THE CLUSTER PANEL WAS REPLACED WITH NO LUCK OF THE PROBLEM BEING RESOLVED. FUSES WERE REPLACED ALSO. THIS IS NOT ONLY UPSETTING BUT IT IS ALSO DANGEROUS. I CAN NOT AND DO NOT DRIVE THE CAR BECAUSE OF THIS ISSUE. HOW DO I KNOW HOW MUCH GAS I HAVE OR HOW FAST I AM TRAVELING. AFTER DOING SOME RESEARCH, THIS IS A PROBLEM THAT HAS COME UP BEFORE WITH NO SOLUTION. SOMETHING NEEDS TO BE DONE ABOUT THIS ISSUE.

Official recalls

15V519000 · 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.

06V417000 · Air Bags:frontal

Oct 31, 2006

CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.

Consequence & remedy

Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.

Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.

05V156000 · Service Brakes, Hydraulic:pedals And Linkages

Apr 20, 2005

ON CERTAIN PASSENGER VEHICLES, THE CLIP THAT SECURES THE BRAKE PUSHROD TO THE BRAKE PEDAL ARM PIN COULD HAVE BEEN BENT WHEN IT WAS INSTALLED. A BENT CLIP MAY COME OFF, ALLOWING THE BRAKE BOOSTER PUSHROD TO SEPARATE FROM THE BRAKE PEDAL.

Consequence & remedy

Consequence: PUSHING ON THE PEDAL WILL NOT APPLY THE BRAKES AND A VEHICLE CRASH COULD OCCUR WITHOUT PRIOR WARNING.

Remedy: DEALERS WILL INSTALL A NEW BRAKE PEDAL PUSH ROD BUSHING AND RETAINING CLIP AND, IF THE CLIP WAS MISSING, A NEW BRAKE PEDAL ARM ASSEMBLY FREE OF CHARGE. THE RECALL BEGAN ON APRIL 26, 2005. OWNERS MAY CONTACT BUICK AT 1-866-608-8080.
