NCAP overall
2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
LOOSE PIVOT BOLT HOLDING THE BRAKE PEDAL TO ITS SUPPORT BRACKET COULD DISENGAGE FROM THE NUT.
Consequence
THIS COULD CAUSE LOSS OF BRAKING ACTIVITY THAT COULDRESULT IN A TRUCK CRASH WITHOUT PRIOR WARNING.
Remedy
RETORQUE BRAKE PEDAL PIVOT BOLTS TO SPECIFICATIONS TO PREVENT LOOSENING.
Defect
ON C AND K MODELS, FEED AND OR RETURN FUEL LINES CAN CONTACT THE AUTOMATIC TRANSMISSION SHIFT LINKAGE CORDON SHAFT. IN ADDITION, ON K MODELS LINES MAY ALSO CONTACT FRONT PROPSHAFT. IN EITHER CASE THE FUEL LINES COULD BE DAMAGED RESULTING IN A FUEL LEAK.
Consequence
A HOLE COULD BE RUBBED THROUGH THESE FUEL LINES, ALLOWING FUEL LEAKAGE NEAR EXHAUST CROSSOVER PIPE; THIS COULD RESULT IN AN ENGINE COMPARTMENT FIRE THAT COULD SPREAD TO THE PASSENGER COMPARTMENT.
Remedy
INSTALL NEWLY DESIGNED FUEL LINE ROUTING BRACKET TO PREVENT CONTACT AND, IF NECESSARY, REPLACE FUEL LINES.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
Yes — NHTSA lists 2 recall campaigns affecting the 1990 GMC K30. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
