Two problems related to engine stall have been reported for the 2009 Jeep Patriot. The most recently reported issues are listed below.
Filling up with gas causes engine to stall. Auto garage says it's the check ball for the fuel tank allowing for overfilling of tank and than fuel getting into the vacuum system which then cause the Jeep to stall within 5 mins. The last time it was in the middle of in intersection with the kids in the car and almost getting hit by a driver not playing attention while my husband pushed the Jeep out of the way till it wanted to start again.
The engine frequently stalls after refueling, causing a loss of power steering, acceleration or deceleration. This starts after the issue with re-fueling that led to fuel nozzle kicking off at normal re-fueling speed for 4 fill-ups, which doesn't recur any more.
