2005 GMC ENVOY Exterior Lighting Problems

DIM LIGHTS ARE FLICKERING NOT WANTING TO STAY ON

ABOUT 4 YEARS I NOTICED MY LOW BEAM HEADLIGHTS SOMETIMES WOULD NOT WORK AT NIGHT, FORCING ME TO DRIVE WITH MY HIGH BEAMS ON, BLINDING OTHER MOTORISTS. THIS WAS REPORTED TO THE DEALER'S SERVICE MANAGER AND HE SAID IT MAY COST $500 TO DETERMINE THE CAUSE. I COULD NOT AFFORD THIS EXPENDITURE. I TRY TO AVOID DRIVING AT NIGHT AND ONLY RECENTLY I HAD TO DRIVE AT NIGHT AND AGAIN MY LOW BEAMS WOULD NOT WORK, FORCING ME TO AGAIN DRIVE WITH MY HIGH BEAMS ON. MY FIANC DID A GOOGLE SEARCH AND LEARNED THIS IS A COMMON PROBLEM WITH THIS FUSE/RELAY. WE LEARNED WE COULD PULL OUT THE HIGH BEAM FUSE/RELAY WHICH IS IDENTICAL TO THE LOW BEAM AND SWITCH THEM. UPON DOING SO, THE LOW BEAMS ONCE AGAIN WORKED.

I HAD JUST DROVE MY TRUCK THE NIGHT BEFORE HEADLIGHTS WORKED FINE. I WENT TO LEAVE THE NEXT NIGHT AND NO HEADLIGHTS AT ALL. SO VEHICLE WAS STATIONARY WHEN I REALIZED I HAD NO HEADLIGHTS. I HAVE TO DRIVE WITH MY BRIGHTS ON AT NIGHT. I HAVE NO REGULAR HEADLIGHTS AT ALL. THEN MY PASSENGER SIDE WINDOW JUST QUIT WORKING AS WELL.

WHILE DRIVING, LOW BEAM HEADLAMPS WILL TURN OFF WITHOUT WARNING...HIGH BEAM HEADLAMPS STILL FUNCTION

A WHILE BACK, WE NOTICED WHILE DRIVING DOWN THE INTERSTATE AT NIGHT THAT OUR LIGHTS SEEMED TO BE FLICKERING (LOW BEAMS). IT WOULD DO IT OCCASIONALLY, BUT WE NEVER KNEW WHEN IT WOULD HAPPEN. SINCE THEN, WE HAVE HAD THE LIGHTS GO COMPLETELY OUT WHILE DRIVING, AND HAD TO TURN THE FOG LAMPS ON TO HAVE HEADLIGHTS OF ANY SORT. TONIGHT, THE LIGHTS WENT OUT, AND I PULLED INTO MY DRIVEWAY AND WAS GOING TO HAVE MY HUSBAND COME OUT AND SEE WHAT WAS GOING ON IF HE COULD. WHILE I SAT THERE WITH THE CAR RUNNING AND IN PARK, AFTER ABOUT 3 MINUTES, THEY CAME BACK ON. I HAVE READ THAT THERE WAS A RECALL ON THE LIGHT MODULAR FOR 2006+ ENVOYS, BUT MINE IS A 2005, AND HAVING THE SAME PROBLEM THAT I HEARD THE RECALL WAS FOR. I HAVE ALSO HEARD THAT THE 2005 TRAILBLAZERS WERE INCLUDED...

THE LOW BEAM HEADLIGHTS WENT OUT WHILE DRIVING 50MPH ON A HIGHWAY BECAUSE A RELAY IN THE FUSE BOX OVERHEATED AND MELTED THE FUSE BOX. I KNOW THERE IS ALREADY A RECALL ON THE TRAILBLAZER FROM THE SAME YEAR BECAUSE THEY ARE THE SAME CAR BUT THERE IS NOT ONE FOR THE ENVOY.

LOW BEAM HEADLIGHTS GO OFF WITHOUT WARNING. HIGH BEAMS STILL WORK. THIS HAS HAPPENED WHEN MOVING ON CITY ROADS AND HIGHWAYS. THE NEXT TIME I DRIVE THE CAR THE LOW BEAMS MAY OR MAY NOT WORK.

TL* THE CONTACT OWNS A 2005 GMC ENVOY. THE CONTACT STATED THAT THE EXTERIOR LOW BEAM HEADLAMP FAILED WITHOUT WARNING. THE DEALER WAS NOT CONTACTED. THE CONTACT PREVIOUSLY REPLACED THE HEADLAMP RELAY INDEPENDENTLY, BUT THE FAILURE OCCURRED APPROXIMATELY THREE TIMES. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 124,000.

THE VEHICLES HEADLIGHTS KEEP GOING OUT AT NIGHT WILL DRIVING. I HAVE BEEN DEALING WITH THIS PROBLEM FOR ABOUT 2 YEARS, I AM A CERTIFIED MECHANIC AND I BELIEVE THE PROBLEM IS THE HEADLIGHT RELAY THAT IS OVERHEATING. THIS IS THE SAME GM PART THAT IS BEING RECALLED IN OTHER GM VEHICLES. GM PART # 15016745. SO WHY HAS IT NOT BEEN RECALLED IN 05 . THE PROBLEM HAPPENS AT RANDOM THE LIGHT WILL GO OUT WHILE DRIVING OR PARKED IT DOES NOT MATTER.

I'VE HAD MY 2005 ENVOY FOR A LITTLE OVER A YEAR AND HAD MY HEADLIGHTS FLASH ON AND OFF WHILE DRIVING ON THE ROAD AND FREWAY. ON ONE OCCASION WHILE DRIVING ON A TWO LANE HIGHWAY AY NIGHT THE LIGHTS WENT OUT COMPLETELY FOR A FEW SECONDS. I WAS SO SCARED WSS REALLY GLAD FOR NO ONE BEHIND ME OR ON COMING TRAFFIC. ON ANOTHER OCCASSION I HAD TO PULL OVER ON CITY STREET AS MY LIGHTS WERE GOING ON AND OFF AND I COULD SEE THE CAR AHEAD WAS A COP AND I DIDNT WANT HIM TO THINK I WAS FLASHING FOR HELP ESPECIALLY AT 2 IN THE MORNING. IVE ALSO HAD TO EXIT THE FREEWAY BECAUSE MY LIGHTS STARTED GOING ON AND OFF AND ON AND WASNT SURE IF THEY WOULD JUST GO OUT COMPLETELY WHILE I WAS DRIVING AND SINCE IT WAS NIGHT TIME I DIDNT WANT...

TL* THE CONTACT OWNS A 2005 GMC ENVOY. WHILE DRIVING AT ANY SPEED, THE EXTERIOR LIGHTING FAILED. THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VIN WAS EXCLUDED FROM NHTSA CAMPAIGN NUMBER: 15V599000 (VISIBILITY). THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

READING NUMEROUS COMPLAINTS THAT COMPARE TO MINE THE FUEL GAUGE, OIL GAUGES, AIR CONDITIONER ARE ALL MALFUNCTIONING IN MY CAR AND I'M VERY UPSET BECAUSE ALL OF THIS SHOULD HAVE BEEN RECALLED. I PURCHASED MY CAR BRAND NEW IN 2005 AND I WILL NEVER BUY A GMC CAR AGAIN FOR THIS REASON IT'S ONE THING TO RECALL REPAIR PARTS THAT WERE BROKEN THAT TO REPAIR MALFUNCTION PARTS. VERY DISAPPOINTED. IN SHORT MY GAUGES DON'T WORK, MY AIR CONDITIONER ONLY WORKS ON ONE SIDE AND NOW MY HEADLIGHTS LOW BEAN DON'T WORK. GMC NEEDS TO RECALL AND REPAIR.

LIGHTS GO OFF AND WON'T COME BACK ON FOR 2 HOURS. YOU CAN SMELL SOMETHING BURNING BUT CANNOT FIND WHERE IT IS COMING FROM. I HAVE REPLACED ALL BULBS 3 TIMES. AND NOTHING CHANGES.

I WAS DRIVING DOWN THE HIGHWAY AFTER DARK AND MY LOW BEAMS COMPLETELY WENT OUT. I COULD ONLY GET MY HIGH BEAMS TO WORK. CURRENTLY ONLY ONE LOW BEAM IS WORKING AND THE OTHER WILL NOT WORK EVEN AFTER CHANGING THE BULB OR THE FUSE. I BELIEVE THIS IS A HUGE SAFETY CONCERN ESPECIALLY HAVING A YOUNG CHILD. IT WAS VERY SCARY GOING DOWN THE ROAD AT NIGHT AND HAVE YOUR LIGHTS COMPLETELY JUST GO OUT. I HAVE NOTICED THAT THERE ARE ISSUES WITH 06-07 ENVOYS BUT I WANTED GM TO BE MADE AWARE THAT 2005 MODELS HAVE BEEN AFFECTED AS WELL.

TL* THE CONTACT OWNS A 2005 GMC ENVOY. WHILE DRIVING, THE CONTACT NOTICED THAT THE FRONT PASSENGER SIDE HEADLIGHT FLICKERED AND FAILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO REPLACED THE HEADLIGHT AND FUSE; HOWEVER, THE FAILURE PERSISTED. THE VEHICLE WAS TAKEN BACK TO AN INDEPENDENT MECHANIC, BUT THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 133,000.

I WAS DRIVING ON A CURVY 2 LANE ROAD IN THE COUNTRY AND THE SUN WAS JUST SETTING AND I COULDN'T GET ANY LIGHTS ON MY CAR. MY LIGHTS ARE AUTOMATIC AND I JUST ASSUMED THAT I HAD BUMPED A BUTTON AND ACCIDENTALLY TURNED THEM OFF, SO I STARTED TURNING THE SWITCH TO TURN THEM ON AND IT WASN'T WORKING. I ALMOST DROVE OFF THE ROAD SEVERAL TIMES TRYING TO GET SOME LIGHT ON. I THEN HIT A SECTION WHERE TREE LINED CURVED SECTION THAT WAS PRETTY DARK. THERE HAD BEEN NO SHOULDER OR ANYWHERE TO PULL OVER THERE OR FOR SEVERAL MILES. I COULD GET BIGHTS LIGHTS, BUT NO DIM. I ENDED UP DRIVING WITH MY FOG LIGHTS, UNKNOWINGLY AT THE TIME. WE HAD JUST REPLACE THE BULBS 5 MONTHS BEFORE BUT WE TRIED NEW BULBS AND FUSES TO SEE IF THIS WOULD FIX THE PROBLEM. UNFORTUNATELY, IT DIDN'T....

AS I WAS DRIVING THE VEHICLE, THE DASHBOARD LIT UP AND THE ODOMETER AND ALL THE INFORMATION SYSTEMS WENT TO ZERO. THIS HAS HAPPENED OFTEN OVER THE YEARS. I TOOK IT TO TWO GMC CAR DEALERSHIPS AND THE FIRST ONE SAID IT WAS THE KILL SWITCH INSTALLED BY A BUY HERE PAY HERE DEALERSHIP. THE KILL SWITCH WAS REMOVED AND THE DASHBOARD CONTINUED TO FLICKER. THEN THE CAR WOULD NOT START, I TOOK IT TO ANOTHER DEALERSHIP AND WAS TOLD THEY COULDN'T FIND ANYTHING. THE CAR BEGAN TO TRIBBLE, AGAIN I TOOK IT IN AND WAS TOLD THAT I NEEDED TO CLEAN THE FUEL INJECTION SYSTEM. I DID THAT AND BOUGHT A BATTERY BUT THAT DIDN'T HELP. THE TOW DRIVER SAID IT SEEMS TO BE SOMETHING ELECTRICAL BUT THE CAR DEALERSHIP CAN'T FIND A SOLUTION. HAVE YOU HAD THIS COMPLAINT BEFORE? NOT TO CONFUSE THE COMPLAINT, I HAVE SEVERAL ISSUES....

TL* THE CONTACT OWNS A 2005 GMC ENVOY. THE CONTACT STATED THAT WHILE DRIVING AT AN UNKNOWN SPEED, THE LOW BEAM HEADLIGHTS FAILED. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC, WHO DIAGNOSED THAT THE RELAY SWITCH FOR THE LOW BEAM HEADLIGHT ASSEMBLY NEEDED TO BE REPLACED. THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN ID NUMBER: 07E014000 (EXTERIOR LIGHTING). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 103,750.

TL* THE CONTACT OWNS A 2005 GMC ENVOY. THE CONTACT STATED THAT WHILE DRIVING WITH THE HEAD LIGHTS ACTIVATED, BOTH LIGHTS WOULD INTERMITTENTLY BECOME DIMMER AND THEN INCREASE BRIGHTNESS. THE CONTACT INDICATED THAT THE DEFECT WAS REPEATED EACH TIME THE HEAD LIGHTS WERE TURNED ON. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED AND NO SOLUTION WAS OFFERED. THE FAILURE MILEAGE WAS 11,000.

THE FIRST DAY WE HAD THE TRUCK THE SPEEDOMETER DISPLAYED THE WRONG SPEED AND HAS BEEN THAT WAY. IT WORKS OCCASIONALLY. THEN A WEEK LATER THE LOW BEAM HEAD LIGHTS WENT OUT WHILE DRIVING. THEY CAME BACK ON AFTER A FEW MINS. THIS HAPPENED AGAIN A FEW DAYS AGO. THE FUEL GAGE IS IN ACCURATE AS WELL. I TOOK IT TO A SHOP AND THEY SAID THE INSTRUMENT CLUSTER NEEDS TO BE REPLACED BUT FOUND NO ISSUES WITH THE HEAD LIGHTS BUT THERE IS DEFINITELY AN ISSUE WITH THE HEADLIGHTS AND THAT IS VERY DANGEROUS. *TR

WE WERE DRIVING AT NIGHT AND THE HEAD LIGHTS WENT OUT LEAVING US IN THE DARK. WE HAVE CHECKED THE FUSES BUT THEY ARE ALL FINE. THE FUEL GAUGE DOES NOT COME OFF OF EMPTY EVEN THOUGH WE FILL IT UP. *TR

WHILE I WAS DRIVING ON THE RAMP, MY HEADLIGHTS STARTED TO FLICKER IN AND OUT. AT ONE POINT THE LIGHTS WENT COMPLETELY OUT. AFTER HITTING A BUMP IN THE ROAD THE LIGHTS CAME BACK ON. WENT TO THE MECHANIC AND THEY WERE NOT ABLE TO FIND ANYTHING WRONG. *TR

ON WAY DRIVING DOWN THE ROAD AT 8:00 PM CENTRAL TIME AT NIGHT TO MOTHERS HOUSE AT SPEED OF 45 MPH WHICH IS SPEED LIMIT 55 MPH. ALL OF A SUDDEN WHILE DRIVING, THE HEADLIGHTS START FLICKERING ON AND OFF. AS I STILL DRIVING, THE HEADLIGHTS FLICKERING ON AND OFF GOT WORSE AND WORSE. I WAS IMMEDIATELY CONCERN WITH THE SAFETY OF MYSELF AND OTHER DRIVERS ON THE ROAD THAT I HAD TO STOP AT A STORE TO CHECK THE LIGHTS. LIGHTS AND VEHICLE IS INTACT AND NOTHING SEEM TO CAUSE ANY OBSTRUCTION FOR THE LIGHTS TO FLICKER ON AND OFF. I IMMEDIATELY CAME HOME WHICH I WAS ONLY 15 MILES FROM THE HOUSE. *TR

ALMOST DUSK, HIGH BEAMS WERE ON. THOUGHT I SAW A FLICKER. GOT BEHIND ANOTHER CAR AND SAW THAT IT WAS MY LIGHTS. LOOKED TO MY PANEL AND MY VOLTAGE WAS SWINGING BETWEEN 9 VOLTS UP TO 18-19 VOLTS. TURNED ALL POWER DRAW OFF EXCEPT MY LOW BEAMS. NEEDLE KEPT SWINGING AND LIGHTS KEPT FLASHING. WAS 6 MILES FROM HOME. I MADE IT. THERE WAS A DISCHARGE TO MY SYSTEM INSTEAD OF CONTINUEING TO CHARGE. TOOK TO DEALER. NOTHING FOUND. 11-6-2012 IT HAPPENED AGAIN. HAS HAPPENED INBETWEEN ALSO. VERY INTERMITTANT. HAD BATTTERY & ALTERNATOR CHECKED AT LEAST 3 TIMES. ALWAYS GOOD. AFTER INCIDENTS, WORKS FINE UNTIL NEXT TIME. NEVER HAPPENED IN SUMMER. ALWAYS WHEN COOLER WEATHER. NOW THAT IT IS DECEMBER, AFRAID TO DRIVE AFTER DARK. THERE MUST A BULLENTIN OR RECALL??? TOO MANY COMPLAINTS ON THIS PROBLEM. DON'T WANT TO GET RID OF MY CAR. ENGINE IS GOOD. ONLY 69,000...

HEADLIGHTS BEGAN TO DIM, THEN BRIGHTEN REPEATEDLY, AS TO APPEAR TO BE "FLASHING" OTHER DRIVERS. SHORTLY AFTER, THE OIL PRESSURE GAUGE MALFUNCTIONED. AFTER THE OIL PRESSURE GAUGE, A FEW DAYS LATER THE BATTERY GAUGE MALFUNCTIONED. A FEW WEEKS LATER, THE GAS GAUGE STOPPED WORKING RIGHT. NOW, THE ENGINE CONTINUOUSLY JERKS, LIKE IT IS MISSING DUE TO LACK OF FUEL. CONTACTED GMC ON 11-09-2012. NO SOLUTION. *TR

THE REAR LIGHT, LOCATED AT THE TOP OF THE VEHICLE SNAPPED OFF WHILE TRAVELING AT A SPEED OF 55 MPH. FORTUNATELY THERE WAS AN ACCIDENT AS RESULT, BUT VERY EASILY COULD HAVE CREATED ONE. WOULD LIKE FOR GMC TO COVER THE COST TO REPAIR. *TR

THE FUEL GAGE STOPPED WORKING AND THE LOW FUEL LIGHT STAYS ON. THE CHECK ENGINE LIGHT KEEPS GOING ON AND OFF THE PORT TO CHECK ENGINE CODE DOES NOT WORK. THE INSIDE COURTESY LIGHTS STOPPED WORKING ONE BACK UP LIGHT WILL NOT WORK THE LEFT BRAKE LIGHT GETS NO POWER AND WON'T WORK. ONLY 3 OF THE 5 SPEED SETTINGS ON THE FAN WORK. GMC DEALER SAYS THEY CAN DO NOTHING, AND THAT THEY DO NOT HAVE OTHER COMPLAINTS ON THESE PROBLEMS. HOWEVER I AM ABLE TO FIND THOUSANDS OF THE SAME COMPLAINTS ONLINE IN VARIOUS CONSUMER SITES. GMC WON'T EVEN RETURN MY CALLS. *TR

OUT OF NOWHERE MY FRONT HEAD LIGHTS WENT OUT. ITS NOT THE FUSE OR THE BULBS, BOTH FRONT LOW LIGHTS WENT OUT. THE HIGH BEAMS WORK. THERE IS NO POWER GOING TO THE LIGHTS AND I HAVE TO BUY A NEW SWITCH. THE GAS GAUGE IS BROKEN. THE ABS/BRAKE LIGHT IS ON. I FEEL SO STUCK WITH THIS CAR! *TR

FUEL GAUGE JUST STOPPED WORKING. IS ALWAYS ON E. EVEN WHEN I FILL IT UP.. GAS LIGHT CONSTANTLY ON AND DINGING. I KNOW THIS IS A PROBLEM IN ENVOYS AND I FEEL GMC SHOULD BE LIABLE FOR CORRECTING THE PROBLEM. MILEAGE RANGE IS HUGE SO IT IS HARD TO TRAVEL AND KNOW WHEN TO GET GAS. ESPECIALLY ON THE INTERSTATE WHEN GAS STATIONS ARE NOT ALWAYS IN RANGE.

SPEEDOMETER JUMPS FROM 120 TO WHEREVER. CAN NEVER TELL HOW FAST OR SLOW I'M GOING. NEVER DISPLAYS CORRECT SPEED. OIL PRESSURE GAGE GOES UP AND DOWN. ALSO, HEADLIGHTS KEEP GOING OUT. HAD TO TAKE TO MECHANIC TO REDO WIRING FOR BOTH HEADLIGHTS. *TR

SPORADIC FAILURE OF SPEEDOMETER - REGISTERS CORRECTLY ONE MOMENT, OR MAY READ 30 MPH OR 0 MPG WHEN KEEPING WITH THE FLOW OF TRAFFIC ON THE INTERSTATE. WHILE THIS DOES NOT OCCUR EACH TRIP, IT DOES OCCUR SEVERAL TIMES EACH WEEK. FUEL GAUGE MALFUNCTION - READS ONE-HALF TANK AT 179 MILES; 20 MILES LATER READS ONE-QUARTER TANK. ISSUES "FUEL LEVEL LOW" WARNING AFTER REFUELING AND FOR NEXT 3 TO 4 TIMES VEHICLE IS STARTED HEADLIGHTS DIM BRIEFLY WHEN ACCELERATOR IS RELEASED. FREQUENT NEED TO REPLACE EXTERIOR LAMPS THE PROBLEMS FIRST MANIFEST IN THE NEED TO REPEATEDLY CHANGE BRAKE AND TAILLIGHT BULBS, AND THE DIMMING OF THE HEADLIGHTS, WHICH CONTINUES. THEN, SPORADICALLY, THE SPEEDOMETER STOPPED FUNCTIONING, OR ONLY REGISTERED A FRACTION OF THE SPEED THE VEHICLE WAS TRAVELING. AFTER THAT, AT START UP, THE "FUEL LEVEL LOW" WARNING, WHICH ACTIVATES WHEN THE VEHICLE DETERMINES IT HAS FUEL TO TRAVEL 40 ADDITIONAL...

OUT OF NOWHERE MY FRONT HEAD LIGHTS WENT OUT. ITS NOT THE FUSE OR THE BULBS, BOTH FRONT LOW LIGHTS WENT OUT. THE HIGH BEAMS WORK. THERE IS NO POWER GOING TO THE LIGHTS AND I HAVE TO BUY A NEW SWITCH. I ALSO HAD TO REPLACE THE ENGINE ALMOST A YEAR AGO BECAUSE THE O RINGS WENT UP. THE GAS GAUGE IS BROKEN AND MY PASSENGER WINDOW WILL NOT GO DOWN. I FEEL SO STUCK WITH THIS CAR! *TR

CAR SWITCHES INTO ALL 4W AND HIGHER BY ITSELF. I HAD BEEN TO A DEALERSHIP 3 TIMES IN ONE YEAR FOR WHICH THEY WERE UNABLE TO FIND THE PROBLEM. NOW MY WARRANTY IS UP. AFTER THAT I TOOK IT TO A TRANSMISSION SHOP WHERE THEY SUPPOSEDLY FIXED THE PROBLEM FOR OVER 800.$ A WEEK LATER IT DID IT AGAIN. NOW I HAVE THE 4WD DISCONNECTED FOR SAFETY REASONS. I WOULD BE DRIVING ON THE FREEWAY AT 60-75 MPH AND IF WOULD SWITCH AND NOT COME OUT NO MATTER WHAT I DO. I HAVE OWNED THIS VEHICLE FOR ALMOST 5 YEARS AND IT HAS DONE THIS THE WHOLE TIME. I AM A SINGLE MOM AND I DRIVE MY 17 AND 7 YEAR OLD AROUND IN THIS CAR. EVEN WITH IT DISCONNECTED IT STILL TRIES TO SWITCH. THERE IS NO SPECIFIC TIME, TEMPERATURE, OR OTHER REASON THIS HAPPENS. IT HAS HAPPENED WHEN...

TL*THE CONTACT OWNS A 2005 GMC ENVOY. WHILE DRIVING AT AN UNKNOWN SPEED, THE INTERIOR AND EXTERIOR HEAD LAMPS FAILED SIMULTANEOUSLY WITHOUT WARNING. AS A CONSEQUENCE, VISIBILITY IS SIGNIFICANTLY REDUCED, WHICH INCREASES THE RISK OF A CRASH. THE VEHICLE WAS TAKEN TO THE DEALER NUMEROUS TIMES, BUT THEY CANNOT DETERMINE THE CAUSE OF THE FAILURE. HE IS IN THE PROCESS OF NOTIFYING THE MANUFACTURER. THE FAILURE MILEAGE WAS 26,000 AND CURRENT MILEAGE WAS 46,000.

TL*THE CONTACT OWNS A 2005 GMC ENVOY. THE CONTACT STATED THAT HE WAS EXPERIENCING ISSUES WITH THE HEADLIGHTS. WHEN HIS WIFE WOULD DRIVE THE VEHICLE AT 50 MPH, THE HEADLIGHTS WOULD GET DIMMER AND DIMMER AND THEN BRIGHTEN AGAIN. ON ONE OCCASION, THE LIGHTS TURNED OFF COMPLETELY AND HIS WIFE HAD TO DRIVE HOME WITH THE HAZARD LIGHTS FLASHING. THE ISSUE OCCURRED INTERMITTENTLY. THE CONTACT TOOK THE VEHICLE TO THE DEALER AT LEAST FOUR TIMES AND THEY CHANGED THE SWITCHES AND RECALIBRATED THE LIGHTS. THE REPAIRS CAUSED OTHER FAILURES; THEREFORE, THEY RECALIBRATED TO THE ORIGINAL LIGHTS. THE DEALER STATED THAT THERE WAS NO REMEDY FOR THE FAILURE. THE MANUFACTURER STATED THAT THEY WOULD START A CASE FOR HIM AND CALL HIM BACK. THE CURRENT MILEAGE WAS APPROXIMATELY 41,000 AND FAILURE MILEAGE WAS APPROXIMATELY 23,000. UPDATED 11/14/08 *CN THE CHECK ENGINE LIGHT ILLUMINATED. THE DEALER REPLACED THE O2 SENSOR. UPDATED 11/18/08....

I OWN A 2005 ENVOY - 7 MONTHS AFTER OWNING IT - WHILE DRIVING IN THE DARK ALL THE SUDDEN THE HEADLIGHTS AND DASH/RADIO/MIRROR LIGHTS STARTED FLASHING ON AND OFF. "LIKE A COP CAR" TO THE POINT WE PRESSED ON STAR-AFRAID THE CAR WAS GOING TO STALL ON BUSY/DARK FREEWAY. WHEN I CALLED A DEALER THEY SAID OH "THAT'S NORMAL" YOU HAD TO MUCH RUNNING AND NEW CARS CAN NOT HANDLE "HEATER/RADIO ETC. "ITS NO BIG DEAL" > I CALLED ANOTHER DEALER AND THEY SAID NO-THIS IS A PROBLEM BRING THE CAR IN. ENDS UP THERE WAS A BULLETIN FOR THIS AND THE CHIP HAD TO BE UPDATED. VERY WRONG FOR THE ONE DEALER TO SAY NO BIG DEAL-WHEN THEY KNOW A UPDATE WAS OUT. *NM
