Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2026 Sierra EV.
The 2026 GMC Sierra EV is a full‑size electric pickup built on the brand’s dedicated EV platform, replacing the conventional‑combustion powertrain with a battery‑driven electric motor. Its first‑year data show a modest total of four owner complaints, the lowest recorded since the model’s introduction in 2024, and the most frequent issues involve vehicle speed control and forward‑collision‑avoidance systems, while two recalls have been issued to address those concerns. This downward trend in complaints positions the 2026 model as the most reliable year in the Sierra EV’s short history, suggesting incremental improvements in both hardware and software integration.
Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2026 GMC Truck Sierra EV lead in one area — the vehicle speed control,forward collision avoidance, 1 of 4 reports (25%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the vehicle speed control,forward collision avoidance, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the vehicle speed control,forward collision avoidance pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
