Service Brakes Problems of Subaru Outback - part 1

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 was within the town limits so I was driving slowly. When I approached the first stop light in town I saw that it was red. There were of three or four vehicles stopped at that light. At that point I was probably only going 5mph. I took my foot off of the gas pedal and put my foot on the brake to make a slow stop. Instead, the car accelerated rather quickly. I continued to brake but the car seemed to speed up. I was able to avoid hitting the truck in front of me by going around it. No vehicles were coming towards me but there were some stopped at the other side of the light. I drove up on the sidewalk to avoid hitting anyone. At that point the front passenger side of the car hit & snapped a pole. The car did not stop immediately upon impact. It stopped acclerating and came to a stop about 10 feet past the pole. I am not sure how fast the car was moving when it hit the pole but I was only going about 5 mph when I put my foot on the break. I would estimate the distance my car traveled from the moment I put my foot on the break until the car stopped was approximately 100-120 feet. It felt like the car went into the cruise resume mode and was trying to accelerate to a predetermined speed. I had not been using the cruise control that day but that is exactly what it felt like. There was one other time this year that the car lunged forward without using the gas pedal. It stopped quickly for me and I just assumed that I had hit the cruise resume button, although I also hadn't been using the cruise that day. The insurance company took the car to an impound lot two hours away. I am sure there has been no inspection and my insurance has not informed me of the status of having my car totaled or repaired. Because of the age of the car, and damage, they think it will be totaled. Yes, my safety and the safety of anyone near me was at risk. The car malfunctioned and the fact no one was hurt was miraculous. There were no warning messages before this accident.

I was driving to a medical appointment in ann arbor mi, and was in the area where [xxx] has a few big turns in the road . . . . Like at . . . [xxx] . All of he sudden the car started to accelerate a little on the turn so I attempted to brake the vehicle and I could not feel the brake pedal. I slowly moved into the right lane and frantically trying to slow the car down. I still could not feel the brake pedal and I believe when I hit the speed control off is when it slowed down and I was able to finally brake the car. It all happened in a matter of 10-20 seconds I would guess and it was absolutely terrifying. I have on occasion used the speed control to slow down the vehicle and wonder if that might have some connection. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

I was driving my 2019 Subaru Outback north on [xxx] just north of alanson, michigan on [xxx] when it applied the brakes and made a noise similar to driving on the rumble strip. There were no vehicles in front of me. Scary and now I am nervous driving this car. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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?.

I purchased a car from middletown Nissan on may 24, 2025. The car was assured to have all these different safety checks so far it had to have the power steering pump replaced twice the power steering lines replaced all new control arms a new bearing brand new back brakes which include rotors and pads, and four new tires when the tires were put on they found that the car had significant damage in the subframe from rotting there are holes in it. The car was at the dealership several times for different problems and they never disclose this problem. They basically told me it was my fault when I’ve had the car for two months that the frame is completely rotted. The car is clunking and not driving mechanically the way it should.

On Saturday, August 9, 2025, my brakes failed at highway speed. My vehicle's stopping distance was severely increased, forcing me to perform an emergency swerve into the leftmost lane to avoid rear-ending a truck. The maneuver was extremely hazardous, as it occurred in a construction zone with concrete barriers and no shoulder, leaving no safe escape path and endangering myself and others. I confirmed the cause was a catastrophic failure of the four-way brake line union block due to severe corrosion. There were no warning lamps or symptoms prior to the incident; the failure was sudden and total. I found that this defect is difficult to spot during inspections because the part is hidden by a plastic panel. The failed union block and corroded lines were removed and are available for inspection upon request. My research shows this is a widespread issue and the exact failure mode covered by Subaru recall wqk-47r for 2005-2009 models. This known safety defect persists in the 2010-2014 generation, which is not covered by the recall. Prohibitive dealer repair costs are forcing unsafe workarounds. This defect presents an unreasonable risk to public safety, and I urge the NHTSA to investigate.

Just lost brakes. Was parked at an atm. In park, foot on brake as I was shifting into drive, brake pedal goes to floor and brake fluid leaks out. . . I see there was a recall for brake lines in michigan. I've owned this car since 2020. All brake pads are new as of 4/2025. This just occurred today on Sunday so I have not got the estimate yet.

Several incidents: 1) I was on a 3 lane road and gained some speed to get around a car, when I got into the other lane the car collision warning came on and slowed the car down significantly b/c it detected a car that was at least 300 feet in front of me. That is too far for a car accident. I was told by the dealership that the alogorithum between speed and object detection is what made the car react that way. Essentially it calculated that at the speed I was at I would have overtaken the car in front of me despite the fact that it was hundreds of feet away. This is dangerous and in no way would I have kept that speed and overran that car, besides I was getting back in the other lane to get on the interstate ramp in less than 100 feet. 2) I have small kids, in the morning I unlock the car and load them up into the car while I go back and forth to the house to get the rest of my things. I then started the car heading to my destination. While on the interstate my car kept trying to drag me back into a lane despite me wanting to change lanes. Turns out while I was loading my kids in the car they were searching for their "kids bop" radio station and hit all sorts of buttons, changing my button selection. I did not know how to change it back without reading the book. I had to pull over to the side of the interstate to google how to change the features. I was late to work and completely stressed out. The buttons shouldn't be that easy to change. And frankly shouldn't exist, they are dangerous. 3) today I pull into my parking space at work and the bush in front of me is overgrown, the collision detection system detects the leggy limbs of the bush and slams on breaks flashing the collision notice. My head jerked forward and all of my belongings in the front seat of the car fly forward. This car has a mind of its own. I'm not driving the car, its driving me. These features are dangerous and I want them removed. This car is going to kill me!!!!!!!!!!!.

Lost use of my brakes. Could have been killed. Recall wqk-47 was improperly addressed by using rust inhibitor as band-aid. My opinion and that of a 25+ year ase certified mechanic. I originally wanted the lines replaced and Subaru refused, cheaped out and used the inhibitor. It obviously was an ineffective solution since the whole reason for the recall is now an issue with my car. The lines should have been replaced and really sealed, not cheaply coated with an aerosol spray. The car might be older but is far from rusted out. The other brake lines are just fine. I was expecting something from Subaru, cover the parts or labor at least but nothing. . Their fix was only "preventative" not actually fixing the problem.

Brake pedal went to the floor while applying the brake. Pulled car back up driveway and parked and noted almost zero ability to brake the car, pedal goes to floor when applying pressure to the pedal, almost zero ability to come to stop. Checked fluid - was still in reservoir but not at max. Level (b/n max and min. ). Checked under hood at and no signs of any leaks in engine compartment or on any lines in engine compartment (all good). Looked under car and no signs of leaking. Opened reservoir to top off to max. And by time I went into garage and came back with brake fluid the reservoir was empty, reexamined and found brake fluid leaking from a plastic cover on passenger side rear of car. Placed cover to soak up all fluid dripping/ streaming down to the ground. Called my local mechanic, and he indicated car may need to be towed to be serviced. In looking online, I have found many accounts of this issue with 2010 Subaru Outback owners in northern areas where corrosion at the 4-way connector of the brakes lines causes immediate loss of braking and loss of all fluid. Not sure of cost, but I am thinking once it is examined the 4-way connector and all 4 brake lines may need to be replaced. This appears to be a widely known issue and for some reason this was never included or changed from 2005-2009 Subaru recalls to change for 2010 models, so I would like to know why this and the cost for repairs are not covered by Subaru as a recall. This could have caused a major accident and severe injury or death if traveling at speed on highway or in area needing hard braking to come to immediate stop. This is now the third major issue I have had in less than 12-months and 2nd from corrosion on my 2010 Subaru. Last summer my front frame had corrosion damage and required replacement. This brake issue with corrosion at the lines to the 4-way connector had recalls in earlier models, but why not in 2010 Subaru Outbacks? very unsafe and no warning light prior to brake loss !.

I was driving home when my brake pedal went all the way to the floor. Next, I realized I could not stop the vehicle. I was able to pull over and stop. A puddle was pooling under my vehicle by the rear passenger tire. I received no lights or illumination or warning.

While in a dairy queen drive-up lane, I stepped on the brake pedal and it went right to the floor. The car did not stop, causing me to hit the car in front of me. When backing away from the car in front, the brakes again failed and I hit the car in back. I moved forward again , swiping the car in front again. The cars were merely feet apart and my car was thankfully moving very slowly. Had I been traveling at a higher rate of speed there could have been serious injuries. Car was taken to an auto repair shop where the mechanic experienced the same problem with the brake pedal. He says the pedal went to the floor and the car wouldn’t stop. Car is currently at a collision shop where they report that inspection of the brakes is normal. They also report that the brakes worked when they pulled the car into the shop. The car has not yet been moved to the Subaru dealer service department for inspection of the brake pedal. There were no symptoms, warning lights or messages before the incident and there were none found by the shop after. My car was built in the same time frame as those involved with recall #19v664000 which involves the brake pedal mechanism although my VIN was not included. The car is available for inspection. I initially received a ticket but it was dismissed after the repair shop owner reported the same failure.

When braking the car shuts down!!!.

The contact owned a 2009 Subaru Outback. The contact stated that while driving 65 mph, the brake pedal was depressed and went to the floorboard, and the vehicle failed to respond. The contact swerved to avoid a crash and moved over to the median. The contact stated that the vehicle spun around, and the contact used the parking brake to stop the vehicle. The contact was unaware of a warning light being illuminated. The contact stated that on another occasion the air bag warning light intermittently illuminated weeks before a crash. The driver’s and passenger’s side air bags failed to deploy. A police report was not filed. There were no injuries sustained. The vehicle was towed to the residence. The vehicle was not diagnosed or repaired. The insurance company was not contacted. The manufacturer was not notified of the failure. The contact stated that there was a gasoline odor coming from the engine weeks prior to the failure. The failure mileage was approximately 106,000.

My brake warning light came on as I was driving down a steep decline on a narrow road. When I found a safe place to pull over I found I had very little brakes. It was found that once a plastic shield was removed from the rear of the car that the plastic shield was full of mud and water and had corroded the brake lines causing the brake fluid to drain out of the system. It appears there was a recall for this but only in salt belt states. I have only owned the car for a year and it does not show any outstanding recalls.

I noticed my brake pedal suddenly sink to the floor, and I have to press the pedal all the way to the bottom to get a little bit of brake. Was able to make it back home. Upon inspection, I noticed brake fluid dripping from rear passenger side brake pipe, I took off a plastic cover that covers the brake line, and noticed heavy rust on a "manifold" where two brake lines coming from front of the car and two lines going to two side of rear brakes. The brake line is leaking right from there. I feel sudden failure of this part can lead to fatal accident, luckily I was very close to home and on a local road when I experience this. And Subaru should 1. Make it more easy for inspection. 2. Notify the public. 3. Get more rust proof measures, 4. Get it fixed for the current owners. Thanks.

Complete brake failure due to leakage at 4 way b8rake line junction located above the gas tank on right side rear of vehicle. Known and reported issue due to rust and corrosion of brake lines in this unprotected area of vehicle. It has been a known problem on these 4th generation vehicles. . . No recall instituted. Wife and I lucky to be alive. Ridiculous that Subaru America has not been summoned to conform to a nthsa recall and make repairs on those vehicles affected. Absolutely no indication failure was about to occur resulting in complete brake failure. Amazingly, this happened in such an area where I was able to roll to a stop and take action to transport the vehicle to my home where it is officially grounded in my garage. Condition was confirmed by a Subaru master technician.

My car had an unintended acceleration that caused me to go in a ditch and hit a tree. I could not get car to stop when I realized it was increasing speed. It all happened very fast. My car was totaled. All airbags deployed. Front right side of car was completely destroyed. There were no warnings. My insurance company has the car on their tow lot. I have sprains and bruises on my right side and a slight concussion. So thankful that I was not in a parking lot or in heavy traffic or near any walkers.

The front rotor warp excessively causing the brake pedal and the entire car to shake uncontrollably. The entire front brake assemblies were replaced at Subaru of coconut creek. Our safety was definitely at risk as it was very hard to brake going downhill with the brake pedal and the car shaking uncontrollably. The dealer confirmed black spots on the front rotors and warped front rotors. There were not warnings prior to, during, or after the shaking. Going downhill was made very uncomfortable. Subaru of coconut creek services the vehicle and notified me of the black spots and warped front rotors. There was nauseating burning smell coming from under the hood and we had to wait 15 minutes for it to disssipate.

The car was being driven down the road, when the brake pedal went soft. At that point the vehicle had lost all braking power. I pulled the vehicle over to the side of the road and proceeded to check the vehicle. The vehicle brake reservoir was empty, and the line underneath the car was leaking fluid out. Then I called a tow truck to tow my vehicle to get repaired. The mechanic then told me about the recall wqk47r.

The brake system had a total failure. Driving down the road and the brake pedal went completely soft and was not providing any brakes. The vehicle was pulled over to the side of the road where the brake fluid resivor was empty and the underneath of the car was wet with brake fluid. The vehicle then was towed to a nearby mechanic to be inspected where they have come to the conclusion that the brake line box has become coroted. During the brake failure there were no warning signs and the only thing that prevented the vehicle from being involved in an accident was the use of engine braking and going up hill. The reason I’m reporting this is because after reviewing the internet to see what the average cost of the repair should be I came across a forum where this issue is become common place in my generation of Outback, as well as the previous generation which has a recall already on this same component. I’m also writing this report because I’m concerned with the amount of this type of vehicle on the road still and having a similar issue.

Going down the road and my breaks went to the floor, further inspection the back passenger 4 way block blew apart due to rust I looked online and there is so many of these cars the same year that this is happening to, would love to have this year and model included in the recall for breaks to get this fixed.

The contact owns a 2019 Subaru Outback. The contact stated that the air bag warning light was illuminated. The computer control system showed low tire pressures. While the passenger’s seat was occupied, there was an abnormal dinging sound detected. The message that the seat not activated message was displayed. The contact stated that the battery drained, and the vehicle failed to start. The starting system had drained battery. The contact had triple aaa check the vehicle, and the dcm made an abnormal popping sound. The abs, radio, and cd warning lights were flashing. The transmission, gps, and undercarriage message were illuminated. The computer screen had burned out and was inoperable. The contact stated while driving 60-65 mph, the vehicle abruptly stopped without driver input. The steering wheel became inoperable and was uncontrollable. The vehicle was taken to the local dealer, where it was diagnosed and determined that the dcm needed to be replaced. The vehicle was repaired. The manufacturer was contacted, but no assistance was provided. The approximate failure mileage was 55,000. The VIN was not available.

The vehicle has received all scheduled and regular maintenance. I was driving right around the speed limit of 50 mph. Traffic was stopped ahead, and I had plenty of time and space to stop. I pressed the brake pedal, but continued to coast. I pressed it harder, all the way to the floor for at least four seconds, and there was no resistance, no feel of the antilock brakes kicking in, no emergency braking to avoid a collision, and no braking or slowing whatsoever. I could not safely swerve out of my lane, as there was no shoulder on my left and traffic on my right, and so there was an accident. The vehicle is currently at the body shop, and I told stare farm about the brakes, but they have no intention of investigating it.

Lost brakes. Corroded brake lines. Recall was completed for this very issue. Fix was ineffective.

The left front drive axel cracked while we were driving on an overpass connecting two highways. We didn’t hit or bump anything. The car just stopped, like the brakes were slammed on, except the brakes didn’t work. As we were on an incline, the car started rolling backwards, but fortunately the emergency brake worked. It happened so abruptly, I wasn’t able to fully pull off the road and my children in the back seat were screaming for their lives as truck after truck whizzed by rattling our car with their horns blaring missing us by inches. The police and fire trucks eventually blocked us from traffic until we could get a tow. The engine worked, but we couldn’t get into any gear. The mechanic said it must’ve been a faulty part to have gone like that. When the axel broke, it damaged the front differential and the transmission so the car isn’t very drivable. On a less dramatic note, a month earlier, both back doors stopped working on the same day!! the child locks failed and the doors couldn’t be opened. I consider this a safety hazard, so we spent $$$ to fix it. As we take good care of our car, I am very curious why it’s failing so spectacularly all at once.

To the CA automotive repair bureau, [xxx] complaint, in 2022, I bought a new Outback at albany Subaru. In October 2024, my car has 33,000 miles and I've had all of my 3,000-mile oil changes, inspections, and warranty repairs done by albany Subaru. I pay $100 for each repair that's covered under Subaru's extended warranty. In 2023, the car's dashboard computer/radio head unit was repaired, I drove the car for a few days, but the head unit was defective, so Subaru changed the head unit. This cost me (3) three trips to Subaru, which is 7. 8 miles from my home, uber costs, and three $100 warranty payments. I'm a small business owner and had to pay employees extra to remain at work so I could drop off and pick up my car. Most times Subaru didn't give me a loaner car. Weeks later, I was driving up a hill and could not correctly steer my car, I thought I might crash, so I stopped driving my new car. I only drive on paved roads and I bought my Subaru because of Subaru's quality and safety reputation. I returned my car to albany Subaru. My car's steering or front end seemed loose and not right. Subaru told me I needed an alignment. I paid for an alignment. I drove my car home, but again, the steering didn’t seem right, it was still loose and shaking. A day later, I returned my car to Subaru and they readjusted and tightened the steering box. Subaru called me at home and stated I needed an oil change, an alignment, and (4) four new tires, and brakes, which I agreed to the oil change. The next day, I picked the car up and spoke to the service managers about my concerns with the new car steering, and stated to them that Subaru bloggers are sharing that there should be a recall on Subaru steering columns and other repair issues that could result in lemon law lawsuits against Subaru. The service manager nikki ali and a mechanic stated that Subaru has steering column issues but that Subaru has not yet issued a national recall, but may replace steering columns. Information redacted pursuant to the freedom of information act (f.

The brake system failed when the brake lines burst at the four way connector on the right, rear side of the vehicle. There were no indicator lights lit on the dash until after losing all braking. Luckily I was traveling slowly and was able to roll to a stop safely. This is due to corrosion on the brake lines in the area of the four way connector. There is a small inspection door on the cover for this connector, so the issue is easily seen. This has been an issue for Subarus in the past with many recalls for this issue on similar models. Unfortunately the recalls end in 2009 for Outbacks while mine is a 2010. Obviously this issue has not been corrected by the manufacturer.

While turning into a parking spot my wife had foot on the brake and vehicle accelerated over parking bumpers and into a fence and ultimately was stopped by a combination of a tree and the fence car drove through. This collision prevented her from crossing pedestrian sidewalk and continuing into southbound traffic lane of state hwy. This incident put not only my wife at risk but also potentially any pedestrians or southbound vehicles. There were no system failures or warnings prior to my wife's arrival to her appointment. As mentioned this occurred within an approximate 5 second time frame. It is unknown as to what if any warnings occurred prior to/during the crash as my wife was pushing the brake to park when the sudden acceleration occurred. The braking system seems to have failed along with the sudden acceleration. The automatic braking system didn't engage, nor did the parking collision system. All our other Subaru's (including this vehicle have the collision warning and automatic braking systems) the dealership did not try to replicate the incident but all warning systems appear to be functioning correctly at this time. Following the accident I first reported the incident to my dealership where I purchased the vehicle. The initial damage estimate is forthcoming but Subaru tech indicated it will be may thousands of dollars to repair. I will follow-up next with Subaru's national customer care (per conversation with dealer) at the dealership (southern oregon Subaru) I had a safety/drive-ability inspection performed. Vehicle was given a clearance to drive, but obviously my wife refuses to drive it. Subsequent to the accident, we learned there are over 200 similar reports to NHTSA for this exact issue. We will also submit claim to insurance provider usaa.

Bought vehicle from carvana, immediately noticed transmission shudder issues when driving near 50 mph. Brought vehicle in to multiple repair facilities. It had warped brakes, bad calipers, needed a new torque converter at least and the repair shop recommended a total transmission replacement. The whole vehicle shakes when driving near that speed or braking.

The contact owns a 2011 Subaru Outback. The contact stated while driving approximately 30-35 mph and approaching a truck, the brake pedal was depressed and travelled down to the floorboard, causing the vehicle to fail to respond. The contact stated that the truck that was in front of the vehicle made a turn, which prevented the vehicle from crashing into the truck. The contact stated that he was able to pull into a parking lot, where the vehicle rolled until it stopped. The brake warning light was illuminated. The contact stated that his wife who had just undergone a spinal surgery was occupying the front passenger's seat when the failure occurred. The contact was able to drive to the residence. The vehicle was towed to the dealer, where it was diagnosed that the brake lines had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the repair could not be covered because the VIN was included in an unknown recall. The failure mileage was approximately 127,000.

Rear brake lines at junction block right rear corroded. As is the sane situation with 2009 models and under and impreza models newer with same design cannot understand why this model year was passed by.
