What owners report
The vehicle exhibits vibrations that can be rather extreme at times. It seems to be most noticeable in the 70-75 MPH range but can sometimes be felt at other speeds. It feels like the vibration originates from the rear of the vehicle. Two dealerships have replaced multiple parts and have performed numerous alignments and road force balances but can not identify/remedy the problem. There are thousands of complaints on multiple online forums of this same issue for 2014-2015 GM 1500 series pickup truck. So far there has been no fix for them either. GM treats it as an annoyance in the comfort of the ride, however if they can not identify the issue how do they know it is not a safety risk.
I live in oregon, my truck that I purchased from a private owner from utah in June of 2019 had 37,300 miles today's date March 1 2020 my truck has 39,100 miles. A couple of days ago I changed to my oregon license plate. While under the truck I noticed a lot of rust on many parts of the brakes, suspension and frame especially when I lowered the spare tire which showed severe rust damage. This truck has an extreme amount of rust for a vehicle built in 2017. I consider this to be a safety hazard especially because drivers use this type of truck to haul or tow heavy loads.
Regarding 2014 GMC Sierra 6 cylinder full size pickup. Vehicle vibrates as if running over rumble strips at apx 1500 RPM. Local GM service center and GM corporate representative stated above is normal vehicle operation. Local GM service center correctly suggested that truck be driven faster or slower to prevent vibration or that vehicle be driven in 5th gear rather than overdrive 6th gear to prevent vibration. If vehicle is nor driven faster or slower to get out of vibration range, the truck will vibrate endlessly. 2014 GMC Sierra is an unsafe vehicle. Needing to speed up or slow down to prevent vibration significantly increases risk for mva. Needing to drive in 5th gear rather than 6th gear reduces gas mileage as reported to nhsta. …
I purchased new in 2014 a GMC Sierra 4x4 I take very good care of my vehicles I park inside a heated garage an wash once sometimes twice a week, including undercarriage. In January while washing undercarriage I noticed the coating on the frame is completely coming off the frame with just the spray of garden hose. I notified the service department at upstate Chevrolet in attica at my last service March 16 2015. The dealership will also verify how well I maintain my vehicles. I am now waiting for a response! In the mean time I went on line to see if anyone else is having same problem and to no surprise alot of GMC truck owners are complaining of this existing problem as well. Please contact me. My family an I have been dedicated GM owners and I am asking if this falls under the lemon law. Thank you for your concern.

The rear upper frame mount for the shock absorber failed due to corrosion. The non-paint rubberized coating placed on the entire frame of this vehicle is flaking off and exposing the bare steel to the elements. The frame of this vehicle has more rust than should be expected on a 50 year-old truck but it is less than eight years old. The truck is well taken care of and the body shows no signs of rust. The failure of the non-paint rubberized frame coating has rendered this 2005 Sierra un-drivable.
