Well, I went to my dealer today. They had not heard of any lamp replacements for the trucks. I gave him the number and he could find nothing! Finally, he found something. A new bulletin came out dated March 9. Same number, just has an "A" at the end of it. He checked with the parts department and they had none. Said they could not order any because GM stated they were under "review". Whatever that means........ He thought maybe they were still not quite right and GM was updating the lamps again, and then would release. Supposedly, will order them as soon as they can. Guess I will wait until next week and call them and see where we stand.

Anyone have the headlight upgrade today? If so what is the result?

The improvement is significant.

Does anyone know the bulbs part #? My local dealer ordered some for me, but has stood me up on doing the fix. Hoping I can buy the bulbs and have the dealer that I bought the truck from install them. They said they would reimburse me if my local dealer will sell them to me. However, I want to be certain they ordered the right part number..

Got lucky and they had some local. According to my advisor, he said on Tuesday they checked every day my truck was in the shop since the 3rd of March for the TSB and none was found even when I gave him the old 1. Then told him the current 1 on Tuesday and later on found it. Luckily they found a set of bulbs locally or they had it in stock that same day so I picked it up Tuesday evening.

The lighting is significantly brighter than stock. You can actually see in the lanes to the left of you and right of you about a 20 ft ahead of you. Anything closer than that to your sides are still pretty poor, but the lighting has improved.

Had an appointment today so I asked about the TSB. Service advisor stated they'd had complaints but hadn't heard about the TSB. I gave her the number and logged my complaint. They were able to do the BCM reprogram but apparently the bulbs are on a serious back order right now, so I'll have to wait for the full effect

My dealer has the new bulbs on order. So when they come in they will perform the BCM upgrade and swap the bulbs.

 

While my truck was at the dealer they gave me a 2015 Sierra as a loaner. I drove it at night and was surprised by how much better those headlights were. I guess they really were bad in the 2014, I was kind of skeptical, and thought it was just a lot of people complaining.

What was funny about this deal with me is that when I called the dealer I bought my truck from they knew nothing about it. Said they did not have any service bulletins on the issue. Then I called the dealer I go to regularly for service and they knew all about the problem! But had not done any replacements yet because they did not know the new part numbers. I said well I can help you with that and gave them the GMTrucks .com part numbers! HAHAHA! Since then they have done 4 other trucks!

 

I told them they better start watching this chat page for the latest info on GM Trucks! hahaha

Called my dealer last week about the update gave him the TSB number. He order the bulbs for me and had them installed today. He ordered more than two bulbs but only received two. I was the first to get the update at this dealer. I asked him if there have been any complaints about the headlights on the GMC trucks and he said oh yes. He thanked me for the heads up and I thank this forum for the info.

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
