Horn would sound while driving or when the vehicle is vibrated (example: Door is shut, hood popped open, adjustment of steering column). Had this problem 2 time previously, a GM authorized dealership look at situation and could not find a problem without going into a detail diagnostic. Pulling the fuse for the horn would not stop the horn for sounding. Finally had to pull the horn relay located in the fuse box under the hood to stop horn from sounding. Finally had a detailed diagnostic was performed and the only thing that the dealership could find was a problem with the airbag. Supposedly the airbag expands when it the area around it heats up, which in turn applies pressure on the horn ring, ergo the horn goes off even when the fuse was removed. Dealership could not find an electrical problem during their 2 hours of diagnotics. Recommended soultion replace airbag / horn ring $638 (parts only). Supposedly new airbag has a new design to prevent this from occurring again.

Re: incident AE00013 - the airbag light came on intermitantly, took it to dealer, they couldn't find problem with it. About a mont later the Tahoe started intermitantly losing power when trying to accelerate, causing several near crashes. Took it again to the dealer that then determined the battery was leaking acid on to the airbag sensor. Had to replace the airbag sensor and battery. They charged over $700 to do so, including $89 labor just to install a new battery! about a week or so after that similar loss of power was occurring. Took Tahoe to a different chev dealer who the found alternator was now bad, which I suspect may be related to the ongoing bad battery problems.
