TL*THE CONTACT OWNS A 2005 GMC ENVOY. HE STATED THAT THE HEADLIGHTS, DASHBOARD LIGHTS AND REAR LIGHTS SHUT OFF WHILE DRIVING APPROXIMATELY 35 MPH OR VARIOUS SPEEDS.

I PURCHASED A 2005 GMC ENVOY IN SEPTEMBER 2005. IN THE PAST YEAR (SINCE JANUARY 2007, AT LEAST), I HAVE EXPERIENCED SEVERAL PROBLEMS WITH MY VEHICLE. THE FIRST PROBLEM IS WITH THE HEADLIGHTS. EVERYTIME I HAVE DRIVEN THE VEHICLE THE HEADLIGHTS APPEAR TO DIM/FLICKER AND THEN RETURN TO NORMAL. THIS HAS RESULTED IN ONCOMING VEHICLES TURNING THEIR BRIGHT LIGHTS ON ME THINKING MY BRIGHTS ARE ON WHEN IN REALITY MY HEADLIGHTS ARE DIMMING AND THEN RETURNING TO NORMAL. THE SECOND PROBLEM CONCERNS THE PASSENGER SIDE AIRBAG. ANYTIME A CERTAIN WEIGHT LIMIT IS MET OR EXCEEDED THE AIRBAG SENSOR IS SUPPOSED TO SWITCH TO ON, BUT THERE HAVE BEEN SEVERAL OCCASIONS WHEN SOMEONE WAS SITTING IN THE PASSENGER SEAT AND THE AIRBAG SENSOR HASN'T RECOGNIZED IT. THIRD PROBLEM, DRIVER SIDE POWER SEAT FAILURE. THERE HAVE BEEN SEVERAL INSTANCES WHEN I HAVE TRIED TO MOVE THE DRIVER SEAT FORWARD, BUT NOTHING HAPPENED....

AT VARIOUS TIME, ESPECIALLY WHEN DEPRESSING THE BRAKE PEDAL, THE HEADLIGHTS AND INTERIOR LIGHTS DIM. GM KNOWS ABOUT THE PROBLEM - TSBS 05-08-42-001 AND 06-06-03-004 BUT DOES NOT HAVE A FIX. THIS IS A SAFETY ISSUE AND NEEDS TO BE ADDRESSED. *TR UPDATED 10/23/07 *TR

DT*: THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEED THE HEADLIGHTS ILLUMINATE INTERMITTENTLY. UPON INSPECTION THE DEALERSHIP WAS UNABLE TO DUPLICATE THE CAUSE.

DT*: THE CONTACT STATED WHILE DRIVING UPHILL AT NO PARTICULAR SPEED, THE ENGINE STALLS AND OPERATES AT A REDUCED SPEED. ADDITIONALLY, THE HEADLIGHTS INTERMITTENTLY WORK AT NIGHT AND THE GAS GAUGE PROVIDES AN INCORRECT DISPLAY OF THE PROPER FUEL LEVEL. ALTHOUGH THE VEHICLE WAS SEEN BY A DEALER NUMEROUS TIMES, THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM. THE CONSUMER STATED THE ELECTRICAL SYSTEM IS FAULTY. THE LEFT FRONT WINDOW DROPPED THE LIGHTS BECAME DIM AND THE BATTERY FAILED. UPDATED 04/06/06. *JB
