NHTSA Complaint #11596536 — 2023 CHEVROLET BOLT EUV

The situation occurs when using supercruise (GM’s lane centering and adaptive cruise control system). Under certain conditions with super cruise engaged and one pedal drive mode active, pressing the cancel cruise button (example: taking manual control briefly in order to allow a merging car into your lane) causes the vehicle to abruptly decelerate without the ability to override with the pedal. This uncontrollable abrupt deceleration poses a hazard to vehicles behind me. This deceleration can only really be overridden by proactively pressing on the accelerator prior to disengaging the super cruise system. I suspect this problem is caused by logic in the super cruise system which does not allow the vehicle to accelerate while the steering wheel is flashing red (such as during disengagement). Generally, removing the flashing red condition from the steering wheel requires applying torque to the steering wheel. However, this is not practical when driving straight and needing to disengage the system. The supercruise system needs to be able to safely and properly disengage at the press of a button without needing to step on the accelerator. I believe that disengaging supercruise without pressure on the accelerator pedal should lead to the car defaulting to going into maximum one pedal braking yet still being able to accelerate on command if needed. The current state of the system requires torque on the steering wheel in order to be able to accelerate out of such a situation.
