2009 LaCrosse will not start on first crank

Replaced the battery a few days ago with Delco replacement, terminals were heavily corroded. All cleaned up.

Now the car will not start on the first crank. Sounds strong when cranking and starter disengages ... not started. Second crank is like the starter begins to crank but won't crank. Third time is the charm and the car starts and runs. Car runs great after that.

Always place the key in the ignition and turn to on and wait 10 seconds to charge the fuel system before trying to start.

Also, there is a traction control icon on and the engine icon on at all times. Not the case before the battery replacement.
