While driving the vehicle will randomly, without warning or any dash notification icons alerted, turn off engine- radio, lights, a/c everything else is still on but engine is off. This occurred 4 times in less than a 2 mile distance without any check engine or notification lights on the dash before, during, or after the event. This issue originally started about a week ago, when the check engine and throttle system notification icons came on, followed immediately by the car going into what seemed to be limp mode. Car was towed to the jeep dealership, they said issue was the battery and that an oil change was needed. Had issues addressed took the car how two days later, same issue occurred again. While driving same two icons suddenly came on then car went immediately into limp mode and was not driveable. Took the car back to the jeep dealer, they took a few days to drive it and stated it was the fuel throttle body that needed to be replaced. Had the part replaced and the car drove as normal, no icons on dash after the repair, next morning same issue occurred again while driving, icons come on dash, immediately car goes into limp mode. Circling back to the biggest concern, is I’ve found large amounts of owners having the exact same if not oddly similar issues with varying years of the jeep patriots. Many are reporting my reason for this report in that suddenly after Jeep dealers require all these repairs they’re experiencing the engine completely shutting off WHILE DRIVING. This is incredibly dangerous and I’m concerned as to why there A. Isn’t a repair for this common issue in these models, and B. Why a recall hasn’t been submitted for the most dangerous scenario where many owners are having their cars engines shut down while driving, and some at high speeds. This is incredibly dangerous and frustrating that our safety has not been addressed when online there are years worth of forums for these issues without resolution.

Catalytic converter is bad. Check engine light is on. Other 2015 Patriots have a recall for catalytic converter recall but mine is not on that list. Should be.

Over the past year, the car has had 4 crank position sensors, new pig tails/connectors on the wire harness, a new throttle body, and a new MCM. The Jeep will randomly shut off without warning either at stoplights/traffic or on the highway at speed. While at speed, the car will "restart" itself, but if it stalls while stagnant a manual restart is necessary. When the stalling occurs, warning lights do not appear on the dash. Lately, however; the crank position code P0339 has come up with the check engine light. I recently experienced a crank position sensor code followed by a cylinder 3 misfire which caused the car to go into limp mode. Once I replaced the MCM, the misfire went away. Most recently (today) the car stalled in the middle of an intersection while making a left turn; my [XXX] son was in the car with me. Since it was a stop light, the car was able to be restarted in time, but had it been a stop sign/non-stop oncoming traffic, the situation could have been much worse.

My transmission failed while going 65 on the interstate with no warning. The only warning lights that were on, was the check engine light and the overheat light, which only came on about 30 seconds before transmission failure. The vehicle lost all power, which made it reduce speed, extremely fast, and wouldn’t gain speed at all which almost caused the vehicle behind me to hit me at a high rate of speed. I had a hypersensitive special needs child in my car at the time, and the very loud, high pitch whiny noises has actually had him struggling since it happened. I am in extremely bad health as well, with a heat intolerance and this jeep stranded myself, and my special needs child on the side of the interstate for approximately two hours because I was out of town and had to wait for someone to travel to me. Temp that day was approximately 90 degrees. Vehicle is available for inspection upon request. The vehicle was checked out by two service centers, one being a certified Jeep dealership, and both confirmed that my transmission failed due to overheating transmission because of hot weather, and that was an ongoing issue with other patriots as well. Spent about three hours, trying to get a hold of Jeep, the representatives are rude and disrespectful, and they wanted me to pay more money for a specific diagnostic test that they required because it would better help them, but not benefit me at all.

My truck goes into a code where the electric throttle control light, the engine light, and the tire traction light comes on. When the vehicle does this it reduces the speed to 35 no matter what or where you are. When you ho get the engine light checked, the code says it's a suction problem 🙄. Jeep started doing this in the colder weather than progressed to every other week
