Active Grille Shudder malfunction @ 3k miles on a 24 f150. Dealership “is out of loaners” and job will take a full week.

Check engine light came on at 3k miles, and now this continuously happens from the moment the truck is on until I turn it back off.

Dropped it off at the dealership yesterday at 7:30am, and was told I would have an update at 3pm. Fast forward today, I get a text 36hrs later saying they ordered the part and it won’t arrive until Tuesday of next week. I asked for a loaner and they said “we don’t have any.”

Is this normal? My truck is brand new and I paid for the extended warranty. I have a job that requires travel so I need a vehicle ASAP.
