Robot lawnmower stops frequently with the message indicating 'Lifted' but no error code on some models.

Safety first: Turn off the mower and avoid operating it on steep or uneven terrain during diagnosis.

• Inspect lift sensor mount: Tighten any screws securing the lift sensor to the Hyundai chassis.
• Check for flex points: Look for cracks or damage in the chassis that could cause the sensor to trigger when the mower twists.
• Secure wiring: Ensure the lift sensor cable is routed and clipped so it cannot tug on the sensor when the mower moves.
• Adjust boundary: Keep the mower away from holes, roots, and steep edges where one wheel may drop suddenly.
