2024 Gmc Sierra Safety Report

The 2024 GMC Sierra, despite being a new model, has accumulated a significant 393 total complaints with NHTSA, including 5 crashes, 2 fires, and 10 injuries. This high volume of complaints for a vehicle in its first model year is concerning. A predominant pattern of issues revolves around the ENGINE, which accounts for 89 complaints, and POWER TRAIN, with 51 complaints. These often manifest as sudden engine failures, loss of power, stalling, and transmission malfunctions, some occurring at relatively low mileages (e.g., engine failure at 20,000 miles or 71,000 miles, and transmission issues leading to replacement). Several complaints describe critical safety incidents such as sudden braking at highway speeds, complete vehicle shutdowns while driving, and unexpected transmission downshifts or shifts to neutral. The lack of any recalls for a vehicle with such a high number of severe complaints, particularly concerning engine and power train, is notable. Furthermore, NHTSA has not yet released official safety ratings (Overall, Frontal, Side, Rollover) for the 2024 GMC Sierra, leaving a gap in understanding its crashworthiness performance. The overall safety picture for the 2024 GMC Sierra is concerning due to the high volume and severity of reported mechanical and electrical failures, particularly those affecting the engine and power train, which are critical for vehicle control and propulsion. The absence of safety ratings and recalls, despite numerous reports of engine failure, sudden shutdowns, and transmission issues, suggests potential unaddressed safety risks that buyers should be aware of. The data indicates a pattern of significant reliability and safety concerns that warrant close attention.

Our recommendation: Given the high volume of severe complaints, particularly concerning engine and power train failures, and the absence of safety ratings or recalls, potential buyers should exercise extreme caution and thoroughly research specific vehicle history before purchasing a 2024 GMC Sierra.
