What You Should Do
Immediately check the serpentine belt for damage or looseness.
If the belt is intact, test the battery voltage with the engine running (should be 13.5-14.5V).
If voltage is low, the alternator likely needs replacement.
Have the charging system inspected by a professional as soon as possible to avoid being stranded.
