Adaptive cruise control dropped out, taking along with it the ABS (warning light), Stabilitrak (handling system) (warning light), Collision prep (message). Dealer states the ABS computer module failed, now in process of finding a replacement. Meanwhile, the ABS, cruise control, and other systems mentioned here are inoperative. It may well be that this may be considered to be a component failure, not an inherent safety issue but under some driving conditions it is clearly a safety consideration.

THIS IS TO AMEND COMPLAINT NUMBER 11051891. CAUSE OF UNINTENDED ACCELERATION WAS AFTERMARKET FLOOR MAT INSTALLED BY THE BUICK DEALER! FLOOR MAT HAS DIAGONAL GROOVES MOLDED INTO THE RUBBER IN EXACTLY THE WORST SPOT SUCH THAT THE CORNER OF ACCELERATOR PEDAL CATCHES IN THE GROOVE AND HOLDS THE THROTTLE WIDE OPEN. I GUESS THEY DIDN'T LEARN FROM THE TOYOTA / LEXUS DISASTERS AND DARN NEAR KILLED ME IN THE PROCESS!

FROM STANDING STOP OR WHILE IN MOTION AT HIGHWAY SPEEDS, STOMP THE ACCELERATOR TO COMMAND IMMEDIATE ACCELERATION: ACCELERATOR SOMETIMES STICKS IN WIDE OPEN THROTTLE RESULTING IN UNINTENDED SUSTAINED ACCELERATION. FIRST COUNTER-MEASURE TRIED - SLAP THE GEAR SELECTOR HANDLE TO NEUTRAL POSITION; HOWEVER, ENGINE REMAINS IN WOT CONDITION. SECOND COUNTER-MEASURE - PUSH THE ENGINE OFF SWITCH AND COAST TO A STOP. THIRD COUNTER-MEASURE - STOP THE ACCELERATOR PEDAL AGAIN UNTIL IT COMES UN-STUCK. IN LIGHT OF THE EFFECTIVENESS OF COUNTER-MEASURE #3, I BELIEVE THE FAULT IS IN THE LINKAGE FROM THE ACCELERATOR PEDAL TO THE THROTTLE CONTROL - PROBABLY IN THE ACCELERATOR PEDAL LINKAGE ITSELF.
