The other day my battery light came on and shortly after my car shuddered and all dash lights came on then the car died. Towed it to the nearest shop, a Firestone. After doing a diagnostic for non start they determined that the issue was the alternator. They replaced the alternator and battery, both brand new. When I came to pick up the car it drove for about 5 minutes before the battery light came back on and I had it tested at the local AutoZone. They said the alternator wasn't charging the battery and when I brought it back to Firestone they determined the new alternator to be defective and replaced it a second time. I picked it up again today and the same issue, drove about 2 miles and battery light came back on. Is this something to be concerned about? Will it turn itself off if I drive long enough? I was worried it would die on me again so I brought it the few miles back to Firestone to leave overnight.
