2009 Jeep Patriot engine problems

“Engine stalls only after filling up gas, resulting in check engine light or oil light turning on. I have taken it to numerous mechanics, who have all given me different answers, with anywhere from issues with EVAP hoses and fuel tank, to the fuel pump, or purge system. Problem was never addressed or mentioned when bought from dealership in June 2025 but noticed immediately after filling up gas for the first time since purchase of the car and problem occurs continuously after filling up gas. Not sure if related either, but if gas tank is overfilled at all in the slightest, it leaks out the bottom immediately.”

“We bought this car in March of 22 for our daughter. She used to drive back and forth between Mankato, MN and Coralville, IA. Every time she has driven it, the overheating light has come on and the car slows down below 50 mph. We have taken it to the mechanic, who we bought it from, three times for repairs. Every time we think it is done, the same thing happens. She has also had two different mechanics look at in Mankato. On Friday, September 2, 2022, after only driving an hour, the overheat light came on the car slowed to below 50 mph. She said there was a semi behind her that almost rear-ended her when this happened. I believe there is a danger with this car. I have read a lot complaints, on different online forums, that this year and model of Jeep has a problem with its CVT-continuously variable transmission. https://repairpal.com/cvt-transmission-543 "Problem Description There have been numerous complaints of early transmission failure, even with with normal servicing. Issues start with a whining noise, overheat warnings, and an inability to accelerate. The most common solution is replacement of the transmission. Late 2014 model year Patriots changed to a…”

“Car shuts off after fueling. Is a common problem with other Jeep owners found on Google. My mechanic actually found the articles. Apparently it is a Rollover valve issue. Like others have suggested, not to fill the fuel tank full unless you want to pay over $1000 for a new gas tank. I don't want to drive in fear this car is going to keep shutting off. Why hasn't this been fixed when so many others have had the same issue?”

“JEEP STUTTERS AND STALLS OUT IMMEDIATELY UPON FILLING TANK WITH GAS, ALMOST GOT HIT MANY TIMES PULLING OUT OF GAS STATION, THIS NEEDS TO BE ADDRESSED, IT IS DEADLY AND MANY OTHER PEOPLE ON VARIOUS FORUMS HAVE REPORTED SAME PROBLEM. NHTSA NEEDS TO STOP OVERLOOKING THIS ISSUE. IT IS A COMMON VEHICLE STILL ON THE ROAD TODAY AND I HAVE NO PLANS TO GET RID OF THE CAR FOR AT LEAST ANOTHER 5 YEARS MINIMUM. RECALL THIS ISSUE, IT IS DEADLY AND DANGEROUS AND I WILL NOT BE A STATISTIC.”
