    Unfortunately, I am getting some this info second hand because I was not there when it happened. We have a 2009 Pontiac G9.

    As it stands, the car is rolling down the road and the battery light is on.

    The best account I can get from my wife is the car would not start, all the lights on the car started blinking, all the way down to the lights on the steering wheel. Of course the car would not start. So she goes and gets somebody to jump start it and she drove it home. BUT the battery light is still burning.

    Are we lucky enough for this to be a battery problem, or is it the alternator, (hope to goodness not) security system?

    Actually she just pulled in the driveway and shut it off. At least the car is at home now.

    First, clean the battery posts and clamp connections then try to start it. Then test the battery.

    Sulfation of the Battery posts used to be a frequent problem in past years.

    We used to test this by turning the car ignition off and turning on the headlights. Then turn the key to start. If it is a sulfated terminal, the lights will go out

    Try the simplest things first.

    I had a very similar thing happen to my truck. Blinking dash lights is often a sign of a dying alternator.

    1. Check the battery terminals. Clean and retighten.
    2. Check the system voltage with the car running. Both battery connected and disconnected.

    Report back.

    OK.... well this is what 2nd hand info is worth... it was an orange light that's an ENGINE... not a battery. Her response was, "well it looks like a battery". Complete game changer I am thinking.

    That is the "Check Engine" light. A mechanic with the correct tool should be able to read the "code" and tell you what the problem is.

    :rofl: And women wonder why mechanics take advantage.

    Pull the code and see what it is.

    Most women should NOT be allowed to drive a car.

    This is scary stupid.

    I'm sure glad you didn't waste time trying to diagnose the battery and charger system.

    Many auto parts stores will get 'check engine' codes for free, and will tell you what they mean. I know that AutoZone does.

    Good luck. Don't let her drive the car till you know what is going on with it. If more warning lights come on, like 'low oil', she'll just keep driving it until you need a new car. :faint:

    An older(I know, not that old) car with a 'check engine' light is almost a non-issue. They are $$ generators for shops. Now if you have a red light, it can be a different story.

    Maybe get it read for free somewhere. One can't be wasting $200 every other day on unneeded repairs & expect to get ahead.

    Now that I know it is the check engine light, we can take it somewhere and get a code. The thing that really alarms me is the fact the car would not start. However, it did start back up easily when she got it home. After it was parked I got to thinking, uh oh...what if this thing has to be towed out of here. THAT is when I saw it was the check engine light was burning, NOT the battery light.

    Newer cars require a minimum voltage of 13.4v to run all the electronic crap . Anything below that it shuts down. I had a similar experience on a 92 Grand Prix with a 3.4 Quad cam v6 and mine was alternator. I had a buddy bring me a fresh charged battery. It could get me about 8-10 miles before it would die again.... Took 3 batteries to get home that day :steamed:. Replacing the Alt was a 8hr 2 case beer job.:steamed: ..... I've never hated a car so much in my life as I did that one... That car was the reason for my absolute disdain for FWD cars...:steamed:

    Bad info.

    I completely agree with NailShooter.

    Running an engine with a battery disconnected is the fastest way to do harm to the electrical system in your car/truck, up to and including 'frying' the diodes in the alternator, and/or damaging the car's computer.

    Ever heard of "Alternator Death"??

    A battery - even a 'dead one' is a ballast or 'load' on the charging system.

    Running an engine w/o the battery connected will FRY the diodes in the alternator.

    Also, giving a jump-start to another vehicle, without having the 'charging' or 'jumping' vehicle running, will cause "Alternator Death", too.

    Yup, all mechanics are dishonest and just waiting to pounce on poor, unsuspecting, women. :upeyes:

    As for the OP, get the light diagnosed. Some cars will trip the light when there has been a low voltage event, which is simple enough to clear and move to testing the charging/starting system.

    G9? I'm familiar with Pontiac's G3, G5, G6, and G8, but no G9.

    Oh yeah, good chance you just need a new battery. How old is the one in there?

    Damn! My wife's M&P Shield is in and I went out to the garage to take my 2010 Acura MDX to pick it up and it did the flashing dash light thing too! I had an alert about a month ago that the battery needed to be replaced but figured it was just operating off time because it seemed to be strong and the voltage looked fine on the gauge.

    Charging it right now at 12A and hopefully will get it started and to my buddy's tire shop where they sell Interstate batteries. Either that or have him bring it to me.

    I guess that teaches me that when the MDX tells me "Hey dip****, it's time to replace X" I should probably just do it...

    Auto Zone and Advanced Auto will do a code check for you free.

    Add: And they will test your battery and I believe the alternator free also.

    Update: Sorry yes.. it is a G6, last night in my frenzy, I used the wrong name...it is a 2009 G6.

    Fired up the car this morning... started up quickly, no check engine light. :crazy:

    Drove the car around a bit, starts up... no check engine light. Went to Autozone, they said the battery and alternator are fine...can't diagnose a check engine light that won't burn. The car has been driven all over town, shut off and started a few times, no problems, no check engine light :dunno:

    The guy at Autozone said that that usually check engine and battery are not connected, but possibly if the battery had been run down, it might trip the check engine light to say something had been wrong. It was his only guess. He said that a phone can run down a battery.

    I called her and asked her was the phone charger plugged in when she had the problem, she replied "yes, I had been using it". MAYBE, if you leave a phone on a charger for 8-9 hours, it could run the battery down? I dunno.

    Kind of odd, the car seems fine now.

    Got a new battery installed in the MDX. I was able to get enough charge in the old battery to get me to the store. Fortunately an MDX can handle having the battery disconnected for a few seconds without losing everything. All it needed was the security code and everything was pretty much there except stored GPS addresses which kinda sucks. They didn't have a cigarette plug adapter that could provide enough power because the MDX only turns on those plugs when the key is in ACC position, which means running lights and all sorts of other stuff is on too.

    So now you know, it's not critical to maintain 12V while swapping a battery on an MDX, as long as you know your security code. Apparently it uses the hard drive in the nav unit to keep settings backed up. Didn't even need to reprogram my garage door button.
