Dodge Journey sudden poor gas mileage issue possibly linked to transmission overheating on Dodge Journey

Some Dodge Journey owners report experiencing a sudden drop in gas mileage due to various factors that affect fuel efficiency. Common issues include engine misfires caused by bad coil packs, spark plugs, or fuel injectors, which can hinder fuel combustion efficiency. Additionally, starting problems related to a dead battery, faulty starter, or fuel delivery issues may contribute to decreased mileage. A dirty fuel filter is another potential culprit that can impact fuel flow and efficiency. Furthermore, malfunctioning components such as clogged fuel injectors, old engine air filters, and damaged piston rings can also lead to poor gas mileage. While transmission overheating is a concern, owners are advised to investigate these other common issues first and consult a mechanic if they suspect transmission problems to ensure optimal performance and fuel efficiency.
