Control algorithm issue. Unexpected acceleration. Not confirmed by dealer. I experienced it twice. Google Gemini sems to know about this. No inspections performed. No warnings. There is a safety issue with the 2026 Chevrolet Tahoe adaptive cruise control. My observation: On a previous drive, I used the adaptive cruise control with it set at highway speed. I disengaged it as I got off the highway using the brake pedal and arrived at my destination via city streets. I turned the vehicle off, exited and locked it. Later, I re-entered the vehicle, started it and began slow speed maneuvering (<5mph) in my driveway, where in, I accidentally bumped the cruise control “Resume” switch, at which time the vehicle began to accelerate, unexpectedly. I stepped on the brake to regain control. No accident occurred. This happened a second time upon my return from the local supermarket. In my opinion, the cruise control should return to the OFF mode when the engine is turned off and not remain “On” and ready to “Resume” after the engine has been cycled. The current operating mode is unsafe.
