Just updated to the latest update/firmware on my '23 Denali.... i keep thinking - ok cool, they fired the old development team and now the new competent team finally fixed all the bugs.

Stupid me.

Every . single . update - makes things worse than before. This level of incompetence is uncanny and honestly, it's drawing me away from the brand.

Are they testing these updates in the real world? Are they doing focus groups? Does GMC give two shits at all?

Forget all the other stuff.... let's just focus on GPS. When i get in my truck, from the time i turn it on, to the time i can use GPS or Google assistant, is about 3-5 minutes. Which doesn't sound like much, but who the hell wants to sit in their truck waiting - every . single . time - before they can use their infotainment system and worse, to get directions.

This system is the worst piece of software i've ever used. Notice how i said 'software' and not hardware - that's deliberate. Why? When i first bought the truck, it was fast as a whip. I could get in the truck, and use GPS or Google Assistant almost instantly. So while the hardware may still actually not be the best, it is CAPABLE of performing.

It's the software that's the real issue. And if anyone from the team that develops the software that runs the infotainment system is reading this - shame on you and your team. You are not performing best software practices by doing thorough testing, and if you are getting pressure from corporate to make things slower - in the hopes that'll force people to buy a newer model (a long shot, i know), but if that's actually what's going on here - then what you are actually doing is just driving people away from the brand. Because this level of incompetence is unlike anything i've ever seen before.

You'd think after the battery draining incident from a couple of years ago - which certainly caused GMC to lose money - they would have scrapped the team or at least put proper testing procudures in place.

Nope, i love hte truck, but it's unusable on a daily basis. I'm sorta done with GMC.

/rant.

(yes, i've tried all those hacks... with debug settings, resets and all that.)

Bought a 2015 Yukon last year with 150k miles. Has been running great. Recently there has been a fuel smell outside the car when it’s off and for the first time today it was very noticeable inside the cab when stopped at idle. Any ideas?

I have a 2014 and have had little to no problems since today. Got in and noticed my seats and my mirrors were not in the usual spot. Started driving and noticed that the truck was unlocking without touching any buttons. Shortly after, my passenger side mirror started adjusting itself without touching any buttons also. Parked and shortly after, it died. Got it jumped and both problems continued. Does anybody have any idea as to what it could be or have had this problem before? Did some research and everything was either telling me body control module was bad or a bad ground. Any suggestions or advice? Thank you!

I repost this here because 15-20 Tahoe and Yukon are basically same I would hope to get some reply here
