Left drive wheel abnormal

Lidar 3000 while mowing stopped and sent a message stating the "Left drive wheel is abnormal" and shut down although, with all wheel drive, it doesn't specify which of the drive wheels is abnormal other than the left.  Could not continue mowing, could not return to the station on its own, could not move more than .3 m (1') without stopping and repeating the message (3 times).  Mower is a couple of months old, is clean, no physical damage, all screws are tight with no loose of bare wires or hardware, I can physically move the wheels with no problem.  It just won't move, won't mow, and won't return to the charging station (under its own power - I have to pick it up and carry it).  Please help.

Hello, we have received your feedback that your LiDAX Ultra 3000 AWD reports left drive‑wheel abnormality and cannot drive autonomously. Even if the wheels spin freely by hand, faults of internal motor or sensor may still trigger this alert. Please follow the troubleshooting steps below:
Power off and lift up the mower. Thoroughly clean the inner hub and axle gaps of both left‑side wheels to check for tangled grass, thin vines or fibres. Even slight tangles may trigger wheel‑related error alerts.
Check that wheels are fitted correctly without looseness. Re‑press and clip both left wheels firmly into position.
Place the mower on flat ground, reboot the whole unit, run the wheel test manually in APP and observe the working status of the two left drive wheels.
Make sure both APP and robot firmware are updated to the latest version.
If the “left drive wheel abnormal” error keeps appearing after above operations, it most likely indicates a hardware fault of the motor or wheel‑group sensor.
Please provide your device SN code, record a complete video of the error prompt, upload the problem log and keep the device online. Our technical team will conduct remote evaluation at the earliest working‑day. Please kindly understand that replies may be delayed during weekends.

I got the same message for my 2000 awd. Were they able to help you with a solution?

Received same error on my 3000 unit; please advise

It looks like this may be a bigger issue, had the same problem, they advised me to remove the battery cover and look at the wire, left side was completely twisted. Unfortunately it looks like I have to send it in for Repair. I absolutely love this mower but I am bummed about the repair process that seems to involve having to repack and ship the device. On the bright side, it looks like it’s very easy to replace the battery, so that’s definitely a plus for the design.

I’ve now experienced this issue with two mowers. I just received my second replacement, so this will be my third “new” mower.

The first mower developed problems, and the replacement began failing within days of setup. MOVA reviewed the logs from the second mower and determined that it had an MCU hardware issue requiring repair. They ultimately agreed to replace it with a brand-new unit, which I received today.


At this point, I’m concerned about the long-term reliability of the mower and would be interested to hear what other owners are experiencing.


One positive thing that really stands out from my experience is MOVA customer support. They have been excellent and have worked with me to resolve both situations.
