THE SPEEDOMETER DOES NOT READ THE CORRECT SPEED. SOMETIMES WHILE TRAVELING AT 55MPH IT WILL STATE I AM ONLY GOING 40 WHILE OTHER TIMES IT WILL STATE I AM GOING 120. SOMETIME WHEN I START MY VEHICLE THE NEEDLE WILL READ BELOW 0 AND OTHERS IT WILL READ OVER 80 WHILE JUST IDLING. THIS ON TOP OF THE GAS GAUGE NOT READING ACCURATELY, STATING I AM ALMOST OUT OF GAS AFTER I JUST FILLED IT TELLS ME THERE IS SOMETHING MAJORLY WRONG WITH THE ELECTRONICS ON THIS MAKE. ALL I HAD TO DO WAS PUT IN THE WORDS "2005 BUICK RAINIER SPEEDOMETER GAS GAUGE FAILURE" AND FOUND WAY TO MANY INCIDENTS OF THE SAME PROBLEM. I CONTACTED BUICK AND THEY ARE GOING TO SEND ME TO HAVE IT LOOKED AT, I HAVE A FEELING THEY ARE GOING TO CHARGE ME. AND I THINK IT SHOULD BE THEIR RESPONSIBILITY SINCE IT SEEMS TO BE A PREVALENT ISSUE AND MY VEHICLE ONLY HAS 60K MILES ON IT FOR AN ALMOST 8 YEAR OLD CAR. IF I HAVE TO PAY FOR IT, IT WILL BE THE LAST GM CAR I PURCHASE. ESPECIALLY SINCE MY GRAND DAUGHTER IS GETTING OF DRIVING AGE AND I WANTED TO PASS THIS ON TO HER. *TR

THE SPEEDOMETER HAS BEGUN REGISTERING SIGNIFICANTLY HIGHER SPEEDS THAN THE VEHICLE IS TRAVELING. AT ONE POINT, A GPS DEVICE IN THE VEHICLE INDICATED A SPEED OF 55, AND THE SPEEDOMETER FOR THE VEHICLE REGISTERED MORE THAN 100 MPH.

THE SPEEDOMETER HAS BEGUN REGISTERING SIGNIFICANTLY HIGHER SPEEDS THAN THE VEHICLE IS TRAVELING. AT ONE POINT, A GPS DEVICE IN THE VEHICLE INDICATED A SPEED OF 55, AND THE SPEEDOMETER FOR THE VEHICLE REGISTERED MORE THAN 100 MPH. IN OTHER CASES, WHEN STANDING STILL, THE SPEEDOMETER SHOWED A SPEED OF 35 MPH. SUBSEQUENTLY, AND INTERMITTENTLY, THE SPEEDOMETER WORKS CORRECTLY, AND THEN REVERTS TO DEFECTIVE MODE. GM ADVISED THAT THE VEHICLE WAS OUT OF WARRANTY AND THAT THE COST OF REPAIR WOULD HAVE TO BE BORNE BY THE VEHICLE OWNER, EVEN IF IT WAS A SAFETY ISSUE. A GM DEALER IN VERMONT INDICATED THAT THE ENTIRE "BUNDLE" FOR THE INSTRUMENT PANEL WOULD HAVE TO BE REPLACED. WHEN GIVEN THE OK TO PROCEED, THE DEALERSHIP SAID THAT NEW BUNDLES WERE NO LONGER AVAILABLE, AND REBUILT BUNDLES WOULD HAVE TO BE USED - AND NONE WERE CURRENTLY AVAILABLE. THEY SUGGESTED LEAVING THE VEHICLE, REMOVING THE BUNDLE AND SENDING IT AWAY FOR REBUILDING, AND THEN INSTALLING IT BACK INTO THE VEHICLE. I DECLINED THAT OFFER. THE DEFECTIVE SPEEDOMETER PROBLEM CONTINUES TODAY, AND I HAVE TO BELIEVE THAT THE UNAVAILABILITY OF NEW BUNDLES, IF CORRECT, MEANS THAT THIS IS LIKELY A WIDESPREAD PROBLEM AND POTENTIALLY MAJOR SAFETY ISSUE. *TR

I RECENTLY WAS DRIVING MY VEHICLE WHEN I REALIZED THE SPEEDOMETER WAS INCORRECTLY WORKING. FOR A FEW DAYS IT WAS ACTING UP THEN STOPPED WORKING ALL TOGETHER. THEN A WEEK OR SO LATER THE GAS GAUGE READS EMPTY WHEN I HAD JUST FILLED IT. I AM VERY CONCERNED WITH THESE MATTERS FOR I USE THIS VEHICLE TO TRANSPORT 3 VERY SMALL CHILDREN AND BOTH ISSUES ARE VERY UNSAFE. I READ NOW THAT THERE ARE SEVERAL OTHER COMPLAINTS WITH THESE MATTERS ALONG WITH SEVERAL OTHER ISSUES WITH THE SAME MAKE OF VEHICLE. I WOULD THINK THAT GM WOULD OFFER A RECALL ON THESE ISSUES BECAUSE THEY ARE BOTH VERY EXPENSIVE TO HAVE FIXED. WHEN I PRICED THE SPEEDOMETER CLUSTER MY MECHANIC WANTED OVER 500.00 TO FIX AND I CURRENTLY CAN NOT AFFORD THESE COSTS DUE TO BEING OUT OF WORK ON MEDICAL LEAVE. *JS

SINCE THE SPEEDOMETER STOPPED WORKING HALF OF THE DASH BOARD LIGHTS NOW NO LONGER WORK, NEITHER POWER SEAT WORK AND LAST WEEK THE POWER WINDOWS IN THE BACK SEAT STOPPED WORKING. OBVIOUSLY THERE IS A MAJOR PROBLEM WITH THE ELECTRICAL SYSTEM IN THIS MAKE/MODEL BECAUSE WE ARE NOT THE ONLY ONES WITH THESE PROBLEMS. *TR

THE SPEEDOMETER BEGAN STICKING AT NIGHT. WE KEPT DRIVING THE CAR USING THE RPM GAUGE TO TRY TO JUDGE SPEED. THE SPEEDOMETER WOULD WORK SPORADICALLY. IT NOW DOESN'T WORK. IT SHOW 100 MPH WHEN YOU MAY BE GOING 20 OR IT SHOWS 20 MPH WHEN YOU ARE GOING 60. LAST NIGHT WE WERE SHOWING 45 MILES AN HOUR PARKED IN THE DRIVEWAY. THIS IS DEFINITELY NOT A SAFE WAY TO DRIVE A CAR. I KNOW THAT GM HAS HAD PROBLEMS WITH THIS AND HAS RECALLED SOME TRAILBLAZERS AND TAHOES, BUT SO FAR THEY HAVE NOT DONE ANYTHING TO HELP THE RAINIER OWNERS. THIS IS A COSTLY REPAIR AND IT IS CAUSED BY A NEW DESIGN GM TRIED. *TR

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.
