I PURCHASED MY 2004 ENVOY XUV NEW. I LOVE IT, BUT THE SPEEDOMETER HAS BEEN GETTING PROGRESSIVELY WORSE. I GUESS I'VE BEEN ONE OF THE LUCKY ONES.

I PURCHASED MY 2004 ENVOY XUV NEW. I LOVE IT, BUT THE SPEEDOMETER HAS BEEN GETTING PROGRESSIVELY WORSE. I GUESS I'VE BEEN ONE OF THE LUCKY ONES. THE BRAKES ARE FINE AND EVERYTHING ELSE SEEM TO BE OK SO FAR. I CURRENTLY HAVE 89,000 MILES ON IT AND THE FREQUENCY OF THE SPEEDO ACTING UP ARE GETTING MORE COMMON. I REMEMBER THE FIRST TIME WAS LATE IN '07. THE SPEEDO JUST KEPT CLIMBING HIGHER AND HIGHER TILL IT WAS PINNED. AND STAYED THERE FOR A DAY OR TWO. IT WOULD READ 120 MPH PARKED IN THE GARAGE. I BROUGHT IT IN AND THE DEALER JUST ROLLED THEIR EYES AND SAID THEY COULD ORDER ANOTHER DASH BOARD FOR AROUND $500.00, BUT I OPTED NOT TO FIX IT AT THAT TIME. THE DEALER TOLD ME IT WAS A COMMON THING WITH THE ENVOY, BUT GM HAS NO RECALLS ON IT. IT HAD SEEMED FINE FOR A WHILE. THEN IT HAPPENED AGAIN A FEW TIMES IN '08. NOW IT'S ONLY MARCH OF '09 AND IT HAS HAPPENED AT LEAST ONCE EVERY TWO WEEKS. IT IS CLEARLY OUT OF WARRANTY BUT BEING A SAFETY ITEM SUCH AS A INSTRUMENT CLUSTER ONE WOULD THINK IT WOULD BE A RECALL ITEM. THIS APPEARS TO BE A NATION WIDE ISSUE AND GM AND THE DOT / NHTSA DO NOT RECOGNIZE IT? I LIKE THE VEHICLE, I AM HAPPY WITH IT OTHERWISE. JUST DISAPPOINTED AND FRUSTRATED WITH THE NHTSA AND GM. *TR

WE HAD TO USE THE SPEEDOMETER ON THE TOMTOM TO DETERMINE OUR CORRECT SPEED SINCE THE SPEEDOMETER WAS READING 5-10 OVER THE SPEED LIMIT. AFTER THE VEHICLE SAT FOR THE NIGHT, IT STARTED WORKING AGAIN...BUT ONLY TO STOP AGAIN 1/2 WAY THROUGH OUR TRIP BACK HOME. I HAVE NOTICED THAT THIS HAS HAPPENED TO THE SPEEDOMETER ON MORE THAN ONE OCCASION AND REFUSE TO PAY THE OUTRAGEOUS AMOUNT TO REPAIR IT. I THINK THIS IS A MANUFACTURER DEFECT AND SHOULD BE TAKEN CARE OF BY THEM. *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.
