Thanks for this post PD12.

 

Yes, thank you. I was getting ready to buy HID's for my truck that is being built this week... I think I will wait and see what the stock lights are like being they have made some changes.

 

Checking with my service manager now to have this done.

 

Glad this was posted. Set up an appointment on 3/16 at my dealer. They'll be performing this.

*Ended up cancelling for a later date.

Be sure to give us an update on the difference. Or better yet, take a picture of the lights before and after the update...

 

I installed HID's already. Would this change the performance or they would operate the same?

I wouldn't think so as the HID's have their own ballast. Hence the 35w and 55w systems.

 

Trying to get this done today thanks OP

 

I doubt you will get it done today, you need to call the dealer and have them order the new bulbs, which I doubt they have in stock yet.

 

Here's the way I understand it, after reading a long thread on GM-Truck about it. Don't take this as fact, as I am just repeating what I have read:

1)Owners that have a HID Kit or LED bulb installed in place of the factory halogen will not see any difference in performance because the bulbs are driven off of a ballast or LED driver & you have already installed a capacitor for the HID kit to work properly during DRL operation and LED bulbs operate at a very low voltage that the driver has filtered down from the incoming 12v.

2) Even if you have a HID or LED bulb kit installed, it would be worth having done while under warranty to prevent issues down the road. After the 3/36 warranty period is up, it will be up to the dealer to who covers cost. Purchased extended warranties will not cover this. All new trucks rolling off the line now have the update.

 

Thanks :thumb

 

I'll have to check into this too. Thanks!

 

Interested in reading the difference you all observe. About to go out of town but will be getting it to the dealer when I get back.

Okay so I picked up the truck from the dealer yesterday after they fix my tailgate lock which was actually the wrong cylinder installed at the factory and they tend to different windows as well to match the rear. While I was there I asked my service advisor about the TSB and he said sure bring them in tomorrow and will get it done but I'm going to call him back today before I bring it in to make sure they have the bulbs so I don't end up leaving it there for 2,3 or four days.

Talked to the service advisor and he said they have to order the bulbs in as there are none in the entire state.

 

...

 

good to know i will be giving my dealer a call.:thumb

 

I'm gonna call & double check that they have the bulbs on order now as well lol

 

this update is for gmc only can anyone confirm?

 

I have many dealers around me one made an appointment to fix it one said it is for GMC only and I have a third looking it up for me so we will see what they say.

 

Went by mine this morning and the service manager had no clue as to what I was talking about. After educating him, he looked more in depth into the issue and found the PIT number referenced by the TSB. He printed it out right there and took it to the parts department to order the bulbs required in the TSB. I still find it amusing that the general public are always the ones educating the "Professionals" at the stealerships. Man...I just cringe at the thought of having to take my truck to any dealership.

So I just want to make sure that I am correct in by saying that a Service Manager who runs an entire department is required to know that a PI for your truck is out and should be fully informed when you come in asking questions about this. I mean they should know everything about every single vehicle that gets manufactured. Then you educating them is the truth. So do us a favor and just keep fixing this yourself because you are the expert and only one who should turn a wrench on your truck. They should just open a tool box and give you all the parts you need when your truck breaks down... because you are the expert

 

Updated the original post, only applies to GMCs.

 

Good thing I double checked, my dealer doesn't have them on the shelf and they have to order them. They said they'll have them there for my 3/16 service date....

*Cancelled 3/16 apt - rescheduled for 4/11

 

Mods please delete two previous posts. Lets keep this on track with facts and Q & A's.

Yeah you really understand service...you are also a hypocrite with regards to your view of dealership workers. I believe you are quoted as saying that they "sound like they are not being truthful..." In a previous post. This couldn't have come from such a saint as yourself recently self proclaimed protector of dealers. I have had lots of dealership workers not even able to explain to me the features of a vehicle that they sell. Not sure what line of work you are in but knowledge of your JOB is important in mine.

This is true because in that case it did not sound as if they were truthful. Not all dealers are a like nor are two workers alike. I bet if you surveyed all of your colleagues with the same questions you would get so many different answers. It is impossible to have uniformity across every employee no matter how hard you try. People lie cheat and steal in every industry. So find a quality person to work with and spend money with them if not do not bring your truck into a dealer. I bet you they will be happy to have one less whiny, picky, nagging person at the door.

 

My dealer in Placerville, CA is legit! Amazing CS
