I bought this vehicle last November from Shea. When we bought the truck we noticed the check engine light, but was told that we would have to bring it back in for inspection. The last vehicle we bought from Shea it had a 30 day return and it would fix any problems. Not so with this time. So, we purchased a Platinum warranty which was a little above $2K and we believed would cover these issues. That was not the case. We had a friend of ours who is a GM Mechanic look it over and told us that it needed a high pressure fuel pump. So when I brought the vehicle in on January 22nd I told the service person at the desk that we had a platinum warranty and told him that I had a GM technician tell me that it needed a high pressure fuel pump. After sitting for six hours he comes out and tells me that I needed a high pressure fuel pump and tells me it will cost me $1400.00+ to have it fixed and it would not be covered by my warranty. And then tells me that the work they did today would cost me $150.00. I told him when I came in what the problem was. I understand that they need to do their own diagnostics, but why didn't they tell me that the part would not be covered by the platinum warranty. We paid $23K for the truck, plus an additional $2k+ for the warranty and now an additional $1,400.00-$1,500.00 for the fuel pump. So, yes we are not happy and will give a second thought to ever using Shea again. I understand that this memo will not change things, but I want you to understand that prior to today's fiasco I have told friends that I would recommend Shea when looking for a vehicle. Now I would not recommend Shea to any of our friends. Sorely disappointed! To go along with the previous text, when I purchased the 2015 Z71 Silverado the key FOB fell apart so I purchased two (2) new ones at a cost of $225 each so that I could start my vehicle on cold winter days. So far, that was a waste of money a money also because the check engine light and the high pressure fuel pump

Truck only having 30,000 miles and garage kept has considerable rusting on frame memebers as well as cross members on the frame.. There is no paint on the frame or cross memebers just a wildly flaking black wax coating. After two years when in for service the dealer stated that this was "Normal" for this model. Two shops that have inspected the frame are conserned about the amount of rust and any towning I may do in the future. At this point I only tow a small ATV trailer during the summer months.

The contact owned a 2015 Chevrolet Silverado 1500. The contact stated while towing a trailer and driving approximately 50 MPH, the vehicle started to fishtail. There was no warning light illuminated. The contact attempted to mitigate the failure by letting up off the accelerator pedal and then gently depressing the brake pedal however, the actions failed to correct the failure and got worse. The contact lost control of the vehicle and crashed into the center median metal guard rail on the passenger’s side front and rear of the vehicle with the trailer compressed against the rear of the vehicle. The contact stated that the Anti-Sway feature failed to operate as designed. A police report was filed. There was no injury sustained. The vehicle was towed to a tow lot. The insurance company deemed the vehicle a total loss. The vehicle was not diagnosed. A dealer was not contacted. The manufacturer had not been informed of the failure.

Front suspension noise - during cold weather and when first driving within the first 1/2 mile, a loud noise comes from the front suspension after driving over a bump or speed bump. This only happened when very cold and within the first 1/2 mile. Brought the vehicle to the dealer at 35000 miles (koons chevrolet, tysons corner, va) and under warranty they re-torqued the front frame cross member and lower control arms. I actually could not believe that chevrolet and the dealer stated that was the problem. In all my years repairing cars, I have never heard of a "frame cross member" requiring re-torqueing especially on a new vehicle. If it was loose along with the lower control arms, that would indicate a serious problem. Problem was not resolved. 6 months later when cold again, brought the truck to the dealer and they now state that "the sway bar bushings required lubrication". Again, I have never heard of a rubber bushing requiring lubrication. Immediately after taking the truck from the dealer, I took pictures of the sway bar bushings sowing all the lubricant oozing out. I have addressed this issue with gm and they have been non-responsive. My concern is with all the vibrations that these trucks have reported, the life cycle of the front sway bar bushings will be reduced and could have a serious detrimental affect during a crash as the vehicle gets older. I was told there is no gm service bulletin on the issue. The dealer just wants the problem to go away and not see the truck again. Gm needs to address this issue properly from a technical point of view from their engineers.
