Stalling on other Gladiator years
No other Gladiator model year has enough reports of stalling for a sheet of its own. See every Gladiator year.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the battery (4 reports) and the throttle body (3 reports).

What owners wrote
“Every time I fill up my gas tank, the fuel doesnât shut off in time from the pump and gas comes backward up the filler neck, onto the side of my jeep.”

“Gas "burps" back out when filling up. When filling up, after the gas nozzle shuts off with the first click, the Jeep instantly "burps" gasoline back out. I've performed 3 fill ups at different pumps, and this has occured in 2 out of those 3 fill ups.”

Should you keep driving it?
This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
