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.

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…
AIR BAGS06V4170002006-10-31794 affected
Defect
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
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…
SERVICE BRAKES, HYDRAULIC05V1560002005-04-2061,594 affected
Defect
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
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.
