2014 sierra parking gear reamains in neutral

Why din’t you set the parking brake. Someone could have been hurt. You would be responsible. And you could go to prison.

That’s not the only problem you will have with your new serria. I purchased a new 2014 serria slt all terrain and my transmission clunks and up shifts and down shifts horriable. I also got the 22 inch sey wheels which the chrome is falling off and I have ordered a new set through the dealer and they opened the box and the chrome was falling off of them, so the dealer ordered another pair and guess what same problem……… So now I have to go to corporate to deal with this problem. Its always the same with GM purchase from the lowest bidder for parts!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here is a list of other problems air condition blows hot randomly for no reason for about 5 seconds, the truck has a terrible stumble at idol at traffic lights, the gas mileage is ok when I am not towing anything, the best I have gotten is 24.8 mpg highway, then try to haul two or three quads and at 60 miles an hour or more my fuel mileage goes down to 6mpg tell me that isn’t fxxxxd up…. They need to do something with the active fuel management programming because the transmission is always trying to find the right gear which in turn causes all sorts of clunking and clattering. One day I was driving it and was decelerating and I just barley touched the gas pedal and it sounded like I blew the transfer case right out of the truck, fortunately it was ok but a few more times of that happening something is going to break. The truck went in for a recall a week after I picked it up for a supposed transfer case shifting into neutral for no reason. The navigation needs to be updated it cant even find the bridge near my house and is always trying to re route me. The suspension does not have enough travel it hits the bottom out stops constantly over a railroad track near my house and my 2012 serria denali never did that. I SHOULD HAVE KEPT MY 2012 SERRIA DENALI………………………………………………………………………………………………………………………………………….. IT WAS A FAR BETTER TRUCK HANDS DOWN

RE: SUSPENSION I meant top out stops which control the suspension from traveling all the way down not the bottom out stops which stop the wheels from going all the way up and hitting your fenders.

bmfk did you by any chance forget to order the off road package? I had a 2010 that did that and when I got my 2012, the only difference was that package and it did not do that. If you put bigger wheels on the truck, it seems you must have the off road package.

Yes i have the all terrain package. Just to report some more issues, all four shocks are blown out and the two rear shocks are poring oil out of them and leaving puddles of oil every where i go,that’s what you get when you put Rancho shocks in anything. yes the truck came with them, what was GM thinking????????????????????? Oh i know find the cheapest shock on the planet and sell it to our customers…..
My drivers seat is now clunking around underneath me, just another WTF!!!!!!!!!!!!! I would understand if I had taken the truck off road that some of these issues would be happening but i have never even been hard on this truck…. GM could not get me a set of wheels that the chrome wasn’t falling off so they made me go away with making two truck payments for me. How do you like that??? Thats quality control…. So they tell me that my truck was built in USA/Detroit to be exact, but i come to find out that my truck was built in Mexico and corporate told me that they do not build GMC trucks in Mexico, but it turns out that they do………………… I wondered why my truck did not say proudly built in USA in the door Jamb……. BECAUSE IT WASNT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So there are more problems, passenger side seat belt rattles against B pillar when window is open, just another WTF, dash cluster has reset itself 2 times now and i keep loosing my best gas mileage. I have a terrible drive shaft vibration on medium to hard acceleration, truck is still stumbling in drive at traffic lights. Just going to ask if anyone has noticed there truck going sideways when driving down the road and hitting a even bump and there truck feels like its going to spin out???????????????????? Another WTF!!!!!!! They said that they put triple door seals on the truck but my drivers side door seal starts to leak around 50 MPH and up WTF!!!!!!!!!!!

Just so we all get this straight I have been a loyal GMC customer since 1988 and my first truck was a 1989 GMC 3500 crew cab dually 4 wheel drive long bed. So don’t think I am a hater…… I am so disappointed with GM and this new truck, my 1989 ran and drove better that my 2014 and that is the gods honest truth!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! GM WAKE UP AND GET RID OF THE PEOPLE THAT DESIGNED THIS NEW TRUCK ITS TERRIBLE. YOU WILL BE BACK IN BANKRUPTCY COURT AGAIN OR OUT OF BUSINESS!!!!!!!!!!!!!!!!!!!!!!!!
