Please also check out the statistics and reliability analysis of the 2008 Jeep Grand Cherokee based on all problems reported for the 2008 Grand Cherokee.
9/1/15 at approximately 8:20 p. M. Unintended change in ignition switch to the off position resulting in engine shutdown, electrical and power steering completely shutdown/lock. Collision averted by pulling resting 45 degree angle against the curb. Engine restarted thereafter. T/c to another dealership (this time downtown los angeles) and I am glad to report an appointment for this coming Friday, 9/4/15.
Engine stops running while the vehicle is being driven. Typically the failure occurs when the throttle is closed during deceleration I. E. (when decelerating to exit the freeway or decelerating to stop in traffic). The problem was first encountered at 14k miles and persists to date. The vehicle currently has accrued 46k miles. The vehicle has been to the dealer on 5 occasions for diagnosis/repair of the problem. The dealer cannot duplicate the problem and no fault codes are stored in the on board diagnostic system memory. Chrysler customer service was contacted for assistance to no avail. The Chrysler customer service representative merely contacted the servicing dealer and was told no driveability issues exist with the vehicle. I note the vehicle stopped running in traffic after leaving the dealer service department 4/22/2011 (Chrysler customer service was advised). This condition is unsafe as steering and braking systems are significantly degraded without power assist.
