The 2002GMCC SERIES carries 3 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2002 C SERIES is electrical system:12v/24v/48v battery with 1 filings, followed by engine and engine cooling (1) and steering (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 2 investigation files overlapping the 2002 C SERIES. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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!
