Why is it squeaking? L10 Ultra

Had the unit about 4 weeks.  It just started squeaking/whistling like it needs oil or something.  Super annoying as it drives around.  Help!!

I am having the same issue

Put silicon spray into the front wheel. I had the same problem and found this solution here on these forums. It worked but after a month it is starting to do it again. I will respray it the next time I clean it.
