2015 Altima 2.5, My car wouldnt start this morning, and I got it jumped. It then ran, and drove for 20 minutes to work. I parked it, and when I attempted to restart it right after, it would not start. I know this is a classic case of a alternator problem, but my car only has 60k miles on it, and I've read that these can go for at least 100k miles. Is it common to have a alternator problem, 60k miles?
