Weird - won't start, then does but weirdness

S0 5 of us get in the car to go to lunch today. Turn key... Nothing. Stop, think that's weird. Pull key out, pit it in & starts right up.

Go to lunch. Come out, get in turn key & again no start. Try pulling it out and trying again but no go. Hmmm....

Everyone out. Lock doors, unlock, just I get in and it starts right up. Weird?

Drive to work, drop off the harem of 4 girls I went to lunch with. Drive to local Indy. He hooks it up & checks for faults. Shows none. He turns it off & starts it multiple times. Scan shows battery is a-ok. 70% charge. (No charge which is nice!)

Go back to work. Park it. Work. Come out & it starts right up.

On way home I need gas. Stop & fill up. Get in, starts up but CCC doesn't work. AC is on but screen is black & no radio. Weird?!

Drive home, park.

Going to dinner. Starts no prob. CCC works but all radio stations have been reset.

Park, eat, get in & starts right up. CCC works, and parking distance sensors work sonically but no on screen graphics showing how close I am.

Weird stuff. Hmmm?

Possibilities.

One, your battery is failing, too old or not charging enough. If it's original, replace it. Recent, put a CTEK on it overnight for awhile. Always charge from under the hood, not directly on the battery. The electronics in these things are highly sensitive to voltage drops, and flaky responses are a know symptom of battery failure. Not convinced that load testing gets this all the time. If the battery's more than 4 years old, replace it.

Two, your key battery is slowly failing, but much less likely. Key transmits a code, if scrambled CAS will not start ("no crank, no start" condition). Try another key for awhile to see if the condition continues.

Three, your alternator is not generating a high enough voltage to charge. Less likely; you would see a charging code if it was too low.

Four, your IBS is a problem. And, finally, it's possible you have a partial-sleep condition and the battery is draining because something is not going to sleep every time you shut it off.

Did the indy do a code check. If not, get BMWhat or INPA can check your codes and battery/alternator outputs.

Look at your battery first.

He hooked it up, checked the codes. Checked the battery. Battery at 70% charge.

I'm trying a different key last night & today. The bad key or different key theory doesn't explain the other weirdness.

No, it doesn't. The symptoms you have are classic bad battery ones. How old is it?

Another thing. Check all the battery connections, both at the battery and under the hood.

Batter is from 03-2011. Replaced by previous owner at the dealer. Car had 45k on it then, has 85k now.

How long should a battery last on this car in a HOT climate like Las Vegas?

Yes he ran the codes, he checked the battery but did not load test it. I have a battery tender and can change it up over night tonight. Thinking about just replacing it tho.... Indy price to replace and register it quoted ~$275 - $300 for an interstate which doesn't sound too bad considering the battery itself is $215-$245 from interstate.

What is an IBS?

IBS is the device that monitors your battery system. It's part of the electronics on the positive post of your battery. Attachment is how it all works.

2011 is 3 years, which is pretty long in Vegas. Try the battery tender. If it helps, great -- the battery will last a lot longer. If you see that it gets better with the tender, then expect the battery is failing faster than it does in a temperate climate, and replace it in the next year.

Make sure all the connections are solid, under the hood and at the battery. There's a recall for the IBS connection ground. Check to see if it applies.

If there's no improvement, let us know.

From March 2011 to Sept. 2014 is 3.5 to be exact. :-D

Its going in tomorrow for an oil change, tranny flush and brake fluid flush. I'll have them load test it and check all the connections

Im thinking about just getting the new battery anyway just so I know it's done. I'm also going to have them check the sun roof drains to be sure a car wash doesn't drown my trunk electrics (dumb feature & problem)

Takes a relaxed hour of work to reposition the trunk electronics to the left side. DIY's on it. Did it last month for mine.

Relaxed hour... Herniated disc days that isn't gonna happen right now. ;-/.

My Indy installed a new batt today, checked the electronics under tire & bone dry. Oil chng, brake fluid flush, tranny flush. Good to go.

Go home & seat belt malfunction warning pops up. :doh

Got the wifi dongle & downloading an app. so I can read & clear the codes.

Haven't had any issues since putting in the new battery other than the passenger restraint fault. Plan to read & clear that out first.

Glad to hear it. Amazing how BMWhat makes you more comfortable with the status and condition of the car.

Weird - won't start, then does but weirdness

Haven't had the crank-no crank since replacing the battery.

My other thread has the more recent issues since.

I like the bmwhat app but it doesn't tell all the codes catches most but it'd help if it included the dates.

My tech cleared all the faults and some remained in the bmwhat app.
