2004 GMC Yukon TSBs (Technical Service Bulletins)

There are also 4 GMC recalls » 316 TSBs » for the GMC Yukon.

Please note: The TSB information displayed below are summaries. Unfortunately we do not have access to the full versions. To get full information about a particular TSB, write down the TSB title & date, & either contact your local dealer or click on the links below.

ALSO: The TSB numbers are the NHTSA numbers, which are different from the TSB numbers the manufacturers use to track each bulletin -- yes, it's a very screwed up situation that's almost completely unhelpful to you as the consumer. The manufacturers don't give out their TSB numbers to us, so if you ask your dealer for more information about a TSB, have them look it up by the issue date or the TSB title.
