So I just left town for a two hour trip tonight and a four hour trip in the morning,as we leave I get a" check charge system" on the DIC. The car started a slight whinning noise this morning but was unable to locate exactly from where, now im thinking my alt. It goes off at higher speeds (RPMS) and only pops on for a minute now and then. Im obviously thinking alt or battery either way I should make it to my destination tonight. Im traveling as I type so any help would be greatly appreciated. Anyone have experience with this message yet? I searched and found nothing, Thanks

Have not had that warning, but "whining" noise usually means Alternator, or specifically the "diodes". I would not count on too many miles, and a restart.

I'm thinking its a possible alternator failure since you described a whirring noise, but that doesn't discount a battery failure either. Since you're out in California and things are still open, I'd stop at an Advance or other auto parts store to have them pull the codes and check out the charging system. Since you have an '06 the battery is probably getting close to the end of its service life, we just changed the battery out in our '06 with 86,000 miles on the clock.

One caveat, GM alternators aren't made of very sturdy stuff these days and the diode packs can be killed as the alternator struggles to charge a bad battery, so you can end up with a dead alternator on top of everything else.

agree with 883. because the hhrs don't have a volt gauge you can't tell if its charging or just low charging. if its charging at a low rate you my be able to limp home if you turn off all your accesories. if you have it checked at an auto parts store and it is charging some I would buy a plug in voltage gauge so you can monitor the voltage for the trip home. good luck

Thanks guys for confirming my suspicions. I work at one of those parts places I test this kinda crap all day so I figured the old bath probably over worked the alt and both are probably in need of replacing now.
I got about an hour left of my trip and am hopping ill make it as im in some heavily wooded area in nor cal and am about to loose reception. I called the people im going to visit and they are gonna come get us if we don't make it by a certain time.
Life shouldn't be boring right, this is just another adventure!
Ill check back when I get service again, thanks all.

10-4, let us know if you made it OK.

[R CA HHR]

We made it. Ill be putting in an BAL in the morn and at least testing the battery. 96000 on the clock by the way.

[843de]

Glad you made it, with 96k on the clock you're probably due for a battery.

[Don06]

A whine sounds like bearings in the alternator or one of the pulleys on the serpentine belt. It also could be brushes in the alternator worn down to the wire leads. At 96K it's made a lot of revolutions.

Yup, alt was the issue. I tested the battery and it was good after only 5mins of charging. I installed a new alternator and am mid way on our 2 hour journey home, and with no issues. Ill put in a new battery in a couple weeks anyway as I am aware that 6 years on the stock batt is pretty good.
