One of your axes is slipping. I assume the X (left/right) axis. I assume the wheels of the car were toward the front of the printer. If not perhaps it is the Y axis.

There are 6 (not 4!). Six (6) pulleys. When you get this tilted problem the solution is to tighten the set screws on the pulleys. Very tight. Tight enough to twist the allen wrench tool (2mm allen wrench).

Many people say they "tightened all the pullleys" but they only tighten the 4 on the long belts. You need to get the one on the motor and the other end of the short belt. Those are usually actually the only 2 that need tightening.

You should be able to get to pulleys on both motors without removing anything - push the head around with power off until the set screw is lined up and visible. Worst case you can remove the small cover held on by 2 screws that hides the motor (this is only for UM2 series) and then remove the motor completely (4 screws) and tighten that pulley very tight.
