What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1999 GMC GMC Truck, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

1999 GMC TRUCK ABS LOST AT LOW SPEEDS I SAW THIS PROBLEM ON THE NEWS. AND I WANT TO KNOW WHAT I HAVE TO DO TO CORRECT IT, SO I COULD TELL MY MECHANIC. IS THIS GOING TO BE A RECALL ITEM, LIKE IT WAS IN CANADA? IF YOU COULD E-MAIL BACK AND LET ME KNOW. THANK YOU DAVID RICHARDS
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
THREE PROBLEMS - INCIDENT DATE NOT EXACT FOR ALL PROBLEMS.1) HAD VEHICLE ACCELERATE IN NEARLY WIDE-OPEN THROTTLE POSITION WHILE BRAKING AT A STOPLIGHT IN HEAVY TRAFFIC. AVOIDED ACCIDENT BY SHIFTING TRUCK INTO REVERSE AND FORWARD SEVERAL TIMES BEFORE I FINALLY WAS ABLE TO TURN OFF ENGINE. HAD TRUCK TOWED TO DEALERSHIP WHERE THE THROTTLE BODY WAS REPLACED. SINCE THAT TIME I HAVE HAD THROTTLE STICK CLOSED. I CONTACTED DEALERSHIP AND WAS TOLD CARBON DEPOSIT WAS CAUSING PROBLEM AND THEY WOULD CLEAN FOR $100.00. I PULLED HOSE FROM BODY AND CLEANED WITH CARBURETOR CLEANER, WHICH SOLVED PROBLEM FOR PRESENT. SHOULD GMC FIX THIS PROBLEM? 2) PARKING BRAKE WORE PREMATURELY. DEALER WANTS $300.00 TO REPLACE. I FEEL THIS IS A PROBLEM EXPERIENCED BY MANY OWNERS AND SHOULD BE CORRECTED BY GMC. 3) HAVE LOUD ENGINE CLACKING NOISE EVERY TIME VEHICLE IS STARTED AFTER SITTING OVER ONE HOUR. DEALERSHIP INFORMED THAT ENGINE OIL PASSAGES WERE NOT DRILLED LARGE ENOUGH AND THAT NO FIX AVAILABLE FOR PROBLEM. I BELIEVE THAT ENGINE FAILURE WILL OCCUR SOMETIME IN THE FUTURE. DOES GMC HAVE A SOLUTION FOR THIS PROBLEM? I KNOW MANY OWNERS ARE EXPERIENCING THE SAME PROBLEM.*AK
CATALYTIC CONVERTER FAILED. *SLC
