One problem related to starter solenoid has been reported for the 2008 Chevrolet Avalanche. The most recently reported issues are listed below.
2008 chevy Avalanche. Over a two year period had all 4 door lock solenoids replaced due to failure. When I thought I had doors the doors locked they were not. Cost me about $150 for the first lock--when I raised hell the cevy service manager accommodated the cost of the other three over a period of time--I pointed out when I searched the web is was a major issue, with not just the Avalanche but also the tahoe, surburban and silverado. When I ask if the new solenoid was an improved unit the manager said he did not know but the part # did not change---sound familiar??--crazy!!!! as of one month ago I no longer own the Avalanche. When I told the service manage there should be a recall, he said they only recall for safety issues---I told him that it looked like a safety issue to me--the owner thinks the doors are locked but one may not be.
