2017 GMC Sierra: jerking or lurching

Filed Mar 7, 2020 · Driver assistance, Electrical · 70,000 miles · MO

When I'm driving at a slow speed turning the truck looses all power and the steering wheel jerks out of my hand, stabilitrak is on the display and it says roll down driver window and roll back up! It also looses all power just driving down the road no matter the speed! I have also been stopped at a stoplight and it lost all power wouldn't come back on so I had to get out pop the hood and bang I. The battery box and cables and it started again! Very scary going 75 MPH and it shuts off leaving you no steering no brakes no lights no nothing! Sometimes it says power steering failure sometimes and sometimes it says stabilitrack problem at something about towing! The brakes were also affected no brakes

Have had this into the dealer at the first oil change and complained about transmission shifting issues and it being unsafe to drive. Complaints are: hard shift, it clunks both upshifting and downshifting. Going around corners from a stop the truck will either fall on its face or jerks you violently forward. In stop or go traffic it is unsafe and happens very frequently- it randomly accelerates (jumps) quickly on its own with slight pedal pressure to the point where you constantly have to be aware and have your foot near the brake or you cause an accident by rear ending the car in front, its as if the transmission electronics get confused on how to act. Feel shuddering from truck's motor where column shift lever would shudder violently where I was afraid it would vibrate out of position. Rough idle is inconsistent at lower speed where you see tach going up and down. Starting cold you give it an easy pedal to move and wouldn't go. Trans doesn't kick in until you press harder and sometimes will lunge. Have taken into the various dealers 5-6 times, valve body change, engine motor mounts change and dealers can find no fix. Gm powertrain was even involved with no help. Complained to the gmc hotline and they said need 12,000 miles on truck before the truck knows how to drive because of the 'smart' transmission where it learns you're driving habits. Complained there are 2 of us that drive it how can it learn each individuals driving when it doesn't really know who is driving. They finally said there is nothing that can be done for it, that is the way it is. This all happens sporadically in both city low speed driving and highway driving, turning, backing up or going forward from parking. Because of these issues, didn't really drive the truck much because of the problems.

Vehicle shifts very hard in and out of 1st and 2nd gear. When starting to go at low speeds the vehicle almost stops when shifting and then jerks when it shifts. Same occurs when slowing to a stop. Vehicle was taken to the dealer and the power train was reprogrammed. The issue was a little better for a while. A few weeks later the same issue appeared again. Vehicle was taken back to the dealer in january 2020 and there is now a check engine code. Dealer plans to change 2 harnesses and change the fluid. Unfortunately the parts are on back order which kind of tells a story.

There is a shuttering in the transmission as the vehicle attempts to climb slight/steep grades at slow to medium speeds. Around 1500 RPM the vibration is sent throughout the whole vehicle. Having to increase acceleration to allow the truck to shift properly to overcome the lack of power has created a dangerous situation while navigating up snowy/ice hills. The vehicle also performs a lurching or sudden speeding up when downshifting when slowing to come to a stop. Depending on road conditions this creates a dangerous situation when approaching icy/slippery intersections.

My 2017 gmc sierra shutters and jerks when going into and out of 1st gear and going around corners when it changes gears. Especially when cold. Does not happen all the time. At times it has jerked into an intersectionand was scry. My wife will not drive this vehicle. Have had it looked at numerous times and they have changed the fluid. They tell me I have a quirky trans or it is inherent to this transmission. It is extremely frustrating and scary at times. I don't know what to do to get gm to fix it. This has been going on since I purchased the truck on 10/31/2017.
