DRIVING DOWNHILL A TRUCK PULLING A TRAILER BRAKE SUDDENLY IN FRONT OF ME CAUSING ME TO HAVE TO BRAKE HARD. THE BRAKE PEDAL SHUDDERED AND FELT LIKE I NEEDED TO TAKE MY FOOT OFF THE BRAKE BUT I COULDN'T! ADDITIONALLY THE STEERING WHEEL SHUDDERED HORRIBLY SIDE TO SIDE. BRAKING ON THE REMAINDER OF THE HILL AND FOR A WHILE AFTER HAD THE SAME CHATTERING, SHAKING, SHUDDERING, AND SORT OF BRAKE GRINDING FEELING MAKING ME FEEL LIKE I COULD NOT RELY ON THE BRAKES AND MAYBE THE STEERING WAS HAVING PROBLEMS TOO. SCARED ME AND FELT TERRIBLY UNSAFE!!!! THIS HAPPENED ONCE BEFORE ABOUT A YEAR AGO WITH THIS CAR IN A SIMILAR DOWNHILL SUDDEN BRAKING SITUATION. I DRIVE TO AVOID HAVING TO BRAKE SUDDENLY BUT SOMETIMES IT IS UNAVOIDABLE AND I DON'T WANT TO DRIVE THIS CAR ANYMORE BECAUSE IT FEELS TOO UNSAFE. *TR
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.
General Motors (GM) is recalling certain model year 2008-2012 Chevrolet Impala police vehicles because the front lower control arms may fracture. This safety recall does not include non-police Chevrolet Impala vehicles.
Consequence & remedy
Consequence: A broken control arm can result in the loss of control of the vehicle, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace both front lower control arms, free of charge. The safety recall began on August 21, 2012. Owners may contact the Chevrolet owner center at 1-866-694-6546.
