What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2005 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
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
SPEEDOMETER IS NOT WORKING AND DUE TO RESEARCH ON INTERNET IT IS A COMMON PROBLEM WITH THIS MAKE AND MODEL VEHICLE. DEALER WILL NOT RECTIFY PROBLEM AS A RECALL. *TR
I HAVE A 2005 CHEVY AVALANCHE THAT I AM THE ORIGINAL OWNER AND HAVE RECENTLY HAD A PROBLEM WITH THE SPEEDOMETER NOT WORKING CORRECTLY. SOME DAYS IT WORKS FINE AND OTHER DAYS IT DOESN'T WORK OR THE SPEED IS ALL OVER THE PLACE. I HAVE HEARD THIS HAS BEEN AN ISSUE ON PREVIOUS YEAR MODELS AND GM HAS NOT DONE A RECALL. NO ONE CAN TELL ME EXACTLY WHAT THE PROBLEM IS AND I DON'T WANT TO WASTE MONEY TRYING TO FIGURE IT OUT. THIS IS OBVIOUSLY A PROBLEM GM HAS KNOWN ABOUT AND WILL NOT ADDRESS. THIS IS ALSO A SAFETY ISSUE THAT GM NEEDS TO RECTIFY ASAP! ANY HELP YOU CAN GIVE ME WOULD BE GREATLY APPRECIATED. THANK YOU FOR YOUR ASSISTANCE IN THIS MATTER, REGARDS, MR. ANTHONY TRAPINO *TR

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
SERVICE AIR BAG IS ON AND EVERY ONE ON LINE HAS THE EXACT SAME PROBLEM. IT IS ON ALL THE TIME. AIR BAGS WONT WORK UNTIL FIXED. *TR
SWERVED TO AVOID CAR THAT HAD CROSSED OVER, HEAD-ON, INTO LANE. WENT UP ONTO SIDE (GRASSY AREA WHICH WAS WET FROM OVERNIGHT RAIN). HIT TREE HEAD-ON AT APPROX. 20-26 MPH. AIR BAGS FAILED TO DEPLOY AND SEAT BELT MECHANISM FAILED TO WORK. INJURED SHOULDER FROM SEAT BELT & HIT HEAD ON VISOR/WINDSHIELD. CAR WAS FLAT-BEDDED TO AUTO BODY SHOP. AIRBAG SENSORS WERE CRUSHED IN COLLISION & SEAT BELT MECHANISM WAS FULLY INTACT. THERE WAS ABOUT $15,000-20,000 WORTH OF DAMAGE TO THE VEHICLE. FRAME WAS BENT (BARK OF TREE STUCK IN FRAME). GM WAS NOTIFIED AND WHERE NOT COOPERATIVE. HAD TO PAY OUT-OF-POCKET TO HAVE TRUCK FLAT BEDDED TO A CHEVY DEALER WHERE GM HIRED A 3RD PARTY ENGINEER. TRUCK WAS INSPECTED & INFO WAS DOWNLOADED FROM BLACK BOX. BLACK BOX INFO AND DAMAGE TO CAR DO NOT COINCIDE. WHAT THE BLACK BOX FAILS TO SHOW IS THE INCREASE IN SPEED AFTER VEHICLE HIT WET GRASS. GM SENT BOOKLET STATING THAT AIRBAGS SHOULD DEPLOY BETWEEN 8-14 MPH IN A HEAD ON COLLISION. BBB WAS NOTIFIED BUT BECAUSE I HAVE AUTO INSURANCE, THEY WOULD NOT WORK WITH ME. STATE OF CT REQUIRES ALL VEHICLES BE INSURED. *JB
