I have a 05 Taurus and it has 500 miles till factory warranty runs out, it is at like 34,000 ish miles and I have had it into the dealer 3 times already, because I have to keep jump starting my car. The first time I took it in, they replaced the alt and the batt. It worked fine for a while, then I had to start jump starting it again, so I took it back in and they told me that it was the alt so they replaced it and they told me to unplug my gps and my sat radio because that was draining the battery and the alt is mainly to keep the batt charged not to charge it. So I did that, then it started to have to be jumped the last two mornings and I took it back in and they replaced the alt again and told me to unplug the gps and the sat radio, which I had been. So I took it back to work after I picked it up today, and it sat for 4 hours and when I went out to go home, I had to jump start it agin.
Should the gps and the sat radio drain the batt so much, I would think that it would be the case if it was like a 91 or something, but this is a 05, It should be able to handle two things plugged into the lighter and the extra plug in. Then I have a question, what happens if it goes out again and my car is out of warranty, shouldn't this problem still be covered under the warranty? How does that work? If anyone can help me, please let me know.
