NHTSA Complaint #10668755 — 2004 BUICK RENDEZVOUS

THE SPEEDOMETER STOPS WORKING CORRECTLY. WHILE TRAVELING AT HIGHWAY SPEEDS THE SPEEDOMETER WILL READ ANYWHERE BETWEEN BELOW 0 MPH AND 30 MPH. IT HAPPENS REGARDLESS OF THE WEATHER. THERE HAVE BEEN MULTIPLE OCCURRENCES THAT THE SPEEDOMETER IS WORKING CORRECTLY, (CONFIRMED BY CALCULATIONS USING TIME, MILE MARKERS & ODOMETER READINGS,) AND AT ANY POINT DURING TRAVEL IT WILL STOP AND THE NEEDLE IS OBSERVED TO GRADUALLY DROP BELOW THE 0 MPH MARK. SOMETIMES RESTARTING, WHETHER BY TURNING OFF THE IGNITION OR USING THE AUTOSTART TO REMOVE THE KEY WHILE LEAVING THE VEHICLE RUNNING, WILL TEMPORARILY CORRECT THE PROBLEM. THE PROBLEM WAS NOTED BY AN INDEPENDENT MECHANIC AT THE END OF SEPTEMBER WHILE ADDRESSING POTENTIAL TRANSMISSION ISSUES. (WHICH ALSO HAS NOT BEEN RESOLVED. THE MECHANIC WAS UNABLE TO FIND A CAUSE TO "HARD SHIFT" PROBLEM THAT BEGAN SEVERAL MONTHS AGO.) THE CURRENTLY MILEAGE ON THE VEHICLE IS APPROXIMATELY 81,200 MILES. IT IS BEING TAKEN TO A MECHANIC THIS WEEK TO ADDRESS THE ISSUE. *TR
