FAILURE OF THE DOD LIFTER, ALSO KNOWN AS THE ACTIVE FUEL MANAGEMENT SYSTEM. WHILE AT SPEED ON THE FREEWAY, THE DOD LIFTER ON CYLINDER #7 FAILED CAUSING A MISFIRE ON THE CYLINDER WHICH CAUSED TEH ENGINE TO SHAKE VIOLENTLY. THIS IS THE 2ND FAILURE OF A DOD LIFTER ON MY TRUCK. IN NOV 2014, A DOD LIFTER ON CYLINDER #6 FAILED, CAUSING A ENGINE MISFIRE AND A VIOLENT SHAKE. THE CAUSE OF THE FAILURE WAS DETERMINED TO BE LACK OF OIL PRESSURIZE THE DOD LIFTER. UPON DECIDING TO REBUILD THE MOTOR RATHER THAN REPLACING THE MOTOR, WE DECIDED TO REPLACE ALL INTERNAL COMPONENTS OF THE MOTOR SIMPLY BECAUSE THE MOTOR WOULD NEED A FULL TEAR DOWN ANYWAY. THE LIFTERS, OIL PRESSURE SOLENOIDS OF THE DOD LIFTERS, ROCKERS, ROCKER ARMS, SPRINGS AND CAMSHAFT WERE ALL REPLACED THINKING THAT WE MIGHT AS WELL REBUILD THE BLOCK WITH NEW COMPONENTS TO SAVE OFF ANY FUTURE ISSUES. AFTER 1 MONTH IN THE GMC SERVICE CENTER, THE VEHICLE WAS BACK ON THE ROAD IN DEC 2014. THIS REPAIR WAS $5,900.00 IN MARCH 2016, YES 14 MONTHS LATER, A 2ND FAILURE OF A DOD LIFTER OCCURRED ON CYLINDER #7. THE VEHICLE EXHIBITED THE SAME ISSUES AS IN NOV 2014. THIS FAILURE OCCURRED ON THE REBUILT MOTOR ON NEW COMPONENTS INSTALLED IN NOV 2014. THIS REPAIR WILL COST $2500 JUST TO REPLACE THE 1 LIFTER. NO OTHER COMPONENTS. THIS LEADS ME TO BELIEVE THAT A THE DOD FAILURE IS MORE COMMON AND IS A DESIGN FLAW OF THE ACTIVE FUEL MANAGEMENT SYSTEM. THIS ISSUE IS MORE THAN A TSB ISSUE, IT SHOULD BE A RECALL.

ENGINE STALLED A FEW SECONDS AFTER STARTING, THEN WOULD NOT CRANK, ONLY CLICKED. I HAD THE CAR TOWED IN FOR SERVICE. TECHNICIAN CHECKED BATTERY. IT WAS FULLY CHARGED AND VEHICLE HAD FULL VOLTAGE. DIAGNOSTICS DETERMINED LOW VOLTAGE OUT FROM THE IGNITION SWITCH. RECOMMENDED IGNITION SWITCH SHOULD BE REPLACED. I HAD THE IGNITION SWITCH REPLACED TWICE ALREADY. I HAVE HAD TO REPLACE THREE IGNITION SWITCHES IN THREE YEARS AT A TOTAL COST OF $817. I UNDERSTAND THAT GM HAS RECALLED IGNITION SWITCHES ON SEVERAL MODELS BUT THE ENVOY IS NOT PART OF THAT RECALL. OBVIOUSLY MY VEHICLE HAS THE SAME PROBLEM AS THE RECALLED VEHICLES, WHY IS IT NOT PART OF THE RECALL? THE FIRST IGNITION SWITCH FAILED AT 65-70 MPH ON THE FREEWAY. THIS IS A VERY DANGEROUS PROBLEM. SINCE THE REST OF THE ELECTRONICS ARE CONNECTED TO THE IGNITION I HAVE NO SAFETY EQUIPMENT SUCH AS AIR BAGS. IF I WOULD HAVE BEEN IN AN ACCIDENT, IT COULD HAVE BEEN FATAL. *TR

ENGINE WOULDN'T CRANK AT TIMES. STARTS NORMALLY WHEN IT DOES. AFTER ABOUT A WEEK OF HAVING THIS PROBLEM I TOOK A THE CAR IN FOR SERVICE.

THE PART WAS UNDER WARRANTY BUT DIAGNOSTICS AND LABOR WAS $220. THE FIRST IGNITION SWITCH FAILED AT 65-70 MPH ON THE FREEWAY. I UNDERSTAND THAT GM HAS RECALLED IGNITION SWITCHES ON SEVERAL MODELS BUT THE ENVOY IS NOT PART OF THAT RECALL.

I WAS DRIVING ON THE FREEWAY AT 65-70 MPH. THE ENGINE LUGGED A LITTLE LIKE IT WAS RUNNING OUT OF GAS BUT THE TANK WAS HALF FULL. THE ENGINE RESUMED RUNNING AT FULL SPEED. A FEW SECONDS LATER THE ENGINE SHUT OFF. I WAS ABLE TO COAST LONG ENOUGH TO PULL OFF THE FREEWAY. BUT WITHOUT POWER STEERING AND BRAKES THIS WAS NOT AN EASY TASK. ONCE THE CAR STOPPED I TURNED OFF THE IGNITION AND PUT THE CAR IN PARK. I TRIED TO RESTART THE CAR BUT NOTHING HAPPENED. I CALLED A TOW TRUCK BUT THE DRIVER COULD NOT GET THE CAR TO SHIFT INTO NEUTRAL IN ORDER TO PUT IT ON THE CAR CARRIER BECAUSE THE SHIFTER IS TIED TO THE ELECTRONICS. WITHOUT POWER IT DOES NOT WORK. HE HAD TO CALL FOR ANOTHER TOW TRUCK TO PULL THE VEHICLE IN FOR SERVICE. THE SERVICE TECHNICIAN TESTED AND FOUND LOW VOLTAGE FROM THE IGNITION SWITCH. HE REPLACED THE IGNITION SWITCH. DIAGNOSTICS, PART AND LABOR $307. THIS IS A VERY DANGEROUS PROBLEM. IF I WAS NOT ABLE TO MOVE OUT OF TRAFFIC I WOULD HAVE BEEN A SITTING DUCK IN THE MIDDLE IF THE FREEWAY. SINCE THE REST OF THE ELECTRONICS ARE CONNECTED TO THE IGNITION I HAD NO SAFETY EQUIPMENT SUCH AS AIR BAGS. IF I WOULD HAVE BEEN IN AN ACCIDENT AT FREEWAY SPEEDS, IT COULD HAVE BEEN FATAL. *TR

IN THE REAR COMPARTMENT OF MY 2006 GMC ENVOY DENALI THERE IS A COMPRESSOR. THERE MUST BE A LEAK BECAUSE MY CAR LOOKS LIKE A LOW RIDER IN THE MORNING UNTIL I START IT AND THE COMPRESSOR COMES ON AND IN ABOUT 3 OR 4 MINUTES IT IS BACK TO IT'S NORMAL DRIVABLE HEIGHT. HAS THERE BEEN THIS PROBLEM WITH ANYONE ELSE AND IS THERE A RECALL TO FIX THIS PROBLEM? *TR

2006 ENVOY DENALI. CONSUMER WRITES STATES GAS NEEDLE STOPPED FUNCTIONING *TGW THE CONSUMER STATED THE GAS NEEDLE BEGAN TO FLUCTUATE IN THE BEGINNING AND SINCE THAT TIME, THE NEEDLE HAS BEEN STUCK ON EMPTY, AND THE ENGINE LIGHT ILLUMINATED AS A RESULT. IN MARCH OF 2009, WHEN THE CONSUMER STARED THE VEHICLE, IT SOUNDED AS IF THERE WAS SOMETHING METAL TUMBLING AROUND UNDER THE HOOD. UPON INSPECTION OF THE VEHICLE, IT WAS DETERMINED THE ENGINE NEEDED TO BE REPLACED. ON JUNE 10, 2010, THE VEHICLE WOULD NOT START AND HAD TO BE TOWED TO THE DEALER. AN INSPECTION REVEALED A STARTER WAS NEEDED. ALSO, AN ALIGNMENT WAS DONE AND THE REAR BRAKE LIGHT WAS REPLACED. ON JUNE 12, 2010, THE VEHICLE WOULD NOT COME OUT OF PARK. AFTER 25 MINUTES AND OVER 50 ATTEMPTS, IT FINALLY CAME OUT OF PARK. THE CONSUMER DROVE TO THE DEALER, BUT THEY WERE UNABLE TO FIND A PROBLEM. SEPTEMBER 2010, THE CONSUMER NOTICED THE REAR OF THE TRUCK WAS SITTING VERY LOW. THE REAR END AIR SUSPENSION NEEDED TO BE REPLACED. THE AIR CONDITION RANDOMLY WORKED.
