One problem related to gasoline engine has been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
1: driving at highway speed with 3400 miles on the car. 2: all dashboard lights came on and engine stopped. Within a few seconds, the vehicle resumed operation. 3: nothing has been done. I have been researching and waiting for this issue to occur, as it has for many other 2007 Jeep Wrangler owners. It will be going in to the dealer, but as of late, there is no "fix" for this issue.
