Owner-reported complaints filed with NHTSA, grouped by component

What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2002 GMC C Series, 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.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
A NEW DISTRIBUTOR CAP AND ROTOR HAS BEEN REPLACED 2 TIMES WITHIN A 6 MONTH PERIOD. THE VEHICLE TRIES TO START BUT IT DOESN'T CATCH AND THEN SOUNDS LIKE IT'S TRYING TO BACK FIRE. THE AC COIL IS LEAKING ON TO THE CAP AND PRODUCING MOISTURE WHICH IS WHY IT WILL NOT START OR STALLS AND WILL NOT START BACK UP. GMC SAYS THEY HAVE HAD NO PROBLEMS WITH OTHER VEHICLES AND MY MECHANIC SAID THAT THEY CAN'T DO ANYTHING UNTIL IT HAPPENS AGAIN. THIS IS MY 3RD GMC VAN AND HAVE NEVER HAD THESE KIND OF PROBLEMS OR I WOULDN'T HAVE PURCHASED THE 2ND ONE. I'M VERY DISAPPOINTED!

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
