Key Points

  • The 2011 Subaru Forester has a rather high 15 recalls issued by the National Highway Traffic Safety Administration (NHTSA), covering six main issues: defective airbag inflators, brake line corrosion, faulty power relays, shorts in wiring, faulty rear seatbelt retractor, and a malfunctioning ignition switch that may allow the engine to shut off while the vehicle is in motion.
  • Nine recalls dog the Forester for dangerous Takata front passenger airbag actuators. There was even a recall for the replacement actuator because of the same defective design.
  • Consumers reported issues of excessive oil loss, which leads to engine failure if not caught in time.
  • Other potential problems include unintended acceleration and possible corrosion in the brake lines both of which could lead to a crash.

2011 Forester’s Multiple Recalls for Malfunctioning Airbags were Reissued in Early-2020, Because the Replacement Part was of the Same Faulty Design

Of the 15 recalls on the 2011 Forester, nine are similar for dangerous frontal airbag actuators. These actuators, manufactured by Takata, were only installed in the front passenger side of Forester models and not in the driver’s airbag.

Under certain conditions, an incident triggering the use of the front passenger airbag could result in the actuator exploding and sending metal fragments throughout the cabin. Subaru recommends avoiding the use of the front passenger seat until proper repairs can be made as the airbag will not deploy if the vehicle does not sense a passenger in the seat.

Many customers have reported frustration over the repair process of their Forester airbag recall. The Takata recall impacted tens of millions of vehicles, making replacement parts hard to acquire and repair windows to be extended.

Making matters worse, in early 2020, Subaru issued recalls on previously repaired airbag actuators from prior recalls, because the replacement part was of the same faulty design. It is possible there are defective vehicles still in use by consumers.

Several Forester Complaints Site Unintended Acceleration as Reason for a Crash

The 2011 Subaru Forester has complaints from consumers citing unintended acceleration. Each reported incident to the NHTSA cited driving at low speeds when the vehicle began revving without their input. In some cases, the power of the engine was enough to overpower the brakes and led to the vehicle coming to a stop only after striking a stationary object.

There is no official diagnosis of this issue, nor any recall issued by the manufacturer. Two class-action lawsuits are currently filed for later model Subaru vehicles experiencing the same unintended acceleration episodes.

2011 Forester Experiences Excessive Oil Loss Leading to Potential Engine Failure

The number one complaint registered with the NHTSA is regarding a problem with excessive oil consumption. The engine under scrutiny is the 2.5L FB engine in model year 2011-2014 Foresters as well as some other Subaru models.

The unique design of the engines used in Subaru vehicles, known as a Boxer engine, has been known to have oil burning issues inherent to its design.

However, the Forester’s 2.5L is reportedly burning oil at alarming rates. While not addressed in an official recall from the manufacturer, Subaru has sent out technical service bulletins to its dealers on how to address excessive oil consumption in its vehicles, thus acknowledging an issue.

If not caught in time, an engine without the proper amount of oil as a lubricant can seize and cause enough damage to warrant an entire engine replacement.

In lieu of a formal recall, Subaru has extended the original new-car powertrain limited warranty coverage for excessive engine oil consumption on applicable vehicles to eight years or 100,000 miles from the original warranty start date.

Brake Line Corrosion can Lead to Reduced Braking Power and Increase Stopping Distance

The NHTSA launched a safety recall in June 2014 after it was discovered that salt used to de-ice roads could lead to corrosion of the brake lines. Over time, salt and water coating the brake lines can lead to a gradual brake fluid leak, which can reduce braking power and increase the vehicle’s stopping distance. Ultimately, these issues could increase the risk of a crash.

Subaru also issued a recall in December 2014 for similar corrosion on the four-way connector of the brake line.

This issue primarily impacts vehicles in cold climates with salt as the main method of clearing ice from the roads in freezing temperatures leading the manufacturer to only issue recalls in northern states, however, Subaru will replace the parts of any vehicle regardless of geographical location.

2011 Subaru Forester is a Fan Favorite and Reliable SUV Despite a Couple of Serious Problems that are Being Addressed

Despite the many claims of excessive oil consumption and frustration over the double airbag recall in 2011 Subaru Forester models, owners of Subaru vehicles are extremely loyal and continue purchasing from the brand. With proper maintenance and a diligent eye for any potential oil leaks, you should be confident that the 2011 Subaru Forester is a quality, reliable, and rugged vehicle ready for any adventure.

One Never Stops Learning
Purchased a 2011 turquoise green Forester. The vehicle has 130,800 miles and I am experiencing the dreaded oil leak from the timing head cover, cylinder head gasket, and rear main seal. I have spent about two hours reading so much about the engine needing to be re-sealed and even that in some cases doesn't elevate the oil leaking. I am the type of person who follows the manual to the tee. The biggest lesson I have learned is to do my research in terms of the next vehicle I purchase and what are the challenges. I do hear strange noises and because the noise hasn't happened when I take to my mechanic, it's a bust. Seeking wisdom from the Lord if I should pay and get the engine resealed or look for a new vehicle. The Forester is paid for and that is a great feeling not having a car note. Life on planet earth! Thanks to everyone who shared their story, very helpful.

Don't love it.
Bought new in 2011. I really wanted to love this car, my first Subaru. 130K miles. Burns oil, we are always topping it off. When we top it off it puts out lots of white smoke. Check engine light, traction control, and cruise control dash lights come on and off for no good reason. Sunroof had a leak when we first bought it, which was repaired under warranty. Sunroof is now broken, no longer closes. Gas mileage keeps dropping. Loud interior. Otherwise, the AWD is great in the snow and ice. The few road trips we've taken it did well but we no longer trust it on longer trips.

Was a FANTASTIC car for 10 years…
I bought my 2011 Forrester used in 2013 low mileage. Car has been fantastic for the last 10 years. A few trouble with the speaker system initially but was resolved with dealership. In the last 18 months it has begin consuming oil. I noticed when I had had my oil change recently and then within four weeks it ‘sounded’ like it needed its Oil changed again. Subaru service said that it is likely consuming oil now which is a known problem for this car, but I was never informed of it. So now I guess I have to get a new car.

If it ran better I would love this car.
It runs very poorly. Check engine light is always on and off. The seats are uncomfortable for long drives. Bluetooth constantly disconnects and the USB has never worked. Plastic everything. Windows have to all be opened or it makes a very crazy vacuumed noise within the interior of the car. I have gone through so many batteries in the few years I have had this car.

My forester is forest green making it easy to spot.
Electronic problems on the drivers side that has been “fixed” multiple times but the problem comes back weeks later. The car does perform correctly, but the constant electric problems makes all the dashboard lights go off making it difficult to know what the problem with the car is when there is something wrong.

2011 Subaru forester engine seized within 6 months.
Engine seized within 6 months of purchase. Engine has a problem with over-consumption of oil. Unfortunately, I cannot recommend this car to anyone despite hearing all of the wonderful things about Subaru's and how long they last. This car didn't even make it a year for me.

The 2011 model year had major engine issues where it would leak/burn oil.
I like most things about this vehicle. However, there are some problems. The engine had to be rebuilt and still leaks oil. The paint flakes easily. The metal is very thin so if there is a hailstorm, you take major damage. I would not buy this vehicle again.

The mileage is great! But has some issues
It works okay, we've experienced a few problems with it. But otherwise it is a good car, and it could be worse. The worst thing that is going on with the car is that the door has a piece coming off, so it gets difficult to pull the door shut on the inside.

Pain in the butt but I love the color and the large sunroof.
Transmission issues, engine issues, I have to add a quart of oil every 2 weeks, cylinders misfire, the leather is torn, the push buttons for the back seat recline broken, the switch for the driver seat heater broke, control arms of my suspension broke,

Good in snow, rain, and rough conditions.
I love the 4-wheel drive and it is great in snow! However, it needed a whole new engine and has had various problems. Such as stalling once when driving and abnormal noises. If I had to choose again, I would have bought the Subaru outback instead.

Rough start but doing good now.
Engine blew half way through a road trip, was leaking oil. We then had to pay for the new engine, it to be shipped back to my house, and other services. Since then it has been good; I have only had to pay for oil changes/other minor maintenance.

Old Subaru burns through oil way too quickly!
I've had a lot of issues with the car burning oil. I always have to have my oil topped off between changes. At one point, the engine was spewing oil and had to be resealed. My car makes a lot of noise even when running 'well'

When it is icy and snowy I always get some sandbags for the back of my car.
There is a weird rattling sound that has always been there that is annoying and concerning. The visibility is poor- lots of blind spots. But it is a good car. I wish it was lifted a bit for more clearance.

Workhorse with expensive parts.
The air bags and brakes were recalled. The coolant pipe corroded. The air makes a weird noise when it is on. Positives are it is spacious and a work horse. It is definitely time for a new car though.

Keep up on the oil or you'll regret it!
Keeping up on scheduled oil changes is an absolute must, as well as regularly checking the oil (every 1-2 weeks). It is an oil burner, & has been known for frequently blown engines.

I thought I would love my 2011 Subaru Forester but my 2004 Prius is way better in the winter for driving,twice today I’ve used my AWD and almost spun in a circle- not safe!

Don't buy anything older than 2012 if it's a Subaru Forester.
The engine blew up after 6 months of buying it. But, it is great on space. It is fantastic in the snow. It actually uses oil like it uses gas which is bad.
accountCircle JOHN W on October 18, 2021
It's AWD, good for bad weather and mountain driving.
It's an Ok car. I like it because it's AWD. I wish it could be more heavy duty. A lot of it's parts are plastic which make it feels a little bit cheap.

4-wheel drive SUV kind of like a wagon
Burned excessive oil. Subaru's Factory was very easy to deal with fixing all the recalls
