One problem related to automatic transmission cooler has been reported for the 2009 Jeep Patriot. The most recently reported issues are listed below.
The transmission over heats and the speed slows down automatic and will cause the car to stall. This happens on all long road trips. The chain drive transmission is at fault. Jeep covered this up by putting censor on cooling part to mass the real fault. This has happen three times always on long mileage trips. Thank you.
