Summary Verdict
The 2024 GMC Sierra EV, leveraging GM’s established Ultium platform, shows strong initial promise for reliability, particularly in its electric powertrain components. The dual and tri-motor setups are expected to be robust, with no widespread issues reported at this early stage. The primary areas for potential concern lie within the adaptive air suspension system, where compressor and air spring issues can arise, and in the electrical system, specifically intermittent charging faults or infotainment glitches that may require software updates or component servicing. Overall, the electric architecture suggests a simpler mechanical design, potentially leading to fewer traditional engine and transmission-related failures. Owners should remain vigilant for any anomalies in the suspension and charging systems, but the core EV technology appears sound.
