The electrical system keeps throwing a code for short to ground as well as low voltage codes. The voltage gauge on the dash shows either over charging or under charging. The in dash radio and screen shut off and turns back on by itself while driving down the road. Occasionally while backing up or pulling forward the truck completely stalls. The transmission was subject to the shudder issue, we took it to King Cadillac in Lake City, SC for the transmission flush. After the flush we have not felt the shudder, but instead Occasionally when pulling off from a dead stop, or while crossing the very busy highway my house is on the truck looses momentum almost as if the transmission is failing to engage at all, and all of the sudden about 15 seconds later it engages and accelerates at a rapid rate. The steering is extremely loose in the tires, however the steering wheel engages after about 3/4 of an inch. I have taken it to said King Cadillac multiple times and they maintain that the steering is 100%. Although I can not let go of the steering wheel and continue straight for any length of time. I am constantly having to adjust the steering to match the pull of the vehicle to avoid changing lanes or running of the road. After 60mph the tire shake is horrible, after 70mph it is hard to keep the truck in its lane.

My truck started having a strong fuel smell by drivers door. 7/11/23 I took to the GM dealer to address strong fuel smell. The dealer at Patriot GMC said they would have to drop the tank and do smoke test to locate leak. They reported no leaks found that it looked like possible fuel on top of tank from over filling and spill. I explained I didn't overfill tank or spill any gas. Picked up truck after being told no fault found. I had to pay $539.91 to drop gas tank for testing and to check fuel pump.7/17/23 [7/11-7-17] I explained no trouble with starting or stalling with fuel pump and I just had gas smell really strong. Engine light came on when I left shop so I called dealer and explained my truck was running fine and now engine light on. I brought it back to shop after a week of testing and put back in shop on 7/17/23 They took the code and it came back as EVAP system issue. Code P0449 They said my EVAP Vent Solenoid valve circuit was open. Circuit tested terminal 1 pin loose. Terminal in connector replaced. Vent valve tested. The mechanic stated now running as designed. Multi point inspection completed. Picked up vehicle and stopped at store because I could smell gas real strong inside my cab and under hood. I contacted dealer for third time about gas smell and this time I asked for shop manager to come to vehicle so I could make sure he could smell how strong the gas smell was and now it was coming from front hood area into ac vents and into cab and it was making me nauseous and scared of fire issue. He said he would get it fixed. Received call yesterday stating that they found a small crack in fuel pump and my truck was ready for pick up. This is the same recall notice I have read about on major recall of GMC vehicles due to crack in fuel pump. My truck is a 2016-2017 but I don't see it on the recall list or have I been notified of the issue. #N192283991 Safety issue Pressure regulator cracks fuel pump. 19V837000

For over a year now multiple times while I'm driving. My vehicle's power steering will jerk/shake very abruptly, dash lights, radio, a/c & heater flicker on & off, service stabilitrak, trailer brakes etc, will pop up. then once stopped and shut off the engine the battery will act like it is dead and I will have no power to the vehicle at all. I have read the recall report & over 1 million SUV/Pickup GM vehicles (Chevy/Cadillac) manufactured through October 2015 are affected with the same issues. My 2016 GMC Sierra 1500 manufacture date on the vehicle is October 2015. I was told my VIN # was not included with the recall therefore they can't do anything to help. Even though my vehicle is experiencing exactly the same problems as the vehicles that were recalled and fixed with no out of pocket expense I am basically screwed. I also have a video of my steering wheel jerking back & forth, dash lights flickering & the engine stalling. (All in the same video)

Just purchased this used vehicle in December 2022 with high miles (202000) with a dealers extended warranty. Problem has happened twice in 2 weeks. While backing up slowly and turning my wheel the vehicle stalled and Service Stabilitrak came across the dash as it died. Then upon restarting it told me to roll drivers window down and up and the memory seat function cleared as did my clock. Like it had a battery replacement and reset to factory. Took into a GMC service shop where they found code P0700 and P0711. They were able to replicate my concern. Telling me to replace the transmission harnesses and that it is not covered under my extended warranty for powertrain. Going to cost me $1500 in repairs. After extensive research I see this is a common problem yet no recall has been issued for my 2016 GMC Sierra crew cab. Very frustrating!!

1. Loss of Power Steering - Engine shuts down - Dashboard flickers (sometimes it turns back on) 2. Loss of Power Steering & Engine shuts off while in motion - EXTREMELY DANGEROUS (Usually happens at slower speeds when turning the steering wheel) 3. Dealer has not been able to confirm the problem 4. The dealer won't look at problems unless "it" happens in their hands because the diagnostic does not show this problem. 5. No warning before this happens. No way to force the problem to happen....it just happens usually when turning wheel at slow speeds. 6. THIS IS SO DANGEROUS.... 7. The 2015 Sierra has a recall for this problem, Mine is a 2016 8. PLEASE HELP - VERY DANGEROUS

While making turns the vehicle intermittently stalls, losing all control of steering and electrical components. When it stalls there is no steering control whatsoever and the vehicle does have brakes, but slow to react.. Restart the vehicle and the computer system slowly resets. This has happened 5 times in the last2 days. Taking the vehicle to the dealership as soon as they have an opening.

The quality/precision issues I am having with my vehicle are issues that should not be happening to a $50,000 vehicle. The engine has a rough idle when it is first started up. After the vehicle warms up the rough idle gets worse. It gets even worse while I am driving it and I come to a stop sign or red light. The rough idle vibrates the entire vehicle. The rough idle is at its worse when I stop after having driven on the highway for several hours. I bought this new vehicle because my previous vehicle was totaled in an automobile accident when someone t-boned me in my 2007 gmc yukon xl. My yukon had approximately 200,000 miles and did not have a rough idle or vibrate like my 2016 sierra does. I know the technology is totally different than my 2007 but it should at least idle as good as if not better than my 2007 yukon that had 200,000 miles, but it does not. There is also a hesitation when accelerating from a stop that is getting worse with every additional mile I put on the vehicle. The hesitation is so bad at times I worry the engine is going to stall out on me. It feels/sounds like the cylinders are loading up with too much fuel and are not firing correctly. The stoichiometric ratio is not correct. At times, it feels like a miss. My fuel mileage is also decreasing. In the very beginning I was averaging around 19 miles per gallon and now I am averaging around 17 miles per gallon. I have tried different octane levels of mostly sunoco and bp fuels with no noticeable change in fuel mileage or engine performance except for the above-mentioned conditions getting worse. I am worried this rich mixture will cause premature failure of the catalytic converter and o2 sensor. I am also concerned the excess carbon could build up around the valves causing additional problems down the road after the warranty expires.
