Kids locked in my truck, in my driveway after remote start. (reproducible) my kids got locked in my car a few weeks ago where the unlock button wasn't working, I thought it was a fluke until it happened to me again. I was getting ready to take my 15 year old son to school. I unlocked the car so he could put his stuff in, and shortly after I remote started the car. My older son was in the car at the time I remote started the car, while I continued to get my younger 4 year old ready in the house. When I came back to the car with my son, my hands were full and I asked my son to unlock the car. He pressed the unlock button and nothing happened, and the door remained locked with him inside. He could not unlock the car doors to get out! (I do have video of this and can reproduce the problem it at any time) let's understand the severity of this issue: What if he got sick in the car, or had to use the bathroom, or medical emergency" what if my son was eating breakfast and choked on something while I was inside for 5-10 minutes getting my younger son ready" [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Combo 4 pin and 7 pin trailer connection is upside down. This may result in the loss of trailer lights and brakes. With connection upside down the 7 pin door will not hold plug in tightly and cause the brake and ground pins to possible disconnect. Loosing brakes while pulling a heaving load is a serious safety issue. Plug needs to be inverted to ensure the door latch holds the plug at the high point and weight of the cord holds the plug in tightly dealer is aware of the issue and GM engineer is aware of the issue.. neither has yet to fix. Same design exists on 2013 and 2014 Silverado's 1500, 2500 and 3500.

When driving a message on my information center pops up which states that taking my eyes off the road can cause a accident, ect. This makes me take my eyes off the road to see it and again to delete it. So this is a hazzard. GM said there is nothing in the owners manual about it, and engineering thinks that it happens when I touch a button on the insturment panel when driving. But it happens to appear when im driving on the highway and have not touched any control button., this is a serious distraction. Since I cannot duplicate it because it happens at random, when it does occur again I will take a picture of it. The message will not cancel on its own and blockes everything on the message center until I manually shut it off

I purchased a brand new 2015 silveradeo on 7/24/15 and at about 700 miles or so I noticed a bad vibration as the truck was in motion, took it back to the dealer cause I was very upset it being an $56,000 truck and all. They wanted me to leave the truck overnight and did not offer any vehicle to drive so I did not leave it with them. So I took the truck to ratfield tire and had the tire's balanced, all 4 tire's were out of balance, which I paid for out of pocket myself not GM.... this didnot fix the problem of the severe vibration going down the road. I then took the truck to another dealer for the vibration, they test drove it and confirmed the vibration, did a road force balance on all 4 wheels, then replaced all tire's, this also has not fixed the problem, the truck is still vibrating, the entire seat just shakes, I am presently waiting on another appointment with dealer. The service manager told me himself after replacing all 4 tire's that it felt like a balance issue inside the motor which there is no fix, now that is crazy...I fell that this truck should be replaced or my money back entirely.the truck only has a little over 2000 miles cause it makes me sick to drive it....

I purchased a brand new 2015 Chevy Silverado and in the first week I had it, while driving, the truck just simply completely shut off. Dealer claims they have never heard of this and after keeping truck for days stated could not find any issues. About one month later remotes not working and truck warning that emergency brake is on even though it was released. Could not get to register that emergency brake was off and while driving none of the turn signals were working as to truck warning to pull over due to vehicle emergency brake was on. I have only made one payment on this new vehicle and truck has already been in shop 2X.I need your help, please as dealer not helping me and I do not feel safe in this truck. I should not have to worry about it turning of or anything else as to being a brand new vehicle. I have attempted to speak with several managers and one just stated to me" that is why you have warranty and just keep eye on it." Since all this I have searched on the internet, and discovered that this has happened with other Silverado.. ed bozart chevrolett still claims no knowledge of this. Please help me. I feel this is potential accident issue. The first issued happened while driving on craig road which could have been really bad as this is a 45 mph road, luckily it was a weekend and not busy. I don't know what else to do. Spending over $40,000 on this truck not expecting to feel unsafe while driving.

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).
