In June 2022, Nautilus recalled this T616 folding treadmill because it can start on its own, posing a fall hazard to a user. The treadmills were sold at Best Buy, Walmart and other stores nationwide and online through Nautilus and Amazon from April 2021 through November 2021. If you own this treadmill, you should immediately stop using it and contact Nautilus to receive a free USB flash drive with a software upgrade and installation instructions. Nautilus has received 21 reports of the treadmills self-starting with no injuries.
