I WAS DRIVING ON THE HIGHWAY WITH THE CRUISE CONTROL ON. WHEN I TAPPED THE BRAKES TO TURN OFF CRUISE CONTROL, MY SPEEDOMETER WAS STUCK AT MY CRUISE CONTROL SPEED OF 65. MY VEHICLE CAME TO A COMPLETE STOP AND MY SPEEDOMETER BACKED OFF TO 45 MPH, BUT WOULD NOT RETURN TO ZERO. AFTER STOPPING, THEN TURNING ONTO ANOTHER HIGHWAY, MY SPEEDOMETER WAS STILL STUCK AT 45 MPH. MY CRUISE CONTROL WAS PREVIOUSLY SET AT THE SPEED LIMIT FOR THE HIGHWAY AT 65 MPH AND I HIT THE BUTTON TO RESUME CRUISE CONTROL. WHEN I REACHED MY DESTINATION, I TURNED MY VEHICLE OFF, THINKING IT WOULD RESET TO ZERO WITHOUT POWER; YET, IT IS STILL STUCK AT 45 MPH AND MY CAR IS OFF AND PARKED IN MY DRIVEWAY. *TR

I WAS DRIVING IN TOWN AND MY SPEEDOMETER STOPPED WORKING AT 0. THE OIL GAUGE IS NOT WORKING, PEGGED OUT AT THE MAX AND MY ENGINE LIGHT IS NOW CONSTANTLY ON. THESE EVENTS, PARTICULARLY THE SPEEDOMETER NOT WORKING, IS A MAJOR SAFETY HAZARD. NOT DRIVING AT CONTROLLABLE SPEEDS CAN LEAD TO AN ACCIDENT AND DEATH. THE PARTS AND LABOR TO FIX THIS PROBLEM IS $550. WHILE RESEARCHING THIS PROBLEM ON THE INTERNET, I'VE FOUND OUT THAT THIS IS A COMMON PROBLEM WITH GMC'S IN THIS YEAR. THERE SHOULD BE A RECALL WITH THE CLUSTER UNIT ON 2004 GMC ENVOYS. GMC SHOULD TRY TO PREVENT DEATHS THAT THEIR PRODUCTS MAY CREATE. *TR

I PURCHASED A 2004 GMC ENVOY WITH APPROXIMATELY 50000 MILES ON IT IN MAY OF 2006. ABOUT 4 MONTHS LATER, THE SPEEDOMETER STARTED ACTING SLIGHTLY ERRATIC, REPORTING SPEEDS VARYING BY 10-20 MPH (I.E. ON THE HIGHWAY, KEEPING UP WITH TRAFFIC AT 65 MPH, THE SPEEDOMETER WOULD REPORT 45 MPH OR SOMETIMES 80 MPH. OVER THE PAST FEW WEEKS, THE PROBLEM HAS GOTTEN MUCH WORSE, WITH THE SPEEDOMETER REPORTING 120 MPH AT HIGHWAYS SPEEDS, AND 50 MPH AT A STOP, SOMETIMES NOT REGISTERING ANY SPEED AT ALL (O MPH). THE CRUISE CONTROL HAS ALSO STOPPED WORKING, WHICH I AM ASSUMING IS RELATED TO THE SPEEDOMETER MALFUNCTION. I SEARCHED ONLINE, AND APPARENTLY THERE ARE MANY OTHER GMC OWNERS WITH THE SAME EXACT PROBLEM. PLEASE SEE LINK BELOW: HTTP://WWW.TOPIX.NET/FORUM/AUTOS/CHEVROLET-TAHOE/T2BGKBGI55EKNU77C/P1 THIS IS THE FIRST GMC CAR I HAVE PURCHASED AND I AM DISSATISFIED WITH THIS SAFETY ISSUE. I AM A PRETTY GOOD GUESS AT HOW FAST I AM GOING, HOWEVER WITHOUT AN ACCURATE SPEEDOMETER I FEEL I AM TAKING UNNECESSARY CHANCES. AS A REALTOR, I OFTEN HAVE CLIENTS IN MY VEHICLE AND I AM CONCERNED FOR THEIR SAFETY AS WELL. I FILED A COMPLAINT WITH GMC, BUT I WAS REFERRED TO THE DEALER AS THERE ARE NO CURRENT RECALLS FOR THIS PROBLEM. THE DEALER SAYS THAT THIS IS A $500 FIX, AND I AM CONCERNED AS THIS APPEARS TO BE A MANUFACTURER DEFECT, BASED ON THE NUMBER OF OTHER CONSUMERS WITH THIS SAME ISSUE. I NEVER EXPECTED TO HAVE AN ISSUE THIS PROBLEMATIC WITH A VEHICLE 2 YEARS OLD. I HOPE THAT BY REPORTING THIS ISSUE, THE NHTSA WILL BE ABLE TO HELP ME AND THE OTHER HUNDREDS OR THOUSANDS OF CONSUMERS WITH THIS SAFETY ISSUE. THANK YOU FOR YOUR TIME.

ON CERTAIN TRUCKS AND SPORT UTILITY VEHICLES, THE DRIVER WISHING TO SIGNAL A TURN BY MOVING THE DIRECTIONAL SIGNAL LEVER, (UP OR DOWN) MAY CAUSE THE FRONT MARKER/TURN LIGHTS AND REAR TURN LIGHTS TO FLASH IN A MANNER SIMILAR TO HAZARD WARNING, RATHER THAN FLASHING ON THE DESIRED SIDE ONLY.
Consequence & remedy
Consequence: THE DRIVER MAY NOT BE ABLE TO CLEARLY SIGNAL THEIR INTENTIONS TO TURN, CHANGE TRAVEL LANES, OR POTENTIALLY WARN OTHERS OF AN IMPAIRED VEHICLE OPERATING CONDITION INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE SUSPECT FLASHER MODULES WITH A NEW FLASHER MODULE DESIGNED WITH SEALED RELAYS AND MORE DURABLE CONTACT MATERIAL INSIDE OF THE RELAYS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 4, 2005. ISUZU BEGAN MAILING OWNER LETTERS ON AUGUST 4, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, ISUZU AT 1-800-255-6727, BUICK AT 1-866-608-8080, AND OLDSMOBILE AT 1-800-630-6537.

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.
BY LETTER DATED APRIL 29, 2005, GM NOTIFIED THE AGENCY THAT IT IS CONDUCTING ASAFETY RECALL ( NHTSA RECALL NO. 05V198 ) INVOLVING CERTAIN MODEL YEARS (MY) 2003-2004 ISUZU ASCENDER, CHEVROLET TRAILBLAZER, GMC ENVOY, OLDSMOBILE BRAVADA AND MY 2004 BUICK RAINER VEHICLES.THE RECALL APPLIES TO VEHICLES BUILT FROM APRIL 2003 THROUGH NOVEMBER 2003 FOR A TOTAL VEHICLE POPULATION OF 286,478.GM REPORTS THE DIRECTIONAL/HAZARD SIGNALS FAILURE IS DUE TO STICKING CONTACTS ON ROUTING RELAYS IN THE FLASHER MODULE.GM WILL REPLACE THE FLASHER MODULE ON ALL INVOLVED VEHICLES.BASED ON GM'S SAFETY RECALL ACTION, THIS INVESTIGATION IS CLOSED.
