What owners say
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
Vehicle frequently exhibits loss of braking power. When this occurs, something sounding like the ABS systems is sometimes engaged by the vehicle and other times not. While gm claims braking performance meets federal standards, the braking power is greatly reduced when the hydraulic system is engaged and almost non-existent when neither vacuum pump nor the hydraulic system functions. Even if the braking performance meets federal standards, it creates a dangerous situation when the driver is not expecting a failure. A gmc dealership has admitted there is an issue and recommends replacing the vacuum pump but has been unable to source the parts in over two weeks and has no eta for when the part will be available. Meanwhile the braking power loss condition occurs every time the vehicle is driven. During the first instance, I was towing a travel trailer in stop and go traffic down a 7% grade. Had it not been for the trailer brakes, this could have been catastrophic. The second occurrence involved backing into my driveway and nearly causing a collision because of poor braking performance. Now that I fully aware of the issue, the vehicle is driven sparingly (only when absolutely needed) and with great care. The characterization of this issue by gm as not being a grave safety concern is inaccurate. Their inability to source parts in a timely manner is inexcusable.
While braking pedal feels like gurgling and at times complete loss of power assist making pedal very hard to depress all were in motion and intermittent making dealer diagnosis difficult and not yet able to replicate so dealer refuses to do work
While driving at normal highway speed, truck shut off except for the lights. Lost powers steering, brakes etc. Once I got the truck pulled over and stopped, attempted to restart. Was unable to do so until the 4th attempt during a 5 minutes time span. Once started, appeared to be running fine except for the mil on the dashboard which was lit.
While driving down the interstate at 70 MPH my service traction control message, service stabilitrak message, check engine light, and reduced engine power message came on. The vehicle started running very rough it would not go above 50 MPH. I drove approximately 3 miles to get off the interstate into the gas station parking lot. I turned it off for about 10 minutes when I turned it back on only the check engine light was on I took it to the shop and they ran tests and said it was the battery. Two weeks later it happened again same thing when I turned it off it worked fine after sitting for 10 minutes I got home and when I got a chance to look at it to days later the check engine light was off. I have read a lot and forums about people having the same issue but no resolution truly being found. This is a 2011 gmc sierra 1500 with the all-terrain package and only has about 60,000 miles on it it gets oil changes regularly. This really makes me think this is something gm should look into.
The tbs goes out. Putting the truck into reduced power. I was going 65 MPH and the truck slowed down to 15 MPH on the freeway. Lose all breaks control , ABS goes out to. Almost have been due to gm
Tl* the contact owns a 2012 gmc sierra. The contact stated that the vehicle experienced a loss of power which resulted in a front end collision with a guardrail.

The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. A police report was filed. There were no injuries. The manufacturer was not made aware of the failure. The failure mileage was approximately 75,000.
Issues with emissions switch. Check engine light will not go off. Also 3 and 4th gear are completely gone out. I do not tow or have had anything even remotely heavy in this truck. It's a 2005 gmc sierra with only 78,480 miles on it. I am not the only one having issues with this 4 speed transmission. It is not heavy duty enough for this size truck. Gm needs to recall all of these transmissions. When it first started slipping I lost all power going down the road at about 55mph. The vehicle that was behind me slammed on his brakes to avoid hitting me. This problem with the transmission is going to kill someone.
