Summary Verdict
The 2024 GMC Hummer EV SUV, while a technological marvel, exhibits some early-adopter concerns typical of a first-generation, high-complexity vehicle. The most frequently cited issues revolve around the sophisticated electrical and suspension systems. Specifically, the adaptive air suspension can experience compressor or air spring failures, and the high-voltage electrical system may encounter charging-related errors or battery management glitches. Software issues within the infotainment system are also noted. While the electric powertrains themselves are proving robust, the integration of these advanced features requires diligent maintenance and awareness of potential electronic gremlins. Owners should budget for potential repairs related to these complex systems, especially outside of warranty.
