What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1998 GMC Z-71, 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.

Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
DT: THE CALLER'S VEHICLE SAYS WAS SLOWING DOWN ANTI LOCK BRAKES KICKED IN. THERE WAS A NHTSA RECALL 05V379000 ON THIS MODEL FOR OTHER YEARS, BUT NOT FOR 1998 MODEL YEAR. DEALER HAS NOT BEEN CONTACTED YET. MANUFACTURER SAID THEY WOULD FIX IT, BUT THEY CHANGED THEIR MIND ON FIXING IT FOR FREE BECAUSE IT WAS NOT RECALLED. THEY SAID TO GET A DIAGNOSTIC TEST AND THEY MIGHT PAY FOR PART OF THE REPAIR. THE CALLER SAID HE COULD GET IT FIXED CHEAPER THAN THE OFFER GMC MADE.*AK
WHEN APPLYING THE BRAKES, DRIVER COULD NOT STOP THE TRUCK, TRUCK TAKEN TO DEALERSHIP, THE POWER VACCUM BRAKE BOOSTER WAS REPLACED, NO BRAKES AGAIN, MASTER CYLINDER REPLACED AT 60,024. CJ
