Hello! I am new to the forum game, but I didn't find a thread about the issue I have. I have a 2014 Sierra Denali with a 2018 exterior. The issue I have is that the headlights will go out after a few seconds of starting the truck. The lights will stay on indefinitely while the truck is off but after like 3 seconds of starting it, the lights will flicker once quickly and then go out. Scanner can read the signal from the switch getting to the bcm but the lights stay off. To make things stranger, the high beams work just fine, I can turn them on even after the lows go out but only the highs stay on. Is anyone having a similar issue?
TL;DR - 2018 Headlights on 2014 Sierra go out seconds after starting the truck. While truck is off they work fine. Highbeams work fine. Help.

GM recalls 160,000 pickup trucks in Canada for fire risks, nothing announced in US yet
As of right now there is a recall for all GM 1500's years 2014-2018 that have both a rear window defogger and a power sliding rear window.
That recall has not been expanded to the US.
I Just got off the phone with GM and filed a request to have the recall expanded to the US. I would encourage everyone who this applies to in this forum to do the same. It takes about 5-10 min but could save us all a lot of hassle later.
HAVE YOUR VIN READY
Call GM @1 (866) 522-9559
Reference this recall number:
Manufacturer Recall Number
(This is the recall number from GM in Canada)
They will tell you that the recall only applies in Canada and not to your VIN.
Express to them that the recall needs to be expanded to the US since our vehicles are also affected.
Please post here if you have called GM (just so we can keep track)
Please also post if you have experienced this issue (smoke, glass breakage, etc)
Affected components: electrical – rear window defroster on trucks equipped with the power sliding rear window.

It may be a good idea to sticky this topic.
2016-2018 GMC Sierra Elevation grille that's been professionally painted black. This is a brand new OEM grille. I ordered it and decided to go with a different style grille, absolutely nothing wrong with this grille. Shipping to continental US is free, local pick-up near St Louis MO. Price is $500.
Hi all, this is my first ever truck. Came from a ’16 Cadillac CTS which gave me non-stop issues. Decided it was time to try something else. I replaced the CTS with a ’19 Sierra AT4 6.2 fully loaded not too long ago and really loving this truck. Almost too much tech. That 6.2 engine is easily excited 😁. Still getting used to driving and parking such a big vehicle having driven sedans all my life.
My biggest peeve so far is that I almost wrecked it during my first week. I hit a medium bump on the road going 35mph and lost control of the truck as it swerved violently into the left lane. Luckily for me, there was no vehicle in the left lane as I think I would have probably hit it. Really shook me for a while. Chalked it up to not being used to driving a truck. After reading this forum quite a bit, I’ve come to the realization it could be a problem with this generation of the Sierra/Silverado. I’m now extremely careful when I go over bumps because it feels like the truck is sliding. I’ll be monitoring that thread to see if a solution crops up.
Anyways, happy to join this community. Hope you are all nice 🙂.
