I would have your alternator tested.

The warning indicates that your alternator voltage is dipping below your battery voltage.Originally Posted by 2005GrandPrix
Most likely you need a new alternator.

I get this message too... sometimes a few times a day and other times I go months without seeing it. I got my battery and alternator tested at advanced auto and they said both were fine. I'm not sure though because all the electrical of my car have randomly shut off and immediately back on while I was driving twice in the past 3 months too.

You have a short somewhere. Do you have any aux devices hooked up to the battery or fusebox?

makes nosense replaced the battery tested the alternator.. then just now the charging system failure light just came back on for a sec when i hit the high beams... makes no sense any help??

Who tested the alternator? I had three in a row that were bad. Last one tested good but my C.S light still came on. Replace it and been good ever since.

advance auto, auto zone, and few other battery shops. only happens every so often

Check all your connections.

Either somethin is wrong with the connections...alternator, or maybe a faulty dummy light?

Awesome advice and thank you. The battery is no more than 2 years old so i think im covered except it is an optima red top so would that cause any problems? Also the terminals were cleaned and tightened and corrosion inhibitor was added about 3 months ago so i will double check, you cant always trust the dealership. But as of now i havent had a repeat of the light and have no problems. i have a diagnostic program on my comp. and i ran it while i drove and nothing out of the ordinary. idk i still love my baby.

ya makes no sense only happened four times three before new battery battery was tested and came back bad so got new battery thought tht was the problem....if it was something major think the light would stay on not to sure nvr had this problem
02-18-2011
yeah everytime my alts were bad the light stayed on...Do you notice it happens when you hit a hard bump? Maybe the connection to the alt is loose.
02-18-2011
ya i dont think so...its only when use turn signal, horn or high beams. doubt tht would drain the alt for tht to come on
02-18-2011
got led lights under dash could tht be doin it? but the light only comes on when i use horn or high beams or turn singal.

merged your two threads. you dont need two in the same section...or two at all..
02-18-2011
You may wanna have your system load tested somewhere. It cost me 50 bucks at the dealership. Sounds like something is drawing too much.
02-18-2011
haha alright
02-18-2011
ya maybe ill have to check into tht...i mean is it really a big deal?? just askin u guys cuz car only got 49,xxx miles and dunno why and wht made it come on those few times.
02-18-2011
It may be worth it....sucks being stuck on the side of the road.
