Owner report 11636671 · 2025-01-17 (January 17, 2025)
Battery heating module failed. This resulted in small, hard to distinguish, "service vehicle" icon to appear on the dash with no further information. This warning icon first appeared during a long drive, then went away on its own and eventually came back. This failure would eventually make charging, particularly in cold weather, impossible and potentially stranding the occupants. The servicing dealership has confirmed this failure and is attempting to replace the module. However, parts for this replacement seem to be unavailable with no cu…

Owner report 11670638 · 2025-07-01 (July 1, 2025)
My 2025 GMC Denali EV has experienced repeated safety-critical issues, including severe torque pull under acceleration, making it difficult to maintain safe lane position and compromising steering control. This behavior persists even after inspection and is documented on video. The vehicle has also had repeated service brake assist faults, including one critical failure at under 6,000 miles and additional incidents that resulted in me being stranded out of state. Additionally, I have experienced ghost braking while reversing, where the vehicl…

This mirror glass is only used on the passenger mirror of the EV trucks for some unknown reason. It is completely unsafe in such a large truck without huge blind spots. Because it appears to be zoomed you can completely miss cars otherwise viewable in blind spot. This also makes setting the passenger mirror up for towing very challenging and also dangerous.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
No selected model years have a complete observation window. Choose an eligible year or a shorter window.
Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
