I PURCHASED MY 2003 GMC ENVOY XL IN 2008 FROM A NY DEALER WITH 60,000 MILES ON IT, THE CAR DIDN'T REGISTER ANY ACCIDENTS WITH CARFAX. THE DAY AFTER I PURCHASED THE CAR MY BATTERY WENT DEAD AND I WAS STRANDED AT 7AM WITH MY KIDS. THE DEALER PAID FOR THE TOW AND REPLACED THE BATTERY. A YEAR LATER WHILE DRIVING TO MY SONS BASKETBALL GAME AT NIGHT, THE HEADLIGHTS COMPLETELY SHUT OFF. I PULLED OVER AND USED MY HAZARDS, MY SON INSPECTED THE LIGHTS AND COULD SMELL SOMETHING WAS BURNING..THE DRIVER SIDE HEADLIGHT WIRE WAS BURNT BADLY. WE REPLACED THE LIGHT AND THE WIRING. THE NEXT DAY NOT ONLY DID THE LIGHTS SHUT OFF AGAIN WHILE DRIVING AT NIGHT, BUT I COULDN'T PUT MY WINDOW UP! THE DRIVER SIDE WINDOW PANEL DID NOT WORK, BUT THE OTHER WINDOWS WORKED FINE. I PAID $400 TO HAVE THE PANEL REPLACED. (NOW THE SEAT ADJUSTMENT PANEL IS NOT WORKING ON THE DRIVER SIDE) THE BATTERY HAS BEEN REPLACED 3 TIMES IN 3 YEARS! WHEN EVER I WOULD USE THE WINDOW, OR THE HEAT VENT, OR THE CHARGER INLETS IN MY CAR THE HEADLIGHTS WOULD FLICKER DIM. MY MECHANIC DID A AMPS CHECK WHILE MY PHONE WAS PLUGGED IN,CAR WAS RUNNING,RADIO ON, AND HEATER ON AND STATED THE AMPS WERE FINE, UNTIL I HIT THE WINDOW BUTTON, THEN THE AMPS WENT WAY DOWN. COST TO REPLACE ALTERNATOR $350.00, THAT WAS IN 2010, SO FAR IN 2011 I HAVE AWOKEN 3 MORNINGS IN A ROW TO A DEAD CAR. I SAT IN THE CAR WITH CAR OFF, DOORS LOCKED ONE NIGHT TO SEE WHAT GOES ON OVER NIGHT..WELL THE ALARM SENSOR BUTTON DIDN'T STOP BLINKING RED, THE SEAT ADJUSTMENTS KEPT MOVING EVERY 4 MINS, THE REARVIEW MIRRORS WERE MOVING NON STOP, AND THE HORRIBLE BEEPING SOUND INSIDE THE CAR WAS NON STOP! THE RADIO DASH DIDN'T SHUT OFF EITHER, IT WAS PIPING HOT AFTER A HALF HOUR OF SITTING. *TR

IT REFLECTS ERRATIC RPM'S WHEN IT FIRST STARTED THE NEEDLE WOULD RAISE TO BETWEEN 5-6K RPMS WHEN AT IDLE, AFTER APPROX 2 WEEKS IT WOULD RESET ITSELF TO NORMAL, APPROX 2-3 WEEKS LATER IT WOULD REGISTER APPROX 6-7K RPMS THEN RESET ITSELF ONCE AGAIN TO NORMAL. NOW IT IS PEGGED ALL THE WAY AROUND AND POINTING DUE SOUTH, IT ATTEMPTS TO RESET ITSELF BUT WILL NOT. I AM ALSO SEEING ERRATIC INDICATIONS ON THE FUEL GAUGE. ON THE EDMUNDS ENVOY FORUM THERE ARE QUITE A FEW ENVOY OWNERS THAT ARE HAVING THE SAME PROBLEMS, SOME ARE HAVING SPEEDOMETER LEVEL PROBLEMS. WAS IN CONNECT WITH GMC REPRESENTATIVE AND SHE COULD/WOULD NOT HELP SINCE MY VEHICLE WAS OUT OF WARRANTY. I EVEN SUGGESTED THAT THEY PAY AT LEAST 1/2 THE COST OF REPAIRS. I BELIEVE THIS A COMPONENT FAILURE AND COULD POSSIBLY BECOME A SAFETY ISSUE ESPECIALLY WITH THE SPEEDOMETER AND GAS GAUGE PROBLEMS. THE PROBABILITY OF ALSO HAVING SPEEDOMETER FAILURE IN THE NEAR FUTURE IS PRETTY GOOD BET.

WE HAVE 112,000 MILES ON THE VEHICLE HOWEVER RESEARCHING ON LINE FOR SPEEDOMETER ISSUES, THERE APPEARS TO BE AN ISSUE. I CANNOT TELL WHAT SPEED WE ARE GOING AND THEN ONCE IT WARMS UP IT BEGINS TO WORK RECORDING HALF SPEED. IT MAY OR MAY NOT EVENTUALLY RECORD ACCURATE SPEED. THIS IS A SAFETY ISSUE FROM THE STAND POINT THAT I USE MY SPEEDOMETER TO DETERMINE SPEED GOING INTO CORNERS AND OFF RAMPS. WITHOUT THIS ABILITY, MY SPEED IS ESTIMATED WHICH DOES NOT ALLOW ACCURATE SPEED INTO CURVES. THIS APPEARS TO BE ELECTRICAL IN NATURE AS IT IS INTERMITTENT. SEEMS LIKE THERE SHOULD BE A RECALL TO CORRECT THIS PROBLEM. *TR

Official recalls
3Oct 27, 2005
CERTAIN SPORT UTILITY VEHICLES HAVE A REAR SIDE CLOSURE LATCH THAT MAY NOT LATCH OR UNLATCH DUE TO CORROSION CAUSED BY ROAD SPLASH, SUCH AS WATER AND ROAD SALT. THESE VEHICLES WERE ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE FOLLOWING STATES: CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA.
Consequence & remedy
Consequence: IF THE DOOR IS NOT LATCHED PROPERLY AND IT GOES UNNOTICED, IT MAY OPEN WHILE THE VEHICLE IS IN MOTION. IF AN UNBELTED OCCUPANT FELL OUT OF THE VEHICLE, PERSONAL INJURIES COULD OCCUR.
Remedy: DEALERS WILL INSTALL A SEAL ALONG THE LOWER PART OF THE ROCKER PANEL TO PREVENT INTRUSION OF CORROSIVE MATERIAL, AND INSPECT THE REAR SIDE CLOSURE LATCHES. FUNCTIONAL LATCHES WILL BE CLEANED AND LUBRICATED. NON-FUNCTIONING LATCHES WILL BE REPLACED. THE RECALL BEGAN ON FEBRUARY 24, 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR ISUZU AT 1-800-255-6727.
Nov 1, 2004
ON CERTAIN SPORT UTILITY VEHICLES, VIBRATION AND HEAT MAY CAUSE THE TAIL LAMP/STOP LAMP BULB TO LOOSEN IN ITS SOCKET. IF THIS OCCURS, THE BULB MAY FLICKER AND EVENTUALLY BECOME INOPERATIVE.
Consequence & remedy
Consequence: AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE TAIL LAMP/STOP LAMP ASSEMBLIES, AND IF NECESSARY, REPLACE THEM. THE RECALL BEGAN ON NOVEMBER 22, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, OLDSMOBILE AT 1-800-630-6537, BUICK AT 1-866-608-8080, OR GMC AT 1-866-996-9463.

CERTAIN SPORT UTILITY VEHICLES HAVE WINDSHIELD WIPER SYSTEMS THAT WILL NOT TURN ON, CEASE OPERATION WHILE IN USE, FAIL TO TURN OFF/ON BY THEMSELVES (MOISTURE SENSITIVE WIPER SYSTEM), OR HAVE CONTINUOUS WINDSHIELD WASHER PUMP OPERATION BECAUSE THE PRESENCE OF WATER WITHIN THE WIPER MODULES CAN EITHER CAUSE A SHORT CIRCUIT OR CAN LEAD TO THE CORROSION OF COMPONENTS WITHIN THE MODULE.
Consequence & remedy
Consequence: DEPENDING ON THE OCCURRENCE AND WEATHER SITUATION, DRIVER VISIBILITY COULD BE REDUCED, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL COVER THE WINDSHIELD WIPER MODULE VENT HOLE WITH A PATCH. ALSO, THE WIPER MOTOR, CIRCUIT BOARD, AND ELECTRICAL CONNECTOR WILL BE INSPECTED TO SIGNS OF WATER INTRUSION AND/OR CORROSION AND BE REPLACED AS REQUIRED. THE RECALL BEGAN JULY 6, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438; OLDSMOBILE AT 1-800-630-6537; OR GMC AT 1-866-996-9463.

6RQ17002 · Loss Of Headlights
Opened Apr 24, 2017 · Closed Mar 29, 2021
Status: closed (inferred from source dates) · Exterior Lighting:headlights
The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.
