Within that volume, owners reported 1 crash, 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 2004 W-SERIES is electrical system with 2 filings, followed by service brakes, hydraulic:power assist:hydraulic:hoses, lines/piping, and fittings (1) and service brakes, hydraulic:antilock/traction control/electronic limited slip (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. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 57 investigation files overlapping the 2004 W-SERIES, 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.

20050420CrashSERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP
VEHICLE WAS BEING USE OFF THE ROAD CLIMBING A STEEP BANK. WHEN IT BROKE TRACTION THE DRIVER APPLIED BRAKES AND THE PEDAL WENT TO THE BOTTOM AND WITH NO BRAKING EFFECT. IT HIT A TRUCK FOLLOWING IT DAMAGING THE REAR OF THE TRUCK. THE TRUCK WAS TAKEN TO THE CHEVROLET SERVICE DEPT AND DEEMED TO BE NORMAL. WE TESTED THE TRUCK ON A SIMILAR BANK AND FOUND THE BRAKES FAILED AGAIN UNDER SIMILAR CIRCUMSTANCES. WE THEN TRIED FIVE OTHER CHEVYS (2003 &2004 MODELS) AND FOUND THE SAME BRAKE FAILURE IN ALL FIVE EVERY TIME TRACTION WAS BROKEN. WE HAD REPRESENTATIVES FROM CHEVROLET WITNESS OUR TEST AND ACKNOWLEDGE THERE IS A PROBLEM BUT THEIR TECHNICAL ASSISTANCE SAID THE BRAKES ARE NORMAL. WE CALLED CUSTOMER ASSISTANCE AND DIDN'T GET A DIRECTION FROM THEM. WE ARE WRITING CHEVROLET/GM, BUT DON'T KNOW WHERE OR WHO TO SEND THE COMPLAINT TO. SO FAR WE HAVE HAD NO RESULTS TO CORRECT THIS PROBLEM.

THE VEHICLE IS CURRENTLY NOT FIXED, IT IS A CHEVY 2500HD DURAMAX DIESEL. THE VEHICLE HAS AN INTERMITTENT PROBLEM WITH THE BRAKES FAILING TO STOP! WE HAVE TAKEN SAID VEHICLE TO, TWO DIFFERENT DEALERS, NEITHER COULD FIND PROBLEM AND CONTINUE TO TRY DIFFERENT PARTS. THE VEHICLE HAS A HYDRALIC POWER BOOSTER ON ORDER TO SEE IF THIS RECTIFY'S THE PROBLEM. WHEN THE BRAKES FAIL ITS LIKE PUSHING YOUR FOOT ON THE BRAKE AND MEETING FORCE, BY USING EXTREME FORCE ON THE BRAKE PEDAL YOU CAN BYPASS THE FORCE, HOWEVER THIS CAUSES A PANIC STOP.*AK
