Less than a week ago, I recall that someone got called in for the AFM vibration. It sounded like it was a Beta fix from GM. Who was that and did it get fixed?

Atleast you got a manager to ride with you lol

I went yesterday, the manager "left early" even after a GM rep called the dealer to tell them I was going after work to take the manager for a ride so that I can show him the shuddering and hard shifting.

Typical GM lol.

I had the rough idle 80% fixed 2 weeks ago I believe it was. The AFM is the cylinder deactivation, it is physically caused by the difference in velocity of the pistons when 2 or 4 of them (engine dependent) shut down when cruising, the only hope for a fix to the best of my knowledge is new motor mounts which is part of the entire overarching vibration issue. I don't know of any other fix, other than to disable the cylinder deactivation, which inturn diminishes your FE.... technically could call EPA and see if what they think about this issue lol.

Sorry Jesse D, it was not you. I forget the poster's name but definitely not you, it almost sounded like it was new fix for AFM and he was a potential test candidate.

I got one of those automated "how was our service" emails from my dealership, I sent them this back:

 

No Ken, I am not.

I paid over $37,000 for a brand new truck that vibrates almost every time it shifts from 1-4th gear and sometimes going up hill. Terry tried giving me some crap explanation about the truck trying to be efficient, but I'm sure that is what GM has trained everyone to say because apparently this vibration problem is a huge issue with all GM full size trucks and SUV's. At the same time he tried to explain away my vibration issue, your dealership wouldn't actually admit there was an issue by stating "could not replicate issue on my service papers." Nothing pisses a customer off more than being told their problem doesn't exist. There are quite a few very pissed off people out there. There are groups trying to get media coverage and class action suits on the issue. Some people on GM-trucks.com are on their 2nd and 3rd buy backs.

I've been working on cars since I was a young teen, I've even rebuilt manual transmissions. I'm well aware of what a vibration is and the things that can cause it. The truck "trying to be efficient" is NOT one of them.

I have lost all confidence in GM and their dealer networks, and I've owned nothing but GM trucks since 1995. My wife and I will need a family vehicle in the next year or so and I know what manufacturer is completely crossed off my shopping list. The 2011 Mustang we bought brand new has ZERO vibrations after 55,000 miles, and neither did the 2000 Silverado Z71 that I owned for 11 years that I traded in for this truck with 170,000+ miles. I fully regret letting that truck go.

 

A little casual reading on the subject for you (but I'm sure you're likely fully aware of the problems):

Thank you for your time,

I'm sure I'll get a response, but I doubt anything will come of it.

Someone will pop in to say, I follow several different threads so it is hard to tell which one.

For the mods, I posted in that thread that I cant find.

 

Is there a way to view my posts so that I can find it.

Are you on your desktop?

Someone had mentioned the number of used 14/15 trucks on lots.

Driving to lunch today I noticed an excessive number of 14/15's in a medium sized dealers used lot.

 

Sure enough, they have TEN 14-15 used trucks. The 2014's are barely old enough for even a 2 year lease return, aren't most truck leases 3-4 years?

 

Get this, FOUR of them have less than 4,000 miles on them! (looks like my link will only show all used trucks, hit the 14 & 15 buttons for the years to narrow it down). They only have SIX 2007 to 2013 trucks.

    • Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.
    • Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.
    • Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.
    • Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
