Recall# 42190 upper control arm broke on my GMC Sierra 1500. I was driving out of a church parking lot and made a left turn on to a city street and my right front passenger tire fell off. I contacted GM warranty department and got it towed to dalton motors in marianna, ar. The technician stated that I had been in an accident. That wasn't true. He called sunrise GMC in memphis, tn off covington pike and told them all types of lies and to not fix it. I took it to sunrise on November 20, 2017 and the technician looked at it for 5 seconds and said I hit a pot hole and that he would not fix it or honor my warranty. A pot hole didn't cause this problem. I currently have a 5 year 36,000 mile warranty that covers this problem. There is also a current recall on this issue and I was not notified when I purchased the vehicle. I had to look it up on my own.

8 speed transmission bucks, hesitates, lurches forward, clunks, while in drive. The Continental tires are cupping, which GM says is characteristic of the brand. The truck vibrates while at 25mph, around 50mphm and 65-75mph. While in AWD/4WD at 30 and 50mph, the driveline makes a whining noise and vibrates sometimes.

The 2016 GMC Sierra has a constant vibration which is felt through the seats and the steering wheel. The condition is identical to those submitted for the 2014 and 2015 GMC and Chevrolet models

I purchased a new GMC Sierra from royal automotive GMC in vestavia, al on May 12, 2016. Since the time of purchase, there has been a vibration present, and noticeable at speeds above 60 mph. I have taken the vehicle in to royal three times and they have yet to remedy this issue. While obviously annoying, the issue causes me headaches, and I question whether it could lead to safety issues. I'm currently working directly with GM on the issue, but there is still no resolution.
