The dreaded 3-year old dead battery (and why the Acura experience < its competitors)

This is not a battery problem. It's a TLX problem. The OEM battery (for anyone who has removed and looked at it) has a Johnson Controls sticker on it, who is now called Clarion, maker of Optima and someone said about 90% of all branded car batteries. I wrote about my battery failure/stalling/testing here for anyone experiencing the problem. All of our stories with the V6 SHAWD sound identical. It's the car. My guess is that with AEIS, the ECU is programmed to shut off the car with brake pressure. I found there is a pressure sensor in the brake line for SHAWD models. When released, the ECU probably triggers a relay to prompt the starter to restart the car.
I have a feeling some group of boneheads didn't program the ECU to crank the starter for long enough, because, as we all know back when cars had keys, you don't want to crank the starter long after the engine catches. But you could back then if your battery was low. My guess is Acura shorted the crank time for AIES and push button starting, which is why these cars are stalling once the battery is too cold, too low on voltage, too low of cranking amps, or all the above. I think it's a matter of time (sounds like typically between about 1.5 and 3.5 years) before most TLX owners experience this. So be aware and plan ahead.
And yes, my dealer, like the others, was less than helpful or willing to replace my battery. They threw their hands up and gave me back my keys without answering for why my car stalled... twice. And I agree that Acura created this battery testing bulletin and this one to help dealers avoid free replacements. Laughable customer service.

Given how long the 100-Month batteries last in some cars, it is an odds on bet it is the way the electronics are designed in the cars and not the batteries.

I had an issue with my battery after 2 years. Car wouldn’t start back up after auto-engine shut off at a red light. When the light turned green, I understandably got honked at several times lol. But it was scary at the time. Car luckily turned back on after several tries.
Didn't have any problems at the dealer though. They replaced the battery no questions asked.

Had my battery replaced just this past week. If the car sat for more then a day or so, it would need a boost. Replaced under warranty no questions asked. Car has 72,000kms on it.
