I HAVE NOTICED THAT WHEN DECELERATING & APPLYING MY BRAKES WHEN APPROACHING A STOP THAT MY VEHICLE ACTUALLY WILL ACCELERATE ALL OF THE SUDDEN. THIS HAS HAPPENED ON SEVERAL OCCASIONS, NOT ALWAYS, BUT ENOUGH FOR ME TO BE CONCERNED. MY DAUGHTER ALSO EXPERIENCED THIS SUDDEN ACCELERATION WHEN SHE WAS DRIVING MY SUBURBAN. SHE, LIKE ME, SAID IT HAPPENED WHEN SHE WAS APPROACHING A STOP SIGN AND WAS APPLYING BRAKE PRESSURE. THIS SHOULD BE INVESTIGATED. *TR

A SMALL CRACK BEGAN ON THE DRIVER SIDE OF DASH BOARD. WITHIN WEEKS, THE CRACK BECAME MUCH BIGGER. AFTER TWO MORE WEEKS, I NOTICED ANOTHER CRACK ON THE PASSENGER SIDE OF THE DASH. SOON, IT BECAME MUCH LARGER TOO. NOW, THERE ARE SEVERAL CRACKS ON THE DASHBOARD. THIS AUTOMOBILE WAS NOT INVOLVED IN ANY TYPE OF ACCIDENT OR DRIVING ON ROUGH TERRAIN. I DON NOT UNDERSTAND WHY THE DASHBOARD WOULD CRACK. I HAVE NEVER OWNED A VEHICLE WHICH HAS HAD THIS HAPPEN. *TR

THIS IS BECOMING A RECURRING AND REPRODUCIBLE PROBLEM. THE UNINTENDED ACCELERATION OCCURS WHILE SLOWING DOWN FOR A STOP SIGN AND DEPRESSING THE BRAKE PEDAL. THE MOST RELIABLE WAY TO REPRODUCE THE PROBLEM IS AS FOLLOWS. BE DRIVING ABOUT 15 MILES PER HOUR, UP A SLIGHT SLOPE. MOVE YOUR FOOT OFF THE ACCELERATOR PEDAL AND ON TO THE BRAKE PEDAL. DEPRESS THE BRAKE LIGHTLY. JUST AS THE VEHICLE STARTS TO SLOW DOWN YOU WILL FEEL THE ACCELERATION OF THE ENGINE AS IF THE VEHICLE IS ATTEMPTING TO MAINTAIN THE 15 MILE PER HOUR PREVIOUS SPEED. THIS UN…

WHILE DRIVING ON THE HIGHWAY I WAS USING THE CRUISE CONTROL AND THE CAR BEGAN TO INCREASE IN SPEED WITHOUT MY CONTROL. IT WENT FROM 65 TO 90 IN A FEW SECONDS AND I HAD TO SLAM ON THE BREAKS TO GET IT TO STOP. THIS HAS HAPPENED SEVERAL TIMES. ALSO WE CAN NEVER LET THE GAS GET LOWER THEN A QUARTER OF A TANK OR THE CAR JUST SHUTS DOWN LIKE ITS EMPTY. SOMETIMES THE ENGINE WILL JUST REV UP FOR NO REASON AND OTHER TIMES IT DOESN'T ACCELERATE PROPERLY. YOU CAN PUSH THE GAS AND IT FEELS LIKE THE SPEED IS DELAYED BUT THEN WILL CATCH UP. *JS

Reported: 2014-12-30 (December 30, 2014)

General Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.

Consequence: If stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.

Remedy: GM will notify owners, and dealers will inspect and replace the ignition lock housing, as necessary, free of charge. The recall began on February 12, 2015. Owners may contact GM customer service at 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14696 for the original equipment, and 14912 for the service replacement parts.

General Motors, LLC (GM) is recalling certain 2007-2011 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, Yukon XL, and 2009-2011 Chevrolet Silverado 2500, Silverado 3500, GMC Sierra 2500 and Sierra 3500 vehicles originally sold, or ever registered, in the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands or "Zone A."

These vehicles are equipped with non-desiccated passenger frontal inflators containing phase-stabilized ammonium nitrate (PSAN) propellant. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.

Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.

Remedy: GM will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. Interim letters notifying owners of the safety risk were mailed on February 22, 2021. Second notification letters will be mailed once the remedy is available. Owner notification letters were mailed on March 1, 2021.
