One problem related to owners/service manual has been reported for the 2006 Jeep Commander. The most recently reported issues are listed below.
While driving, Jeep Commander will randomly jump to neutral and when press gas will rev up only. Have to either manually shift the gear to neutral then back to drive or pullover turn off Jeep and star back up. The physical shifter does not move to neutral position just the actual gear. Does at random times and speeds and when it does the Jeep will not accelerate which can cause accidents especially on highways.
