The lifespan of a Hilux alternator varies depending on usage and driving conditions:

Typical Lifespan: 100,000 to 150,000 km 5-10 years.
Shorter Lifespan Factors:
Heavy electrical load e.g., aftermarket sound systems, extra lights.
Frequent short trips less time for proper battery charging.
Driving in extreme conditions heat, dust, water exposure.

Some Hilux owners report alternator issues earlier due to bad voltage regulators o r poor maintenance.
