The 2018 Ford F-650 SD has 5 recalls, the most serious involving brake system issues: corroded brake line fittings can leak fluid and reduce stopping power, and a misadjusted parking brake cable can allow the truck to roll unexpectedly.
A separate concern involves the gear shift indicator: if the cable clip that connects the shifter to the transmission comes loose, the display can show "Park" while the truck is actually in a different gear, creating a rollaway risk. On the lighting side, two recalls affect certain emergency vehicle builds on this chassis where Whelen brake lights can illuminate when the brake pedal has not been pressed, which can confuse drivers following behind.
