after driving 2019 CR-V for 20 minutes, and engine is at operating temperature, temperature gauge went to zero, then gauge started moving up and down. anybody having similar problem? What's the cause and how to correct?

Dealer, Brown's Honda City, Glen Burnie MD is clueless to solve

Cool

How is your coolant level?

This is normal. The temp gauge on your V does not monitor temps between 0-boiling. It monitors what is classified for this vehicle as a normal temp range while the motor is running. Therefore, it will fluctuate commonly, depending on factors while it is running. For example, if you come to a stop (like at a traffic light) after reaching normal operating temp, the gauge will likely drop. Once you get moving again, it will climb back up. Totally normal. The gauge will fluctuate more in cooler environments than in warm ones.

I find that running the heater will drop the gauge reading as well. Totally normal.

Dealer, Brown's Honda City, Glen Burnie Maryland, initially said that American Honda Motor Company was working on a software fix. But then Drew Greenway (410-553-8656) Asst. Service Manager at Brown's Honda City, Glen Burnie Maryland messaged me back saying "No [software] updates at this time from Honda. we [Brown's City Honda, Glen Burnie Maryland] wouldn't be notified if there is one. You [the customer] would most likely get a letter from Honda when there is an actual fix for this." (end of quote). I thought it strange that a Honda dealer would say that American Honda Motor Company would not communicate with their own dealer.
