Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2017 Subaru Forester owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owned a 2017 Subaru Forester. The contact stated while driving approximately 30 mph and making a turn, the vehicle hydroplaned as the contact lost control of the vehicle. The contact stated that the vehicle inadvertently accelerated while hydroplaning going across 3 lanes of oncoming traffic and hit a curve. The contact stated that the front driver's side tire detached from the vehicle. No one was injured, and a police report was filed. The vehicle was towed to a local tow lot where it was deemed as a total loss. The manufacturer was not informed of the failure. The failure mileage was 28,959.
The incident happened at my workplace parking garage. As I slowly turned left to park in parking spot at work, I heard the engine rev and my car unexpectedly lurched forward very quickly. I stepped hard on the brake but it did not seem effective at stopping the car. I recently replaced my brakes in late August, 2023. As far as I know, before today my car was in proper working order. My vehicle is equipped with EyeSight Driver Assist Technology and I don't believe that the warning collision activated even as the car plowed towards the wall. The car hit the concrete parking block/wheel stop and then the heavy wire barrier at front the parking spot. The wire barrier sits between the front of the parking spot and parking structure wall (I would guess about a 12 inch gap between wires and wall). …
When I pulled into a parking spot in a parking lot, the car seemed to go faster than I intended. I swiped a car next to me, which to me as it was not a tight space. I immediately, turned off the engine and dealt with the passenger of the other vehicle, exchanging information. After sometime, I got back in my car to move it to another location. As soon as the motor was running in reverse, in began to accelerate making a loud roaring noise. I stepped on the brakes, meanwhile going in reverse at an accelerating speed, trying to keep away from cars parked on either side. I also pulled up the emergency brake. At the end of the row, I felt I could move forward without hitting many cars and hoping that in doing so, it would now slow down. It did not. At that point, I thought the only way to stop it, was going to be hitting something. (I did not want to go out of the parking lot into traffic). …
The contact owned a 2017 Subaru Forester. The contact stated that after driving into a parking space in a parking lot with the brake pedal depressed, the vehicle jolted and veered to the right. The passenger's side of the vehicle hit the driver's side of another occupied vehicle. The other vehicle was scratched and there was no injury sustained. The contact stated she then reversed out of the parking space, and the vehicle made an abnormal growling sound. The vehicle then accelerated unintendedly while reversing. There was no warning light illuminated. The contact stated that she depressed the brake pedal continuously but the vehicle failed to respond. The contact then shifted into drive (D), and the vehicle accelerated increasingly. The contact swerved and hit another unoccupied vehicle; however, the vehicle continued to accelerate unintendedly. …
After coming to a complete stop, the vehicle, a 2017 Subaru Forrester suddenly and without driver input surged forward. It crashed into a large garbage can directly in front of the vehicle, crushing it. It then continued forward crushing two whole-home air conditioning units and driving one of them into a brick wall, dislodging and breaking some of the bricks. The vehicle suffered considerable front end damage including the bumper, right front fender, and right headlight. The collision avoidance system should have prevented this occurrence as the flat sided municipal type garbage can was directly in front of the car. Furthermore the front air-bag did not deploy despite the considerable damage to the front bumper.
On May 20, 2022, I was attempting to back into a parking space when my car lunged forward and crashed into two parked cars. I suffered a cracked sternum. No one else was hurt but I was just a few feet from the ground-level windows of a motel. Much body damage to my car (in excess of $13,000) and the other two cars. Police report was filed. Insurance claim filed. No reproduction of problem sought from manufacturer or dealer. No warning signals from car. Assumption made of driver at fault accident. However, please refer to Detroit Free Press article printed 4/22/23: https://freep-mi.newsmemory.com/?publink=0dd2ac172_134ab3a
2017 Subaru Forester- I had arrived to work and stopped at parking spot. Before I could put car in park position.. I heard a car high pitch revving sound. The car throttles forward and hit a building. Now I'm scared of the car.
When operating the vehicle at low and high speeds, the EyeSight system intermittently turns off with a "check owner's manual" message and the system remains off until at least the next vehicle restart. Additionally, after the EyeSight system disengages, when making turns at low speeds (turning corners), the steering shudders (quick violent turns to the left and right), the EyeSight warning light disappears and then re-appears after the vehicle turn is completed. At the same time the vehicle steering shudders, some portion of the internal electrical system appears to be reset (any radio / music system turns off temporarily, and the user-selected display in the main instrument panel resets to its default setting. …
