My 2005 TSX has been intermittently losing charge for about a year. Finally decided to have it fixed. The shop tried replacing the alternator with three different ones, but that didn't help. The car will charge for about twenty minutes and then stop. Alternators test okay. The mechanic disabled something in the computer that regulates alternator charge and the result was the same. He gave up, not knowing what the issue is. I would appreciate anyone's insight.
