One problem related to transmission failure has been reported for the 2008 Jeep Patriot. The most recently reported issues are listed below.
My 2008 Jeep Patriot has only 59k miles on it. My wife was driving on the interstate and it began to make a roaring sound from the transmission. We took it to the dealership and they said the cvt transmission needed replaced. Jeep will not provide any assistance and want over $4000 for a transmission replacement of a transmission that is not able to be service and (according to owners book) needs fluid changed around 120k. I researched and found multiple people that have cvt transmission failures at low mileage. Jeep is even getting rid of the cvt in the new Jeep Patriot. This transmission is a lemon and the company should assist with replacement when it goes out early.
