HI I HAVE AN 07 ENVOY DENALI AND I HAVE A PROBLEM WITH MY ENGINE LIGHT BEING ON. TOOK IT TO GET A DIAGNOSTIC CHECK AND THE THROTTLE POSITION SENSOR NEEDS TO BE REPLACED. I HAVE REPLACED MY ALTENATOR AND BATTERY IN 2010. NOW MY BAGS THAT LIFTS THE TRUCK STRUGGLE AND DOES NOT WORK ON A DAILY BASIS, MY LIGHTS MAY NOT COME ON AND THE OIL GAUGE LIGHT IS ON (AND ALSO DROPPED DOWN TO ZERO) AND SERVICE STABILITRAK LIGHT STAYS ON. TWO YEARS AGO I REPLACE THE MOTOR THAT CONTROLS THE WINDOW THAT COST ME AROUND $500 BUCKS. I LIVE IN DC AND I CANNOT PASS INSPECTION BECAUSE OF THE ENGINE LIGHT IS ON. ON EDMUNDS.COM THERE ARE MANY TSB ISSUED FOR MY VEHICLE PURCHASED IN THAT YEAR. *KB

ENGINE STALLED WHILE DRIVING DOWN AN INCLINE WITHOUT ANY INDICATION UNTIL APPLYING THE BRAKES TO FIND THE POWER BRAKES HAD BEEN LOST. WEATHER CONDITIONS WERE SLICK AND THE VEHICLE STARTED TO SPIN AND COULD NOT BE CORRECTED DUE TO LOSS OF POWER STEERING. VEHICLE COULD NOT BE SLOWED USING THE LOWER ENGINE GEARS. ONCE THE VEHICLE COASTED TO A STOP, THE BATTERY LIGHT CAME ON. THE VEHICLE WAS PUT IN PARK, TURNED THE KEY TO THE ENGINE-OFF POSITION AND THEN ON. ONSTAR DIAGNOSTICS DID NOT DETECT ANY PROBLEMS IN SYSTEM TESTS. FUEL LEVEL WAS APPROX. 3 GALLONS. ***************************************************************************************************THE FAILURE ALMOST CAUSED AN ACCIDENT OF RUNNING OVER A PEDESTRIAN AND COLLISION WITH OTHER VEHICLES (NO CONTROL AND NO WARNING FROM THE VEHICLE SYSTEMS OF STALL). THIS IS THE SECOND INCIDENT; INITIAL INCIDENT OCCURRED WHILE LEAVING INCLINED DRIVEWAY - POTENTIAL OF ENTERING ROADWAY. MY CHILD WAS RIDING AS A PASSENGER IN THE VEHICLE FOR BOTH INCIDENTS. *************************************************************************************************** *TR
