AFTER I TOOK THE VEHICLE IN TO BE REPAIRED I WAS INFORMED THAT IT NO LONGER WOULD GO IN REVERSE. THE PROBLEM APPEARS TO BE THE SUNSHELL GEAR WHICH SEEMS TO BE A COMMON FAILURE WITH THIS TRANSMISSION, BECAUSE EVEN THOUGH IT WAS FINE BEFORE THE ACCIDENT THE DEALER IS CLAIMING IT WAS NOT CAUSED BY THE ACCIDENT AND THUS I AM RESPONSIBLE FOR THE ESTIMATED $2,500 TO FIX! *TR

TOLD TRANSMISSION COOLER HOSE WAS LAYING NEXT TO CATALYTIC CONVERTER - NOT SECURED. HEAT FROM CC RUBBED HOLE IN TC HOSE AND THEREFORE COULD HAVE IGNITED VEHICLE. SINCE I HAD PARKED IN THE GARAGE, IT ALSO COULD HAVE BURNED MY OTHER VEHICLE AND OUR HOUSE. MECHANIC REPLACED HOSE AND SECURED. GMC WILL NOT ACKNOWLEDGE THIS IS A PROBLEM SINCE I DID NOT TAKE IT TO A DEALER FOR REPAIR AND THEY CANNOT FIND ANY RECALL OR BULLETIN ON THIS PROBLEM. *JB

I HAVE A GMC ENVOY 4WD, ON 2 OCCASIONS THE VEHICLE HAS LOCKED THE GEAR INTO 4WD AND 4HI. VEHICLE WILL NOT RESPOND TO COMMAND TO SHIFT GEARS TO NORMAL DRIVING IN 2WD. IN TURN THIS LEADS TO PROBLEM WITH THE VEHICLE BRAKING SYSTEM--VEHICLE TAKES TOO LONG TO STOP DURING NORMAL BRAKING. THE VEHICLE ALSO BECOMES VERY UNSTABLE ON THE ROAD--KEEPS SHIFTING SIDES MAKING HARD TO KEEP THE VEHICLE IN A STRAIGHT ALIGNMENT DURING DRIVING. I HAD THE VEHICLE INSPECTED BY A GMC AUTHORIZED DEALER IN NOVEMBER, 2005 AT WHICH POINT THEY FOUND OUT THAT THERE WAS A PROBLEM WITH THE TRANSFER CASE WHICH CAUSES IT TO BREAK APART. THIS IN TURN CAUSES ALL THE OTHER SYSTEMS IN THE VEHICLE TO MALFUNCTION BECAUSE IT'S A COMPUTERIZED SYSTEM. THE TRANSFER CASE WAS REPLACED WHICH TEMPORARILY FIXED THE PROBLEM UNTIL FEB, 2006 AND THE SAME PROBLEM RECURRED. I HAVE MADE GMC AWARE OF THE PROBLEM AND THEY REFERRED ME TO THE DEALER. ON SPEAKING WITH THE DEALER I BECAME AWARE THAT THIS IS AN ONGOING PROBLEM WITH GMC ENVOY AND THE DEALER IS AWARE OF THE PROBLEM. THE ONLY WAY GMC IS RESOLVING THE PROBLEM IS REFERRING CUSTOMERS TO THE DEALER FOR A REPLACEMENT ON THE TRANSFER CASE--WHICH HAPPENS TO BE THE SAME ONE THAT KEEPS MALFUNCTIONING. AT THIS POINT GMC DOES NOT HAVE A DIFFERENT TRANSFER CASE THAT WILL RESOLVE THE ISSUE ONCE AND FOR ALL. GMC IS ALSO WILLING TO FIX YOUR VEHICLE AS LONG AS IT'S UNDER WARRANTY BUT ONCE IT'S OUT OF WARRANTY AND THE PROBLEMS WITH THE TRANSFER CASE PERSIST, YOU HAVE TO PAY OUT OF POCKET. GMC IS AWARE OF THIS PROBLEM WITH THE TRANSFER CASE BUT THEY ARE NOT LETTING THE CONSUMERS KNOW. *NM

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.

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.
