Driving in town going 20mph and the truck shut down not allowing for braking or gas and the steering locked up. Placed the vehicle in neutral, shut the truck off and turned it back. Was able to continue driving. Attempted to have the dealership we bought it from run a diagnostic and the battery was replaced but it continues to shut down at random times. Took the truck to a local auto shop after this happened again, another diagnostic was run, I am waiting the report to confirm what was done.

The vehicle consistently shuts off unexpectedly when trying to park or slow down, making it difficult to steer or control.The electric power steering stops working, especially when turning at low speeds.

- Gulfport, MS, USA

At approximately 98,000 miles, the dashboard error menu notice to service the power steering system. This vehicle has electronic power steering. While reversing at low speed, the power steering failed. I stopped the truck, turned off the engine, waited 15 seconds, and restarted the truck. The error notice reappeared and steering power returned after about 15 seconds. During that 15 seconds the steering wheel appeared to oscillate slowly about an inch, then stopped. Steering has been normal since, though the error message still appears. I know 2015 models have been recalled for this same error. I believe the recall should be expanded.

- Emery, SD, USA

While driving the power steering goes off intermittently during a low speed turn either right or left. The dash goes dark and then the steering assist warning comes on or the trailer control light comes on. This looks to be the same issue that-??s recall was issued for the year 2015.

Simply driving down the road an all your lights insode an out glitching along with steering. The steering locks up an comes back. It does not matter what you are doing. It will lock up at any giving moment. Putting you in dangerous way of others. 3months an you can barely turn it because the power steering is totally out. It now does not want to start as it needa jumped. Something electrical is draining it daily. Power steering assist light has been on.

My vehicle has on two separate occasions experienced a failure where the steering locks up, the engine shuts down, and the dash displays warnings about stabilitrac and trailer wiring. The vehicle has had random electrical glitches for some time, but they have escalated to a safety issue. In doing research, my issues sound very similar to those issues which resulted in a recall to earlier vehicles of the same generation, on report 17V-414. Googling the issue also points to insufficient grounding at the battery and / or the G218 grounding connection.

1st incident - tried to park turned in and steering went wild stability control light came on & others then truck shut down. 2nd Incident 2 days later- tried to turn off street (with grandkids in car) same thing steering about snapped my wrists off- check engine light came on and others then truck off this was all in a matter of seconds.

The trucks power source starts failing when going at about 15 mph and turning a bit, it happens when coming to a stop or when you-??re about to park. The steering wheel starts getting super stiff and all the power buttons and lights start going dim and the truck shuts off. The truck can turn on right after but at times it takes about 15 minutes for the system to reboot and then the truck will finally turn. When this happens you can-??t turn on hazard light making it a dangerous situation at night! I-??ve talked to other gmc owner with the Denali models and they have stated as well that they-??ve had the same issue occur at least once to them, this truck currently does it very often and even more in the cold weather! There has been a recall on earlier an earlier year of the same model truck but just not this one making it tedious to try to get it fixed. I-??ve took it to the mechanic and they-??ve changed the ground wires, it made the problem just happen less frequently, but it still occurs.

- Austin , TX, USA

While making a quick left hand turn at low speed, steering wheel suddenly locked, all lights and electrical went out and engine died. This left me stuck in a busy intersection with no lights. I was able to restart engine after a minute or so. Error message appeared "roll driver side window up, etc." Needless to say, no longer have confidence driving my truck not knowing when this situation may re-occur.

- Anderson Island, WA, USA

The power steering failed on three different occasions, all while making a low speed turns. Two of the times it was only a matter of a half a second or so, but the most recent time it failed and I couldn't steer my truck at all and I almost got in an accident. I needed to come to a complete stop, and put my vehicle in park, the power steering warning light had came on. After I stopped, it was another 5-10 seconds before the warning light went off and the steering returned.

- Gray, ME, USA

Randomly all electronics shut down engine stalls and lane assists wont let me turn wheel while driving in road. Normally at slow speeds. Get random warning lights that go away after seconds. When I activate a window switch all the electronics turn off and on. This happens randomly. No codes have been left to pull up when trying to solve issue. Twice with children in the car in traffic that we have almost got in a wreck due to these random issues.

- Saucier, MS, USA

A warning appeared on the display it says service power steering drive with care and I think it doesn't mean any good thing so please tell me what I need to do to drive my truck safely out of any risk. Thanks exactly I don't know what happened but that warning appears any time after turn the truck on.

- Salinas, CA, USA

Was pulling my trailer out of the water and lost all power steering, fluids full, pump working, just electrical issue. Had to drive home 20 miles without power steering, very hard to turn. They said they 'fixed' this is issue in 2015, but here I am in a 2017 with the same problem, low speed and completely lost power steering, thank goodness I wasn't pulling on to a highway or in the middle of a curve.

- Wood Village, OR, USA

The steering wheel is very hard to turn I am still using like that the truck has 40500 miles, it feels more difficult to turn at low speeds when turning on a street, driving on the freeway is not difficult to control the steering wheel.
