dmax2017

Had mine done Wednesday. It still brightens a bit but only like 5-10% of what it used to. In my opinion, problem solved. Now all I gotta do is replace these 18" wheels with a set of 20's

Guys, I can relate as mine (2017 Silv 2500HD DA) does the same thing (as expected). I had the truck in for service and talked to my advisor about it. he had never heard of it but he did talk to the GM TAC and they told him that they were aware of the issue and were working on a fix to be applied during an upcoming software update... so stay tuned I guess?
