The 2003CHEVROLETSIERRA carries 2 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 2003 SIERRA is steering with 1 filings, followed by service brakes (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 57 investigation files overlapping the 2003 SIERRA, and 2 remain open. 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 SERVICE BRAKE BOOSTER LIGHT CAME ON RANDOMLY ONE DAY WITH A BUZZ IN THE BRAKE PEDAL. I TOOK IT IN FOR SERVICE AT THE DEALER WHO HAD $600 WORTH OF SERVICE DONE TO REPROGRAM THE COMPUTER AND LUBE THE 4WD COMPONENTS IN MY 2003 GMC SIERRA 1500 TO KEEP MY TRUCK RUNNING GREAT. HOWEVER, JUST A FEW DAYS LATER I WAS COMING TO A STOP AND MY BRAKE PEDAL WENT TO THE FLOOR, THE EMERGENCY BRAKE LIGHT CAME ON WITH A SERVICE BRAKE SYSTEM LIGHT. I DROVE ANOTHER 20 MILES BACK TO THE SAME DEALER AT ABOUT 15MPH SO I COULD JAM THE BRAKES TO STOP. THEY TOLD ME I NEEDED $1700 TO RUN ALL NEW BRAKE LINES.I JUST PUT NEW BRAKE LINES IN MY 2003 BUICK REGAL SO THE TRUCK IS GOING TO SIT IN MY DRIVEWAY IN HOPES OF A RECALL. THIS IS RIDICULOUS. IF I HAD NEEDED TO STOP IN AN EMERGENCY, I WOULD NOT HAVE BEEN ABLE TO DO SO IN TIME. *TR
