2011 T&C has had a bug in it to which resets my fuel economy to the default setting of 18.7 every now and again. It usually happens after I turn the vehicle off and then back on. Today though, it did it when I was driving which was weird. The wipers turned o n and did one cycle while the message center went dark. When it turned back on it was at the main screen and the Economy reading was reset to 18.7. Any codes or fixes out there?

 

there is not a default setting of what u see its an average reading of miles and gallons of gas. Look in your owners manual it will tell u what to press on a reset. There is also avg and instant mpg readings.

 

The number is not my concern (18.7 is just what it always ends up turning to when it self resets), the fact that it gets reset on its own is, and then to have the wipers kick in when it did it the last time is not normal.

 

Looks like it is a default:

SYMPTOM/CONDITION:
The customer may complain of following conditions following a software reset of the cluster:
· Average Fuel Economy displayed in the EVIC resets to a default value of 18.7 MPG.
· Distance to Empty displayed in the EVIC is based upon a default fuel economy.
· The EVIC does not retain the unit setting (US/Metric) selected in user settings after the cluster has reset.
· Trip A/B counter displayed in the EVIC resets to zero.
· Elapsed time counter displayed in the EVIC resets to zero.

My trip info does not reset though when this bug happens.
