2023 GMC SIERRA 1500 Complaints

The truck jolts forward when approaching a complete stop. I have to prepare for it as I decelerate 10mph to 5mph to complete stop.

Purchased our truck 3 weeks ago. Driving this morning heard a loud pop then a min a second pop sounded like gun shot. The rear window both sides shattered. We have the rear defrost on. This is a horrible hazard.

Traveling at 70 mph on cruise control, tapped breaks to turn off, multiple warning lights flashed, vehicle lost power, and breaks with multiple messages including “Break system failure, top speed 62 mph”. I lost all breaking control on the highway and nearly crashed into other vehicles due to inability to stop. Was able to pull over, turn off vehicle, and turn back on, when the breaks were working again but the vehicles acceleration was very slow. Currently at authorized repair shop. When dropped off, there were 8-9 active codes.

TRUCK HAS DIED GOING DOWN THE ROAD AT 40MPH. ALSO HAVE ELECTRICAL ISSUES WITH RADIO..RUNNING BOARDS OPENING GOING DOWN THE ROAD. NO SOUND FROM RADIO, SIGNALS ...NO CONNECTIONS TO GOOGLE ON STAR LOST. RADIO SCREEN HALF OF SCREEN SHUTS OFF. FRONT CRASH SENSORS GO OFF WITH NOTING IN FRONT OF VEHICLE...LOSS OF CAMERAS NO CONNECTION. SOUNDS LIKE A BUG ZAPPER UNDER TRUCK. GM HAS REPROGRAMMED TRUCK NOW 3 TIMES SENT A TECH FROM FACTORY...REPLACED RADIO REPROGRAMMED ALL COMPUTERS AGAIN!! TRUCK HAS BEEN IN THE SHOP THIS TIME FOR OVER 30 DAYS WITH 6200 MILES ON IT THIS IS THE 4TH TIME SINCE I BOUGHT IN JUNE. HAVE A CASE REPRESENTATIVE FROM GM WHO WILL NOT HELP WITH ISSUES JUST KEEPS PUTTING ME OFF. HAVE VIDEOS PICTURES OF ALL THE ISSUES AND HAVE GIVEN TO DEALER AND GM

There is a clunking and popping noise on the rear suspension or spring leaf when going between 5-20 mph, there is no active recalls for this but there is a lot of people complaining about this problem and the dealer does not wants to take responsibility for this issue need help. They are forums online all over the country complaining about this issue.

I have approximately 7K miles on my truck. The problem I am reporting is the omission of a warning light or some other method of warning if the tailgate which is electronically controlled by a button center near the console, central to and just above an area provided for storage of loose personal items, and also activated by a electronic key FOB which I keep in my pocket while driving. I have had at least 8 instances of the gate opening while driving. I expect others have had the same issue. It seems GM could add a dash light or tone if this happens while vehicle is in motion.

The contact owns a 2023 GMC Sierra 1500. The contact stated while driving at an undisclosed speed, the tailgate inadvertently opened without warning. As a result of the failure, a cooler fell from the bed of the vehicle. No warning light was illuminated. The contact was concerned for his safety and the safety of other drivers while driving on the roadway. The vehicle was not diagnosed or repaired. The dealer was notified of the failure. The manufacturer was not notified of the failure. The failure mileage was approximately 2,000.

Warning light stated “Vehicle Restraint System requires Service”. Dealership looking into warning light.

electric parking brake turn on while towing behind Rv did damage to driver side ,had towed it for 340 miles before this happened it is not in my manual to disconnect the ground cable ,when I took it to dealer they gave me a paper stating I need to disconnect the ground cable after putting truck in neutral I told them GM should have put that in the manual instead of tell the dealer .I have turned a claim into GM thru bbb auto line have not heard back yet

This vehicle has a remote tail gate drop function in the center console. The button is extremely easy to accidentally activate and will activate at any time including when in gear. This creates a significant safety risk as the tailgate can accidentally open while driving at high speeds and cause any load or objects in the bed to fall out and become dangerous projectiles and/or significant roadway hazards. In addition there is no warning message to indicate that the tailgate has opened, creating further safety concerns that the vehicle operator would not realize that the tailgate has opened until they start to lose the contents of the bed. There is no vehicle setting that will disable this function, creating a situation where it is impossible for the operator to ever safely secure objects in the bed.
