I have a 2016 GMC 1500 Sierra Denali and experiencing a very scary problem that has suddenly developed with this vehicle. As I am parking or in a slow turn, the vehicle completely looses all power [engine, electronics, brakes, etc..] and the steering wheel jerks out of my hands and then a second or 2 later it comes back on and then repeated 2 more times as I was attempting to park. I had this happen while turning into a parking spot at the store. Then the next day it did it a again as I was turning into a different parking lot. I loose complete control of the vehicle. I have been lucky not to hit another vehicle, more specifically a person. I decided to park the vehicle at home and not drive it until I get GMC service to diagnose. I have an appointment at a dealership to diagnose the problem on 08-15-204 at "Chevrolet Buck GMC of Puyallup Inc.". I did some research on the internet and found a site where others have experienced the same problem. I looked for recalls yet none are concerning my vehicle, however I did find a recall# N202325410 that fits the entire issue for some earlier vehicles. Same exact problem. Something to do with the steering column electrical harness. Please advise what recourse I have?

While driving I heard -??sizzle-?? sound coming from the rear tailgate sliding window. I had my rear defroster on which I immediately turned off and the sound stopped. I got home 2 minutes later, parked the truck then an hour later when I was about to go back out to pickup my son I noticed the drivers side glass panel had shattered. I-??m now aware of this issue under Customer Satisfaction Program [XXX] -??Rear Window Defroster Thermal Event-?? and apparently this was a GM recall in Canada but not the US. I will take it to the dealership tomorrow and know they are going to say it-??s my problem but that-??s such [XXX]. Hoping they can cover this cost. I-??m listing this here as a form of documentation-??unsure if this institution can help. Thank you [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

When trying to turn, the wheel will lock and jerk in the opposite direction, at the same time my dash will say service stabilitrack and my radio screen turns black and the air conditioner/heater turns off. The car looses all power and the ability to turn the wheel in any direction

Electronics flash on and off then steering wheel jerks hard back and forth. Total loss of everything.

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)

My 2016 GMC Sierra 1500 (5.3L 8-speed). When on the highway or in the city when the truck is changing gears it has a shake almost like hitting small bumps on the side of the road. I have several friends and family members with the same model truck and have spent thousands of dollars to fix the problem by modifying the whole truck. Is there anyway a recall could be made since it has to be a huge issue with all models with the v4 mode? I brought it to a transmission shop due to GMC dealerships being booked for weeks..the receipt is attached! They said the fluid was burnt and changed it but need new torque converter!

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!!

I remote started the vehicle for about five minutes. I then got in, and turned the key on and sat in the vehicle. While it was idling, I smelled something burning. I observed a relay? on the rear window burning. I could see a flame (inside of the truck), and the truck cab filled with smoke. The relay exploded, and the rear window shattered. I shut the truck off, and the fire went out. I opened all the doors and cleared the smoke out. I believe the relay for the rear window defogger failed, causing it to overheat and start a fire. I am replacing the entire rear window. This is a fire hazzard, and a driving hazzard due to the cab filling with smoke. There was absolutely no warning or warnig lights that this was about to happen.

When trying to turn at low speed, the vehicle appear to shut off and the steering wheel violently cuts to the left and then right. I am unable to hold on to the steering wheel for fear of it breaking my wrist. The electrical system seems to completely shut off, as the panel goes black and when it returns, my settings are wiped out and the clock is reset to 12:00. When this happens, I have no control over the vehicle and it is very dangerous to people or property in its way.

Transmission shifts hard and seemingly late and early (sometimes to the extent where it feels like someone is slamming into the vehicle). This has happened since purchase in 2019 ( when I told them about it them about it they tried to tell me it was normal and acted like I was a fool), continues to get worse especially in stop and go traffic at lower speeds, but does it at all different speeds.

When turning off the road to the right or left and then again left or ight in a parking lot, vehicle loses power steering and electronic functions, resulting in no ability to steer away for other objects or pedestrians. This is a major safety concern and i have stopped driving it since it started doing this. So basically any low speed turning from Right to Left or Left to Right i lose the ability to steer. When it happened at night at eh grocery store parking lot i noticed the interior lights flickered out and then back on also.

I purchased a certified pre owned 2016 sierra slt in February and just after a month of owning it a notification started to pop up and chime on my dash stating "SERVICE TRAILER BRAKE SYSTEM". I have had my truck in the shop multiple times after to have this issue repaired and nothing has worked. They replaced the dash GM Genuine Part 84108373 break controller switch and buttons, the GM Genuine Part 23337305 trailer brake control module as well as the 7/4 pin 23404450 GM OEM Trailer Tow Receptacle. Nothing has fixed this issue! when the truck chimes I lose my trailer breaks and this is extremely dangerous hauling a camper weight 6500lbs. I also lose the ability to make phone calls, hear my blinker also the radio. This renders my truck inoperable and a danger to drive.

Rear window defrost malfunctioned during remote start and electrical fire happened inside cab and shattered window. Vehicle caught on fire due to recall on 02/26/22 at 1AM and is at McGrath GMC in Cedar Rapids, IA. They will not release the vehicle due to safety issues; rental vehicle is not being provided and they have no update on when dealer will reach out to consumer. Dealer has been contacted multiple times.

Used auto start, got in truck few minutes later and heard from rear window and a hissing and smelled electrical burning in the cab and saw smoke coming from driver side rear power sliding window. I shut off the rear window defroster and brought it to the Freehold Buick GMC dealership in NJ. They told me they tried to duplicate problem and couldn't find anything wrong. Returned to me with no corrective action taken by them. Two days later with the rear defroster on the drivers side rear window exploded and shattered while I was driving which startled me and almost caused an accident. When I returned to dealership they said it wasn't their problem as they couldn't find anything wrong and to replace it would be 1500 dollars. As of this complaint, I see there are 17 other identical complaints. There is also a customer satisfaction program (laughable) from GMC #N192265660 which identifies the problem and action the dealerships are supposed to take. But only for certain areas in the USA, Which mine did not. (purchased in PA, registered in NJ). How this is not a recall is ridiculous. It is listed as a "thermal event" Not sure how they got away with this. Its the incipient stages of a fire period. It involves a window which when starrers completes obstructs your vision and is a cut and blinding action if gets in eyes while driving. I implore the NHTSB to investigate this and order a full recall. It likely caused injuries or deaths already that are not known or reported as the reason for the accident/incidents.

Sitting at a traffic light, I could smell smoke. My Entertainment dispatch was showing a Green lightening bolt, and I knew that my phone didnt work on the center console charging pad. I lifted up the center console pad, and it was completely full of smoke. It appears that a bad design by GM has the wire running up to the wireless charging pad, in the same path as the lid hinge, and it appears that over time, the hinge has worn away all of the protective material on the wiring harness. The wiring harness is burned and charred for as long as the eye can see. Unsure what has been affected by this yet, as it goes into the shop tomorrow.

When making turns left and right at low speeds power to the truck shuts off, the steering wheel jerks left or right and warning lights and beeps are activated. The vehicle will continue through momentum, but as you try to turn the steering wheel, the wheel will jerk violently rendering the turn dangerous. This also happens when backing up and turning. The vehicle has to placed in park, ignition shut off and turned back on to continue through the turn and drive. This issue is sporadic and unpredictable. I've avoided near accidents on 5 occasions. The same symptoms occurred during the 2015 GMC Power Steering recall. I've contacted a dealership but was told it could not be fixed without my VIN number being included in the recall.

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 driving a hissing sound was heard from rear window, smoke appeared and rear window shattered. Dealer states that there was a short in the electrical system consistent with recall # N192220470 and that my vehicle does have RPO A48. My vehicle was not included in this recall due to geographical location of vehicle (Pennsylvania). This is a known potential fire risk and glass shattered into the vehicle. It should be noted that the outside temp was 60 degrees and my husband did NOT turn on defroster or open the rear window. After the smoke clear and window shattered he noticed that the defroster light was on and he shut it off manually. Had there been rear seat passengers they would have had glass on them and subjected to smoke and possible fire. God forbid a child in a rear facing child safety seat was back there, they would have been at serious risk of harm. GM has been notified and at this time is refusing to include this vehicle in their limited scope recall. I know of several others with similar stories (avail upon request), one lives in South Carolina, proving that this recall should not be limited to northern tier states. The current recall must be expanded to all 50 states asap. Lives and property are at risk.
