Recently after running my car through an automated car wash, my car makes a humming noise as if the pulley for the belts is loose or the exhaust is loose. Now, while driving my battery light comes and I am trying to figure out why
battery light, humming sound. on 2009 Chrysler Sebring
It is hard to determine what the source of the humming sound is, but if the battery light is on, I would have your battery and charging system tested. A defective Generator will make a humming noise when it is under an electrical load, likewise if the battery is not up to par. Most Auto Parts stores will perform this test for free.
