Great news. Well keep us posted so we have something to share with the dealership to troubleshoot for besides tires rebalancing and downgrading tire pressure.

Yep saw this video and my doesn’t do the same when having a bottle of water in front center console. Again it would be cool to get in a truck that also vibrates to really compare and determine ifan issue exists.

Brianibew - yes my is Duramax Denali HD which is same as Duramax 2500 HD. I did see that Sierra 1500s was the trucks mostly affected but after I watched a you tube video of a post with 1500 Sierra and bottle of water shaking in center counsel, I started getting nervous about my truck, however, I had since tested a bottle and sunglasses in my and there is nothing compared to what I saw in you tube video post. My is generally coming from rear end and I still feel just poor balancing and/or the fact that lots have posted about goodyear wranglers not being able to road force balance. I just got 1100 miles on the truck and will continue to monitor but since dealership let out some air from rear tires it definitely changed the shake/vibration and it’s less now. So I would like to find out others that may have had similar case but strictly with sierra 2500/denali HDs not 1500s. Thanks!

Well that’s great. I have Goodyear Wrangler SR-A which came stock and I haven’t heard much positive about them. I still feel that the vibration is due to balancing, I just don’t find this dealership’s techs to be as experienced as some independent tire shops that do it day-in and day-out for many years. And this forum has informed me that my stock tires are just unbalancable when it comes to road force balancing. I wish I could drive someone’s 2018 model like my just to see if anything is different/similar.

Calvic - what brand tires does yours have?

So Brianibew, you’re saying 2018 and 2019 are not the same frame? How do we tell? The trucks body is exactly the same from interior perspective. GMCJoe17 - you are right about the price aspect. However, I am now only 1000 miles on this truck and I feel I am starting to get comfortable with it. Never owned a diesel so I want to explore everything but it’s never late to go back and tell them I am still experiencing it. Maybe it’s just me too little since I went from F250 to Denali, to mention that F250 was gas, rough, bumpy, etc. and I only drove F250 for several months. I think time will tell too but based on what Brian says, I will have to comapre 2018 to 2018 in my case. Thanks all!

So went back in to dealership due to shake/vibration at 70-75mph speeds. They examined everything on truck including taking it for a ride prior and after and couldn’t duplicate what I told them my issue was. Basically they said that they let some air pressure out of rear tires to make ride more comfortable otherwise they feel truck is within “GM’s specs”. After our conversation they did tell me to continue monitoring and certainly let them know if it changes like gets worst. They did also say that I will feel little stiffer and possibly shaky/vibration at instances due to heavy duty truck especially being diesel etc... I do get that aspect and I told them interesting to learn that for high end expensive truck. I did indicate to them that when at 55-65mph speeds, the truck rides smooth no shakes or anything but as soon as I am on thruways/highways at 70+mph it tends to pick up. My next step is continue driving and monitoring to see if any changes occur but did tell them I will be taking my cousin’s 2019 year model same exact truck on same roads to see if his exhibits the same shake/vibration at any speeds. Stay tuned!

Well let me say this. My cousin and I actually purchased 2 GMC trucks together at the same time. Difference is his is 2019 but has same tires on as my. I took it for quick ride but didn’t have a chance to go 73-75 mph yet and didn’t feel vibration/shaking however I do plan to get with his on thruway just to troubleshoot and see. If his doesn’t have it, I will be back with my to ask for different set of tires or go to firestone or some other tire specialist to perform road force after explaining my experience and scapulation that dealership may not be as experienced techs.
-
Ok just did. I do feel for me it’s most likely tires. Could something happen to tires from sitting on a lot for longer period of time? My truck is 2018 and I just picked it up so it was on dealer lot probably since October 2017 not to mention it got dealer teaded to a place 2 hours away than brought back when I committed to purchase. Also, I onced owned a Toyota Tundra and had similar experience, come to find out tires were an issue. After they upgraded tires to Michelins, my shakin/vibration was gone. So I feel similar issue may be with GMC.
-
I hear you. My truck is brand new so I am little disappointed that I am experiencing this. It could very well be tires out of specs for GM road force requirement. What is meant by tires out of specs? The tires I got are goodyear wrangler SR-A highway all season. Thanks!
-
See that’s my feeling too. I hesitate to go back to dealership as I have learned that techs are mostly general and not much experienced mechanics. This is especially true with my GMC dealership as they recently just opened a new store and I see how everything is from scratch. So would you recommend going to more seasoned place, I would just have road force balancing done nothing else so from a warranty perspective it shouldn’t hurt right? Thanks!

Hi everyone. I feel like my issue is similar to K. Baker's. Once I am at 73-75mph, I tend to feel it little shake/vibration especially in rear seats and passenger seat. Just picked up the truck over 2 weeks ago, now with 650 miles on engine. Wasn’t being sure of tires and balancing. Took it back to dealership, had them road force them (stock tires/rims), kind of saw a little improvement on rear seat vibration, but still passenger seat tends to have it and now front end seems to be picking up too. I hope it’s the tires and balancing as I am not a fan of dealership’s technicians doing it. But based on what I am reading here, it could be related to trany and other things. Almost feel like I should take it to a place that specializes in tire installs, places with 30+ years of experience and seasoned technicians. I do get that it’s a machine thing, but I also feel like there is some technician experience thing to it too. And not sure if I continue sticking with the dealership or try other specialists due to warranty thing. So, any feedback/direction is much appreciated. Thanks!
