The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

CONDITION/CONCERN

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

RECOMMENDATION/INSTRUCTIONS

A engine run timeout feature is standard on all push button start vehicles. There are 2 different scenarios for how the feature will work.

2014 models

If the customer exits the vehicle with the fob in their possession while the engine is running and the shifter is left in park, the engine will shut off after 2.5 hours. (i.e. no fob present.)
If the customer is sitting in the vehicle with the engine running and the fob is in the vehicle, the PEPS System will reach out and look for the fob after 2.5 hours. If the fob is located, the timer will reset an additional 2.5 hours (5 hours total). Following that period, the engine will shut 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.

2015 - 2016 models

If the customer exits the vehicle with the fob in their possession while the engine is running and the shifter is in park, the engine will shut off after 1 hour. (i.e. no fob present.)
If the customer is sitting in the vehicle with the engine running and the fob is in the vehicle, the PEPS system will reach out and look for the fob after 1 hour. If the fob is located, the timer will reset an additional 1 hour (2 hours total). Following that period the engine will shut 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.
