After looking into this issue, I have found that this is not a common occurrence and there is even a recall for this exact reason for the 2016 Jeep Patriots. The vehicle was taken to the local Jeep dealership, and they stated there was no way of knowing what the issue is without the check engine light coming on. …

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 [redacted] son was in the car with me. …
