Yet his original example was from the Chevy HHR forum...Generally GM frowns at publicly available listings of TSB and TSB related materials. If TSBs are behind a "members only" firewall on a forum, GM usually lets it be. If the info is readily available to the public (if Google can find it) then GM will make life difficult for a forum owner/publisher.
The reason for this is that most TSBs include some proprietary information which the manufacturers consider "proprietary".
A listing of available TSBs by title is allowable. The organized posting of entire TSBs is frowned upon, and will earn the bulletin board organizing it a wonderful opportunity for discussion with GM attorneys, after which the TSB area of the bulletin board will usually become "unavailable".
Note: I am not associated in any way with GM other than being a vehicle owner of vehicles manufactured by current or past divisions of GM.
And in both of those sites, the only information available is the TSB number and a summary of what it covers. The details of the TSBs are not shown.A simple Google search brought up this Pontiac Solstice TSB - Read About Pontiac Solstice Technical Service Bulletins | AutoMD
