SHOCKING that this car would have an electrical issue. OK, so here is what happens, and I've posted about this before, but I want more opinions. So when it gets hot out and I leave the car in the sun it just dies. I have to open the car with the key (I have the keyless entry with nav and all the bells and whistles on this car and I LOVE it except for this issue...) and get in, open and close the door a few times, then the alarm goes off, I push the power button, then the car will sometimes go right to ready and sometimes act like I'm not pushing the break for the one push, ready to go feature. As you can tell, I'm not tremendously well versed in this stuff, but I have replaced a headlight, and if I need to, I've found a junked battery for $50 and can replace it on my own, I'm just not convinced it's the battery. The car was in an accident about 9 months ago and I noticed right after I got it back from the body guy that it would sometimes erase all my presets with the radio and wipe the previous places in the nav, as well as reset the clock. All just annoying. I just have no idea why the heat plays a factor in this...that's the variable that doesn't make any sense with the battery. The year is 2006 and it is the original battery. I tested the battery with the internal battery thing with the car off and it was at 11.9 V and 14.5 V when on. Please help!
