Took my 06 5AT TL into the dealer yesterday for servicing. They noticed that the positive battery terminal had a lot of corrosion but they weren't going to replace the cable. Drove it around for the day and went to dinner. Car would not start, no power at all. Got a jump and made it over to my friends house.

Went to jump it again and I got the cables on and then the power kicked on. So it seems like the terminal is bad. The dealer quoted me $240 for the replacement. Is this legit?

 

is it loose? clean and tighten it.

You can buy new cable ends at any stereo shop or auto parts store.

Try this guy. If you dont mind installing yourself. I bet you come out cheaper than stealership.
I got one set for my 01 f-350 7.3. Im impressed.

 

$240 to replace the positive battery cable? It's listed at $35-40 on www.oemacuraparts.com, takes a minute and a half to do it yourself.

 

Ended up being a bad battery. Apparently between the test (which was good Saturday afternoon) and when I pulled into Jimmy Johns (Saturday evening) the battery decided it didn't want to hold a charge anymore. The battery was under warranty but since I didn't have any of the paperwork I had to get a new one. :/
