rufous03 - apologies for failing to note that NHTSA is for U.S.-only GMC owners. I know there are a lot of GMC owners in Canada. You might be able to find a place to register a complaint on the Motor Vehicle Safety - Transport Canada web page https://www.tc.gc.ca/eng/motorvehiclesafety/menu.htm

 

I'm sure GMC is tired of hearing about the 2014/2015 Sierra headlights, and they would like to put it all in their rear view mirror. These trucks will be on the road for another 10+ years, and GMC's stone-walling doesn't solve the problem. Keeping after them by filing a complaint with organizations like NHTSA or Transport Canada might help - or it might not. The law suit might help - or it might not. But its worth the effort, on the principle of the thing.

 

In the mean time, everyone should be able to get the TSB done, and think about which bulbs you want to use if the Vosla's need to be replaced.

One of my Vosla bulbs burned out two nights ago. Last week I had 3 other bulbs burn out. RR turn/brake/tail, and both of the license plate lights.

 

All replaced now but, for how long? Got 30,800 miles and 30 months on her now, so all the cheap crap is burning out.

 

Wonder how much those Vosla bulbs cost? Anybody know?

 

The Vosla on-line shop sells the 28432 bulb for 29.99 Euros -- around $33 US. http://www.vosla-shop.com/HIR2-30/en

 

A quick search with Google didn't reveal any other sources. The GMC dealer should also be able to order them, but I don't even want to guess the price (I remember the dealer charged off a pretty hefty fee for it against GMC when performing the TSB).

Rest assured I have complained both to GM and Transport Canada, no response from the government to date! Vosla bulbs were a waste of time. I have installed a 36"LED light bar behind the grill that works just fine, but it was not inexpensive. I want GM to step up to the plate and do the right thing for their customers!

 

UPDATE: Dear Sir,

 

We wish to advise that Transport Canada is currently evaluating the situation.

I didn't read thru the entire post so if this has been mentioned I apologize. There is a TSB on the headlight bulbs on the 14 GMC's, I don't know about the Chevy's. They replace the bulbs with a different manufacturer and reprogram the BCM to increase the voltage to them. I just had mine done and it made a huge difference.

TSB #PIT5374 offers some relief -- I rate it as about a 20% improvement over the stock bulbs. The new bulbs, Vosla 28432, do not have a long life expectancy, but everyone with a 2014/15 Sierra before the build date specified in the TSB would probably benefit from having it done at the local GMC dealer. Thanks.

I had it done as well. I was the first one in my state I think to request it at the time. They did help compared to what it was before. Even though those ****ers broke my air box while doing it!!!! I only found out after I replaced the light bulbs with led ones now.

My drivers side Vosla Headlight burned out yesterday. The passenger side burned out a couple weeks ago. Already replaced under warranty but, they are only going to last a year +/-. That will get expensive over time. Will be looking into the modified 9011's, when it's on my dime. Wonder if they are lasting any longer?

From what I understand 9011s are basically a high beam version of the 9012, they have higher lumen output and I think they are of course only meant for intermittent use. They would last maybe half as long?

Hmmmm.... Mine are right at a year old. So far, so good with a lot of night driving. Unusually lucky?

I live 2-1/2 miles off the pavement grid, so that could also be a factor. It's not always smooth sailing!

My passenger side Volsa went out yesterday. Mine are less than a year old. I want to say 8 months but if have to look it up to confirm.

 

Is there a one year warranty on these? Now I'm wondering how long I'm going to want to put up with replacing these things every year or less.

If you are still under 3yr/36,000mi it will be replaced under warranty. If not, then it's on your dime. Mine both went out at slightly under a year as well. It's going to suck. I'm not even sure mine were replaced with the Vosla bulbs yet, even though imade it very clear that I had upgraded to them. Might pull the cap on the drivers side and take a peek this weekend. Maybe it's just me but, they just don't seem as bright as they were before.

It's not you. These bulbs are configured to have a high lumen output and with the PIT were running 14 volts through them. They are gonna get dimmer over time and eventually fail - apparently in less than a year. We need a permanent solution!

      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
