During the week leading up to the alternator failing, a bunch of random lights came on in the dash. I made an appointment with the dealer ASAP, but they couldn't take me for a couple more days. The car ran ok so I figured I'd keep driving to work. I didn't know that the alternator had failed at that time, or that my battery was being drained, or that my automatic transmission needed batter power to function... fast forward a couple days and as I am driving to the dealer the shifting of the trans gets jerky. Finally my car just completely dies on the side of a busy road in rush hour traffic. Had to pay a tow truck driver $100 to tow it the last 3 miles to the dealer. They examined the car, told me it was the alternator, replaced it for $650. Apparently replacing an alternator is relatively easy and I could have done it with myself and a youtube video for less than half that price. Oh well. My dad is a mechanic and says an alternator should not fail at only 73,000 miles. I bought the car used so it was not done under warranty. I emailed Hyundai to ask them to make an exception and cover the replacement, but they politely declined.
