THE SPEEDOMETER ON MY 2004 CHEVY IMPALA DOES NOT ACCURATELY TELL WHAT SPEED I AM TRAVELING. IT RANDOMLY STICKS AT A SPEED, SETS THE BASELINE AT A RANDOM SPEED AND READS IN THE 100 MPH RANGE WHEN I AM AT A STOP SIGN OR GOING THROUGH RESIDENTIAL NEIGHBORHOODS. I HAVE NOT FIXED THIS PROBLEM AS THE DEALERSHIP QUOTED A $400 REPAIR AND I CANNOT AFFORD A COSTLY FIX TO A PROBLEM THAT IS NOT MY FAULT. THIS OCCURS ALMOST DAILY AND AT RANDOM TIMES, SOMETIMES DURING SHORT TRIPS, OTHER TIMES DURING LONG TRIPS, BOTH IN THE MORNING AND NIGHT, DOES NOT MATTER HOW FAST I AM TRAVELING OR THE TEMPERATURE OUTSIDE. I LIVE IN NEW ENGLAND AND THIS HAS HAPPENED IN EVERY SEASON. *TR

THE SECURITY LIGHT STARTED COMING ON, AND EVENTUALLY THE CAR BEGAN NOT STARTING. IT STARTED HAPPENING EVERY ONCE IN A WHILE, AND NOW HAPPENS A FEW TIMES A WEEK. THE LIGHTS, RADIO, AND ACCESSORIES WORK, BUT THE CAR WILL NOT START. I HAVE TO WAIT 10 MINUTES TO TRY AGAIN. THIS BEGAN ABOUT A MONTH AFTER MY WARRANTY EXPIRED. I TOOK IT TO A SHOP, WHERE THEY "LOCATED HIGH RESISTANCE IN IGN CYLINDER CONNECTOR TO BODY CONTROL MODULE REMOVED AND CLEANED CONNECTORS AND REPROGRAMMED AS NEEDED". NEXT DAY, SECURITY LIGHT WENT ON, MORNING AFTER THAT, CAR WOULD NOT START! WAS TOLD AT THE SHOP "IF SECURITY LIGHT COMES BACK ON, WILL NEED TO REPLACE TUMBLER AND NEW KEY AND REPROGRAM $690+ TAX". I HAVE A 2-YEAR OLD DAUGHTER THAT I CARE FOR ALL DAY, AND I WORK NIGHTS- LEAVING WORK AT 1:30 A.M. I CANNOT HAVE THIS HAPPENING. THIS SEEMS TO BE A WIDESPREAD PROBLEM AMONG GM CARS FROM 2000-2009, AND I CANNOT FIND A TRUE REMEDY FOR IT. *TR
