Key symptoms of alternator issues include:

Dim o r Flickering Headlights: Due to unstable electrical output.

Battery Warning Light on Dashboard: Indicates charging system problems.

Electrical Accessories Malfunctioning: Power windows, infotainment, o r dashboard instruments may act up.

Strange Noises: A failing alternator can produce grinding o r whining sounds.

Engine Stalling o r Difficulty Starting: If the alternator isn’t charging, the car relies solely on battery power until it drains.

If you notice any of these, get your alternator inspected immediately.
