Message on dash said I was low on DEF, etc, etc. Went to Pilot and topped off and only took 2.4 gallons out of 5. Filled up w/ DEF 2,000 miles ago. Anyone else have this happen? Just a flukey thing w/...
Had it happen once when truck (2012 F350) was about a month old. Took it to dealer who added about a gallon of DEF as that was all it would take before overflowing. Warning indicator went off and that never happened again.
Recently got a check engine light but no DEF warning message. Took it to dealer and it was a DEF tank sensor. Replaced it and OK again.
