One problem related to air brake wheel speed sensor has been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
Approx. 3 weeks after we purchased our new 2007 Jeep Wrangler we experienced a premature engagement of the esp system under normal driving conditions at a speed of 35mph. This caused the vehicle to swerve due to automatic braking and shut down of throttle. We took the vehicle to Chrysler service and they replaced 3 leaking brake calipers. Approx. 2 weeks later we experienced the same problem while exiting the interstate at a low speed. We immediately returned the vehicle to Chrysler service and they replaced the rear wheel speed sensors. Again, 1 week later the same problem occured while exiting the interstate. Chrysler service replaced the steering wheel angle sensor. The 4th incident occurred 2 weeks later while pulling out of a parking lot. The service department cannot duplicate or repair the problem. We filed a lemon law claim with Chrysler that is currently under settlement. We have been told they will be replacing the vehicle and the paperwork is being processed.
