The Ford 5.4 was a problem child for sure but GM has had a lot of trouble with cams being destroyed by the variable displacement motor. The mechanic I use has replaced several motors and repaired others. Before that GM had torque converter problems that took out the transmission. No brand is immune from problems or they would not need mechanics at the service center. The Ram I had before the Ford had to have ring and pinion, transmission and ball joints replaced before 100k miles.
It is AFM/DOD that had failures and it is rare that it takes out an engine. The 3/4 ton and up trucks don't have that issue as those engines don't have AFM/DOD. It was some 5.3s and car 6.0 engines. A failure involves a CAM and lifter swap. I just did it on my Caprice, no failure, but wanted a larger CAM.
