WHO ARE WE KIDDING WITH THIS RECALL? (NHTSA 14V355, GM 14299) CORRECTING A FAULTY IGNITION SWITCH WITH AN EXTRA KEY RING AND A PAPER TO ADD TO THE OWNER'S MANUAL IS A LAWYER'S SOLUTION. IS THIS A DESIGN DEFECT, OR IS IT NOT? WHY IS IT NOT ADEQUATE? 1) IT DOES NOT INSURE THAT THE WEIGHT OF THE KEYS WILL NOT CAUSE SHUTDOWN. IT ONLY MAKES IT A LITTLE LESS LIKELY. 2) IN A YEAR'S TIME, EVEN THE CURRENT OWNER'S WILL HAVE FORGOTTEN THE SOLUTION. EVEN IF IT'S IN THE CAR'S MANUAL, DOES ANYONE EVER ACTUALLY READ THE MANUAL END-TO-END?. LET ALONE REREADING IT REGULARLY TO REFRESH THEIR KNOWLEDGE? IT'S ONLY THERE, IF AT ALL, FOR REFERENCE. 3) HOW MANY SECOND OWNER'S EVEN GET THE MANUAL? HOW MANY WILL GET KEYSETS WITH THE EXTRA RING? MY EXPERIENCE IS FEW, IF ANY, SUBSEQUENT OWNERS WILL HAVE ANY REMINDER OF THIS RECALL. LET'S GET SERIOUS AND BE RESPONSIBLE. IF THERE IS A DESIGN OR MANUFACTURING SAFETY DEFECT, THEN FIX IT! DEFLECTING LIABILITY TO THE OWNER IS HORSE-PUCKY! *TR

WE WERE STOPPED AT A RED LIGHT AND THE CAR JUST DIED. WE CALLED AAA AND BEFORE THEY GOT THERE THE CAR STARTED UP AGAIN. THEN WE RECEIVED A RECALL NOTICE FROM GM (RECALL #14299). SINCE PARTS ARE NOT AVAILABLE ACCORDING TO THE LETTER WE REMOVED EVERYTHING FROM THE KEYCHAIN LEAVING ONLY ONE SINGLE KEY AS INSTRUCTED. HOWEVER, OUR CAR AGAIN DIED ON AUGUST 21, 2014 BUT AFTER A FEW MINUTES STARTED UP AGAIN. TODAY, AUGUST 31, 2014 OUR BUICK DIED AGAIN IN THE LEFT TURN LANE STOPPED AT A RED LIGHT. WE HAD TO BE TOWED HOME BY AAA BECAUSE IT WOULD NOT START AGAIN. THIS IS UNACCEPTABLE!! WE ARE AN 80 YEAR OLD COUPLE AND WE ONLY HAVE THIS ONE CAR FOR TRANSPORTATION. WE CANNOT KEEP WORRYING ABOUT OUR CAR EVERYTIME WE DRIVE IT, MUCH LESS THE DANGERS OF HAVING AN ACCIDENT WHEN IT STALLS IN THE MOST UNEXPECTED PLACES AND TIMES. WE NEED A RENTAL CAR TO USE UNTIL GM CAN GET THESE PARTS. I DON'T THINK THAT I AM ASKING TOO MUCH. *TR

Official recalls
315V519000 · Exterior Lighting:headlights
Aug 14, 2015
General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
Consequence & remedy
Consequence: Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.
14V355000 · Electrical System:ignition
Jun 23, 2014
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence & remedy
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.
06V419000 · Fuel System, Gasoline:storage
Oct 31, 2006
ON CERTAIN VEHICLES, THE FUEL TANK IS MISSING THE ADHESIVE LAYER THAT BONDS THE BARRIER LAYER TO THE OUTER SHELL OF THE FUEL TANK.
Consequence & remedy
Consequence: WITH THIS CONDITION, FUEL AND/OR FUEL VAPORS COULD SEEP OUT BETWEEN THE LAYERS, INCREASING THE RISK OF A FIRE.
Remedy: DEALERS WILL INSPECT THE SERIAL NUMBER ON THE FUEL TANK AND REPLACE THE FUEL TANK IF NECESSARY. THE RECALL BEGAN ON NOVEMBER 13, 2006. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CHEVROLET AT 1-800-630-2438, OR PONTIAC AT 1-800-620-7668.

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.
