Chevrolet Avalanche 2500 Problems
Service 4WD Message May be Displayed
The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.
Popping Noise From Muffler Heat Shield
The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.
Check Engine Light Due to Gas Cap Issue
A Loose or worn gas cap may cause Check Engine Light to illuminate.
Stalling or Low Engine Idle Speed Due to Dirty Throttle Body
A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.
Check Engine Light Due to Restricted Secondary Air Injection Check Valve
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

Learn more »Hydraulic Brake Booster May Fail
RepairPal Expert Overview:
On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.
