2004 GMC ENVOY XL SPEEDOMETER AND TACHOMETER INACCURATE READINGS. SPEEDOMETER READINGS SOME AS HIGH AS 115-120. HAVE NO IDEA THE ACTUAL SPEED AT WHICH I AM TRAVELING. TERRIFIED TO THINK OF USING CRUISE CONTROL WHEN TRAVELING INTERSTATES MANY TIMES EACH YEAR. HAVE REVIEWED ONLINE COMMENTS AND I AM NOT THE ONLY PERSON EXPERIENCING THIS PROBLEM. GM/GMC APPEARS TO KNOW ABOUT THE PROBLEM BASED ON THE COMMENTS AND DEALER/SERVICE RESPONSES. STANDS TO REASON THAT A FAULTY INSTRUMENT PANEL COULD AFFECT OTHER FUNCTIONS OF CAR. NOT KNOWING SPEED AT WHICH I AM TRAVELING IS DIRE SAFETY ISSUE. WHAT HAS NHTSA DONE TO ADDRESS THIS ISSUE WITH GM/GMC? *TR

WE HAVE HAD NUMEROUS ELECTRICAL PROBLEMS WITH THE ENVOY, BUT I AM WRITING ABOUT THE INSTRUMENT CLUSTER PANEL. THE FAILURE OF THE PANEL CAUSED THE SPEEDOMETER TO FAIL. THE SPEEDOMETER REGISTERS OVER 120 MPH REGARDLESS OF THE SPEED OF THE VEHICLE, OR WHETHER THE VEHICLE IS TURNED OFF OR ON. THE MECHANIC WHO INVESTIGATED THE ISSUE STATED THAT THERE WERE NUMEROUS DIAGNOSTIC ERRORS THAT HAD TO BE CORRECTED BEFORE HE COULD SUCCESSFULLY DIAGNOSE THE BAD INSTRUMENT CLUSTER. THIS IS A KNOWN ISSUE WITH THE ENVOY, GMC WILL NOT ACCEPT RESPONSIBILITY AND THE FAILED INSTRUMENT PANEL CAN RESULT IN ACCIDENTS.

IN DECEMBER 2009 MY 2004 ENVOY XL'S TACHOMETER WENT OFF LINE. IT STARTS AT ABOUT THE 3 O'CLOCK POSITION. THEN A MONTH LATER THE ODOMETER STUCK AT ABOUT 40 MILES PER HOUR EVEN THOUGH I WAS STOPPED OR OBVIOUSLY DOING OVER 40. WHEN THE VEHICLE IS TURNED OFF AND RESTARTED IT CORRECTED ITSELF BUT WAS ERRATIC AND WOULD TICK ITS WAY UP TO ABOUT 40-50MPH THEN WOULD STOP GOING UP. THIS HAS BEEN AN ONGOING PROBLEM WITH MANY 2004 ENVOYS. THE DEALER SAID IT WAS A INSTRUMENT PANEL PROBLEM AND THAT THEY WOULD HAVE TO REPLACE IT AT A COST OF AROUND $500.00 THIS IS A SERIOUS SAFETY PROBLEM. WHEN REDUCING SPEED TO ACCOMMODATE A CURVE THAT RECOMMENDS A REDUCED SPEED I CAN NOT TELL WHAT MY ACTUAL SPEED IS TO SAFELY MAKE THE CURVE. SPEED LIMITS ARE POSTED FOR SAFETY REASONS AND IF WE CANT TELL HOW FAST WE ARE GOING DO TO A FAULTY INSTRUMENT PANELS IT PUTS PEOPLE IN DANGER. DEALERS AND GMC SEEM TO KNOW ABOUT IT AND HAVE NOT YET RECALLED THE VEHICLES TO CORRECT THE SAFETY PROBLEM NOT TO MENTION THAT $500.00 IS A LOT OF MONEY FOR MOST PEOPLE TO HAVE TO PAY FOR A SAFETY PROBLEM THAT THE MANUFACTURE SHOULD BE FIXING. *TR

DURING THE ERRATIC PHASE, I TOOK THE VEHICLE TO THE DEALER AND THEY SAID THEY DID NOT NOTICE A PROBLEM. I HAVE NOT TAKEN ANY STEPS TO FIX IT NOW THAT IT IS STUCK AT 120 MPH BECAUSE THE VEHICLE IS OUT OF WARRANTY AND THE DEALERSHIP WILL NOT COVER THE COST. *TR

WHILE DRIVING INTERSTATE 80 IN NEBRASKA DURING THE MONTH OF DECEMBER 2009, THE SPEEDOMETER ON MY 2004 GMC ENVOY GOT STUCK ON 70 MPH. I HAD NO IDEA HOW FAST I WAS GOING AND IT WAS VERY DANGEROUS DRIVING WHILE NOT KNOWING HOW FAST I WAS GOING IN CONSTRUCTION ZONES AND THE ROADS WERE VERY SNOW AND ICE PACKED. SINCE DECEMBER, I HAVE PURCHASED A GPS WITH A SPEEDOMETER. I DO NOT WANT TO PAY TO GET THIS FIXED BECAUSE I FEEL THIS IS A SAFETY ISSUE AND GM SHOULD ISSUE A RECALL. THERE ARE TIMES THE SPEEDOMETER WILL WORK, THEN FOR NO APPARENT REASON WHILE DRIVING DOWN THE HIGHWAY IT WILL GET STUCK. *TR

4RQ17002 · 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.

DURING THE COURSE OF THIS EA INVESTIGATION, ODI OBSERVED THAT THE MAJORITY OF THE COMPLAINTS (88%) AND WARRANTY CLAIMS (94%) WERE REPORTED FOR VEHICLES THAT ARE REGISTERED FOR USE IN THE SALT BELT REGION OF THE US.THIS AREA INCLUDES 20 STATES IN THE NORTHEAST, MID ATLANTIC AND THE MIDWEST REGIONS AND THE DISTRICT OF COLUMBIA.CONSUMERS IN THE SALT BELT REGION REPORTED TO ODI THAT THEY COULD SMELL FUEL VAPORS IN THEIR VEHICLES WHILE DRIVING.UPON FURTHER EXAMINATION OF THEIR VEHICLES, THEY DISCOVERED THAT FUEL VAPORS WERE COMING OUT OF THE TOP OF THE FUEL TANK. THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.
