There are 2 owner-reported brakes complaints for the 2017 Subaru Legacyin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I drove into the parking lot of Walgreens, then drove around and pulled into a parking spot facing the south side of the building and put my foot on the brake to stop and park. Instead of stopping, the car suddenly lurched forward violently and slammed into the brick wall of the building. My wife called 911 since I told her my chest really hurt. When the police came, I told them my foot must have slipped off the brake and hit the accelerator, since I had no idea what else might have caused the car to accelerate like that. My wife drove the car home and then drove to the ER where the EMTs had taken me. A CT scan showed that I had a fractured sternum, since my chest hit the steering wheel full force after the air bags failed to deploy. I was in excruciating pain for a few weeks, and after I felt better, we submitted a claim to our insurance company. We then took our 2017 Subaru Legacy to a certified Subaru collision repair center. We were shocked to find that the car was totaled, since it was still drivable. Something kept bothering us about the crash, since EyeSight should have applied the brakes if I had accidentally accelerated and it detected a brick wall in front of our car. After some research, we stumbled on the information about the Class-Action Lawsuit that was just settled by Subaru for reports of Sudden Unintended Acceleration (SUA). The description of what happens with SUA was exactly what I experienced, but this was the first we had heard of it. We were never notified about the lawsuit, even though our VIN number shows our car was involved. Our Subaru dealership had all our contact information since we bought our Legacy from them and they have done all the maintenance work on it. Unfortunately, we released our car to Copart as part of our insurance settlement, so there’s no way to check the EDR data. PLEASE let others know about this major safety issue before anyone else is seriously injured!
TWO WEEK OLD VEHICLE WITH 980 MILES. THIS PROBLEM HAS OCCURRED SINCE DELIVERY. THE BRAKES ARE SOFT AND GO ALL THE WAY TO THE FLOOR WITH NO FURTHER PEDAL TRAVEL AFTER COMING TO A COMPLETE STOP. THIS IS REPEATABLE AND OCCURS EVERY TIME YOU COME TO A COMPLETE STOP AT A LIGHT OR STOP SIGN AND MAINTAIN THE PRESSURE ON THE BRAKE PEDAL. THE PEDAL WILL SLOWLY SINK TO THE FLOOR IF PRESSURE IS MAINTAINED. SUBARU OF AMERICA IS AWARE OF THIS ISSUE AND IS UNABLE TO FIX PROBLEM AT THIS TIME. THEY HAVE ASSIGNED A CASE NUMBER TO MY ISSUE WITH THIS VEHICLE AND ARE WORKING ON IT. THIS ISSUE APPARENTLY AFFECTS OTHER 2017 SUBARU VEHICLES. ONE DEALER TECHNICIAN, AFTER VERBALLY STATING THEY FELT WHAT I FELT WITH THE BRAKE PEDAL, FOUND THAT OTHER 2017S DID THE SAME THING SO WROTE "NO PROBLEM FOUND" ON THE WORK ORDER. ANOTHER SUBARU DEALER ALSO WITNESSED THE PROBLEM AND WROTE ON THE WORK ORDER THAT THE BRAKES FELT NORMAL UNTIL COMING TO A FULL STOP AND THE PEDAL WENT TO THE FLOOR. THEY THEN STATED TWO OTHER 2017S ON THE LOT DID THE SAME THING. I CONSIDER THIS A SERIOUS SAFETY ISSUE AND DO NOT FEEL SAFE DRIVING THIS VEHICLE.
