NHTSA Complaint #10347169 — 2005 GMC ENVOY

SPORADIC FAILURE OF SPEEDOMETER - REGISTERS CORRECTLY ONE MOMENT, OR MAY READ 30 MPH OR 0 MPG WHEN KEEPING WITH THE FLOW OF TRAFFIC ON THE INTERSTATE. WHILE THIS DOES NOT OCCUR EACH TRIP, IT DOES OCCUR SEVERAL TIMES EACH WEEK. FUEL GAUGE MALFUNCTION - READS ONE-HALF TANK AT 179 MILES; 20 MILES LATER READS ONE-QUARTER TANK. ISSUES "FUEL LEVEL LOW" WARNING AFTER REFUELING AND FOR NEXT 3 TO 4 TIMES VEHICLE IS STARTED HEADLIGHTS DIM BRIEFLY WHEN ACCELERATOR IS RELEASED. FREQUENT NEED TO REPLACE EXTERIOR LAMPS THE PROBLEMS FIRST MANIFEST IN THE NEED TO REPEATEDLY CHANGE BRAKE AND TAILLIGHT BULBS, AND THE DIMMING OF THE HEADLIGHTS, WHICH CONTINUES. THEN, SPORADICALLY, THE SPEEDOMETER STOPPED FUNCTIONING, OR ONLY REGISTERED A FRACTION OF THE SPEED THE VEHICLE WAS TRAVELING. AFTER THAT, AT START UP, THE "FUEL LEVEL LOW" WARNING, WHICH ACTIVATES WHEN THE VEHICLE DETERMINES IT HAS FUEL TO TRAVEL 40 ADDITIONAL MILES, STARTED TO CHIME WHEN THERE WAS MORE THAN ONE-HALF TANK OF FUEL. THE WARNING ALSO NOW ISSUES WHENEVER THE VEHICLE IS REFUELED. THE POTENTIAL FAILURE OF THE EXTERIOR LIGHTING SYSTEM PRESENTS A CLEAR HAZARD TO THE OCCUPANTS OF THE VEHICLE AND OTHERS - THE DRIVER WOULDN'T BE ABLE TO SEE WHERE HE IS GOING, AND OTHER DRIVERS WOULDN'T BE ABLE TO SEE THE VEHICLE HEADING TOWARD THEM. THE FUEL SYSTEM ISSUES COULD LEAD TO UNEXPECTEDLY RUNNING OUT OF FUEL, CREATING THE POTENTIAL FOR A DISABLED VEHICLE OR ITS DRIVER BEING HIT BY ANOTHER. IN ADDITION, DEPENDING ON THE CAUSE OF THE MALFUNCTION, THE VEHICLE COULD BE SUSCEPTIBLE TO FIRE. WITHOUT A FUNCTIONING SPEEDOMETER, THE DRIVER CAN EASILY TRAVEL TOO FAST FOR CONDITIONS, OR ENDANGER HIMSELF AND OTHERS IN A CONSTRUCTION ZONE. CURRENTLY, UNTIL THE SPORADIC PROBLEMS BECOME REGULAR, THE GARAGE WILL NOT FIX THE VEHICLE. *TR
