One problem related to cruise control has been reported for the 2016 Chevrolet Volt. The most recently reported issues are listed below.
Un-commanded vehicle acceleration under full electric drive mode (twice). While driving steady around 65 mph on the freeway (no cruise control used), a slight step on the accelerator, caused the car immediately accelerated up to 88 mph (dash show large electrical draw of battery power). Stepping on the brake, using the regen paddle on the steering wheel and repeated pressing the cruise control power didn't disengage the power surge. Car would accelerate when brake pressure was lifted. After repeated hard pressing of the brake pedal, there was a "clack" sound from below the driver console and the car returned to normal. Being on the freeway, I was not able to pull over and restart/reboot the car. I continued to drive cautiously, monitoring the car and left the freeway for surface streets. Everything seemed to be okay until I came to a complete stop behind traffic. When traffic started moving again, I lightly depressed the accelerator pedal and the car began accelerating quickly on it's own. Several hard presses of the brake pedal and the car returned to normal. This second incident was not as violent and the first and there was no "clack" sound from below the driver dash as with the first. This is worrisome and cannot be related to the cruise control since is was at a stop and cc isn't supposed to engage under 25 mph. The rest of the several miles to my work was uneventful. I've contacted the dealer about the safety of driving it or having it towed. Waiting for their response. I imagine the on-board computer would've stored today's driving data.
