Doesn't seem like a Technical Service Bulletin, more like a Product Improvement .....

I believe the GM terminology for a PI is Preliminary Information...

That makes more sense.

 

(although in this case it is an improvement rather than repair)

Why don't you just go ahead and put the Philips 9012 OEM bulbs back in. that way you can "save" the 9011's and have them on hand. If done under warranty, dealer generally will not give parts back to customer.....

Ha ha - that would depend on me being able to remember where I stashed the OEM bulbs in the shop. Fair point about the dealer, although the service center I go to tend to be pretty decent folks so far. While I'd like to get the 9011's back its not going to kill me if it doesn't happen.

 

I've called 3 dealers and none of them have a clue what I'm talking about. Has anyone had any success with this TSB at any dealership here in Socal?

Can't say for SoCal but my service center hand't even heard about it when I called today. They had to look it up and said that they hadn't even gotten the usual email notification about it as of yet. OTOH they also said as long as they could get the bulbs in by the time I brought my truck in for service they would be happy to do the upgrade.

Got my email from the engineer and GM executive offices, bulbs where shipped to my dealer today. Will take it in next week to the BCM update and HVAC update and report back then.

 

Do you have the TSB number for the HVAC update?

Have an APPT for 3/21 to get the headlights updated and an oil change. I had to reference the PIT5374 # to get the service adviser on the same page as I. Based on the before & afters I'm very excited for the update! I was about ready to add some aftermarket driving lights.

Just called local GMC dealer for headlight TSB. Similar to others, i had to give him the document number for him to find it. He hadn't heard of it yet, and even when he searched by TSB number he couldn't find it! Said I was the first person to call about it.

 

Bulbs on order, hopefully it will help these pitiful headlights.

 

Thanks to the guys on the forum who found this helpful info.

I just called my dealer to have my headlamp bulbs replaced and the BCM update competed.. The tech. writer took the document number (4093100) and found the TSB5374. He stated this was only when customers complain about headlamp performance. I lodged my complaint verbally, he was willing to take me in same day to have the service performed. I asked him to check with parts to assure the bulbs are in stock and set a service appointment for 3 days from today.

Update: Took vehicle to dealer today. Service writer was different from the one who booked my appointment. I had to educated him on the TSB and document number. I had to show him the images of the TSB posted on this thread. Once he had a clue off the vehicle went to the mechanic, who in turn, was educated. Then the parts department, who were never informed to order the parts. Half an hour later am informed I will be called when the updated bulbs ship in.

I'm used to this with GMC service,comunication among departments is terrible.

Nobody is getting my 9011's. I am handing them my original 9012's. Dealer did not return my call from earlier today.GM's phone threw a rod.

Went to my service department today, the bulbs are now on order and an appointment will be scheduled when they come in. Since they had no clue about this issue with the lights it would not have been possible to get anything done without a copy of the TSB/PI, which ever it is, that was available on this forum. Handing them a copy got the ball rolling.

 

I'm new to the forum and my truck is now only three weeks old but I was totally spooked by the pitiful headlights lights from the very first night's drive. I feel very sorry for all the folks who have suffered with this and tussled with GMC for a long time to get this resolved. As the new to the party beneficiary of all the hard work of so many people on the forum I just have to say thanks to everyone who made this happen and,I guess, thanks to GM for stepping up and offering a fix.

 

Looking forward to being able to drive (safely) at night.

Well,

 

I could do this with a barely used Yugo I bought in 1991 for $ 1,100, and without having to replace the bulbs. Its stock headlights worked quite well.

Does anyone know if the install a simple as removing a harness and inserting bulbs? Worried about condensation build up in headlamps afterwards. I may just be paranoid, spoke with Service department and they said they'd possibly be removing front bumper. Didn't figure changing bulbs was such a process

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
