Aftermarket replacement alternators are a crap shoot as to if they will work correctly.

I'm having a similar issue with my 2009 sedan 3.8. I have replaced the alternator twice as well as my battery. Now today I'm told my starter is bad and the alternator failed AGAIN. Were you ever able to find a solution? I'm unsure what to do.

No the alternator issue persists however after having the oem one fail I went to autozone and got one I think I did 8 warranty claims before I got one that functioned properly so it's just a lottery I suppose how ever at the time of replying to you I am suffering from other issues that sound alot more expensive then an alternator lol
