Purchased 2026 GMC 2500 HD AT4 on Wednesday, the dealership agreed to install AT4 premium package gooseneck/ 5th wheel hitch (puck) premium package system. Upon arriving home I discovered the B&W 5th wheel is not a puck system, but one where you have to reach underneath the bed to pull the pin to remove the 5th wheel. Thinking about calling my attorney Monday as this is a $90k vehicle. What’s the recourse for this? Heritage GMC Buick Rockwall, TX.

What options were listed on the window sticker? Sounds like they installed an aftermarket fifth wheel setup and not the factory fifth wheel/gooseneck option. Not so easy to install the factory option after the truck is built. 
 

The dealer list of options doesn’t look right. The X31 Off-Road Package isn’t usually listed separately on an AT4HD. I could be wrong. 

 

i would talk to the dealer before calling your lawyer. It’s kind of on you to make sure the truck that you are buying has what you want before plunking down $90k.

You won't be able to have the dealer add the puck system.  Its a factory installed item.  

 

People have added it themselves, but its not a dealer installed thing.  You are asking them for something they can't do/won't be willing to do.

 

You have to buy the parts yourself, and install it yourself/find a shop willing to do it.  

 

The real recourse?  Live with what you've got, buy the right truck the first time, or install the factory puck setup yourself.  Put the attorney thought in the garbage.

It's all about what's in black and white. If nothing mentions specifically the puck package, then you didnt buy that option regardless of what the dealership verbally said.

When I bought my 26 3500HD,  I figured out what I wanted. I mean what I needed, then everything I wanted .Then I built one online. Let it simmer in my mind for a few days to do more research.

A couple small tweaks and I built another one online and did a search. 

The exact truck was sitting at my local dealer 3 blocks away.

Now it's in my driveway.

You gotta do your research and not assume anything.

It looks like you got Gooseneck Hitch Package 2 (#84759852)

 

I got the Gooseneck/5th Wheel Package on mine. It also says Stamped Bed Holes W/ Caps and 7 pin Trailer Harness. 

 

I haven't looked into it as I don't have a 5th Wheel trailer.

Might want to read the original post again.

 

OP wanted the factory puck setup as the truck he bought did not come with it.  The dealer added a B&W hitch system instead.

Thanks, I wasn't too sure by looking at the picture to understand what isn't there. It looks like there are 5 holes in the bed. 

 

Is the puck setup the 5th wheel hitch mechanism that attaches to the 5 lugs in the truck bed? All I can see if the ball and the 2 shackle/hook type components. 

 

From what i understood, the larger 5th wheel hitch unit drops into the 5 holes and locks in. I am curious since I have the 5 holes and could move to a 5th wheel in the future.

And by the way the AT4 premium package has nothing to do with the 5th wheel prep package. I might be wrong, but I didn't think the AT4 premium package was a dealer installed item.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
