My new truck vibrated after leaving the dealership when I reach 70MPH on the freeway. still does it today.

I don't trust KBB anymore as there estimates for selling to a Private party are always too close to the what the dealer trader in will be. When I sell a car on AutoTrader, I will see how much the same vehicle is advertised as used from dealers. People are willing to pay that price as they know real value of the car. KBB used to be more reliable, in my opinion, the car companies and KBB are working together. I just did KBB on my 2014 Sierra Denali with 2,000 miles on it, the estimate was $42K. give me a break. That reminds me, I need to get GM to buy this truck sooner than later.

This drives me crazy. Class Action Lawsuit time.

What is DMA?

I live in Phoenix, the temp is always around 100 plus or minus. My truck vibrated first in the morning when cold. Also vibrate on long road trip through the mountains. Basically, all the time st highway speeds. For me, the temp doesn't seem to be a factor.

This is so frustrating. I was very excited to buy my new 2014 thinking, "this truck is so badass" but everyday I'm disappointed. Anyone know a lawyer that could help us with a class action lawsuit?

Another Forum found the following: Well I got a call today from dealership and they said my differnetial gears and drive shatf were warped and they are replacing the whole thing. They said they have seen 2 others like this. Well it appears the differential gears were out of round and GM wants them to replace the complete differential. Its on order so another 3-5 days without my truck! Has anyone tried that with their dealer?

So when I am adding air to my tires that already have Nitrogen from the dealer/factory, am I changing the chemistry therefore affecting tire pressure changes with temperature changes?

My tire pressure sensors don't appear to be working right. Also, the new tire the dealer installed holds air better than the rest. Before I went on a short road trip last weekend, I decided to inflate my tire to 37 all around to see if my gas milage improves and improve the wobble as my tires always look like they never have enough air in them. 2 days after the road trip, my tires are back to 32 again. Does anyone else have a issue with their tires loosing air pressure? Also, when I use a handheld tire gauge, the pressure is 2-3lbs different than the Truck tire sensors!!!

I found another link with more alarming news. This lists all of the recalls for the GMC 2014 Sierras. Loose fitting in transmission hose, airbags that fail to fully deploy but spit out the white smoke instead, seat brackets that are not welded properly, steering locking up, etc. This link will take you to a relevant National Highway Traffic Safety Administration (NHTSA) Safety Issue page: http://www-odi.nhtsa.dot.gov/owners/SearchResultsByUrlCode.action?referenceSearch.requestId=33959&referenceSearch.urlCode=174X12GEIWY650Z

This link will show you documented issues with Transmission, truck rolling backwards while in park, lag in tranny, engine turning off while driving, truck catching fire, headlights that don't aim at the road, and more. I am now more worried than before. his link will take you to a relevant National Highway Traffic Safety Administration (NHTSA) Safety Issue page: http://www-odi.nhtsa.dot.gov/owners/SearchResultsByUrlCode.action?referenceSearch.requestId=33960&referenceSearch.urlCode=RWRYQDLMAD8ZA7E

I told the story to one of my friends, he spoke to his GM Mechanic buddy who said the issue is the transmission. But there is no fix yet. Also related to the transmission, is when I am at a full stop and give it some gas, my transmission lags and then pops into gear. So irritating, makes me want to use the Manual mode with my thumb as the shifter instead of using my AUTOMATIC TRANSMISSION!!! I suggest everyone, file a BBB complaint on your vehicle.

Does it have to be 5 attempts to fix the vibration? I thought lemon law was 3 attempts.

So in order for GM to offer me a Buy Back, do I have to contact a lawyer regarding the lemon law? Or can GM just offer a buy back? Please advise.
