i saw this a couple months ago. i gave the car a 2nd floor call, the car travels down from the 5th floor, but it seemed to slow down for the 2nd floor way to early. then it just slowly leveled into the 2nd floor took a while, car logged stld fault and shut down. replaced the tape guides, and reglued a couple magnets that had come loose. problem solved. if you have to redo magnets use the template
