Problems at the pump?

OK. I have had my 2018 GC Trailhawk for a week now and have only filled up half a tank. My problem is it was a PITA to fill it because the auto fill kept cutting it off, I had to manually hold it at 60% speed for it work. I am about to head over and fill it up for the second time. Am I going to have this headache for the entire time I have this car? This is my first experience with the capless fuel tank and I am worried. Any one have this issue, or did I (hopefully) catch a bad pump at the station.....

Thanks!

Ive had this problem occasionally, Rotate the pump 180 degrees so the handle is pointing upwards, that seems to make it not cut off.

There has been a lot of discussion on the topic, you are far from being alone. Seems that it varies from pump to pump. As mention, turning the nozzle upside down can help, but I think there may be a fix/tip arround here somewhere.

I try to use the pumps that have worked well for me. Some of those auto fills do exactly the same as yours if I use them. Plus I have to make sure my gas nozzle is fully pushed in snug for it to work on most pumps. Good luck to you.

Does the GC have 2 flaps in the filler hose like my 16 Ram Diesel with the capless setup? I know that the pump nozzle has to be all the way in for it not to keep shutting off.

I have the same problem occasionally with my 2017 Overland. It only seems to happen at two of the nearly 20 pumps at the gas station I frequent. It would seem like I would remember which pumps to avoid but inevitably it seems like I end up at one of those pumps once a month...

For your fueling issues try flipping the pump nozzle upside down while you fill your tank. The capless gas tank EVAP fuel flap spring mechanisms needs to be "broken in" that's why the fuel flow keeps stopping. Inserting the nozzle upside down will extend the capless EVAP fuel flap mechanism springs further allowing fuel to flow freely. As these springs stretch with use that issue should go away.

Thanks everyone. Filled up at a different pump yesterday, no issues. I will try the upside down thing if I ever have the problem again. But at least I know it wonít happen every time!

I had this problem and took it to the dealer. They replaced a part at the top of the tank, forgot what is called and never had the problem again. It’s a common issue with the grand Cherokee I was told.

Must be fixable, I've never encountered this problem. I've filled my tank all around the Great Lakes, New England, Canada, and never had an issue with the pump shutting off before my tank filled.

My 2018 with capless fill does the same at about half the pumps I try. Like others have said if flip the nozzle upside down it will work. I just don’t like the strange look I get from some people when I do it.

Was it done as a no cost warranty repair?

My 2015 Summit has done this several times but usually only at select Costco gas pumps at the location we shop at regularly here in Redwood City, CA. I've fueled up at many other gas stations and even other Costco stores and no problems.

I've noticed usually the Costco pumps I've had issues with work better if I pull up to the pumps that are on the opposite side of the fuel filler door, and stretch the hose across the back of the vehicle. The pumps on the same side as the fuel door are where I've had issues, but again, only at select pumps at our favorite Costco store.

I didn't realize there is a possible fix for this so maybe I'll ask the service advisor at my next appointment.

I have this problem also. I took it to the dealer and was informed Jeep had issued a bulletin about the problem. They replaced the gas tank on warranty. Two fillips since the tank was replaced and still have the problem. I am to take it back when I get low on gas again.
