I am having issues with sensors! I can start my 2022 Murano and have the awd high temp warning come on and stay for 5 or so minutes. I also have the collision avoidance sensor come on randomly this disables cruse control but when the tecs check it is not leaving a code or so I am being told. Is anyone else having this problem and how did you resolve it?

If your AWD temp warning is coming on have it checked ASAP to avoid damage.

Have you changed the tires or had any issues with them?

If there is another dealer in your area, try them. It's pretty obvious from your photo that there is a problem even if there is not an error code (which is hard to believe...) I assume they made sure the lower center bumper area doesn't have anything blocking the triangular area )which protects the radar sensor from debris...)
The dealer rotated the tires but no issues with them and when the collision sensor went off I was on open highway with no other vehicles around. I just spoke to Nissan customer service and advised them that I would likely try another dealership as Mine thinks this is nornal.

Sounds like you may have an overheating issue or a leak around the radiator, and perhaps some escaping steam (or a bit of coolant) is obstructing the front grille camera. That might also correspond with the AWD system heating up, if there's something wrong with the engine's cooling system. I haven't inspected the setup on my 2021 yet, but perhaps a rock kicked up and struck the radiator or a cooling line, so you're getting improper cooling or a leak. However, I'd think you'd be able to spot coolant somewhere under the car. I'm wondering if a cooling defiency for the engine would trigger the AWD/CVT overheating thing to kick in, simply because the coolant or the engine block is outside of normal operating specs. As I learned with my 2003 AWD, the CVT function (e.g. torque convertor lock) is tied into the engine's cooling system, and if the coolant or engine isn't running at the correct temperature, the ECM or TCM won't allow the torque convertor to lock up. I'd really say to get the CVTz50 app and see what your deterior count is, unless Nissan already knows it.

Aside from the "AEB OFF" icon light being on, the temp gauge readout looks the same as mine. I don't see anything else that's cause for alarm. I've had that message and dummy light come on maybe six times since owning this car for a year. Snow on the badge grille, freezing rain on the badge grille, a wet leaf on the badge grilled, a beetle on the badge grille, etc. Each time, I just stopped, turned off the car, cleared the obstruction, restarted the car and everything was fine. However, I never got an AWD overheating warning

EDIT: Since the problems seemed to happen after having your tires rotated, it's possible a tech did something incorrently that damaged a cooling line or maybe cracked something or damaged a sensor when the car was (I assume) put on a lift.
I have had no issues with coolant leaks or temp problems this started before the tire rotation but I will mention this to the new shop so they can look. the awd high temp comes on when the car is first driven so

The weather was clear and 20 degrees out. the dealership told Nissan customer that the AWD high temp is normal and in the last reply I have pictures of minus 20 outside temp just warming up when the warning flashed on

You are to kind to the service department LOL.. The AWD light will come on on start up or o\up till 3 or 4 km so defiantly no a heat issue. Dilawri Group is the dealership in Regina SK. and with the pandemic they have lost some staff but still they are to have a Nissan trained Tec person on the premises!!
