Wow...I have a standard bed (two piece drive shaft) and have had nothing but issues with the vibration. So far they have replaced Wheels, tires, driveshaft, changed pinion angle, and changed spacer on driveshaft...been in the dealership now for over 5 weeks. I paid 50K for a piece of SHIT truck and now GM wants to trade me out for something else. I was told the issues were in the Standard Bed (two piece drive shaft) so now I hear that its a short box it makes me skeptikal. Not sure what to do....

 

Man that is tuff. I would not be very happy with this either. All I can say is have you had someone besides the dealership look at the tires and do a road force balance? On my 90 GMC sub, when new, we put on two sets of Michelins trying to stop vibration. I finally just took the second set on the truck to a good tire shop and dang no vibration after a good balance. Good luck on this. Maybe another truck as some/most here are OK?

Well just got off the phone with my dealer and shop Forman asked me when I could go test drive another 2014 Silverado off there lot so I could feel that they all had the same vibration. wow what trucks did we buy?

Spoke to Gm specialist and they told me there is no fix at the moment we are stuck with our vibrating trucks till they find solution. Has anyone heard anything else? What is your dealership telling you?

Harmonic vibration? Next time you feel it listen. It sounds like a sub woofer at a low frequency. I hear it the most while in 4 cylinder mode. This frequency could be created in the exhaust, or driveline causing most likely the cab to vibrate. If the cabs of these trucks have a low harmonic frequency that matches a slight vibration in the truck it could amplify it resulting in us hearing and feeling it.

I've had my Sierra Crew Cab since late July and noticed the vibration shortly after purchasing . It now has 8950 miles on it and its been back to the dealer twice and they don't know what to do. I bought my truck to drive not sit at the dealership . I told them to do some research before I bring it back again . Still waiting for a call. I think its time to contact the attorney general about the lemon law.

I also have a Sierra.

 

So far the TCM and torque converter replacement seems to have solved my issues. The deal just called today to ask how it was running (bout 3 weeks and 500 miles since replacemet). The also said that GM would l like them to flush out the tranny again and check to make sure everything still looks good. Dropping it off Friday.

    • There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

    • I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip. 
    • Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
