NHTSA Complaint #10142783 — 2004 GMC ENVOY

HEADLIGHTS, DRIVING LIGHTS AND ALL INTERIOR LIGHTING DIM AND FLICKER APPROX EVERY 30 SECONDS. HAS BEEN THIS WAY FOR OVER 10 DAYS, DEALER CANNOT DIAGNOSE PROBLEM UNTIL THE "SERVICE ENGINE SOON" LIGHT COMES ON, WHICH IT HASN'T. IT IS NEARLY IMPOSSIBLE TO DRIVE AT NIGHT WITH DIM, FLASHING, HEADLIGHTS, AND IS CONFUSING TO OTHER DRIVERS. ALSO, A FAN CAN BE HEARD BLOWING OFF & ON APPROX ONCE EVERY MINUTE, AND THIS IS WITH THE VEHICLE COMPLETELY TURNED OFF AND THE KEY OUT OF THE IGNITION. THIS IS CONSTANT, I'M CONCERNED THE BATTERY WILL BE DEAD AND THE CAR WON'T START, OR THAT THE LIGHTS WILL COMPLETELY GO OUT WHILE I AM DRIVING AT NIGHT. REAR PASSENGER DOOR LOCKS SUDDENLY STOPPED WORKING WITH THE REMOTE AND THE DOOR UNLOCK SWITCH ON THE DRIVER'S DOOR. I HAVE TO CLIMB OVER THE FRONT SEAT INTO THE BACK TO PHYSICALLY UNLOCK THE DOOR TO REMOVE MY CHILDREN FROM THE CAR. *NM
