Everything below is an owner-reported complaint submitted to NHTSA about the 2004 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.

From owner reports, verbatim
BRAKE LINE FAILURE. I WAS APPROACHING A STOP SIGN AND APPLIED THE BRAKES. THE PEDAL WENT TO THE FLOOR AND THE ABS ACTIVATED AND I WAS NOT SLOWING. THERE WAS NO CROSS TRAFFIC SO I LUCKILY AVOIDED AN ACCIDENT. THE BRAKE LINE FAILED DUE TO RUST. BRAKING ABILITY WITH ONLY THE REAR BRAKES ACTIVE WAS VIRTUALLY NONEXISTENT AND THERE WAS NO WARNINGS ON THE DISPLAY. I DO NOT UNDERSTAND HOW THE PREVIOUS INVESTIGATION INTO GM BRAKE LINES WAS DISMISSED.
