2011 SUBARU IMPREZA Vehicle Speed Control Problems

I experienced a sudden acceleration issue when parking my car in January 2020. As I was pulling into my parking spot and removed my foot from the gas pedal to the brake the gas pedal quickly went all the way to the floor and the car sped forward despite the fact that my foot was on the brake. The car was stopped by a large pile of snow. There was some damage to the bumper. Took the car to the dealership and was told they couldn't find any issue with the car. The problem only happened once to mee but I read of similar things happening with other makes and models of Subarus so I wanted to report it.

THE CLUTCH PEDAL ON MY 2011 STI MAKES A LOUD CREAKING NOISE EVERY TIME IT'S DEPRESSED. WHEN I INVESTIGATED THE NOISE, I NOTICED THAT THE ENTIRE CLUTCH PEDAL BRACKET ASSEMBLY (ATTACHED TO THE FORWARD FIREWALL) SHIFTS APPROX 1/4 INCH EVERY TIME THE CLUTCH PEDAL IS DEPRESSED. I FOUND THAT THE THREE SPOT WELDS SECURING THE CLUTCH PEDAL BRACKET TO THE FORWARD FIREWALL WERE BROKEN. FROM THE OUTSIDE OF THE FIREWALL, JUST UNDER THE WINDSHIELD WIPERS, I SAW THE SPOT WELDS PULLING AWAY FROM THE FIREWALL EVERY TIME THE CLUTCH PEDAL WAS DEPRESSED. THIS ALLOWS THE ENTIRE CLUTCH PEDAL BRACKET ASSEMBLY TO MOVE, CAUSING THE CREAKING NOISE. IF THE BRACKET COMPLETELY SEPARATES FROM THE FIREWALL, THE CLUTCH MAY BECOME COMPLETELY INOPERATIVE - ESPECIALLY DANGEROUS WHILE DRIVING. THIS HAS ALSO DIRECTLY CAUSED THE FAILURE OF THREE CLUTCH MASTER CYLINDERS IN THE LAST 6 MONTHS. 2 OF WHICH FAILED AT FREEWAY SPEEDS LEAVING...
