ev indicator turns to red

[J]

sometimes the green ev indicator turns to red, it's confusing.

Some general advise....when the indicator/warning lights start blinking abnormally or throws out a warning light....go get a diagnostic scan done. This should be the first thing you do rather than try to speculate what it can be. If it came out momentarily, then you might want to wait to see it becomes frequent..but if it keeps coming up then..go get a scan done.

If hte light turns red (as opposed to green) there might be something wrong with the system...so there would be a error code recorded. Go get it checked out. Once that is determined I am sure we can all talk discuss any problems you may have with rectifying the matter.
