2012 Subaru Outback Brakes Problems

The brake pedal suddenly went almost to the floor while attempting to stop. Researching I found there was a recall. NHTSA Recall No. 11V-562. My car was not apparently among the ones being recalled, yet this problem is exactly as described in the bulletin. The component in question is the master brake cylinder. It is available for inspection. It happened on Sat Sept 20 2025 returning from a trip approximately. 300 miles away. the symptom persists. There were no warning indicators.

I took my Outback to my local highly respectable mechanic on August 20, 2025 as I needed the oil changed and the concern I had about having to add brake fluid twice in the past 4 months. He inspected my car immediately and he refused to let me drive it out of his shop as there is a dangerous brake line leaking issue that could result in brake failure. He told me that my Outback is not the first that he had to repair this “Subaru manufacturing defect”. I had to get it repaired. I checked to see if there was a NHTSA recall on my Outback year and there was none, only prior years. Yet when I went online searching more, I found an article that stated that Subaru was going to recall the 2012 Subaru as well? The repair shop owner said to us that my wife is a "gentle driver" and that was good, because, if she had to apply the brakes very hard to avoid a collision, they probably would have failed. Please understand that I read the recall for previous years of Outbacks and other Subaru models, and my Subaru Outback had the exact same defect. I did contact Subaru of America and they responded that my Outback does not have a recall, only prior years. Unbelievable!!! The exact same make and model with the exact same defect and they just blow me off! I was lucky that we did not reach the point of a serious accident. I hope that NHTSA will evaluate my, and I am sure other safety issues with Subaru brakes, and take some action to give other owners the opportunity to make this very serious safety matter right, and avoid an accident. In a related question, can NHTSA somehow require auto manufacturers to inspect their vehicles that are still on the road after say 12 years to helpfully provide some safety assurance to the drivers of their vehicles?

The rear brake lines sprung a leak in a well-known trouble spot with Subarus. The junction area underneath the passengers rear seat is where brake fluid is leaking from. I was driving under normal conditions, went and depressed the break and the pedal went to the floor. The cars brakes were not performing and upon inspection I found the leak. I researched this issue and found that Subaru did acknowledge this issue and other outback model years through recall and technical service bulletins. This is a significant safety issue and should be upgraded to a recall.

The contact owns a 2012 Subaru Outback. The contact stated while driving 20 MPH, the brake pedal was depressed and went down to the floorboard, increasing the stopping distance. There was no warning light illuminated. The contact was able to drive the vehicle to his residence despite the failure. The vehicle was then taken to the dealer, where it was diagnosed that the four-way brake connector was corroded and had started leaking brake fluid. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN. The vehicle was not repaired. The failure mileage was approximately 150,000.

My Subaru Outback, at roughly 110,000 miles, displayed a dash indicator suggesting low brake fluid. After investigating, I found a brake line junction under the car, below the rear passenger seat. This 4-line junction is hidden behind a plastic cover that does have a removable inspection window. The junction's 4-lines are all corroded and at least one is leaking. After finding the issue and researching fixes online, I have discovered that this is a previously-reported problem although Subaru has not taken action to address it. I have not taken action to fix the issue as I am working out the best fix, but will not be driving the car until the leaking corroded junction is repaired.

Our low mileage car which we bought new and is under 10 years old experienced a complete brake failure in our driveway. The brake warning light did then come on. The brake pedal went to the floor when pressed. This event immediately followed a trip with a considerable passenger and luggage load on steep hills where complete brake loss would have been catastrophic and endangered us and the public. The dealer is familiar with the problem (rust-through of brake lines in a specific, well-known location). I am astonished to now learn that earlier years of Outback and other models are the subject of NHSTA 14V-311 and a Subaru product safety campaign WQK-47R to inspect and replace or protect the brake lines that just failed in our car, specifically in the vicinity of the 2-2way connector, however our car is not covered by this campaign. I've attached a picture of the corroded lines on our car which is essentially identical to the picture of the 2-2way connector on https://static.nhtsa.gov/odi/rcl/2014/RCMN-14V311-4153.pdf . This failure is compounded by the lack of a conventional emergency/parking brake, as the steps to engage the vehicle's electronic parking brake while the vehicle is in motion and picking up speed are not obvious.

Brakes failed on the highway and it appears to be the brake lines as outlined in a Subaru Brake Line Recall. Of course I own a 2012 Outback which was not covered and now have a very expensive repair bill. Subaru and the NHTSA annouced that the recalled models include the model year 2008 to 2011 Impreza, 2008 to 2014 WRX and STI and 2009 to 2013 Forester crossover SUV. All affected cars are currently or were formerly registered in the snowy states, where salt is applied to the roads. It was duly noted that these vehicles were previously subjected to another safety campaign, which was given the 14V-311 recall number.

I was driving to work and applied the brakes to slow the vehicle while descending a hill and the pedal went almost down to the floor before the brakes took hold. I got the vehicle under control and proceeded toward the stop sign. I attempted to applied the brakes again and the vehicle went nearly through the intersection before I could get the car stopped. This happened at two more stop signs before I was able to pull into a parking spot at work. After the first stop sign incident, I drove very slowly to work, so as to not use the brakes but for stopping. A mechanic has looked at the car and determined the master cylinder is bad. The part number has been recalled for some vehicles, but not for my car, as determined by the VIN. No warning lights are on. I had two other incidences, on different days, and weeks apart, where I was applying the brakes and went over bumps or holes in the road and brakes momentarily gave out, but after letting off the brake and reapplying pressure the brakes were normal again, and remained so for weeks until this latest episode. I had notified the mechanic at the earlier instances and they noted it might be a problem with my car-make.

FLASHING BRAKE LIGHT AND EBRAKE IS NOT ENGAGING. I CHECKED TO SEE IF THERE IS A STUCK DRUM BRAKE BY JACKING UP AND ROTATING BOTH REAR ROTORS. BOTH ROTORS MOVE FREELY. I CHECKED ONLINE AND THERE WAS RECALL ON 2012 MODELS BUT NOT ON MINE (2012 OUTBACK, 3.6 LIMITED. IT IS DRIVING OKAY BUT I AM AFRAID TO TAKE IT ON HIGHWAYS. LAST YEAR BRAKE LINING THICKNESS ON ALL FOUR TIRES WERE 7MM (SUBARU DEALERSHIP) AND I ONLY DROVE A MAXIMUM OF 10000 MILES. IS IT POSSIBLE THAT OTHER USERS FACE THE SAME PROBLEM AND THERE IS AN ISSUE WITH EBRAKE SYSTEM TOO.

I WAS DRIVING THE CAR WHEN THE BRAKE PEDAL TRAVEL DISTANCE SUDDENLY CHANGED ON ME, WHICH REQUIRED ME TO APPLY MORE PRESSURE TO STOP THE CAR. VERY ALARMING AT THE TIME AND IF I WERE NOT AN EXPERIENCED DRIVER MAY HAVE CAUSED AN ISSUE. THE ISSUE RESOLVED ITSELF BRIEFLY BUT HAS NOW REMAINED IN IT CURRENT STATE, MAKING IT DIFFICULT TO JUDGE WHAT BRAKE PRESSURE TO APPLY -- A DEFINITE SAFETY CONCERN. UNTIL I CAN GET THIS ISSUE FIXED, I HAD TO KEEP THE CAR PARKED. I TOOK THE CAR IN FOR AN IMMEDIATE DIAGNOSIS. SHOP SAID THE BRAKE MASTER CYLINDER APPEARS TO BE FAILING. THEY ALSO ADVISED ME THAT THIS WAS UNDER A SUBARU RECALL, HOWEVER, WHEN ASKING A NEARBY SUBARU DEALER, THEY SAID THE RECALL DIDN'T APPLY. I FOUND THAT TROUBLING SINCE THE RECALL AFFECTS 2012 SUBARU MODELS AND IS A VERY CONCERNING SAFETY ISSUE IF NOT RESOLVED. (NOTE: I UPLOADED THE RECALL PRINTOUT THAT OUTLINES THE ISSUE). *TR
