GMC USED CHEAP BOLTS ON THEIR V8 MOTOR'S EXHAUST MANIFOLDS. I HAVE TWO BROKEN BOLTS ON ONE SIDE AND 1 ON THE OTHER. CARR OF VANCOUVER GAVE ME A QUOTE OF $ 2374.00 PLUS TAX TO FIX THIS PROBLEM. THEY SAID IT WAS A WELL KNOWN PROBLEM WITH ALL OF THE V8 MOTORS BY GMC. I CONTACTED GMC AND THEY REFUSE TO DO ANYTHING ABOUT THIS. I HAVE RESEARCHED IT ON THE INTERNET AND THERE ARE HUNDREDS OF PEOPLE WHO HAVE HAD THIS SAME PROBLEM. THE QUESTION ISN'T IF THIS WILL HAPPEN TO ONE OF THEIR VEHICLES BUT WHEN IT WILL HAPPEN. IT IS SUCH A WIDE AND KNOWN PROBLEM A COMPANY HAS ACTUALLY MADE CAME OUT WITH A BRACKET TO FIX THIS PROBLEM. I DON'T FEEL THAT THIS SHOULD BE A CONSUMER PROBLEM BUT IT SHOULD BE A MANUFACTURER PROBLEM. I WOULD APPRECIATE ANY HELP. I FEEL THAT THEY SHOULD HAVE TO RECALL THESE DEFECTIVE BOLTS AND REPLACE THEM WITH THE RIGHT ONES. I AM NOT OUT FOR ANY KIND OF SETTLEMENT OR SCAM ALL I WANT IS MY ENVOY FIXED. KRAL AUTO PARTS MAKES THE BRACKET. HTTPS://WWW.KRALAUTOPARTS.COM. *TR

THE SERVICE AIR BAG LIGHT IS ALWAYS ON. WHEN IT WAS PURCHASED THE LIGHT WAS OFF. IT WAS TAKEN IN FOR SERVICE BACK TO THE DEALER BEFORE THE 30 DAY WARRANTY WAS UP DUE TO RADIO ISSUES (BUZZ) THEY WORKED UNDER THE BACK SEAT ON A DEVICE AND UNDER THE DASH BELOW THE STEERING COLUMN TO RESOLVE. THE SOUND RETURNED AND THEY REPLACED A PART UNDER THE BACK SEAT. A FEW MONTHS LATER THESE NEW ISSUES STARTED. THE SERVICE AIR BAG LIGHT IS ALWAYS ON RECENTLY THE SERVICE STABILITY CONTROL LIGHT HAS STARTED. THIS IS INTERMITTENT. PLEASE ADVISE. FYI: THERE IS A FEW BULLETIN BOARDS WHERE A LOT OF OTHER PEOPLE ARE EXPERIENCING THE SAME ISSUES. *TR

OUR 2008 GMC ENVOY KEPT ON GETTING LOUDER AND LOUDER AS TIME WENT ON AND WHEN I WENT TO CHECK IT OUT I FOUND THAT THE EXHAUST MANIFOLD HAD A CRACK IN IT ABOUT 3.5 INCHES LONG. IF FEEL THAT THIS SHOULD BE A RECALL DO TO I CHANGED 3 OD THEM IN OTHER GMC ENVOYS IN THE LAST 6 MONTHS. I OWN A STATE INSPECTION REPAIR GARAGE IN PENNSYLVANIA.THIS IS A VERY POOR LAYOUT BY GM. ALSO THE SECONDARY AIR PUMP ON THIS SAME VEHICLE IS A COMMAND PROBLEM. AND THE WIPER SPRAY NOZZLE IS ALSO ANOTHER COMMAND POOR DESIGN. *TR

IN JANUARY, 2012, AFTER A DAY OF MAKING SEVERAL STOPS (CHURCH, VISIT FAMILY, MOVIE), WE STOPPED FOR A LATE NIGHT DINNER). THE RESTAURANT WAS CLOSING, SO WE RETURNED TO THE VEHICLE IN LESS THAN 5 MINUTES. WHEN WE RETURNED TO THE VEHICLE, THE CAR WOULD NOT START. AFTER SEVERAL UNSUCCESSFUL ATTEMPTS, WE HAD TO HAVE THE TRUCK TOWED. SINCE IT WAS LATE NIGHT, WE HAD TO HAVE THE VEHICLE TOWED TO THE HOME AND THEN TO A REPAIR SHOP. AFTER BEING IN THE REPAIR SHOP FOR SEVERAL DAYS AND AFTER SEVERAL DIAGNOSTIC TESTS,, WE WERE TOLD THE IGNITION SWITCH WAS REPLACED. SINCE THIS 1ST INCIDENT IN 2012, THIS HAS OCCURRED AT LEAST 10 TIMES. AFTER ONE INCIDENT IN 2013, WE BOUGHT A NEW BATTERY. AFTER 2 WEEKS, THE NEW BATTERY WAS DEAD AND WE RECEIVED A NEW BATTERY. HOWEVER, THE VEHICLE NOT STARTING OCCURRED AT LEAST ANOTHER 3 TIMES. AFTER REPLACING THE BATTERY TWICE, WE HEARD THERE WAS AN IGNITION SWITCH RECALL FOR GMC VEHICLES. WHEN I CONTACTED GM, THEY TOLD ME THE RECALL WAS FOR OTHER MAKES AND MODELS, BUT NOT ON THE ENVOY. MY CONCERN IS WE DON'T KNOW WHEN THE CAR WILL START OR NOT. WE HAVE ALSO HAD THE STARTER CHECKED SEVERAL TIMES & WAS TOLD IT'S NOT THE STARTER. IT APPEARS NO ONE IS ABLE TO DETERMINE WHY THE VEHICLE DOES NOT START AND WHEN IT WILL HAPPEN. I AM CONCERNED FOR MY SAFETY - WHEN IT'S GOING TO HAPPEN, WHERE WILL I BE., IF I AM CLOSE TO HOME OR NOT AND WILL WE HAVE TO INCUR ANOTHER TOWING CHARGE. *TR

1RQ17002 · 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.
