NHTSA Complaint #10644613 — 2005 DODGE DURANGO

PROBLEM STARTED WITH "SRV 4 WD" LIGHT ON DASH GOING ON AND GOING OFF AT RANDOM WHILE DRIVING. SOON AFTER THIS INITIAL PROBLEM, WITH VEHICLE PARKED AND IGNITION OFF,4 WHEEL DRIVE ATTEMPTS TO ENGAGE AND DISENGAGE. THE ENGAGE/DISENGAGE PROCESS MAY OCCUR 2 TO 6 TIMES. THE SOUND OF THIS ENGAGEMENT/DISENGAGEMENT IS CLEARLY AUDIBLE. ON ONE OCCASION THE VEHICLE ACTUALLY ENGAGED FOUR WHEEL DRIVE BUT THERE WAS NO LIGHT ON THE DASH INDICATING THE VEHICLE WAS IN 4 WHEEL DRIVE. AFTER DRIVING THE VEHICLE APPROXIMATELY .5 MILES, 4 WHEEL DRIVE DISENGAGED WITH A VERY LOUD SHIFT NOISE. AT THIS SAME TIME, THE "4 LO" DISPLAY LIGHT ON THE DASH BEGAN TO FLICKER. IT NOW BLINKS AS IF THE VEHICLE IS ATTEMPTING TO ENGAGE "4 LO" WHILE THE VEHICLE IS IN MOTION AND THE SELECTOR SET TO ALL WHEEL DRIVE. I AM STILL ABLE TO ENGAGE AND DISENGAGE FOUR WHEEL DRIVE USING THE SELECTOR SWITCH ON THE DASH MANUALLY AS IS THE CASE WITH NORMAL 4 WHEEL DRIVE OPERATION FOR THIS VEHICLE. AT THIS POINT THE VEHICLE HAS NOT SWITCHED FROM AWD TO 4 WD WHILE IN MOTION AT HIGHWAY SPEED. I AM AWARE HOWEVER THIS IS A SITUATION WHICH CAN OCCUR DURING VEHICLE OPERATION WHILE EXPERIENCING THESE 4 WHEEL DRIVE MALFUNCTIONS. *TR
