WHILE DRIVING A CONSISTENT SPEED, SPEEDOMETER WILL FLUCTUATE FROM STUCK AT ZERO TO 120MPH. HAPPENS CONSTANTLY. FUEL GAUGE FLUCTUATES ALSO AND DOESN'T ALWAYS WORK. IF USING CRUISE CONTROL WHILE SPEED APPEARS CORRECT, THE IMPALA WILL AUTOMATICALLY INCREASE ITS OWN SPEED WHILE THE SPEEDOMETER DOES NOT CHANGE LEAVING AN UNSAFE OPPORTUNITY OPEN FOR VERY TRAGIC ACCIDENTS TO HAPPEN. I CANNOT BELIEVE THAT MY 2010 PONTIAC VIBE HAS HAD 3 RECALLS AND THIS IMPALA HAS NOT HAD ANY FOR THE INSTRUMENT PANEL. DO PEOPLE REALLY HAVE TO DIE OR BE INJURED BEFORE SOMETHING IS DONE TO PROTECT US? *TR
