NHTSA Complaint #10456806 — 2004 CHEVROLET SSR

I BOUGHT A 2004 CHEVROLET SSR IN FEB.11, 2010 WAS A USED VEHICLE NO WARRANTY. TEST DRIVE WAS OK EVERYTHING WORKED AS EXPECTED. I STARTED NOTICING THAT I WAS GOING SLOWER THAN MOST CARS AROUND ME. I CHECKED WITH A FRIEND WHO DROVE BESIDE ME. IT WAS DETERMINED THAT THE SPEEDOMETER WAS OFF 10 TO 15 MPH. I CONTACTED CHEVROLET DEALER ABOUT PROBLEM IN MARCH 2010. I NEEDED TO DROP OFF MY TRUCK FOR A DIAGNOSTIC TESTING. IT WOULD TAKE 24 HOURS & OR 5 TO 7 DAYS AT $150 PER HOUR TO DETERMINE PROBLEM. THE PARTS & REPAIR LABOR TO FIX. I SAID THAT WAS OUTRAGEOUS. PLUS NO TECHNICIANS IN AREA WERE TRAINED ON THE SSR'S ELECTRONICS. I CONTACTED GM FOR HELP. SERVICE REQUEST #71-982295330 THE PROBLEM I WAS EXPERIENCING WAS NOT INCLUDED IN RECALL. NO 2003 THROUGH 2006 SSR'S WERE REPORTED TO BE HAVING ANY PROBLEMS WITH THE INSTRUMENT CLUSTER. THE DEALER FOUND NO PROBLEM & WAS NOT REPAIRED. I HAVE BEEN PUTTING UP WITH THE PROBLEM USING TACHOMETER AS A GUIDE TO SPEED. THE FIRST TIME I START TRUCK IT SEEMS TO BE JUST A FEW MILES PER HOUR OFF. BUT AS I GO THROUGH START CYCLES IT GETS TO BE MORE MPH OFF. IF VEHICLE SITS OVER NIGHT. 12 OR MORE HOURS. IT SEEMS TO RESET ITSELF. I WAS OUT TODAY 4/29/2012 FOR A DRIVE. I WAS PULLED OVER BY A POLICE OFFICER ON RADAR GOING 67 MPH IN A 55 MPH ZONE. I CHECKED MY SPEED AT THE TIME & WAS GOING 55 MPH. THE OFFICER LET ME OFF WITH A WARNING TO PARK VEHICLE TILL IT IS REPAIRED. NOW WHAT DO I DO? CHEVROLET DOES NOT HAVE A RECALL ON THIS VEHICLE & MANY PEOPLE THAT I KNOW ARE SSR OWNERS HAVE HAD THE SAME PROBLEMS WITH INSTRUMENT PANEL GAUGES. IT IS A KNOWN PROBLEM WITH SSR OWNERS. BUT AS I WAS TOLD. MOST HAD IT REPAIRED AT THERE OWN EXPENSE. NOW I HAVE A TRUCK WITH A INACCURATE SPEEDOMETER & NO PLACE TO GET REPAIRS DONE BY EXPERIENCED MECHANICS. I NEED MY SPEEDOMETER FIXED AT GM CHEVROLET EXPENSE. *TR
