H3 Starting issue

[Michro]

So I have a weird issue with my h3 not starting up randomly. It happens like once every 3 or so months and I have no idea what it is. It'll sound like it's about to turn over, but never does. Just keeps making noise. Then I wait like 20 mins and it starts up just fine.. Weird. Some symptoms which may also play a part are that when I press my brakes while in park, my front/inside lights dim. In thinking maybe an alternator issue? I hope it's not too pricey a fix. On normal days, there is usually a hiccup when I first start her up in the morn.

could be bad battery connections, they have a tendency to cause starting issues. try taking the connections off, and look at them and clean the battery terminals and see if that helps.

The brake booster is electric, so an occasional dimming of lights when apply the brakes is normal for the H3 due to "fuel saving" operation of the alternator.

I agree with Kyle in that you should look at your battery cables and terminals to make sure they are in good condition and are tight on the battery.
