I bought my JLU last April and my engine light came on after driving it for 6300kms. I called the dealer and they suggested me to do an oil change. According to them I should do my service at around 6000. But when I picked up the Jeep they told me to come back after 10000kms. When I check the reader it was a P0456. Iā€™m so concerned about whatā€™s going on?

have you tried tightening your gas cap? Iā€™m not kidding, thatā€™s the code that would throw.

Itā€™s not a big deal, just a small leak in the Evap (gas fume vent) system. Definitely nothing to do with your oil. Did you clear the code after tightening the gas cap? Iā€™d see if that works, then just plan to take it in for a warranty check when itā€™s convenient.

Every time a thread starts with ā€œI went to the dealer the other dayā€, dealer responses read like an episode of ā€œChildren Say the Darnest Things.ā€

I wonder if dealers would be more mindful of what they tell customers, if they became aware that all their collective stupidity gets shared on the Internet.

šŸ˜‚šŸ˜‚I know! So I took it to the dealer and they said they checked it and it was all good. When they have me the work order sheet. They included a line ā€œcustomer declined maintenanceā€ like wtf! I called FCA and asked them. They were like itā€™s ok.

Yeh!! Itā€™s fixed now. But my gas mileage was like so bad when I drove home! Iā€™m really hoping it would fix it self after driving a bit and it has nothing to do
With this issue.

It was probably a head wind and a heavy foot.
