What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Chevrolet Avalanche 2500, 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
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
Brakes lines broke while in traffic at stop light. Manage to drive in low gear 1/2 block to repair shop. They replaced the lines
SITTING AT A STOP LIGHT THE BRAKES FAILED. HOLDING THE BRAKE WHILE WAITING FOR THE LIGHT TO CHANGE, THE PEDAL ALL OF A SUDDEN WENT TO THE FLOOR. WHEN I BEGAN MOVING I HAD TO KEEP THE TRUCK BELOW 30 MPH TO ALLOW THE BRAKES TO WORK WITH INCREASED STOPPING DISTANCE FACTORED IN. AFTER ABOUT A 5 MILE DRIVE HOME, CHECKED THE BRAKES AND NOTICED A LEAK FROM RUSTED BRAKE LINES NEAR THE DRIVER'S DOOR. TRUCK CANNOT BE SAFELY DRIVEN UNTIL RUSTED LINES ARE REPLACED. NO ABILITY TO MAKE A REGULAR STOP MUCH LESS AN EMERGENCY STOP IN THE PRESENT CONDITION.

Electrical

From owner reports, verbatim
CHEVROLET AVALANCHE INSTRUMENT CLUSTER FAILURES. OVER THE PAST 32 MONTHS THE INSTRUMENT CLUSTER ON MY 2003 AVALANCHE HAS BEEN INTERMITTENTLY MALFUNCTIONING CAUSING THE SPEEDOMETER, FUEL, TEMP, OIL PRESSURE AND ALL OTHER GAUGES TO NOT OPERATE. AS OF 1/19/2008 ALL OF THE GAUGES ON THE INSTRUMENT CLUSTER FAILED COMPLETELY. FROM WHAT I UNDERSTAND CHEVROLET HAS ISSUED A EXTENSION OF THE WARRANTY TO 70,000 MILES FOR THIS SINGLE ISSUE BUT THIS IS A SAFETY RELATED PROBLEM THAT SHOULD BE TAKEN CARE OF UNDER A RECALL OF ALL VEHICLES WITH THIS INSTRUMENT CLUSTER. *TR
