Apparently, that 500 mile rule, if it is valid, only applies to adjustments such as alignment or wheel balance. If your truck does not start at 100 miles, then they obviously must fix it.

They said GM does not authorize anyone to work on the truck until at least 500 miles.

My dealer had to balance my tires at 12 miles. It had the vibration so I refused to accept delivery until they resolved it. Dealer never mentioned this 500 mile thing.

I have a 2014 GMC Sierra 5.3 crew cab All Terrain Package with this same vibration. I have had it at the dealer twice now with the first time the service writer telling me it was the nature of the beast and the second time the right front tire being replaced but no success. I have now asked the dealer to support me as my issue is not with them but with GM and have asked to have a sit down with a zone rep. I love the style and ride of the truck but if I want to drive a vehicle with a vibration I will get on one of my Harleys. I have yet to hear back from the dealer but will call tomorrow, in addition I will be filing a claim with the BBB and blowing up every message board possible stating facts until this issue is either resolved or GM buys my truck back. I prefer keeping my truck but fully willing and able to take the matter to arbitration/litigation if need be. I suggest everyone else having this problem follows suits as there is strength in numbers! Good luck to everyone that is having this same issue and hope resolution turns out well for you.

I have a 2014 Silverado Crew with 20's. Its an LTZ Z71. The truck has 300 miles on it, I have noticed a vibration on accel. I guess I need to bring it in. Any ideas??? Thanks

mine does that as well as others. My dealer told me its normal that other same equipped trucks do the same. Not sure I believe that but that's why we have the warranty.

Anybody have the motor shimmed with success. I've seen a couple folks claim it solved their problems on other forums and it was mentioned once early on here, but that's it.

Tried driving in town in tow mode. Drone is gone at low speeds. Will try tomorrow on highway speeds. Lower mpg but who cares. No vibration. No top speeds are listed in the book for tow mode.

Read the thread. There are many with the problem. No fix.

You have just made the $50,000 mistake.

Mine does not have any acceleration vibration. No vibration at all actually. All Terrain crew cab with 3.42's and 20's with crap goodyears. That one could be loose plug wire I bet.

try accelerating hard like 10 to 15 mph then stab it like you want to get up and around somebody.

I'll try that later today. If that is when it is happening to you then I would suspect a bad u-joint or incorrectly installed joint. I say that because when you accelerate hard like that the rear end twists the pinion into a higher angle which could make an existing problem worse.

Will let you know what I find.

My 6.2 with 373s also has that vibration on a harder acceleration, to me it feels like it goes with the RPM of the engine like possibly could be the flex plate out of balance or torque converter. It just feels like the engine is out of balance, but also I think I only feel it in first gear then when it shifts to second its gone. The weird thing is I don't think it vibrates in park when the engine is revved. I will mess around with it a little and see if I can narrow it down

    • I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!
    • I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be. 
    • I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!
    • I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify. 
    • I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
