“The acceleration response is decoupled from the throttle. I had come to a complete stop at a stop sign. I tried to move ahead with a slight acceleration to get a view of cross traffic, unfortunately the vehicle accelerated too high and t boned into another car that was going across. The other vehicle was damaged. The problem is more evident while accelerating from slower speeds or from a stop.”

“I was driving in a 4 lane (two on each direction) parkway toward a red stoplight with one car stopped at my lane at the light, I was coasting, slowing down toward the car. When I was about 30 ft away the light changed, the car in front started driving and I applied the accelerator. The distance to the car in front was definitely increasing however my car went into emergency braking mode, cancelling my acceleration pedal action and stopping the car. Luckily no one was behind me as it would have almost certainly ended in a rear-end collision.”

“I pressed on the brake to stop at a red light and felt the car accelerate which caused me to have a panic attack, I quickly released the pedal before reapplying pressure and it self corrected lucky just before light. This has happen before but I erroneously believed that it must have been my fault, this time I was 100% sure it was my brakes. I have also been having intermittent problems with being able press down on my brake pedal due to it becoming very stiff. I was so worried I decide to see if other people had this problem and found that many people had and it was not just me.”

“On september 19, 2018 I was driving my Subaru Outback through big bend national park. I was leaving the chisos mountains basin within the park when it began lightly raining. I pressed the x-mode button hoping it would increase my traction on the winding roads. As the car was coming down fairly steep decline, I noticed that I was gaining speed and x-mode had turned itself off. I came around a curve a little fast and felt that it took more effort than I'd expected to slow the car. At that point, the road leveled out and the rain had stopped, but my speed was still accelerating. …”

NHTSA complaint #11154699, filed 2018-11, 8,000 miles

“The car windshield suddenly cracked on its own without any external or internal impact while parked. The crack started from the top on passenger side and extended vertically to the middle of the windshield. This crack impaired the ability of the eyesight driver assistance system to function properly causing the vehicle to lose safety critical features like forward collision avoidance and lane keep assist.”
