Check Charging system, SH-AWD shutoff.
Important information:
2012 Acura TL SH-AWD technology package.
My dealership is a Toyota dealership.
I can hear a clicking from the engine, I don’t know where from, it’s loud when I start the car, but once it warms up it can only be heard when the hood is open.
Initial Problem:
12/3/19 My car died about a month ago, warnings came up in this order; Check charging system, Check SH-AWD, Check TCS, then the car wouldn’t shift out of 1st, then died. I had it towed to my dealer.
Abstract:
1/18/20 got my car back, Battery and Alternator were replaced, brand new. Check Battery light comes on when I shut the car off, but that went away and all was fine for awhile.
11/23/20 heading home, got a 45 minute drive ahead of me, all freeway driving. Check charging system and Check SH-AWD warning comes on before the freeway, so I turned off extra electonics and find a spot to park and let it sit for a minute, and call my dealership. I decided to drive it to my dealership, still 40 minutes away. When I got to my dealership and shut it off, the problem went away. They looked at it and said it was a computer issue, I told them my SH-AWD shut off and my windows and wipers were lagging, it has to be more than a computer issue. They denied it could be and sent me on my way.
Current Problem:
At the beginning of my errands for the day (quarter mile from my driveway), Check charging system and check SH-AWD warnings come on. I finished my errands and brought it home.
It starts fine, message does not go away though, and I’m stuck on FWD as the AWD stays off.
Any idea what my issue could be?

It could be a bad battery cable that is corroding internally causing issues. I've seen this happen on the MDX a few times. I'd also hook up a voltmeter to your cig. outlet and see what it says while driving. It should ALWAYS be at 14.4-14.8 with the car on and around 12.1-12.6V when the car is off. Anything above or below those ranges is not good!
