Welcome! Yes, even with proper care like you mentioned on the vehicle, these emissions are prone to the issues you're experiencing. Good that you were able to get the EGR system cleaned out. My truck started with an EGR turbo code at 4K miles. I got it cleaned up and then deleted. Best thing I ever did. I suggest, if possible, to ensure your system is working good and then delete it (you will have a good system if you ever need to go back which is easy).
