    hello! this is the first time ever since i purchased this car that I've had an issue with it. today, got off work for lunch and doors wouldn't unlock. i could head the unlock chime when pressing the remote, but it was really low and short. used the key to open the door, and of course car wouldn't start either. took about 10 tries and it started up by itself to READY after a few seconds of last pressing the button. car has about 175k miles, original OEM 12v battery. is that the cause? did it again a few times after throughout the day. hasn't done it last 2 times I've unlocked and started the car.

    any input would be greatly appreciated.

    to be more specific, the 12V battery is implied above, I believe. You could have it tested at a battery shop, but at over 5 years old, it is likely to be at its end of life. And you said the behavior did not occur the next two times you tried "starting" the car, so the 12V could have charged just enough to allow a normal power-up sequence. But you are driving on borrowed time, to be sure.

    I'll do my morning grumpies now:

    Who do you think is better equipped to answer that? The world wide web, or you, with the car on hand?

    If you're DIY inclined:

    Start by checking it's voltage with a multimeter, with the car off. You can do that at the jumpstart point, under the hood. Better, get something like the Solar BA5, hook up directly to the battery posts, will give you a fuller assessment of the battery's condition.

    Don't want to get into this? Then:

    Get the car to a battery retailer, they should have a pro version of the Solar BA5, will be able to assess it for you. Likely for free. Or the dealership can do similar, for a small charge.

    Google "the 12 volt side of life", for a little light reading.

    What voltage are you reading, with the car off, say measured at the jump start point?

    You can jump start it under the hood, the jump start point.

    You can open the trunk manually from the inside, there’s a black plastic cover that’s covering the lever.

    All good after a jump. Battery seems to have discharge for some reason but health test passed so just needs to be recharged completely again.

    Had to jump thru backseat since we couldn’t open the hatch..

    you may want to invest in a cheap volt meter and jump pack. once you drain these little batteries, the trouble soon begins. could be you left a light on or something.
