January 25th, 2026 13:30 I was coming to a stop at an intersection with my foot on the brake pedal when suddenly my vehicle lurched forward potentially causing rear end collision with the truck in front of me that was stopped at the red light. My vehicle finally came to a stop when I pressed hard on the brake pedal. This problem happened today, so I have not reproduced it. I have not had it checked by a dealer (today is Sunday) I have a Low Tire Pressure light that came on two days ago when the temperatures suddenly dropped here in Tulsa, OK.

A particular corner where the arterial has a y turn. With cruise engaged the vehicle will do the emergency braking even though the lane is clear. Has occurred several times at this same location.
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.
When braking the car shuts down!!!
My HORN only works if car is stopped steering wheel turned to the left. Subaru Dealer says it’s in the steering column mechanism that affects airbag and cruise control also. Says it will cost over $600 to repair. If it preventsthe airbag working, wouldn’t it be a car defect and considered dangerous?

while attempting to come to a complete stop, depressing the brakes, the vehicle continued to accelerate even though the brake was depressed to the floor. At no time was the driver's foot on the accelerator. This is one of 2 incidents with the vehicle.
While parking car in garage, car suddenly surged forward although my foot was off gas and nearly hit end of garage. Engine Temp was relatively cold as it had just been started. This has happened several times before. Reported to dealer service the first time it happened and they did not fix.
My 2015 subaru outback -- have experienced sudden and unintended acceleration. I've mentioned this to the stevens creek san jose dealership when taking my car for maintenance, but they said the behavior is as intended.
Vehicle is equipped with subaru's "eye sight" system, which provides pre-collision braking and is involved with lane departure warning. The eye sight system in my car is intermittently inoperative while the car is in motion. Sometimes, the system begins working again, then turns off, turns on, etc. If eye sight is inoperative as the car comes to a full stop, the inoperative warning message usually disappears, but the message returns shortly after the car begins moving again. This has been happening every time the car is in motion for three weeks.
