I started going the Lemon Law route in my state (Georgia) and once I started asking the dealership questions regarding information needed, they mysteriously were willing to do a swap from my 2015 LT to a 2016 LTZ. There is a little vibration in the steering wheel as the truck reaches 73 mph, but after less than 10 seconds, it seems to dampen itself out and even though the speed and road conditions don't change, the vibration disappears. I will say that the 2016 that I have has restored my love for the truck.

So I've had my 2016 Silverado replacement for about a month and a half and what's weird if the vibration is kinda there. I will notice it as soon as I hit 73mph, but even keeping vehicle at that speed, it disappears within 10 seconds of starting (I mean completely disappears). My 2015 Silverado would keep on shaking at that speed until I dropped below 70mph. Don't know if that is just a sign of things to come, of if they've found a way to dampen it after it starts now. I do know my truck was built towards the end of February of this year, so there may have been an engineering change to help with the issue.

Said I would update on my story so here it is. After gathering everything to submit to the State for the Lemon Law hearing, GM agreed to buy back my truck. Turned it in today and am waiting for my new one to be done after they finish up the Android Auto update to it. Traded my Red 2015 Silverado CrewCab LT for a 2016 Tungsten Metallic Crew Cab LTZ. Test drove this one for a bit and didn't feel the vibration, so I'm hoping that 1500 miles into it there still won't be one. If it does, I may try torquing the Ubolts that I keep hearing about before going down the dealer route again. This sure is frustrating going through the process, but I'm hoping in the end it was worth it. I'll update as the miles climb to see how it's doing.

Just out of curiosity, has anyone experienced a change (for better or worse) by putting better tires on the vehicle (i.e. the Michelin's I keep hearing about)?

This one I think is normal. The radio will stay on for 15 minutes after turning off the truck unless the driver side door is opened. I don't think locking it makes a difference. All of my GM vehicles have done this in the past. Not to say the rest isn't weird, but this one I think is by design.

Mainly because every vehicle I've owned to date has been GM, including an '11 Sierra, and have loved all of them. I love this truck as well minus the vibration. So I guess you can call it loyalty, but I don't know how blind it is. Is it possible that I could get another one with a vibration, yes, but by then I'll be really good at the Lemon Law process. I've also (and correct me if I missed a post) not seen the same type of issues as being un-correctable in the '16's, not to mention I've driven '15 Sierra's and Silverado's that are at or very near the same mileage as mine that do not have the same problem. There are also some accessories I've purchased (the aforementioned tonneau cover) and a bed rug that I can move into another GM Truck instead of have to re-purchase for a different brand and throw that money away. I've also got family that works for GM, some as engineers and I can see how issues like this can come up. GM doesn't have engineers that design the whole truck, someone comes up with the design and departments design individual components. Unfortunately, sometimes when those components are combined, you get issues that come up. I also don't view it as rewarding them, like I mentioned before, it all depends on how they handle this. If they decide to make me take them to the state for a resolution, then they are out. If they offer to repurchase without any hassle, then at least they are willing to try to make it right and to me that would be commendable. There's always going to be issues, and not just with vehicles, but it's on how the manufacturer handles it that determines if I remain loyal or not.

I figured I would pile on with my story regarding the vibration with my Silverado. I have a 2015 Silverado LT with 18" Wheels. The vibration in my vehicle was noticed about a month and a half after purchase, mainly because it wasn't until after that time that I was regularly driving at freeway speeds. Like many of the other accounts posted on here, my vibration starts mainly in the steering wheel at about 45mph, then seems to die off until you hit 70mph. At 70 the vibration steadily gets worse becoming noticeable in the steering and pedals around 75mph and basically shaking the entire truck at 80. I took the truck to the dealership close to where I work they replaced two tires and balanced the other two. Of course this didn't fix the problem. Took it back a week later, another two tires, balanced the other new tires again, no change. Took it in a few weeks later, PICO meter says it's balancing, they re-balanced all 4, still no change. The dealership said they were going to try to see if they could get GM to approve a non-standard repair for the issue. The dealership wanted to remove the Goodyear Wrangler tires on the truck and replace them with Michelin, GM approved, the caveat was, they wanted me to pay the difference in cost of the tires (um, no). I didn't approve since everyone involved has verified that the vibration exists, the truck only had 2300 miles when it went in for it's first repair, so it's a warranty issue. If they though a different brand of tires would fix it, they should be paying for them. Of course, I've driven a Sierra and a F-150 with the same tires on them, and the issue didn't exist. Now, under Georgia's Lemon Law, they have three attempts and then you send them a letter requesting a final repair attempt. Sent the letter and received a call from Chevy's Customer Resolution Center. The scheduled the final repair attempt for yesterday (2/22/16) and said a GM Engineer would be onsite to resolve the issue. Left the vehicle there the whole day, and when I went to pick it up I was told that the balancing machine they were using was 1/1000th of an inch off and took the tires to another dealer with a brand new machine to re-balance the tires. They said some issues were found on that machine and corrected. They also did the PICO meter again and tried to tell me the vibration I was feeling was due to the soft tonneau cover I had on the truck buffeting in the wind (really?). So in order to humor the engineer, I drove it home with the cover rolled up, anyone want to guess the result, yep, vibration still there. So under Georgia's Lemon Law, I am mailing the request for repurchase today to Chevrolet and I guess we will see what happens. Sad part is, I still love GM Trucks, and should they agree to the repurchase without too much hassle, I plan to buy another one (granted the test drive may be more involved this time around). But with 544 pages to date of people discussing this issue, there has to be an underlying cause that needs to be addressed. But you can bet that if I end up having go to to the State run mediation, I'm going to print out all 544+ pages to take them will me to the hearing. I only feel bad for whoever gets this truck next since they won't have the benefit of the Lemon Law on their side. I'll update as this progresses. -Dennis
