On its first tank of gas, our old GMC failed to start after being parked for 10 hours because the computer left the ABS system on overnight. It also had crazy software failure modes where the dashboard would go nuts and the onstar system would start making strange sounds.
Arguably, the software was one of the better subsystems of that truck. Never buying GM again. Our old GMC was the best truck we've ever owned. (Much better than our new Ram 1500, which can hold less weight than our old Volvo 240 station wagon).
Hopefully the F-150 electrics aren't hilariously bad.
