2006 GMC Envoy Denali

WHEN STARTING MY VEHICLE AND START TO DRIVE I NOTICE 2 CHECK ENGINE LIGHTS POP ON. ONE ENGINE LIGHT HAS A ARROW POINTING DOWN AND THE OTHER JUST HAVE THE ENGINE LIGHT SYMBOL AND THE MY SPEED STARTS TO REDUCE A LOT. I WILL PULL OVER TO THE SIDE OF THE ROAD SHUT THE CAR OFF WAIT FOR 5-10 MINUTES AND CRANK IT UP AND AFTER MAYBE 15-20 MINUTES OF DRIVING IT POPS BACK ON. I'VE HAD THE MECHANIC TO DIAGNOSTIC MACHINE AND HE HAS SAID THE THROTTLE BODY NEEDS CHANGING, HAD THAT DONE AND THE SAME PROBLEM CAME BACK. SO I HAD MY OLD ONE PUT BACK ON AND THEN THE MECHANIC SAY MAYBE IT'S THE GAS PEDAL SENSOR. HAD THAT CHANGED AND THE PROBLEM IS STILL THEIR. I LOVE MY TRUCK BUT I DON'T HAVE THE MONEY TO KEP TRYING TO FIX THIS PROBLEM. I NEED HELP, FROM SOMEONE, PLEASE

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.

I HAVE HAD 4 BATTERY AND LIGHTS FLASH AND HARD DRAW ON ALT HAVE REPLACED ALT WITH NEW DELCO NEW LIGHTS STILL FLASH DRAWS LIGHTS DOWN. BEEN TO DEALER DEALER FROM2008 TO NOW AND THEY TELL ME I DON'T DRIVE VERY NEED TO DRIVE MORE CARE HAS 40"000 MILES THEY CAN'T FIND ANYTHING WRONG. YOU CAN DRIVE OR BE SETTING RUNNING STILL DOES THIS IT PULL DOWN ON ENGINE PULLS ALT GOES TO12 VOLTS THEN GOES ON

TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 14V755000 (VISIBILITY) HOWEVER, THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE CONTACT HAD NOT EXPERIENCED A FAILURE. THE VIN WAS NOT AVAILABLE. UPDATED 03/09/16*LJ *CN

FIRST OFF MY ELECTRICAL PANEL IN MY STEERING WHEEL NONE OF THE LIGHTS ARE ON AND WITH MY WINDSHIELD WIPERS SOME TIME THEY WILL COME AND WHEN IT START TO RAIN AND THEY WILL STOP WORKING THIS IS VERY DANGEROUS BECAUSE I NEVER KNOW WHEN THEY GOING TO WORK OR NOT DRIVING LIKE THIS CAN BE A DEATH TRAP, THIS BEEN GOING FOR ABOUT 6 MONTHS I TOLD THEM AFTER THE RECALL FOR MY DOOR PANEL THEY SAID IT MIGHT BE RECALL FOR THIS AS WELL NOTHING YET.

2 PROBLEMS WITH MY 06 ENVOY DENALI. MY BATTERY DIED AND AFTER JUMPING THE VEHICLE, ALL FRONT VENTS WILL NO LONGER BLOW AIR FROM THEM. ONLY TOP AND FLOOR WORK!. ALSO MYSTERIOUSLY DISAPPEARING OIL. APPARENTLY FAULTY PVC VALVE COVER NOW CAUSED ENGINES DAMAGED. NEEDS REPLACING AT $6700!!! THIS SHOULD HAVE BEEN A RECALL! NOW I'M STUCK WITH A VEHICLE I CANT DRIVE OR FIX AND STILL OWE 11,900 ON IT. OWNED IT 9MOS! WARRANTY DOESN'T WANT TO COVER THIS ISSUE

TOOK VEHICLE IN FOR BATTERY CHANGE, AFTER RECEIVING VEHICLE BACK, NOTICED THAT DASH VENTS WOULD NOT OPERATE, DEFROSTERS AND FLOOR VENTS STILL WORK, CONTACTED GM- THEY ACKNOWLEDGED THERE MIGHT BE A PROBLEM WITH BLEND DOOR ACTUATOR, BUT NEEDED TO SEE VEHICLE FOR REPAIRS, ESTIMATED COST- $1000.00. DID ONLINE CHECKING, THIS IS A RECURRING PROBLEM WITH GM DAMPER MOTORS FAILING, OFTEN AFTER BATTERY CHANGE. ONLY SOLUTION IS CHANGE DAMPER MOTOR.

WHILE ATTEMPTING A FULL STOP AFTER PULLING INTO PARKING LOT, VEHICLE WOULD NOT STOP, ABS CAME ON AND PREVENTED ENVOY FROM REACHING FULL STOP. HAD TO PUT VEHICLE IN NEUTRAL AND USE E-BRAKE. OCCURRED 4 MORE TIMES BEFORE I COULD TAKE FOR SERVICE. MECHANIC DIAGNOSED ISSUE WITH ABS SENSORS, ALTHOUGH SENSORS DID NOT REPORT AS FAULTY. ONLINE RESEARCH INDICATES THIS WAS A COMMON GM FAILURE FROM 02-08 IN TRUCKS IN AREAS WHERE SALT/SNOW IS PREVALENT. REMEDY WAS DISABLE TRACTION CONTROL AND ABS, CANT AFFORD TO REPLACE FRONT BEARINGS AND REAR SENSORS. PROBLEM ONLY OCCURS INTERMITTENTLY, AND ONLY WHEN ATTEMPTING STOP FROM LOW INITIAL SPEEDS.
