What causes alternator failure in Jeep Cherokees in Pakistan’s hot and dusty conditions?

My 2016 Jeep Cherokee recently suffered from an alternator failure, and the replacement cost was very high. I’ve heard that alternators don’t last long in Pakistan, especially in cities like Karachi due to heat and dust. What are the most common causes of alternator damage here? Can regular maintenance o r driving habits help prevent this in future?

Dashboard Symptoms:

Radio o r infotainment resets.

Transmission shifting oddly in some Cherokees with electronic control.

Sudden stalling while driving.

OBD-II Scan:

Some alternator o r charging faults are recorded by the ECU. A scanner may show codes like P0562 low system voltage o r P0625 generator field circuit low.
