Warning problems of the 2024 Hyundai Elantra

I randomly get warning lights that my camera is disabled for lane departure warning, blind spot warning, forward collision warning, lane assist warning. Each warning message I get comes one after the other stating camera disabled. After a few minutes of driving, all the orange lights disappear and it seems to reset itself to normal. This has happened on three random occassions. I took it immediately to Hyundai of bay ridge but they said they were not able to duplicate the problem. I also mentioned to them that my dashboard and infotainment system constantly dims then brightens for no reason whatsoever. Sometimes, it dims for two seconds, then goes bright again, sometimes it dims for much longer. This happens everyday and it doesnt matter if it is a bright sunny afternoon or an early morning. It constantly dims then brightens. The dealer keeps saying they can't find anything wrong because diagnostics shows everything is ok with their computer. I feel like they are simply sweeping this under the rug because it is a leased vehicle and I am concerned for my safety should I suddenly lose power.

The car has an annoying picture of a coffee cup and tells me to consider taking a break followed by annoying beeps. This announcement happens every 5-10 minutes on the expressway regardless of who drives the car and if they are staying in the lanes. Hyundai took the way to disable this out of the menu this year and all the people in the car hear is annoying and distracting beeps on trips on the expressway.

Dash lights come on randomly while driving it disables all safety features, engine ticking , randomly my driver side window goes down.
