One problem related to speedometer/odometer failure has been reported for the 2005 GMC Envoy. The most recently reported issues are listed below.
The speedometer fails to represent true vehicle speed. Using a gps we can monitor the inaccuracy in the gauge reading. The speedometer reflects a speed of 25 when actual speed is 45. This becomes worse as the vehicle is driven as the speedometer completely fails to register speed. An identical issue was pr3esent on a 2003 cheverolet truck we own which was repaired by gm under an in-house program resulting from a lawsuit. Gm has declined to repair this same problem on this model. If a driver cannot accurately determine his/her spped at any given moment the possiblility for safety related instances are increased for the driver and others.
