2009 CHEVROLET AVALANCHE Steering Problems

ON 10/13/2015 I TOOK MY AVALANCHE TO GALLES CHEVROLET , ALBUQUERQUE, NM FOR REPAIR OF A CRACKED INSTRUMENT CLUSTER AND FAULTY L/R DOOR LOCK ACTUATOR. I PICKED IT UP ON 10/15/2015. WHILE PARKING THE TRUCK ON 10/17/2015 I SHUT OFF THE ENGINE AND SUDDENLY THERE WAS NO POWER TO LOCK THE LOCKS WITH THE KEY FOB. IT WAS AS IF THE BATTERY I HAD HAD REPLACED NEW ABOUT 6 WEEKS PRIOR SUDDENLY WENT DEAD. THEN I HEARD A CLICKING NOISE IN THE DOORS/LOCK ACTUATORS AND SUDDENLY THE BATTERY POWER WAS RESTORED. I NEXT EXPERIENCED THIS PROBLEM WHILE DRIVING ON NEW MEXICO HWY 485 ON 10/25/2015 ONLY WORSE. WHILE DRIVING FOR ABOUT 10 MILES AT SPEEDS OF BETWEEN 35-50 MPH THE DOOR LOCK ACTUATORS LOCKED AND UNLOCKED THE DOORS NUMEROUS TIMES, THE AIRBAG, STABILATRAC, AND ABS SENSOR ALARMS KEPT ACTIVATING AND THE CRUISE CONTROL SUDDENLY DISENGAGED MANY TIMES AGAIN WHILE DRIVING....
