Just noiticed a green discoloring on the right side of the image of my V3 Mobius with C2 lens in night recordings, anyone else have that? Is it something we have to live with, or is this something to get fixed/repaired by the seller under warrantee?

There is nothing whatsoever wrong with your camera or sensor. The green you are seeing is simply a matter of how the camera is reacting to the different color temperatures of each lighting element in the image.
Mixed color temperature lighting is a common challenge for professional photographers and cinematographers that we deal with on a regular basis.
Every type of light bulb, whether it is incandescent, fluorescent, LED, halogen, mercury vapor, xenon or whatever puts out a different color temperature of light. There is no camera in the world that can completely or perfectly handle mixed artificial lighting, especially ones with small relatively primitive sensors and DSPs like dash cams. Professional photographers have all kinds of special techniques for dealing with such situations along with expensive filters designed to control specific wavelengths, lighting gels, strobes and reflectors to handle the given situation. For example, if I go on location to shoot a typical corporate architectural job like a fancy store interior I might encounter simultaneous sunlight coming in through a large window with halogen display lighting in a showcase, incandescent luminaires and various types of fluorescent lighting in the ceiling along with god knows what other sorts of light bulbs that might turn out to be in the room like LED or krypton but I have my bag of tricks and in the end the client often asks, "How did you do that?" This is how you come to see photos in fancy magazines that don't look like they were shot with an iPhone. (or a dash cam
)
So, in your video example your headlights are putting out one color temperature while the lighting on the building is simply being perceived by the camera as "greenish" because those bulbs put out a different color temperature. There is nothing wrong and the green will go away as soon as you encounter different lighting.
Here is a different example. This is one of
@kamkar1's SG9665GC screenshots posted from another thread (or maybe it was the JooVuu-X, but in any event, not a Mobius). Notice that the beam of light pointing down onto the road surface is creating a greenish pool of light. So, this is merely an example of the same phenomenon.
I would recommend reading up a bit about how color temperature works for anyone who wants to know more about this subject.
Wikipedia has an excellent page on the subject.
Color temperature is expressed in degrees of Kelvin.
The color temperature of direct noon time daylight is around 5000 degrees Kelvin. (sort of neutral)
The color temperature of a typical incandescent standard light bulb is 24oo degrees Kelvin, (warm)
A "soft white" bulb is a bit cooler at 2700K.
The color temperature of overcast daylight is around 6500K. (cool)
The color temperature of metal halide lamps tend towards greenish when captured by film and sensor. (also cool)
The Mobius has perhaps the most ability to control White Balance and exposure than any dash cam on the market. Most people wisely leave it set to "auto" unless they have a special need but it should be understood that there is only so much the sensor/DSP can handle. "White Balance" means that the camera will try its best to manage (balance) all the color temperatures it perceives so as to render "white" as "white" (also sometimes referred to as
neutral grey) on video but under mixed artificial lighting perfection is impossible.
