    The Battery Is Dead and Needs Multiple Jump-Starts 2012

    Anyone know if there is a similar TSB for the ILX? My battery seems weak. It didn't start the other day in -20c, which admittedly is cold but not cold enough that it shouldn't start..

    The Battery Is Dead and Needs Multiple Jump-Starts

    SYMPTOM
    The vehicle has sat for at least two days, has a dead battery, and needs multiple jump-starts to start the engine.
    NOTE:

    A dead battery could be normal depending on the battery condition, battery age, and how long the vehicle has sat. This software update will have no effect on these conditions.
    A jump-start should only be used to get the vehicle to a service station or dealer. It should not be used to fully charge the battery.
    There are many other possible causes that a vehicle needs multiple jump starts such as a faulty alternator, a faulty or sulfated battery, a parasitic draw, or loose battery cables.
    If a battery is sulfated, the sulfate makes charging the battery more difficult. After the battery is properly charged, the effect of the sulfation is reduced so that in most cases, the battery will not need another jump start.

    PROBABLE CAUSE
    The vehicle’s battery sensor monitors battery condition and the PCM determines charging mode. Based on the sulfation of the battery and customer driving habits the PCM may not select the correct charge mode.

    VEHICLES AFFECTED

    2012 Civic Si 2-Door:
    From VIN 2HGFG4A..CH700001 thru 2HGFG4A..CH703235

    2012 Civic Si 4-Door:

    Take it to a parts store and have it tested. Texas weather is havoc on batteries.

    My batteries on my previous Si lasted about two to three yrs each, the last one I changed was an Optima yellow top that lasted exactly two yrs, but I did have a system in the car and sometimes I would play it for quite awhile off battery only so I know I shortened its life

    Changed to 0w20 Full Synthetic, unplugged the ELM327 OBD reader and haven't had a problem since. Likely more to do with the synthetic oil flowing much easier then the potential power drain of the reader..

    Stay tuned, it'll only get colder here!

    It's been -27 to -30 Celsius here the past few days. Car has started OK but it's also been mostly in the garage where it's warmer. I still think the Product Recall for the 2012 Civic charging may be an issue for the ILX as well.

    I called the local Acura dealer and they said there was no product update for the ILX. I wonder if it's the case of few ILX's compared to Civic's and they aren't aware yet?

    I have never heard of the use of synthetic oil leading to battery drain or alternator failure unless there is a pressurized oil leak aimed at the alternator

    The use of synthetic is to make it easier to turn the engine over when it's cold out. Where I live, it's -30c without wind chill right now and regular oil gets thick. Synthetic 0w20 stays more like water making it much easier to turn the engine over.

    I think this cold snap is killing alot of batteries, regardless of what type of oil one uses, that's just the nature of it, plus if your car is a not a DD or you just drive very short distances the battery will tend to die faster in this type of weather

    Mine sat for three days here in NW Indiana where it got to -20F. Cranked a little slow but caught after a couple seconds. Still running "break in" oil and it's kept in an unheated garage.
