HELLO, I PURCHASED A 2005 ENVOY DENALI LAST YEAR. RIGHT AFTER I GOT THE VEHICLE THE FUEL LEVELING SENSOR CAME ON (I THINK 1 OF EVERY 2 GET THIS PROBLEM AND STILL NO RECALL). I LET IT GO BUT NOW ITS TIME FOR INSPECTION! WELL WITH THE LIGHT ON IT CANNOT BE INSPECTED AND THEY ARE CHARGING ME WITH WHAT THEY SAID COULD BE WELL OVER $700. I WAS DOING SOME RESEARCH AND FOUND THIS SITE OF MANY HTTP://WWW.TOPIX.COM/FORUM/AUTOS/CHEVROLET-TRAILBLAZER/TH8JI6TEPO3VRJI3D/P2 OF PEOPLE WHO ARE HAVING THIS SAME PROBLEM. I WISH THEY WOULD STAND BY THERE PRODUCT AND HAVE A RECALL OF THIS BECAUSE ITS REALLY A HUGE PROBLEM IF I'VE EVER SEEN ONE. I AM NOT SAYING THIS JUST BECAUSE I HAVE THIS PROBLEM BUT MANY MANY PEOPLE DO. DO A EBAY LIST FOR AN ENVOY AND I GUARANTEE YOU THAT YOU'LL SEE ALMOST HALF IF THEY SHOW YOU THE DASH BOARD HAS THIS PROBLEM. I DID NOTHING WRONG BUT FILL UP MY TANK AND I GOT THIS ERROR. LET ME KNOW IF ANYTHING IN THE NEAR FUTURE WILL BE DONE. MY INSPECTION IS ALMOST UP AND ITS A MUST TO GET DONE! *TR

THEN 10 MINUTES LATER THE LIGHT GOES OUT AND IT READS THAT I DO HAVE FUEL. THEN A LITTLE LATER IT STARTS GOING DOWN AND READS EMPTY AGAIN. I HAVE RE-STOPPED TO GET GAS TO FIND THAT THE TANK IS FULL. THIS IS WRONG AND THERE SHOULD BE A RECALL ON THIS ITEM. IT DRAWS THE DRIVER'S ATTENTION AWAY FROM DRIVING AND MUST HAVE CAUSED ACCIDENTS SOMEWHERE IN THE USA. *TR

I HAVE A 2005 ENVOY SE AND HAVE BEEN HAVING PROBLEMS WITH MY GAS GAUGE FOR THE PAST YEAR. CURRENTLY THE VEHICLE HAS 80000 MILES ON IT. THE PROBLEM IS WITH THE GAS GAUGE AND IT WILL NOT WORK ANY LONGER. IT SEEMS AS IF LOST PRESSURE AND WILL NOT READ HOW MUCH GAS I HAVE IN THE VEHICLE. WHEN I FILL UP, IT WILL STAY ON EMPTY AND WILL NOT MOVE. AT TIMES, IT WILL GO FROM EMPTY TO ABOUT HALF TANK FOR A FEW MINUTES AND THEN IT WILL DROP ALL THE WAY BACK DOWN TO EMPTY. *TR

RIGHT AFTER THE WARRANTY RAN OUT ON MY 05 GMC ENVOY THE GAS GAUGE STARTED BEEPING WHEN YOU WOULD FILL UP THE TANK. THEN IT STARTED TO NOT READ FULL WHEN IT WAS FILLED. NOW IT NEVER READS FULL AND WHEN THE TANK IS HALF EMPTY THE LIGHT WILL COME ON. IT WILL ALWAYS BEEP WHEN I FIRST START IT. THIS UNIT SHOULD NOT HAVE WENT OUT AFTER 36,000 MILES. THIS IS A FAULTY UNIT AND I BELIEVE THE MANUFACTURER SHOULD REPLACE IT. IF I WAS TO REPLACE IT MYSELF IT WOULD COST ME OVER $500.00 . TERRIBLE PRODUCT TERRIBLE PRODUCT THAT SHOULD BE INVESTIGATED. *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.
