Ticking sound question 2021 CX-9

Just leased a 2021 cx9 carbon edition. Has 138 miles on it. I hear a ticking sound coming into the cabin from the engine. I took the vehicle back to dealer. Service manager said it’s normal and will go away after engine warms up. Today I drove it for 45 minutes and the engine temp was up to normal range and I could still hear the ticking sound. Anyone know what is causing this?
