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???

Our 2017 NV3500 had a leaking rear tail shaft seal. It also had a clunk when starting out at stop lights. Dealer replaced tail shaft seal... then the new one started leaking right away. Then they replaced the driveshaft (propeller shaft) and the tail shaft seal... both the leaking stopped and the clunk when launching at stop lights went away. They told me that the drive shaft had an imperfection on it that was tearing the seal... and ultimately causing the clunk as well.

Just noticed that the driver's side valve cover is completely caked in dirt/oil residue. The passenger side is clean as new. Any ideas where this is coming from? IMG_0620.HEIC IMG_0621.HEIC IMG_0622.HEIC IMG_0623.HEIC IMG_0624.HEIC
