I purchased my vehicle used on Oct 14 2016. I drove it for about 3 weeks in local traffic with speeds 60mph and below with no issues. I then went on a road trip on Nov 7 2016 where I used major interstates that required speeds between 70-75 mph. As soon as I hit the major interstates I noticed something was not right. When the vehicle was set to cruise between 70-75mph and the vehicle reduced from V8 mode to V4 mode the interior of the vehicle began to vigorously shake. The handling and wheel to pavement contact felt stable so I continued my 600 mile trip. At times the shaking conditions made me feel dizzy and somewhat nauseous. I immediately upon arrival at my destination scheduled an appointment at a certified Chevy dealer and was seen Nov 14 2016. They test drove the vehicle for about 22 miles and were able to duplicate my problem, however through troubleshooting and inspection could not find anything wrong. I called the number in the warranty manual and started a claim and their resolution was the vehicle was operating as designed, but the GM advisor did say there was a known issue? however they could not tell me why the design made the vehicle do this. To me it sounds like it is a flaw in the design and GM does not know why yet. Through further research I found multiple post and discussions with the same complaint as well as a fox news report where GM spokesman tom wilkinson stated GM knows there is a problem and GM would work with customers case by case to resolve the problem. In my case the resolution was to tell me thats what it was designed to shake. I certainly dont believe what they are telling me. After serving this country in two different combat zones to protect our freedoms its disappointing to know that GM wont stand behind their product as I have stood at the front for this country.L can provide video and dealer service documents upon request.

The sunroof exploded for no known reason. No impact of anything.

Water infiltration into the driver/passenger compartments soaking the electrical system/headliner & dripping down into the interior on at least two occasions and video taped by my wife. The 2nd occurrence was 'after' the vehicle went to the dealer to be fixed for this very issue. These instances happened during rain storms, believe once while driving & once while parked in our driveway. I am unsure of the service repair dates for these instances but believe it was in April/may/June of 2016, these service records were sent to the Minnesota attorney general in a claim I filed in June 2016, of which that claim is being addressed by paul mueller of the consumer services division. Previous to my filing with the atty gen I attempted negotiatins with GM, of which a GM case number was created. I purchased this vehicle new and after the water pouring in I'm very concerned with safety issues as I have had a Tahoe burn due to water infiltration, of which was determined by state farm insurance. I'm very concerned with safety, I'm very concerned with future costs to fix anything these occurrences have caused, and, these instances have greatly reduced resale value of this new vehicle. I want GM to either replace this vehicle, or, give me a lifetime warranty for this vehicle for as long as we own it.
