2016 Yukon Denali won't start

[slackerwil]

Here's my issue. Just drove it last night with no issues. Come this morning, truck won't start, nothing. Couldn't even use my remote key fob. Had to open door manually with the key. Nothing turns on in the truck, no lights, nothing. Tried to jump the battery but no change, still nothing is working. Any ideas?

That sucks! Very weird... keep us posted.

Did you check battery voltage?

Could try disconnecting battery for about 30 mins and then reconnect and see if it resets?

I'm out of town and luckily stuck in the lot of my hotel. Don't have battery meter but will try disconnecting battery.

Sounds like a dead cell in the battery. I bet it's toast.

My 2 year old Interstate battery just flat out died. Never discount the battery being the cause. Even if its not, it's one of the cheaper fixes one can do in the process of diagnoses. Plus, afterwards you have a new battery.

Same thing happened to me on my 15 Denali. I drove home and 45 mins later the car wouldn't start. Completely dead. I check all fuses I could find, etc. I had to call Onstar and get a tow to the dealership. Dead cell in the battery after only 10K miles.

My 07 has done this since day 1. The dealer replaced my battery 4 times saying it was bad. The last time was just out of waranty they said bad battery again. i told them they are full of crap and used that bad batt for another 3 yrs. So it finally did die and replaced it last year. I haven't had a problem for 3yrs untill this week. dead batt twice after sitting only a few hrs. Had the alt and batt checked today and both are good. Just some electrical ghost that prevents power to the starter i think.
I did find that if you get the click and won't start, disconect the pos batt terminal for about 5 min then reconect,then it will usually start.

^^You've put up with that for a decade? It sounds like it's time to get something new.

Thats always in the back of my mind. Just when i think i'm ready for a new one, something always comes up so i have to put it off.

Get something new?
So you can be lucky enough to pay 50k for a 2016 that does the same thing.

LOL.

Oh I didn't know that was a feature that they all have.. I get your point, but you're a little off. All vehicles have issues. But 10 years with a periodically dead battery that nobody can figure out isn't normal. I don't think a 2016 will do that, or a 15 or a 17. But ok 'LOL'

I had a similar dead battery issue on my '15 Denali at the grocery store, that I bought CPO and had owned for ~11 months. One slow start, then after that nothing, the battery had completely died, had to manually unlock the door etc... I brought my Range Rover over to give it a jump with my 'emergency' jumper cables, and nothing... These trucks need alot of current to get started. I went to the auto parts store and got heavy duty 4 ga. jumper cables for about $25 dollars and it started right up.

The battery died again shortly there after, and my wonderful GM dealer refused to address it under the CPO bumper to bumper warranty, so I had to replace it myself.
I'm not sure what the value of GM's CPO is if something dies under the bumper to bumper warranty and it is excluded..., but I'm getting off topic.

Make sure to carry heavy gauge / professional jumper cables for these trucks, and the box fits nicely under the middle seat.

Sorry for such a late response. Got a tow truck the following day (Monday), he decided to try to jump it using a jumper box and it freakin' worked! Damn thing started. Still got it towed to nearest dealer and they checked it out after I told them my situation. Dealer had no answers for me, said battery was fine. Thought maybe I left something on in the truck....I found that hard to believe but who knows. Since then, no issues with my truck.

This sounds like the wonderful pinched wire issue. Interesting if that is the cause and it was on a 2016:

Does anyone know if the pinched wire issue happens on the 2017s?

We've had a new Tahoe for about 2 months. 2 weeks ago had a dead battery. I though it was very strange, jumped it, it charged back. Then yesterday it did the same thing. Took it into the dealer and so far they cant figure out whats going on with it
