Hello, I had a 2014 GMC Sierra SLT All Terrain. The lights were so poor I did not want to drive at night. I went to the dealership a number of times to complain and was told no the lights are good. Then at some point there was a update when they were going to boost the BCM. Well lights were still terrible. I wrote to Car Complaints and they were a ware of the issue. I was informed there was a law suit started in the USA. I bought a complete new light housing for my truck. Not until I bought my 2017 did my salesman finally admitted the lights were really bad. I live in Canada but hopes this helps. Be safe

so my bulbs blew out again, these ones were bought at the dealership early december and i installed them on dec 2nd or 3rd.

i now have it booked in for service friday for a oil change, squeak coming out of the engine (im guessing a pulley...powertrain warranty..) and you guessed it...NO HEADLIGHTS AGAIN.

 

i thought i would take a look at the bulbs and if you look at the filament inside it is melted... too much power is going to the bulbs, soo much that it has actually melted it...im no expert but that isnt normal...

Was going to help you by measuring so you can compare, but now I’m not.

 

I’ve already given you advice and you just complain and do nothing

Correct me if im wrong but your post was just saying you think that my software was not updated and only the bulbs were changed.

I have had them verify that i have the latest software, and that the voltage is within the current spec, not the previous software spec that the truck was delivered with back in 2014.

Howdy.... I have had my GMC Sierra SLT since 2014, and have been very fortunate in that the BCM voltage increase and German bulbs have worked very well. It has the signature LEDs which include the Daytime Running Light function. Works great. OK, am saying all this, which everyone knows.

 

I just saw a headlamp replacement which "looks" great because it appears to split the lighting for the GMC into separate HI/Lo instead of our current single bulb with the shutter. I'm assuming that would mean the Lo beam could be adjusted to give a wider beam throw than what I have now.

It has the ribbon LED which all vehicles now days seem to be going with.  And the descriptor claims daytime running lights. That ribbon LED is really no biggie to me, I just want to have better adjustments for the illumination. I live in a very dark and hilly area.

Sounds great?!?  However, the descriptor claims this lamp assembly is not compatible with the GMC using the Daytime Running Light.  And it is not compatible with the classic body style. So, am wondering if anyone has tried using it.

Lrymal, have a link to those headlamps? 

 

Curious what type of bulbs are used behind the projector lens. 

 

I have installed the Morimoto 35w HID kit in my Sierra and so far happy with the $180 investment-and not having to remove the grille & bumper cap to install new headlamp assemblies but always interested to see what is new.

It is at Amazon, but really... there is no manufacture's link. The picture has ONEBIGOUTLET and a google search has that place as some clearing service. I listed the descriptor from Amazon which is about all I could find.  

How long have you been using your Morimoto 35w HID kit?

I've had the kit installed since June or July of '17. 

 

I also have a set of the Morimoto XB LED fog lights that I will be installing to replace the factory halogen fogs.

I have LED fog lamp bulbs and am SUPER happy with them. I also installed an HID kit from The Retrofit Source and couldn't be happier with the output form them. For the cost of the HID kit ($170), I would do it again 1000 times over vs using the factory set up. I highly recommend the HID's. With these and the LED fogs, I am very pleased with the visibility at night.

I recently purchased these LED's from diode dynamics. Has anyone had any luck with them?

Just saw the video on the install of these, fitting perfectly behind the dust cap. These look like exactly what I’ve been looking for, but they’re backordered. You get them direct from site? And did you install yet?

PS: The Retrofit Masters is still ducking me in asking for a refund for weeks now! Driver side portion of the kit will not illuminate. I’ve checked the common part swaps yet cannot seem to get it to work.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
