2013 Traverse stalls at stops

edited February 20 in Chevrolet
I have a 2013 Traverse, purchased 5 months ago, 89k miles, current 95k. On 700 mile trip this past weekend my Car upon arriving at destination started to stall when stopping completely, rolling stops ok. this problem continues now that i am home. I find if i shift to neutral before i come to complete stop, car does not stall. I can then shift back to D with no stall. Only time engine stalls is complete stop with trans in D, then only 50% of time.
I did start trip w full tank never got below half tank, only filled up at BP and Shell stations. I have added a fuel injector cleaner today. I checked trans fluid, was 1/2 qt low, added fluid and issue got a little better, only stalls 25-35% of stops. Battery and charging system checked out OK. Car is throwing no codes, only a dash message that reads 'check battery charging system'. That message flashes on for a few seconds and goes away, car always starts right back up.
Any one have any ideas. Wish engine or system was throwing out a code, but nothing.

    It sounds like the idle speed is too low, or erratic, or perhaps there is a heavier than usual draw on the alternator. There are lots of possibilities here, but I think, based on the symptoms you've described, I would check for vacuum leaks in hoses or in the manifold, also check the charging system for excessive draw on the alternator, also perhaps the power steering fluid level. The Idle Air Control valve is also suspect.

    Thank you for the feedback, I'll take all in consideration. I'll give update when I get a fix.

    Well I took your advice, and checked for vacuum leaks, just visual, made sure all connections were good. I also checked power steering fluid. PS was a little low, added a couple ounces ..... Stalls are no longer a problem. I did this on Thursday morning, I live in Chicago area, we had nice high pressure weather on Thur and Fri, I wanted to wait and post til today. Sat and Sun we had nasty low pressure wet cool weekend, wanted to make sure I made through a cool damp weather pattern... Traverse is running fine.
    I posted same post on another site, response from there was it could be the TCC, I googled and researched bad TCC symptoms, and that could be the problem GM seems to notorious for that.. If this starts happening again that may be the problem. I'll continue to check my trans fluid and PS fluid....
    Speaking of PS fluid... What is the correlation there??? Would have never thought that, I appreciate your response. Thank you, Thank you!!

    Well as you say, this may or may not be related, but increased friction in the pump could cause an unusual power pull on the engine. The TCC is a possibility, but usually this throws a code.

    Here's a TUTORIAL on the TCC. It doesn't sound like your problem, based on the symptoms you mentioned. I would have expected more irregularity in how the transmission behaves.

    Thank you. Great information. If I have recurring problems I will continue post.

    I searched around and found a few posts about the variable valve timing cam activator being bad OR clogged by dirt in oil.

    Since you just purchased it, you don't know the history of oil changes nor the type of oil used (should have met Dexos 1 ratings). Dirt and gunk in the oil can affect the actuators. At lower engine speed the oil pressure is lower and might drop the pressure of the oil for the activator.

    Do you know what oil is in it now? The approved Dexos oil? Is it the right weight oil?

    How does it look at how many miles. A couple of frequent synthetic Dexos oil changes might clean gunk out of actuators. I'd try 2000 to 3000 miles for first.

    IF I read the rockauto right and the posts right, there are two, for intake and for exhaust. Relatively cheap for part cost at $31 to $40 ea. for the parts.

    https://www.google.com/search?q=how+do+the+camshaft+actuators+work+on+gm+3.6+engine?&oq=how+do+the+camshaft+actuators+work+on+gm+3.6+engine?&aqs=chrome..69i57.11652j0j4&sourceid=chrome&ie=UTF-8

    A Mass Air Flow sensor might be a problem. If you're handy, you might remove and clean with a MAF spray to clean off the dirt particles on the fine, delicate wires.

    How was battery and charging tested? I'd suspect if something is allowing the idle speed to drop too low, the output from alternator drops and the system says to itself, "I have a low voltage problem. Turn on warning message."

    When you say that no warning codes were sent, was that checked with a good code reader tool such as a box store might use?
