Vibration

[SAMANTHA11]

2014 Denali,Vibration around 80 mph. After many trips to the dealer they changed the ring and pinion and balanced all the tires. Had to have new tires and wheels installed after they got stolen,the vibration got worse. The dealership said to tires were bad, that's when I learned about road for pressure and how GM only accepts certain rating to keep the vibration as little as possible. I got a case # with GM customer service.the dealership got a field engineer to check it out, he tried to rebalance still had vibration but told me it was a acceptable level. I contacted and tried to get a buy back . After a week they told they would not buy it back and are working on a repair for the problem . So I guess we have to live with it tell they get a fix. I also was told that if you buy tires from some other place then the dealer it will get worse.
