2024 Subaru Crosstrek Brakes Problems

On 2/5/2026, my "brake booster" failed while trying to leave the parking lot of a restaurant. When I put car in reverse I had my foot on the brake, I heard an usual sound and quickly realized the brake was not holding as I was moving backward. I had to reapply brake pressure HARD in order to stop, once while backing up and once again to pull forward so I wasn't blocking anyone from maneuvering around me. I was towed to Hanania Subaru where they identified the "brake booster" failed. My vehicle is ready today, 2/18/2026 to pick up and I'll return the Subaru loaner vehicle. Apparently the problem was an electronic failure code and replacing the brake booster was all that was needed. Fortunately, I was not driving in traffic when it failed and I'm told this type of failure is extremely rare. I do appreciate the ability to document this potential hazard to NHTSA.

Automatic braking: One incident of the automatic braking system engaging on a side street when the road was clear of obstacles. The road surface had been prepared for some kind of minor work in the center of the road - there were regularly intermittent disturbances to the otherwise smooth surface. These appeared to be small prox 6-8” square cuts in the surface. On two occasions the car braked suddenly and sharply in front of these disturbed areas. Potential risk from a following car.. Steep, windy road with cars parked on either side. Weather clear. I have not yet reported this to the dealer so it has not yet been inspected. I did not notice any other signs or warning systems prior to this event and during the event I was distracted by the event itself and too busy looking for vehicles that might hit me from behind,etc. to notice.

The 2024 Subaru Crosstrek brakes engaged TWICE without the driver pushing on the brakes, slowing the car down significantly. The initial vehicle speed was around 65 mph on the highway, and slowed to around 45 mph after the second automatic braking incident occurred. Adaptive cruise control was NOT on. The car in front of the Crosstrek was 8-10 car lengths away. Then while the Crosstrek was still moving, a truck hit the back right bumper of the Crosstrek and pushed it into the next lane to the left. (I), the driver of the Crosstrek, was able to steer back into the original lane of travel to the right. After the Crosstrek was steered back to the original lane of travel, it came to a stop due to right rear axle damage. The Crosstrek driver was able to creep to the shoulder to wait for emergency personnel to arrive. The safety of myself and others, due to the Crosstrek (Eyesight?) malfunction, is extremely important to investigate. This safety feature when engaged unexpectedly is dangerous. When drivers do not have control over the braking system of the car, sudden and unexpected slow-downs can lead to rear-end accidents, and even the loss of life. When I was pushed to another lane of travel, a secondary accident could have occurred, or a chain-reaction with many cars. I did not see or hear any warnings, messages, or experience any unusual symptoms before the car braked on its own and I was rear-ended. After I crept to the right shoulder of the interstate, the Crosstrek was still running and there were no warnings or messages. Since the Nov 11 accident, Dean Team Dealership in Ballwin MO has reported the issue. State Farm Insurance has totaled the 24 Subaru Crosstrek, recovered data from the Event Date Recorder (EDR), and is discussing the vehicle losses with Subaru Corporation. [XXX] is receiving chiropractic care also. Additionally, there similar reported incidents on websites—Reddit and [XXX] .

My 2024 Subaru Crosstrek was stopped at a red light behind a car. My cruise was disengaged after the car stopped and my foot was on the brake. Suddenly, the car lurched forward on its own and only stopped when I pressed hard on the brake and moved transmission from drive to park.

The contact owned a 2024 Subaru Crosstrek. The contact stated that while driving at 15 MPH on the slow lane in the snow, he lost control. The brake pedal was depressed but failed to respond. The contact veered to the side of the road, off a slope, and then fell and crashed into a tree. There were no warning lights illuminated. There were no reported injuries or fire. The air bags deployed. A police report was filed. The vehicle was towed to an unknown location. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and the event data recorder was retrieved. The manufacturer was unable to determine the failure. The vehicle was deemed a total loss by the insurance company. The failure mileage was approximately 1,000.

- Pre-collision braking has deployed a number of times without cause (no one in front of vehicle, no collision threat at all. Most recently at 35mph, but at up to 55 mph prior. Feel free to inspect. - Brakes are automatically deployed HARD and without the warning that is supposed to occur. This has thrown me into the seatbelt a few times and poses a significant risk of getting rear ended. I'm afraid the automatic steering system is going to throw me into a ditch. - The dealer can't reproduce it and no log is recorded by the car because it isn't registered as a malfunction, rather the vehicle thinks it's doing the right thing. I've taken it in twice for this and a few other issues. - The vehicle has not been inspected by anyone else as there has been no damage yet. - No signals were given and there have been no other symptoms other than the adaptive cruise control slowing down for no reason on occasion, presumably it thinks there are ghost cars in front of me?
