What 2023 GMC Sierra 1500 owners say
Most recent owner complaints, unedited.
The bezel that attaches to the top of the grill flew off while I drove down the interstate. It went over my truck and almost hit the car behind me and in the lane next to me. The mounting points failed and most of them as still connected to the grill. The grill has some broken plastic mounting and several cracks in the grill around the connection points. I took the truck to the GMC dealership and they looked at it then told me to contact GMC. I have dashcam video (front and rear) of the part detaching and traveling back into traffic behind me.
My vehicle has now been at the dealer two times for issues with the engine. The first time they said my lifters needed to be replaced. They rebuilt the engine to replace the lifters and other engine parts. I picked the truck up and two days later I was driving home and the engine quit on me and I had to pull to the side of the road. I tried to restart the vehicle several times and then it started up, but only for one more mile and it completely went out again and would not restart. It had to be towed to Shumacher GM dealer in West Palm Beach. This definitely put my safety at risk since the truck shut down while driving. It seems that GM is having major issues with their engines. It is presently being inspected by the dealer and GM. I have not heard back of what the issue is, but I believe the engine will need to be replaced. I did not receive any warning messages or had no clue that the engine was going to shut down.
Information related to GMC 25V274 recall for 2023 GMC Sierra 1500 6.2L. Recall oil change inspection and change of oil to higher viscosity performed summer of 2025 (prior to my ownership). On May 17, 2026 the Truck lost engine power without warning and would not start again. Fortunately I was on a road and location where I could coast into a parking lot, but again the vehicle provided no advanced warning of any issue. Towed truck to dealership and determined that exact engine problem noted in recall had indeed occurred to engine. So GMC recall efforts to inspect and change oil had NO effect on the engine defect. Engine was replaced.
Grill/exterior parts flying off
For the second time within a year , I am having power steering failure. I replaced the power steering motor and eps module and it is giving me issues with turning. At start up it gives me a warning light saying service power steering and power steering assist reduced.
The shifter shorted out. This gave me one message, Service transmission right away. I drove 10miles home & scheduled service right away. The next day I started truck up and it said unable to shift soon. This is a wide known problem with the GMC Sierra. How many people have to sit on the side of the road with this known defect.
Grill trim popped off on Interstate. Cracked my window and almost caused several cars to crash.
