FULL DESTRUCTION BECAUSE OF FIRE I WAS ON THE WAY BACK FROM A LONG TRIP IN SOUTHERN CHILE (UP TO USHUAIA) OVER THE "CARRETERA AUSTRAL" AND, AFTER ABOUT 9'000 KM DRIVE WITHOUT ANY PROBLEM, I SAW A WHITE SMOKE BACK MY VEHICLE. OIL PRESSURE: NORMAL, MOTOR TEMPERATURE: NORMAL. THIS MEANT IMMEDIATE STOP ALONG THE "RUTA 40 NORTE" IN ARGENTINA (ABOUT 100 KM NORTH OF BARILOCHE, ON THE WAY TO NEUQU). WHILE STOPPING, I FELT THE BRAKE PEDAL JUST GOING WITHOUT IMMEDIATE REACTION BUT THE PRESSION CAME BACK. WHILE BRINGING THE GEAR SHIFT TO POSITION PARKING, I DID NOT FEEL ANY SENSATION, AS IF IT WOULD HAVE NO CONNECTION; THE AUTOMATIC DOOR BLOCKER CONNECTED TO THE GEAR SHIFT DID NOT WORK TOO, SO THAT WE HAD TO UNLOCK THE DOORS MANUALLY. AFTER HAVING DISCONNECTED THE ENGINE, I SAW WHITE SMOKE COMING OUT FROM THE UPPER LEFT CORNER OF THE MOTOR. I OPENED THE CAPOT AND THE SMOKE CAME FROM THE LEFT CORNER (CLOSE TO THE DRIVER'S PLACE). SUDDENLY, SOME MATERIAL IN FLAMES FELL TO THE BOTTOM, ABOUT MIDDLE LIGHT LEFT OF THE CAR. I TRIED TO PUT OUT THE FLAMES WITH THE EXTINGUISHER, BUT OTHER BURNING MATERIAL FELL. OTHER PEOPLE HAD STOPPED AND HELPED ME. WE PUSHED THE CAR A LITTLE AHEAD - THOUGH THE HAND BRAKE WAS TIED AND THE GEAR SHIFT ON "P", BUT BURNING MATERIAL FELL AGAIN. IN THE MEANTIME, MY WIFE AND CHILDREN THROW OUT THE LUGGAGE, SO THAT WE COULD SAVE ALMOST ALL OF IT. BUT THE CAR BURNED ENTIRELY. WHAT COULD BE THE REASON OF THIS INCIDENT ? THANKS GOD, I STOPPED IMMEDIATELY SO THAT NOBODY WAS INJURED NOR BURNED AND NO THIRD PARTY SUFFERED ANY DAMAGE. *NM

MY 2004 CHEVROLET, TRAILBLAZER HAS NO TRACTION. I WILL NOT EVEN GO THROUGH WET GRASS.*AK
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.

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.
