When driving 68mph or above the whole inside of the vehicle vibrates like a wheel is out of balance. I was told by a Chevy dealer that the drive shaft is wobbling & that's causing the vibration. And GM says it's normal.

I purchased a new 2015 Chevy Silverado 2500hd duramax crew cab lt from auto nation of pembroke pines Florida and at about a week or two of driving it I started to notice a bump/clunk from the rear of the truck just as I would come to a complete stop. It also does it just apon a strong acceleration. The vehicle had about 500 miles on it when I started to notice this. I brought the vehicle in for the first oil change at about 4K miles and told the service guy what was going on. He said they would test drive it. When I picked it up he said they could find anything wrong. I think it's the slip yoke sticking and needs to be lubricated or replaced. Some of the older truck had this issue.

This is the 10th time this has happened, and 3rd time the vehicle has entered the service center. Own a 2015 Chevy Silverado 1500 crew cab Z71, and when attempting to start the vehicle, it does not turn over, indicating that there is a theft deterrent issue. The first time the dealer was unable to replicate the issue or error code. The second time several error codes were present, which the dealer reset. This appeared to fix the issue, until 1 month later the issue presented itself again. The vehicle is currently with the dealer on it's third repair attempt. This can be very unsafe for a vehicle since in an emergency need the vehicle could be incapable of being driven.

My name is [xxx] and I am the owner of the 2015 Chevrolet Silverado lt that I leased on January 31, 2015 from huntington Chevrolet located at 370 oakwood rd, huntington station, NY 11746 (877) 415-8697. I noticed in March when the weather started getting warmer that the air conditioning was not working properly. I brought the vehicle into new rochelle Chevrolet located at 291 main St, new rochelle, NY 10801 (914) 730-9960 to have the A/C serviced, and it was discovered there was no freon. After having the freon put into the A/C system I noticed very strong fumes coming into the cabin. The vehicle was brought back into new rochelle Chevrolet twice to have the problem solved. I have the appropriate paperwork to validate the service. The 2 services at new rochelle did not fix the problem. The smell is unbearable and possibly toxic, and still coming into the cabin as of today. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
