Why the Alternator Matters on These Platforms
Once the engine is running, the alternator powers:
-
ECU, ignition, and fuel systems
-
Electric power steering
-
Safety systems and sensors
-
Headlights, HVAC, and infotainment
-
Charging and maintaining the battery
When output drops, the battery gets forced to play alternator—briefly—and then fails. Symptoms include:
-
Repeated dead batteries
-
Flickering or dim lights
-
Charging warnings
-
Electrical glitches and no-starts
Replacing the alternator fixes the root cause, not the symptoms.

I’ve not yet installed it so this review is pretty useless. I’ll update after the fact. It did show up on time and in good condition, though.
