Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The first incident occurred when I drove into a parking space, applied the brakes, and the car suddenly sped forward, so I had to repeatedly jam on the brakes to make the car stop. Fortunately, no person or vehicle was directly in front of me. In the past week, we have experienced problems with the ADAS. We were backing into a parking space at night and made contact with a parked car. Our car made no warning sounds or lights to warn us. …”
NHTSA complaint #11510842, filed 2023-03“While driving on I-17 Southbound near mile marker 311 at approximately 75 mph, I experienced a sudden and dangerous malfunction of the Lane Keep Assist (Auto-Steer) system in a 2021 Subaru Forester. The feature was active at the time and unexpectedly veered the vehicle sharply toward the concrete wall on the left shoulder of the highway. I attempted to regain control, but due to the abrupt nature of the malfunction, I overcorrected and collided with the wall on the rear driver side. …”
NHTSA complaint #11672501, filed 2025-07“I’ve owned the vehicle under a year and am already on my second window replacement. I drive the same route everyday and ever experienced windows cracking in any other vehicle before this vehicle.”
NHTSA complaint #11598420, filed 2024-07“Braking system sometimes is activated by a sign on the side of the road, by a tree if we are turning, or nothing at all. Nearly in 2 rear end collisions when the system activated incorrectly. We cannot drive into our garage with the system activated...brakes keep slamming on. The only safe way to operate this subaru is to manually turn it off every time we start the car. Subaru dealership states it cannot recalibrate the eyesight system as it does not have that ability. Dealership is in Corvallis oregon. …”
NHTSA complaint #11522161, filed 2023-05“My Subaru Forester has a significant safety defect. If my web searches are representative this software problem affects multiple models and years of Subaru. I have addressed this problem with the local dealer, Subaru America, and Subaru Japan and have been told that is the way it was designed and it is supposed to do that. As you may imagine that is not a satisfactory answer to a significant safety issue; I can only imagine Ford saying the Pinto was designed with a gas tank that explodes in a collision or a more recent Takata claiming that their seatbelts were designed that way. …”
