Condition / Concern
Some customers may comment that the engine stops running after extended idle with shifter in Park.

An engine run timeout feature is standard on all push button start vehicles. There are 2 different scenarios for how the feature will work.
2015 Models Without RPO AVF will power off after 2.5 hours:
1. If the customer leaves the vehicle with the fob while the engine is running and the shifter in park it will power off after 2.5 hours. (ie no fob present.)
2. If the customer is sitting with engine running and the fob is in the vehicle after 2.5 hours the vehicle will reach out and look for the fob and if it locates it in the vehicle it will reset the timer an additional 2.5 hours (5 hours total) then the vehicle will power off.
NOTE: If at any time during the first two scenarios the vehicle shifter is removed from park, the timer will reset and start over.
This is normal operation and no repairs should be made.
