Known issues on the 2015 F-550 Super Duty. Three recalls are on federal record for 2015: a transmission control software error that can show Drive on the gear selector while actually in Reverse, an exhaust gas temperature sensor fault on ambulance and fire packages that can shut the engine down, and an aftermarket suspension kit whose fluid tank bracket may fail.
