Traveling in my 2025 Subaru Ascent with cruise control set at 50mph. Bright sunny day, no shadows on the road and no vehicles in front of me. My vehicle slammed on the brakes out of nowhere. Held deceleration about 5-7 seconds and then resumed cruising speed. The road I was on is generally busy. I got very lucky there was no one behind me or I would have been rear ended.

31 May 2026 (AM) Operating vehicle north on MD Rte 147 traveling appr. 45 MPH when vehicle started experiencing uncontrolled electrical activation of features e.g., heat, air, radio, main display. This proceed a shuddering in the drive train like one would experience with a transmission issue. Then, without warning, while at full speed, there was a complete loss of engine power i.e., it turned off, which also resulted in loss of steering and breaking resulting in a complete loss of control of the vehicle. As the vehicle drifted to a rolling stop, the main display indicated to turn off the vehicle and it was forced into park to stop it and then the ignition control button was pushed. The car was restarted and moved off the road. Subsequent restarts and terminations occurred without issue. No fault code was generated or captured by the vehicle computer and the dealer could not reproduce the problem.

The car will spontaneously brake for no reason while driving forward and reverse. The steering wheel will spontaneously steer you out of the lane. The doors will lock while you are in the car and you can't get out for about 30 seconds. The deck door will come down on you unexpectedly while loading items. It has hit us in the head or makes us twist our back to lift it up. The stereo system has a mind if it's own. The eye site goes on and off for no reason. These safety issues concern us. We have had it in the service department three times and they can't duplicate the problem. They have had it since June 6th and drove it 30 miles in 20 days. I don't think they drove it long enough to duplicate the problem. It usually happens after about 15/20 minutes of driving. Typically that is about how long before the brakes will spontaneously brake.

2025 Subaru Ascent has a popping noise randomly usually when turning left. Dealership services can not find the source.

While driving the passenger door window behind the driver burst, then began falling into the car. The safety issue would have occurred if one of my grandchildren were sitting there. Also, the startling event of it just bursting and possible causing a jerk in the car. The dealer said that they have not heard of this and would not repair under warranty (brand new car, purchased in September). Police investigated and saw nothing that would have caused an outside force to break the window. No warnings
