The 1990 GMC K Series has 3 recalls, with two serious safety issues: a fuel line fire risk on diesel models and a brake pedal that can fail completely without warning.
On diesel-equipped trucks, the front fuel feed and return lines can rub against the transmission shift linkage shaft or, on four-wheel-drive models, the front driveshaft. Over time, that contact wears through the line and lets diesel fuel leak near the exhaust crossover pipe, where it can ignite an engine compartment fire. On the brake side, the pivot bolt that anchors the brake pedal to its support bracket can pull free from the bracket's weld nut, leaving the pedal with nothing to push against and eliminating all braking ability in an instant. The third recall applies only to crew cab configurations and covers a missing certification label required by regulation, a paperwork compliance matter with no mechanical consequence.
