Sudden Drop in MPG

Recommended Posts

Took my wife's 2017 NV3500 Passenger SL (V8) in for the airbag recall a few weeks ago.  Since getting it back from the dealer a few odd things have happened:

 

1. The Fuel Range prediction is wildly off, showing numbers that make no sense.

2. Her ACTUAL MPG has dropped considerably.  She drives around town with kids, and used to get 300-315 miles per tank.  Now only getting 260-270 per tank.

3. We faintly smell gasoline when the van is running, but can't find any leaks anywhere.

 

Anyone have any ideas what could cause such a sudden drop in MPG???

Did you ever figure out what was going on? Ours is doing the same thing.
