The U.S. Consumer Product Safety Commission has issued a warning for those who own the Peloton Tread+ exercise machine after a number of incidents of small children and a pet being dragged under the treadmill.

Peloton CEO John Foley recently commented after a child died in an accident related to its treadmill, “While we are aware of only a small handful of incidents involving the Tread+ where children have been hurt, each one is devastating to all of us at Peloton, and our hearts go out to the families involved,” he said in a statement.

The Consumer Product Safety Commission is currently investigating the treadmill and has said that it knows of thirty-eight other safety incidents so far.

The investigation is attempting to determine whether the Peloton Tread+ poses serious risks to children resulting from “children becoming entrapped, pinned, and pulled under the rear roller of the product.”

Included in the announcement was a video of a child apparently being pulled underneath the treadmill while playing behind the machine with a ball while another young child was using the treadmill.

Peloton pushed back on Saturday, saying that the commission’s warning was “inaccurate and misleading.” The company said in the statement that there was no reason for consumers to refrain from using the machine and that safety instructions should always be followed.
