Chill out y'all. First and only warning

Reading through this thread (whew!), it seems that most people got their trucks stock with GoodYear tires. I wonder if the choice of tire is a regional thing or what.

I just bought a 2015(.5 I guess) GMC Sierra SLE. It is Crew Cab, 4X4, 5.3, 1K miles so far. It came stock with Bridgestone Dueler tires. I live in the Northern California area.

So far, I have not noticed any unusal vibration at any speed (knock on wood), or V8/V4 mode. I am concerned by the extent of this vibration problem though. I only came across this forum because of a reference on the Chevy Traverse forum because I also have a 2010 Traverse that just had the timing chain TSB done (that apparently is another GM horror story). It also came with Bridgestone Dueler tires.

So, I will continue to follow this thread and hope I don't end up with the vibration problem.

Has any updated to Bilstein (or any other) shocks and fixed the vibration issue?

I am curious about this as well. I read on another forum where they did upgrade to bilsteins and it fixed the vibe. Its a cheap fix for rear shocks at about $160 for the two rears.. Even if it doesn't fix it, you will still most likely have a tad bit better ride. Might be worth a shot.

I also read this on another thread.

I have stock OE shocks not ranchos. With these stiffer frames they may not do to well at dampening out all the extra frame harshness or drivetrain harmonics.

I have the random 70-75mph vibe on smooth highway and yes i did install Bilstein 4600 HD's on all 4 corners,It did'nt cure the random vibes but it rides so much better than the OEM (black) shocks and struts.No more bouncy bumps,Bilsteins were $325 and i installed them myself.The difference in dampening is night and day.Again this did NOT solve my random vibes at highway speeds,but eliminated the bouncy ride.

300ktm just posted yestetday that he put Michilen tires, Gabriel ultra shocks on the rear along with balancing the drive shaft and it was better.

Thanks zachybean for confirming also.

So it sound like properly balancing the tires and drive shaft and putting some quality tires and shocks on can make a difference in taming the vib.

I still think this is masking the origional problem though.

Editing post. I disabled AFM (v4) a few days ago and after my morning commute today I can surely confirm I still get the random skakes at higher speeds that come and go. The vibration I was feeling in the gas petal I thought at first seemed less intense with AFM off but after today I don't think it is. I also feel a steering wheel vibration more so than I did before my truck was in for service last week. Seems like maybe them remounting and rebalancing the tire could have made it worse. Somewhat frustrating. Does this amount of weights in the wheels fall into the normal range?

@ kchaggins - That is the most ridiculous comment I have ever read, If it's not your concern, why bother write 5 paragraphs.

I paid (or am paying) for a $44,000, "Professional Grade" truck, I don't expect it to drive like BMW or handle corners like a Corvette, but it should not be vibrating. As for the "mpg" , most truck owners don't buy the vehicle for gas mileage efficiencies. That is a government mandated number that the manufactures must meet. Thankfully this model can be switched to V8 mode, minus 6th gear, by method described by 'EastCoast HD' in previous post.

Thank you 'EastCoast HD' for confirming this feature, I thought that there was something wrong with the "manual mode' , as I was trying different gears to check for the vibration issues.

On a seperate note, I also noticed the "traction control" doesn't actual shut off. Or it does, but the " stability Track" stays engaged to prevent the rear end from breaking loose above ~ 30mph or from coming around, preventing the "power slide" or "donut" horse play. Again a mandated "safety" feature.

Anyway, My 1993 Ford Ranger V6 Ext Cab w/ 4" suspension lift and 33" BF Goodrich never vibrated. I was original owner and installed al the goodies after warranty expired, never had a problem. Goes to show, more technology, more bells and whistles,....more potential problems.

This vibration was noticable when I test drove the truck, but was told it was a"flat spot" on tires from sitting as it was an early model. I called bullshit, and the sales guy said it's all under warranty if there are and issues.. Now they just need to find the cure for the issues.

BTW..I wont let it bother me anymore if 'kchaggins' wants to make my payments, lol....actually it would still bother me, just slightly less

Hi Dcon,

Thanks for the comments and consideration. Since I am not an automotive technician my dissenting opinions are merely opinions and nothing more. To be clear, my comments address 2014, 2015 Silverado 1500’s with low speed v8 to v4 vibration. Keep the comments coming, I’m learning allot.

I guess this is GMs way of doing a little damage control. Lol, what a joke!!

Nope, Just calling it like I see it. Thanks!

this is such a well thought out post you made.

I invite you to come share a meal with me where I will prepare tainted meat for you to eat because by your logic, hey you cant expect the things you buy to be quality products or work properly.

so come on over and we can chat on the way to the hospital as you enjoy your food poisoning which you think is perfectly normal and reasonable to be subjected to.

geez, you have to be a paid shill GM employee trying to spread stupidity in the hopes people are high enough on drugs to swallow your horse manure to agree that their truck are supposed to shake like farm trucks driving across a corn field? tell your GM bosses there aren't enough drugs in the world to make us think these trucks are supposed to shake like that, but then GM will soon be out of the truck selling business because of their stupid handling of this. the word is out and you are becoming know as THE brand to never buy.

a quick look at this guys account page shows he joined just to make this one post and never made any other posts, GM public relations employee or just a stupid kid trying to stir up crap for sure

I can’t address all of your comments but I'm not a kid nor a GM employee but I have owned 5 GM products. Now, I am a 2014 Silverado owner. To be clear my comments concern issues pertaining to low speed 40 mph V8 toV4 transition vibrations. I stand by those comments! Raw or not I call it like I see it.

That said, my Silverado also has the dreaded high speed vibration. Today I picked up the phone and call some of my Dealer contacts and they are being made aware of this condition impacting a limited amount of 2014, 2015 Silverado’s. Procedures are in place for a fix, however, successful repairs are dependent on technician training, equipment upgrades and Dealer due-diligence apparently not consistent among dealerships. Monday my truck goes in for servicing. I will keep you informed of the results.
