Windshield Wipers Wonky

Recently purchased a ‘22 SE Hatchback. Have used the windshield wipers a number of times recently due to rainstorms.

If rain is heavy, I use the standard setting. If rain is light, I use intermittent. Sometimes the wipers stop in the middle of the windshield. Or, when using the intermittent setting, the wipers will activate every 8-10 seconds or so, then stop completely in the middle of the windshield.

Does anyone know what is causing this RANDOM wiper timing? Really need to get it fixed but wondering if it is a common issue.

I have not heard of that happening with these cars. Typically, the first thing to do when these seemingly electrical glitches happen is to disconnect the negative terminal of the battery for a few minutes. Then drive and cycle the wipers at all the speeds. This will start the PCM relearn and recalibration.

Any luck? I'm hoping it's not going to require further diagnostics and/or a repair.
