I'll try to help, everytime something gets replaced on these yukons, that circuit needs to be RESET ! Is there a reset button, on your steering wheel, to reset a variety of functions ? , check owners manual, or call your dealer for better advise
{: ) I wonder how the cables were checked. Did it pass the 200mv voltage drop limit for the negative and positive cables? And do you happen to observe other disturbing symptoms while driving?
You can also try swapping your starter relay (at the underhood fujseblock) with a similar one, also check the relays corresponding terminals on the fuseblock for proper tension. The fuseblock terminals may have loose contacts withe the starter relay.
As for the warranty, it depends on your sales details witn your dealer. Normally a 2007 model is already out of warranty.
