Brake Disc Caliper problems of the 2016 Jeep Renegade

Transmission shifts hard (like a manual on my first day of driving school) upshift and downshift in lower gears. Problem persists in any weather condition as I live in the north east. Brake rotors wear uneven causing pulsation due to sticking calipers.

My vehicle makes a loud screeching noise while driving. When taken for service I was told that the left front caliper has failed and is not releasing. This presents serious issue for braking. According to the dealership the left front caliper is on national back order with no release date, thus indicating that this is a major nationwide problem with this particular vehicle. My major concern is that I cannot even have the problem repaired in a timely manner as the part is on back order with no release date.
