Great, anyone know the service or bulletin number? Went back 10 pages or so with no luck.

 

Btw I have a 2015 sierra if that makes a difference.

 

Go back and start with posts about 500 to 550 or so ..........

You need to confirm your build date as well.

I had my bulb upgrade done Friday. I haven't had any night driving yet but my early morning commute has been better. Forward visibility is much better and I notice a little more further out the sides of the road, which is good with the amount of deer we have around here. I've had some bad experiences with night driving in the rain and it would almost seems like I didn't have a headlights.

Called my dealer today to make app for a few issues, first oil change, and to get the headlight upgrade. I have a feeling it's going to be like pulling teeth to get them to do the fix. When I described my inadequate lighting and asked for help, he replied in a very nasty tone, "Well this is the first problem we've ever heard about with these new trucks." Yeah, so... it sounds like I'm going to be in for a struggle. Maybe I should request he take a ride on my rural route home at 10pm to help me watch for deer?

I just don't understand why this is a struggle for some, and for the life of me these dealers will get paid to do the work i cannot understand why they do not nit pick more while a vehicle is under warranty

I've searched and can not find out where to get my build date, anyone want to share? Looking back thru 40 pages is not fun.

Let me get this straight, our build date as dealer told us is 1/27/15. So, if I am reading the bulletin correctly, our calibration has been done to make bulbs brighter, but we don't have newer bulbs??

 

Have not driven on too dark of roads yet. We specifically bought this truck keeping the built date in mind to hopefully avoid this headlight issue but not sure if we have new bulbs now.

Ok, so I picked up a 2015 Sierra 1500 on Saturday. I've been stalking this forum for awhile now and have been keeping up on this info. Today I brought a printout of PIT5374 to the dealer and inquired about getting this upgrade done seeing as how I predominantly drive at night. He told me that my truck already has the update and bulbs. He said it was only some 14's that did not. Is this true? Is he just trying to pull one over on me?

 

Thanks

Josh

I just got off the phone with my dealership and they were aware of the TSB. They ordered the parts and the update will happen as soon as they arrive. They did state that the parts are on back order.

Very simple. Check voltage to the headlights with engine running (should be 14v) and pop off the cover and see if you have Vosla or Philips bulbs.

Thank you for this, I appreciate it. Vosla is the new bulb correct?

As jamin87ss posted above, the bulbs are not fully seated. If you read all the useful information in this thread, it would have told you that. Go back to about post 500 to 550 and you will find all the detailed information ...........

Ranch, I actually did post @ #500 post. I've been dealing with this issue. I figured it was something with the installment of the bulb. I did read the info. Im just a bit mechanically inclined.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case."

But you and I? We are not doing this.

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!

      By KARNUT · Posted

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.
