2015 Infiniti Q50 cruise control problems

Came to a slow stop at a red light in my 2015 infiniti q50. My foot was directly on the brake. Within seconds the car began to pull forward and I applied additional pressure on the brakes by using both feet. The engine was racing out of control and the tires were screeching. Sifting the gears did not help. I let off the brake and turned right instead of straight in order to avoid hitting cars. Shifting violentlky the car finally went back to normal.

Engine and/or transmission lost torque power. Since 2016 while car only had 11,000 miles all of the sudden car lost torque power while accelerating. Check engine indicator has never light up and dealer consult scanner has never found the issue. Still car doesnt have same acceleration nor torque while going 0-60MPH. Already I've seen so far 4 cars of the same year with speed sensor problems and replacement. Mechanics say it begins by loosing power until stops working and car wont move.
