ON 1/23/2011 I WAS ON A TRIP, 77 MILES FROM HOME, WHEN MY 2004 CHEVY TRAILBLAZER'S INSTRUMENT PANEL WENT CRAZY. I THOUGHT MY ENGINE WOULD BLOW BECAUSE THE RPM GAUGE WENT OFF THE CHARTS, THEN WOULDN'T READ ANYTHING. THEN MY SPEEDOMETER DID THE SAME. I HAD NO IDEA HOW FAST I WAS GOING, ON THE INTERSTATE. I WAS WORRIED, SO I MOVED TO THE LEFT LANE, AND STAYED BEHIND THE SLOWER TRAFFIC TO BE SAFE. WHEN I GOT HOME, I STOPPED AT MY LOCAL CHEVY DEALERSHIP WHERE I WAS TOLD THAT ALMOST EVERY TRAILBLAZER OVER 80,000 MILES IS HAVING THE SAME ISSUES. THE PROBLEM COULD BE MY INSTRUMENT PANEL COMPUTER, OR ONE OF SEVERAL BAD MODULES. THE CAN DOES NOT SHOW ANY ERROR CODE, SO THE COST TO REPAIR RANGES FROM $600 TO OVER $1500 DEPENDING ON HOW LONG IT TAKES YOUR REPAIR PERSON TO FIND THE PROBLEM. AFTER MY DIAGNOSIS I WAS ANGRY, I AM TIRED OF REPAIRING ITEMS ON THIS CAR. I WENT ONLINE TO SEE IF IT WAS RARE, OR IF ANYONE ELSE HAD THE PROBLEM, AND AN EXACT REPAIR. ON ONE WEBSITE ALONE ABOUTAUTOMOBILE.COM I FOUND OVER 1,300 TRAILBLAZER OWNERS WITH THE SAME PROBLEM. AFTER FURTHER RESEARCH I HAVE FOUND ALMOST 19,000 TRAILBLAZER COMPLAINTS ABOUT THE SAME PROBLEM. I DO BELIEVE THAT ALL TRAILBLAZERS WILL HAVE THIS ISSUE, AND THAT GM SHOULD FIX IT, WITH A RECALL REPAIR. I HAVE SENT COMPLAINTS TO GM, BUT NO RESPONSE HAS BEEN GIVEN. *TR

MY SPEEDOMETER FAILED AND READS ANYTHING IT WANTS. YOU CAN BE DOING 25MPH AND IT WILL READ 110MPH OR YOU CAN BE DOING 60MPH AND IT WILL REGISTER 45MPH. THERE ARE A MILLION COMPLAINTS ON THE INTERNET ABOUT GM SPEEDOMETERS AND OTHER INSTRUMENT CLUSTERS FAILING. I THINK THIS IS A SAFETY CONCERN AND SHOULD BE INVESTIGATED. GM IS JUST PASSING THE BUCK WHEN YOU ASK FOR HELP. JUST GO TO GOOGLE AND ASK FOR GM INSTRUMENT CLUSTER FAILURE AND COUNT THE COMPLAINTS.

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.
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.

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.
