One problem related to transmission gear slipping has been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
2007 Jeep Wrangler saraha - smoke/steam coming out from under the front of the hood (twice). I have taken it to the dealership and they "could not find any leaks" yesterday, my transmission was slipping, stalling me in the path of online traffic. This vehicle is only 2 years old and I am a single mother that is afraid for the safety of myself and my children who are passengers in this vehicle. Each time I voice my concerns to my Jeep dealership they "can't find anything wrong. " I know that vehicle as well as you would your own body, and there is definitely something wrong.
