NO REAL EVENTS, THE HINGE BECAME UNGLUED FROM THE REAR WINDOW, CAUSING THE WINDOW TO BECOME UNHOOKED FROM THE BODY OF THE TRAILBLAZER. BECAUSE THIS THEN RAISES THE WINDOW ABOVE THE ROOF OF THE VEHICLE THE WIND CAN CATCH IT AND PULL IT COMPLETELY OFF THE VEHICLE WHEN TRAVELING AT HIGH SPEEDS. *TR

I WAS DRIVING DOWN A CURVY ROAD. I LOOKED AWAY FROM THE ROAD FOR A SECOND AND WHEN I LOOKED BACK TO THE ROAD I WAS SLIGHTLY VEERING OFF. I OVERCORRECTED THE CAR TO MY LEFT AND CORRECTED BACK TO THE RIGHT. ONCE I WAS BACK STRAIGHT AGAIN-THE SIDE IMPACT AIRBAGS DEPLOYED. THIS ALL HAPPENED VERY QUICK. I WAS TRAVELING ABOUT 35-40 MPH. THERE WAS NO DAMAGE TO THE VEHICLE, I DID NOT HIT ANYTHING AND THERE WAS NO COLLISION. THERE WAS ONLY ONE OTHER PASSENGER IN THE CAR AND NO ONE WAS HURT. I CALLED THE INSURANCE COMPANY WHO DECLINED THE CLAIM SINCE THERE WAS NO COLLISION OR PROPERTY DAMAGE. THEY ATTRIBUTED THE CRASH TO OVERLY SENSITIVE YAW SENSORS. THE INSURANCE COMPANY TOLD ME THEY HAVE SEEN SIMILAR OCCURRENCES THAT THEY ATTRIBUTED TO THE YAW SENSOR. I MADE A CLAIM WITH CHEVROLET, THE MANUFACTURER, OF MY VEHICLE. CHEVROLET SENT OUT A 3RD PARTY ENGINEER/INSPECTOR TO LOOK AT AND DIAGNOSE THE VEHICLE. THE ENGINEER'S REPORT SAID THAT THE VEHICLE WAS PREPARING FOR A ROLL OVER AND ACTED AS IT WAS SUPPOSED TO SO THERE WAS NO MECHANICAL MALFUNCTIONS. NOTHING HAS BEEN DONE TO CORRECT THIS SITUATION. THE AIRBAGS ON THE VEHICLE HAVE NOT BEEN REPLACED. CHEVROLET SAYS THE CAR HAS NO MECHANICAL DEFECT AND THE INSURANCE COMPANY SAYS THERE WAS NO COLLISION OR ANYTHING TO ATTRIBUTE TO WHY THE AIRBAGS DEPLOYED, OTHER THAN THE AIRBAGS BEING TOO SENSITIVE. *TR

TL*THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL GAUGE SENSOR FAILED. WHEN FILLING UP THE VEHICLE WITH GASOLINE, THE "FUEL GAUGE EMPTY" WARNING INDICATOR ILLUMINATED ON THE INSTRUMENT PANEL. IN ADDITION, THE FUEL GAUGE WOULD FLUCTUATE AND DISPLAY INCORRECT FUEL LEVELS. THE DEALER STATED THAT THE VEHICLE COULD NOT BE REPAIRED UNDER WARRANTY. THE CONTACT COULD NOT DETERMINE HOW MUCH FUEL WAS IN THE VEHICLE. THE VEHICLE HAS NOT BEEN REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE LESS THAN 51,000. UPDATED 8/18/09 *CN UPDATED 08/21/09.*JB

I AM HAVING PROBLEMS WITH FALSE READINGS WITH MY FUEL GAUGE. LIKE EVERYONE ELSE, I FILL UP MY TANK AND THE GAS GAUGE READS EMPTY, BUT AFTER ABOUT 20 MINUTES IT WOULD READ FULL. NOW IT READS FULL FOR 20 MINUTES AND THEN STARTS TO GO DOWN. I WAS TOLD THAT IS WAS A POSSIBLE SHORT IN THE WIRING AROUND THE FUEL PUMP. GREAT, A GOOD WAY TO START A FIRE!!.. I AM A GM EMPLOYEE OF 14 YRS AND THINK THIS PROBLEM SHOULD BE FIXED AND FIXED NOW. WAY TOO MANY PEOPLE ARE HAVING PROBLEMS WITH THIS ISSUE..... *TR

ON 7/18/09 I FUELED UP MY TRUCK WITH GAS AND THE FUEL GAUGE, WHICH WAS WORKING AT THE TIME QUIT WORKING. I BELIEVE THIS COULD BE A SAFETY ISSUE DUE TO PEOPLE DEPENDING ON THEIR VEHICLES FOR DAY TO DAY LIVE, PLUS THE WAY THE PRICE OF GAS IS PEOPLE CAN'T ALWAYS AFFORD TO STOP AND PUT GAS IN THE VEHICLE. AFTER SEARCHING THE INTERNET I HAVE FOUND NUMEROUS COMPLAINTS ON THIS VERY ISSUE. PLEASE CHECK INTO THIS MATTER BECAUSE THE PRICE OF VEHICLES NOWADAYS IS WAY OUT OF RANGE FOR THE WORKING CLASS PEOPLE. *TR

Official recalls

06V417000 · Air Bags:frontal

Oct 31, 2006

CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.

Consequence & remedy

Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.

Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.

Consequence: IF A CRASH OCCURS, THE WINDSHIELD MAY NOT BE RETAINED, INCREASING THE RISK OF INJURY TO A VEHICLE OCCUPANT.

Remedy: DEALERS WILL REPLACE THE WINDSHIELD FREE OF CHARGE. THE RECALL BEGAN ON MARCH 10, 2005. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CHEVROLET AT 1-800-630-2438, OR GMC AT 1-866-996-9463.

RQ17002 · 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.

DP10001 · Fuel Level Gauge System Failure

Opened Jan 7, 2010 · Closed May 23, 2011

Status: closed (inferred from source dates) · Fuel System, Other; Fuel System, Other:storage:fuel Gauge System

The Office of Defects Investigation has received 668 complaints alleging inaccurate fuel gauge reading while driving in model year 2005-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Saab 9-7x vehicles.Of the 668 complaints, 58 incidents were alleged to result in a vehicle stall.Of the 58 stalling incidents, 43 complaints reported stalling because the fuel level reading indicated more fuel availability than what is actually in the fuel tank. One complaint alleged a vehicle crash after the vehicle stalled while exiting the interstate, became disabled, and was struck from behind.Summarily, the complaints show an apparent increasing trend, with most complaints received within the past year.A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.
