I’m in the same boat now. Blind spot and cross traffic errors after install of PPF. They did break one of my mirror motors which they replaced and I guess the system has to relearn once you disconnect which they did for the install since they take off lights and mirrors. He said to drive it for 50-100 miles and it should reset after he consulted a Ford Tech. It did go away one drive home from work (~18miles) the other day but it typically faults right away when I start driving. It’s been a week since the install. I’m hoping time or maybe a longer drive would fix it but also don’t want to aimlessly add miles and burn fuel in the process. Anything would be helpful regarding specific milestones. I.e. one drive, multiple drives, time/distance, traffic conditions.
Thanks
