due to engine oil leaks. Fremont Subaru dealership will repair the engine for $4,687. Kelly Blue Book estimates my vehicle to be worth $4,700. Subaru must be held accountable for the vehicles they sell…”
