NHTSA lists 4 safety recalls and 386 owner complaints for the 2024 GMC Sierra. Most complaints involve engine (190) and power train (74). The EPA rates it 16–25 mpg combined, and NHTSA gives it 5 stars overall.
General Motors LLC (GM) is recalling certain 2021-2024 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with a 6.2L V8 gas engine. The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.
General Motors, LLC (GM) is recalling certain 2024 Chevrolet Silverado EV and 2024-2025 GMC Sierra EV pickup trucks. The bolt that secures the rear center seat belt assembly to the seat structure may not have been properly tightened.
General Motors, LLC (GM) is recalling certain 2024 GMC Sierra EV vehicles. The front turn signal lights and parking lights may be too similar in brightness, making it difficult to see the front turn signals when they are activated. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“My 2024 L87 already had the recall done and was changed over to 0w40 oil. Driving down the road at 70 mph the engine just shut off and I had to coast to the side of the road. Checked engine codes and found p0016. Had to have the truck towed to the dealership where they replaced the engine. Clearly the 0w40 did not fix the problem.”
“My truck has experienced recurring diagnostic trouble code P244B on [XXX], [XXX], and [XXX], 2026. The latest occurrence included a check-engine warning and reduced engine power. On [XXX], at 40,833 miles, Neil Huffman Chevrolet GMC in Frankfort, Kentucky, diagnosed a damaged diesel particulate filter differential-pressure sensor connector. The dealership's written estimate states that the connector had shorted, begun melting, and had broken wires at the back of the connector. I am concerned about the cause of the electrical overheating, the possibility of additional wiring damage, and the risk of unexpected reduced engine power while driving. I have also experienced intermittent transmission-related warnings and communication fault codes, although I do not know whether these problems are related. I understand there are GM technical bulletins addressing wiring-harness damage on certain 3.0L Duramax vehicles. I am not claiming these bulletins establish the cause of my failure, but I would appreciate having my experience evaluated for a possible safety-related defect trend.”
“At approximately 2 years, 47,000 miles I received a message that I needed to service the transmission soon. I then got a message "Trailer Brakes Disabled Service Required" and another "Service Transmission Now Unable to Shift Soon". I brought the vehicle into my closest GM dealer and they said it is a faulty shift control lever. These are known to have a fault from the factory, but since I am outside of the 36,000 bumper to bumper, they will not cover the cost. It took about 2 months for the part to come in as it was on back order, and now they want $1000 to replace it.”
