2015 Subaru Legacy

2015 Subaru Legacy 2.5i, approximately 48,000 miles. CVT transmission failed suddenly with no prior warning signs. Vehicle was exclusively dealer-serviced for its entire life. While driving, the transmission began shuddering, slipping, and making metallic grinding noises. Vehicle could barely climb a small ramp and was locked in limp mode, making it unsafe to operate in traffic. Diagnostic codes P0841, P0700, and C1431 were stored. Authorized Subaru dealer confirmed the failure. Technician stated the valve body likely failed first — a known defect per Subaru TSB 16-107-17R — which then caused the CVT chain to slip. Dealer quoted $11,000 for a remanufactured CVT replacement. Service representative stated she had never seen a transmission need replacement at such low mileage. No warning lamps or symptoms existed prior to sudden onset. CVT fluid was never changed, consistent with the manufacturer's U.S. maintenance schedule. This vehicle falls under Subaru's CVT Warranty Extension covering 2010-2015 Legacy models due to known defects. Vehicle is well under the 100,000-mile limit but approximately 13 months past the 10-year time limit. I opened a case with Subaru of America Customer Advocacy. My dealer informed me that Subaru Corporate contacted them and communicated a decision regarding my case, but Subaru has never communicated any decision to me directly. Multiple emails, a voicemail, and a request for escalation have gone unanswered over several days. This failure poses a safety risk as the transmission can fail suddenly and without warning while in motion, potentially with passengers including children.

Incident ~ 5:40 pm, Geneva NY Weather ~ 10 F, not snowing. Background. On or shortly after being started, the vehicle had exhibited prior incidents of extremely rapid engine acceleration not initiated by the operator. Most recently the day before. The incident: I was in the process of very slowly parking the vehicle in a narrow laneway, and positioning the vehicle behind and in line of one other, both parallel to the laneway, in a small area that had been cleared of snow, leaving the laneway open. First, I stopped the vehicle opposite of the parked vehicle's driver side door. Second, I reversed and backed up and positioned the vehicle behind that vehicle. This involved firmly stepping on the brake to stop the vehicle once well behind the parked vehicle. Third, while keeping my foot firmly pressed on the brake pedal, I moved the shift from reverse to forward. At that time, the front wheels were still fully turned to the left. Immediately on completing the shift to forward, my vehicle made a very rapid acceleration. My foot had remained firmly on the brake and had not touched the accelerator pedal. Despite my foot being firmly pressed on the brake pedal, my car surged forward, retracing the path that I had followed while backing up. I could hear the noise of the accelerated engine, and feel the fighting of the brake as the car surged uncontrolled for about four feet and then finally stopped. My foot had been fully depressed as hard as possible on the brake the entire time and did not touch the gas pedal at all. The owner of the parked vehicle observed the incident and expressed concern since the surge was dramatic, and stopped with the right corner of the front bumper of my car within a couple of inches of the left corner of the parked vehicle. The driver's car mat was in the correct position and did not interfere in any way with the operation of the vehicle. I did not inadvertently step on the accelerator. No warning lamps or messages. Cause Unknown.

I am reporting a Sudden Unintended Deceleration event in my Subaru. The vehicle grinded to a halt without driver input. The car stopped in the left lane of a major highway. We put on our hazards and called the state police for help. They were unable to get to us in time. We were hit from the rear. The car's failure created a stationary hazard that led to a high-speed rear-end collision by a Jeep and truck which caused the car to do a 360-degree spin.

The contact owns a 2015 Subaru Legacy. The contact stated that while the vehicle was turned off on two occasions, the contact observed three cracks in the top-middle of the windshield that led to an 'S' shape crack in the middle of the windshield. The vehicle was taken to an auto body and glass shop where it was diagnosed that the lament had pulled away from the glass and the windshield needed to be replaced. The vehicle was repaired but the failure recurred three weeks later. The manufacturer was not notified of the failure. The failure mileage was approximately 76,000.

The contact owned a 2015 Subaru Legacy. The contact stated that while the vehicle was parked, the contact opened and closed the trunk, triggering the alarm system. The alarm system failed to deactivate immediately. The vehicle then failed to restart as needed, and the "Shift to Park" message was displayed while the transmission was in park(P). The vehicle was towed to the dealer, where the brake fuse was replaced; however, the failure persisted. The contact replaced the brake fuse for a second time, but the failure recurred. The vehicle was towed back to the dealer, where an unknown repair was performed. The contact later sold the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 175,000.

Right front wheel started to wobble a bit when braking, as if a rotor started to warp. I purchased a new rotors and pads from Subaru to change the rotor when convenient. I had to stop driving the vehicle because the shaking got so violent when breaking that I thought it was going to damage the vehicle. The rotor had split into pieces along all of the fins. I ended up removing two rings of casting.

The CVT failed and the axle 12

Short Block needs to be replaced ($6,500) Yes, Scenic Subaru has the vehicle awaiting status of repairs (who is paying for service) Yes, my safety is at risk as the oil light has come on during the night when I'm alone on a deserted road. Service Department knows what the problem is - they are seeing alot fot this problem. Unknown on Inspections Yes, warning 'low oil' light came on. The oil light kept coming on. All service and maintenance done by Subaru. Now, Subaru Service Department informed that the Short Block needs to be replaced. From my research, it seems that this is a common problem with newer Subaru engines because they use a liquid engine sealant at the factory and when oil sits on the seals when the engine is not running, the sealant degrades and begins to leak. They also said there was nothing we could have done to prevent this and reiterated just how common with Subaru's. Replacing the Short Block on a car with low mileage (<75,000 miles) should be paid for by Subaru as this is a known manufacturing issue. I should not have to pay for this repair. Also, Subaru said trade in value has dropped due to this issue. Please email or call me as soon as possible.

As I pulled up behind a car that was stopped at a stop sign, I took my foot off the gas pedal, and put it on the brake pedal. The moment i put my foot on the brake pedal, my car surged forward. I had a moment to think, and I confirmed that my foot was on the brake pedal, I had felt the brakes trying to resist the surge. I put the car into neutral, and it jerked to a stop. No one was hurt, I stopped the car in time, but I wondered if this had happened in other settings, what danger it would have posed. This has previously occurred rarely and intermittently when, starting out on some cold mornings, i shifted from reverse to neutral to drive, when backing out of my driveway in the morning.The car surged forward and I had to be quick on pressing the brake pedal hard to get it to stop before hitting a mailbox post. No warning lights went on, in any of these incidents. I called a Subaru dealer, who said there had been no recall history re this uninitiated surge behavior.

We have owned two 2015 Subaru Legacy sedans. Both of them have had major battery problems. We've had to have battery tenders (trickle-chargers) installed on both cars, and we're still having battery problems. We've been stuck in various parking lots, unable to start the car, and had to get jumps from others. This is a royal pain, and a potential safety hazard if we are stuck in a remote location. We've been told by our mechanic that this vehicle does not really "turn off" when you shut it down. There are several devices in the car which continue to have a "parasitic draw" on the battery, which it is not capable of sustaining. We've had the battery and charging system checked out multiple times, and everything checks out fine. Replacing the battery will NOT solve the problem. Replacing the battery with a deep-cycle battery will NOT solve the problem. It is an inherent defect in the electrical system of the vehicle. Available for inspection: YES Safety issue: being stranded with a dead battery in a dangerous location Confirmed by an independent service center: YES Inspected by anyone else: NO Warning lamps or messages: NO

I was in a wreck were my car slammed into the center barrier on the interstate twice and my air bags didn't deploy and I was slammed into my car door I know my friend's dad that owned the car said that the car was totaled and the mechanic that towed the car was wondering why the air bags didn't deploy because of where the car hit and where the damage was

Car battery is draining very frequently which is causing the battery to die. Even for short periods of not using the car, the will fail to start due to the drained battery.

Battery continually dies. Driven daily and even after driving same day battery will be dead. Issue occurs more frequently when headlights are set on auto. Seems battery drains when car is off but still pulling a charge. Have been stranded numerous times since purchasing the car 2 years ago. Have had battery checked and told it is fine.

Driving 55 on a major highway, my car displayed a warning sign “electronic parking brake” and the “brake” light started to blink. It came out of nowhere so I pulled over and tried to figure out what the issue was. Nothing seemed wrong so I drove home. Later that night, the parking brake was fully engaged and did so by itself. I did not engage and it would not disengage. Apparently, this happens to many other Subaru drivers on the internet. This is a major issue
