Dealer just called said truck was ready to be picked up. Pico test showed nothing..200 miles they drove only felt road vibration....Getting so frustrated...BBB and GM COMPANY NEXT....I WANT OUT OF THIS BS. DONT HAVE TIME TO KEEP DOING THIS CRAP.....ITS SO MESSED UP...SO FAR, 1ST TIME REBALANCE, 2ND VISIT 4 NEW TIRES, 3RD VISIT PICO...ABOUT 15 DAYS THEY HAVE HAD MY TRUCK AND NOTHING...THEY HAVE HAD IT LONGER THAN ME....

Model Year---- 2015 Model -----------Silverado Pickup Wheelbase---- crew Engine -----------5.3L Drivetrain ------4wd Wheel Size ----- 20" Last 6 characters of VIN -----402879 problem -----vibration has reported to GM dealership---HELL YES

Well truck has been at the dealer for 8 days, no call on update so I called. They have been busy you know! Said the mechanic drove it and only felt road conditions, gonna drive it again later...so they started it on the eighth day after drop off. They have had the truck almost as many days as me since purchase. I know they will call and say its nothing we didn't feel anything. Told them last time cant test it going up and down the highway in the hill country. Will keep shifting up and down and never be in 4 mode at at constant. LAST GM EVER......

This sounds familiar.Found this post on another site ..We bought a 2015 Suburban LT in August. When we test drove the vehicle had factory 20's and the ride seemed fine but never really got it up to highway speeds. Before we left the lot we had the dealer put on Chevy Factory 22's b/c we liked the look. When we finally took it on the highway we had a horrible (whole car shaking) vibration. Had tires balanced, problem still there. Had new tires put on, vibration still there. Had tires and rims road forced balanced, vibration still there. Adjusted tire pressure, vibration still there. It seems to be coming from the rear since we feel it in the bottom of the seats. We do not feel it in the swearing wheel. We are at a loss and so is the dealer as to what it is or how to fix it. Very pissed since we spent a lot of money for the car and usually spend 10 hours plus in the car for road trips home to see family. This is not our 1st suburban and our other one drove like a dream. Starting to think we got a lemon! Wondering if anyone else with a 2015 has experienced this? Any help would be greatly appreciated! Thanks.

We need to get organized and maybe take a trip to Chevrolet and get media involved. Nothing will happen till it gets out there....

Don't get me wrong. I like Cavender, They only sell the truck and try to fix it. But when the service manager pretty much blew me off about the info I learned on the internet, I felt she knew about the issues. They and all the rest are selling a product which they know has a defect and are betting on people laying down and putting their tail between their legs. Not happening here. Don't think anyone on here has had the issue fixed by any dealership.

Mine is there now...same issues as everyone here. Same fixes offered. 4th time going..Dont hold your breath..

Vibrations issues....Just bought a 2015 Chev Silverado 4x4 crew. First took it in at about 260 miles for vibration, the dealership balanced the tires. Picked it up went home. Drove to Houston again vibration, returned to dealer. Changed 4 tires, said the others were bad. Again drove to Houston again with the vibration. Wife says its making her sick sitting in the passenger seat. Took it back to the dealer, they had a mechanic ride with me. Says he felt the vibration but its normal for these trucks. WTF Never was normal in my other vehicles. So basically left me with if he feels its normal no reason to leave it here, I must be crazy so I take the truck home. Day before Thanksgiving Im sitting by the computer and type in 2015 Chevrolet Silverado vibrations...and pop. I find this has been a issue since the end of 2013 with the 2014 models. So now Im like, damn they know there is a issue but they are still selling these trucks, screwing the consumers over. Ive seen owners have there drive shafts, rear ends, axles, shockes, lots of tires changed and nothing has worked. So today I take my truck back to Cavender Chev in Boerne, talk to my service advisor rep and let her know what I have learned on the internet, she is in disbelief, she takes me to the service manager and I relay what I have found out. Youtube, this site and others. She says she isn't worried about the other trucks or sites, just my truck. Damn she knew there was a issue too! I could read between the lines. So they are doing a pico test which Im pretty sure it wont fix it, by reading other post. The give me a 2016 Chev suburban to drive as a loaner. Guess what? Yup, vibrates at 76-78 mph. Same frame shared by both. Same 5.3, tranny, frame. Checked and couldn't find a issue with the Tahoes, so Im going on a limb here and guess its a frame issue with the vibrations. Can feel it in seat, gas peddle and steering wheel. I don't know whats going to happen but if they don't fix it Im not going to go away saying nothing I can do.
