So I have a 14 GC about 37,200 miles on it. Been in the shop three times now for the same issue while drive 75mph + and if I have a little above 1/4 of a tank the check engine comes on then my vehicle jerks and I lose acceleration then vehicle just stalls and won't turn back over , dealer brought it down to I needed new fuel filters but this has happened three times and they say the codes never are stored. Today CE came on but did not stall me just read code p1289 manifold tune valve solenoid circuit. Anybody else having this problem?

I also have a 14 GC. Mine has 101,800 miles. Two weeks ago the engine quit while traveling ~75mph and 1/4 tank of fuel. Dealer replaced two fuel pumps in fuel tank for $1,500. On Monday same thing, engine quit with 1/4 tank of fuel. Different Jeep dealer this time, he says the first dealer never fixed the problem and that I should take it back to him. I put 10 gallons of diesel in and it seems to be running fine. (both dealers said to keep the tank above 1/3rd full) During the first 100,000 miles I regularly ran the fuel close to empty without any issues. I can't help but wonder what is going on? What has changed?

All they did was change my fuel filters, I haven't had any problems since then. Did they tell you they started the vehicle right back up at the dealer? Also after the second time were you able to start the vehicle back up or anything like that or did you have to get it towed, and have you had any other problems?

It would not re-start either time, I had it towed. In both cases the dealer said the engine started after adding more fuel. I've spent $340 towing this car in January.

The tank is "saddle" shaped. At about 1/4 full it is effectively split into two separate reservoirs by a hump in the center of the tank which allow clearance for the drive shaft. There are two fuel pumps, main and auxiliary. The auxiliary pump transfers fuel from the isolated side to the main pump side. For some reason the fuel from the right side is not making it to the left side despite having replaced both pumps for $1,500. What a design! And it seems that the level sensor is on the wrong side of the tank!

So is this the reason why it's best to
Keep it filled or can be speed be a factor to where it's not transferring over to the other side

Jeepmotori,
I see you have good miles on that jeep. Did you ever do a tranny oil change and at what mileage.

I have done nothing to the transmission. Still don't have car back from third trip to dealer. FCA says I need a new fuel tank. "Syphon tube integral part of tank is what failed". I paid to have two fuel pumps replaced when the problem was a tube inside the fuel tank.
