1.) NO EVENTS TOOK PLACE DASHBOARD CLUSTER JUST FAILED. 2.) SPEEDOMETER, OIL GAGE, RPM, GAS GAUGE EVERYTHING WENT HAYWIRE, IMPOSSIBLE TO TELL SPEED... 3.)

2005 CHEVY TRAILBLAZER - SPEEDOMETER HAS STOPPED WORKING. SPEEDOMETER READS 100 MPH WHEN SITTING STILL. VERY DANGEROUS SINCE YOU NEVER KNOW HOW FAST YOU ARE GOING. I'VE READ ABOUT THIS SAME COMPLAINT AND GM SHOULD ISSUE A RECALL IMMEDIATELY BEFORE A SERIOUS ACCIDENT HAPPENS. *TR

I WAS DRIVING MY 2005 CHEVY TRAILBLAZER LAST EVENING 4/08/2010 IN TOWN AND MY SPEEDOMETER STARTING SPEEDING UP WITHOUT ME ACCELERATING. AT REST THE SPEEDOMETER SHOWS 45 MPH. THE SPEEDOMETER HAS GONE UP TO 90MPH WHEN I'M TRAVELING AT ABOUT 40 MPH. THE SPEEDOMETER SEEMS TO INCREASE EVEN IF I AM AT A STEADY TRAVELING SPEED. *TR

THE INSTRUMENT CLUSTER PANEL IN MY 2005 CHEVY TRAILBLAZER IS SEVERELY OUT OF WHACK! IT STARTED ABOUT A YEAR AGO WHEN MY SPEEDOMETER TOLD ME I WAS GOING 90 MPH WHEN I WAS ACTUALLY GOING ABOUT 50 MPH. IT EVENTUALLY CORRECTED ITSELF, BUT NOW IT GOES OUT EVERY SO OFTEN WITHOUT WARNING. SINCE THE TIME WHEN THE SPEEDOMETER 1ST WENT OUT, MY OIL GAUGE IS COMPLETELY PEGGED OUT AND WILL NOT CORRECT ITSELF, THE BATTERY GAUGE COMES AND GOES, AS WELL AS THE TEMPERATURE GAUGE. I HAVE BEEN READING FORUMS ABOUT THIS PROBLEM WITH TRAILBLAZERS ALL OVER THE U.S. AND IT SEEMS THAT THERE SHOULD BE A RECALL TO HAVE THE CLUSTER PANEL CORRECTED BECAUSE IT IS AN OBVIOUS PROBLEM WITH THE GM TRAILBLAZERS. IF YOU ASK ME, I BELIEVE IT CAN BE A SERIOUS SAFETY HAZARD WHEN YOU ARE UNCERTAIN AS TO HOW FAST YOU MAY OR MAY NOT BE DRIVING. I HAVE READ WHERE A LOT OF PEOPLE HAVE HAD THEIR GAS GAUGE GO COMPLETELY OUT AS WELL. MINE TRIED TO QUICK WORKING FOR ME ONLY ONE TIME, BUT CORRECTED ITSELF WITHIN 24 HOURS. LET'S HOPE IT DOESN'T GO OUT LIKE THE OIL GAUGE HAS AND THE FLUCTUATING SPEEDOMETER. *TR

GOING DOWN THE INTERSTATE IN MY 2005 CHEVY TRAILBLAZER AND THE SPEEDOMETER SAID I WAS TRAVELING 95 MPH AND PEOPLE WERE PASSING ME LIKE I WAS SITTING STILL. TOOK IT TO THE DEALER AND THERE WAS A RECALL ON THE SPEEDOMETER/ CLUSTER ON EVERY VEHICLE WITH THE SAME SPEEDOMETER EXCEPT THE TRAILBLAZER. NOW I'M FINDING MANY OTHERS WITH THE SAME PROBLEM. GM SAYS THEY WILL TRY TO GET A REDUCED FEE TO GET IT FIXED - NOT GOOD ENOUGH, THEY SHOULD FIX IT FOR NOTHING AS IT IS A SAFETY CONCERN. *TR

2RQ17002 · 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.
