Some of the most common reasons for alternator failure in Hyundai Elantras in Pakistan include:

Low-quality aftermarket alternators: Often used due to availability o r cost, but many dont last in local climate.

Extreme heat: Pakistani summers can cause alternator diodes o r voltage regulators to fail prematurely.

Dust and moisture: Poor road conditions in many cities lead to dust buildup in the alternator, affecting performance.

Weak battery o r grounding issues: A bad battery can put extra load on the alternator.

Improper installation o r poor-quality wiring can also result in failed charging.

To confirm the alternator is the problem, test it with a multimeter o r ask for a diagnostic scan using an OBD-II scanner to check charging system codes.
