My 2013 is right around 51K. How do dirty throttle bodies initially manifest on this car before the stalling issue? I've begun to notice a slight vibration at idle.

 

A slight vibration could be a number of things but my previous cars have all been 1 of 2 things: motor mounts or a thermostat going bad. It is usually the latter which makes the car run rich causing the vibration.

 

The car starts normally now, even after replicating the situations where it would fail to start. I think cleaning the throttle bodies and doing the idle relearn did the trick. Thanks for all the help everyone.

 

Glad to hear you've got this resolved!!

 

After several months, my issue came back yesterday and today. This afternoon that stall was followed by a service engine light. EVAP CONTROL SYSTEM PRESSURE SENSOR was replace and mapping relearn. ....

 

Thanks man.

 

See, I never had a stalling problem though, the only issue was the vehicle failing to start. Did you fix yours?

 

I'm not sure if you call it stalling, it would start and just shut off and all the dash warning lights would be on.....After the fix, it starts perfectly. Actually shifts better than before with the remapping. ..seems like mpg has improve.
Feels like a mini factory tune.
