Chevrolet Speedometer Failure Service Bulletin 07187I found this service bulletin related to the Chevrolet, GM speedometer failures that are prompting Chevrolet owners to demand a recall of the defective speedometers. If you have a GM or Chevrolet vehicle with a defective speedometer you may want to bring this service bulletin to your dealers attention. This service bulletin below references 2003 and 2004 model years but my 2005 has the same problem with the speedometer reading 120mph when i'm going anything over 40 mph. As I write this my truck is in the driveway turned off yet the speedometer says 55mph.

CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE DEALERSHIP TO ARRANGE AN APPOINTMENT IF THEY BELIEVE THEIR VEHICLE HAS THIS CONDITION. THE CUSTOMER IS BEING ASKED TO PROVIDE THE VIN SO THE IPC CAN BE ORDERED IN ADVANCE OF THE SCHEDULED APPOINTMENT. THIS WILL ELIMINATE THE NEED TO KEEP THE VEHICLE OVERNIGHT.

This may cause inaccurate readings, including the speedometer and fuel gauge.
