2006 GMC ENVOY DENALI Electrical System Problems

TL* THE CONTACT OWNS A 2006 GMC ENVOY DENALI. THE CONTACT STATED THAT THE VEHICLE FAILED TO START AND ALL THE WARNING INDICATORS ILLUMINATED. THE CONTACT MENTIONED THAT WHEN THE VEHICLE WOULD START, IT WOULD CUT OFF IMMEDIATELY. THE VEHICLE WAS TAKEN TO BETTEN BAKER CHEVROLET BUICK GMC (14120 NORTHLAND DR, BIG RAPIDS, MI 49307 (231) 629-4340) WHERE IT WAS DIAGNOSED THAT AN ELECTRICAL FAILURE WAS FOUND, BUT THE DEALER DID NOT KNOW THE EXACT CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA. THE FAILURE MILEAGE WAS APPROXIMATELY 126,000.

Mileage: 126,000

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

Mileage: 20,000

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.

ENGINE SUDDENLY STOPPED RUNNING, PLACED SHIFT LEVER TO PARK POSITION. ENGINE WOULD NOT RESTART. TRANSMISSION WAS NOW LOCKED IN PARK, CAUSING INABILITY TO PUSH VEHICLE TO SAFETY. REPAIR BY GMC DEALER INVOLVED REPAIRING ELECTRICAL SHORT IN FACTORY WIRING UNDER DASHBOARD AT THE FIREWALL, IN THE AREA OF THE BRAKE BOOSTER MOUNT. APPARENT CAUSE IS IMPROPER ROUTING OF WIRING AT TIME OF VEHICLE MFR, CAUSING ABRASION OF WIRING OVER TIME. *TR

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

Mileage: 45,435

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. DIAGNOSTICS DETERMINED THE IGNITION SWITCH WAS BAD AND SHOULD BE REPLACED. I HAD THE IGNITION SWITCH REPLACED 14 MONTHS AND 6070 MILES PRIOR TO THIS INCIDENT. THEY REPLACED THE IGNITION SWITCH. 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. OBVIOUSLY MY VEHICLE HAS THE SAME PROBLEM AS THE RECALLED VEHICLES, WHY IS IT NOT PART OF THE RECALL? 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 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

DRIVING AT 20 MILES AN HOUR AND HEAR A CRACKLING NOISE IN DRIVER DOOR PANEL. WINDOW ROLLED UP ON IT'S OWN, SIDE MIRRORS BEGAN TO READJUST THEMSELVES AND HEATED SEAT CAME ON. WHEN NOISE QUIT I HAD LOST ALL CONTROL OF PANEL CONTROLS. CALLED GM DEALER TO GET IT IN FOR THE RECALL ON MASTER SWITCH AND WAS TOLD THERE WERE NO PARTS OR REMEDY FROM GM AS OF YET. RECALL CAME OUT A COUPLE MONTHS AGO. CALLED ANOTHER DEALER AND TOLD THE SAME THING. I CALLED DIRECT TO GM AND WAS TOLD THERE WAS NO SOLUTION AT THIS TIME. I HAD NO WINDOW CONTROL, CAR WILL NOT LOCK, SIDE MIRRORS POINTED DOWN TO GROUND SO I CAN'T USE THEM. I CALLED BACK AND ASKED WHY A RECALL WAS ISSUED WHEN THERE WERE NO REPLACEMENT PARTS ON A SAFETY ISSUE SUCH AS THIS. KIDS CAN OPEN DOORS, CAN'T CHANGE LANES ON HIGHWAY DO TO MIRRORS AND CAN'T USE WINDOWS. AS I CONTINUED TO DRIVE THE CRACKLING CAME BACK AND SEAT REHEATED, MIRRORS REPOSITIONED, AND WINDOW TRIES TO GO DOWN. I CALLED AGAIN AND WAS TOLD I COULD SET AN APPOINTMENT AND WOULD HAVE TO PAY UP FRONT AND THEN GET REIMBURSED FROM GM. I TOLD THEM I WOULD NOT UNDER ANY CIRCUMSTANCES. THEY WOULD REVIEW AND GET BACK WITH ME IN 24-48 HOURS. NOTHING SO FAR.THIS MORNING WHILE DRIVING IN THE DARK THE NOISE STARTED AGAIN AND I LOST MY HEADLIGHTS, BLACK, NOTHING. SITTING AT A STOP SIGN TODAY, CAR RUNNING AND IN DRIVE, I LOST ALL DASH PANEL GAUGES FOR ABOUT 30 SECONDS. CAR STILL RAN AND EVERYTHING CAME BACK. FEARFUL OF A WRECK AND HAVING KIDS IN THE CAR WITH NO SAFETY LOCKS. I CAN'T MANUALLY LOCK HATCH SO I AM AT RISK OF AN EASY BREAK IN AND I AM IN THE MEDICAL FIELD AND TRAVEL WITH SUPPLIES THAT MUST BE LOCKED UP. NEVER BY ANOTHER GMC SOMETHING NEEDS TO BE DONE!!!! *TR

I WAS DRIVING 10 MPH AND THE SUV STALLED PUT IT IN PARK TO RESTART AND IT WOULD NOT START HAD IT TOWED TO A EX GM DEALER AND THEY REPLACED THE SWITCH . *TR

AFTER EXITING THE INTERSTATE WITH SPEEDS UP TO 65MPH AND BEFORE I COULD SLOW DOWN TO THE TO THE CURRENT SPEED LIMIT OF 25MPH THE ENGINE OF MY GMC ENVOY DENALI 2006 ABRUPTLY CUT OFF. I STEERED TO THE CURB TO GET OUT OF THE ROAD OF TRAFFIC WITH THE FIRST THOUGHT THAT I WAS OUT OF GAS; BUT I HAD A FOURTH OF A TANK. THE GMC DEALERSHIP FIRST TOLD ME THE IGNITION SWITCH BURNT OUT AND MY REPAIR BILL WAS $277. SEVERAL DAYS LATER THEY CALLED ME AND SAID THE VEHICLE STALLED AGAIN WHILE THEY WERE TEST DRIVING IT. NOW THEY SAY THE IGNITION SWITCH BURNT OUT A MODULE WHICH WOULD COST ANOTHER $700. TOTAL BILL WITH LABOR AND TAX....$1059.57. *TR

GM IGNITION SWITCH PROBLEM WITH SUVS!!!!!!! WAS DRIVING ABOUT 45 MPH WITH OUR GRANDKIDS AND ALL POWER WAS LOST. NO POWER STEERING, NO BRAKES. RADIO AND ELECTRIC WINDOWS STILL WORKED AFTER STOPPING (LUCKILY SAFELY). SERVICE REPAIR REPORTED THAT IGNITION SWITCH CIRCUIT THAT CONTROLS THE ENGINE SHORTED OUT TURNING OFF ENGINE AT 45 MPH. THIS IS THE 5TH IGNITION SWITCH ON THIS VEHICLE. GM HAS A LARGER IGNITION SWITCH PROBLEM THAN THEY ARE ACKNOWLEDGING. LUCKILY WE JUST GOT OFF THE HIGHWAY GOING 70 MPH OR WE WOULD HAVE CRASHED. PLEASE RESEARCH THIS CLASS OF VEHICLE (SUVS/TRUCKS) AS I BELIEVE GM HAS A SIMILAR PROBLEM AS THE COBALTS!!!!!!! *TR

I'VE HAD CAR ONE MONTH TO THE DAY WERE DO I START .THE CAR CUTS OUT WHILE DRIVING. SHOWS CODES ONE SEC. NEXT SEC I HAVE SEVERAL LOOKS CLEAN BUT SO MANY PROBS I REALLY FEEL [XXX]. I PURCHASED A LEMON INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

PURCHASED THIS VEHICLE IN OCTOBER OF 2013 AND NOW THE DRIVERS DOOR ELECTRICAL SYSTEMS WORKS INTERMITTENTLY. I CONTACTED GMC BECAUSE THIS WAS A RECALL IN JUNE OF 2013. GMC TOLD ME THE WORK WAS ALREADY DONE SO TO HAVE THIS PROBLEM FIXED I WOULD HAVE TO PAY FOR IT OUT OF POCKET. THE PROBLEM I HAVE IS THEY DIDN'T FIX THE PROBLEM THEY ONLY MASKED IT WITH A CHEAP PIECE OF PLASTIC. IF A VEHICLE HAS A RECALL AND IT IS NOT FIXED CORRECTLY DOES THE COMPANY LEGALLY HAVE TO PLAY TO FIX THE PART AGAIN BECAUSE ONE OF THEIR DEALERSHIPS WAS NEGLIGENT IN FIXING THE RECALL CORRECTLY? *JS

GM HAS A RECALL OUT FOR ENVOY DENALI DRIVER DOOR PANELS SHORTING OUT CAUSING SMOKE AND POSSIBLE FIRE. THIS IS A FACT. MY DOOR DID START ON FIRE AND THANK GOD I WAS STILL IN THE STORE WHEN IT HAPPENED. BROUGHT THE TRUCK TO THE DEALER, DEALER SAYS "YES" THIS IS A RECALL ISSUE, GM HAS THE DEALER HOLD MY TRUCK FOR THREE WEEKS WHILE THEY DECIDE IF THEY ARE GOING TO PAY FOR THE REPAIRS TO THE RECALL THAT DID START ON FIRE. AFTER THREE WEEKS THE THIRD PARTY REPRESENTING GM CALLS AND SAYS "NO" GM IS REFUSING TO PAY FOR THE FIRE DAMAGE. ???? HOW DO YOU HAVE A RECALL BUT NOT COVER THE DAMAGE IF IT ENDS UP HAPPENING. SEPTEMBER 2013 ISSUE OF CONSUMER REPORTS PAGE 16 HAS THE RECALL ARTICLE. *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. THERE WERE TIMES WHERE THE AIR WOULD JUST START BLOWING AND NO BUTTONS WERE PUSHED. ALSO, THE DEFROSTER STOPPED WORKING. THE CONSUMER CONTINUED TO EXPERIENCE PROBLEMS WITH THE VEHICLE NOT COMING OUT OF PARK. *JB

FUEL GAUGE IS NOT WORKING PROPERLY ON MY VEHICLE. IT STAYS ON "E" WHEN THERE IS PLENTY OF GASOLINE IN THE CAR. THERE HAVE BEEN SEVERAL COMPLAINTS ABOUT THIS THAT I HAVE SEEN ON WEBSITES. OCCASIONALLY THE GAUGE WILL MOVE UP BUT THEN GO BACK TO "E". I WENT TO DEALER AND THEY SAID IT IS A BAD FUEL SENOR GAUGE WHICH IS IN THE GASOLINE TANK. SEEMS LIKE THIS IS A COMMON ISSUE AND COULD CAUSE OTHER PROBLEMS. THE FUEL GAUGE HAS BEEN LIKE THAT FOR OVER 6 MONTHS, AS THE COST WAS ASTRONOMICAL AND I BELIEVE THERE SHOULD BE A RECALL. ADDITIONALLY, RECENTLY MY OIL PRESSURE GAUGE HAS SHOWN THE MAX AMOUNT AND THEN LAST NIGHT IT WENT DOWN TO THE LOWEST AMOUNT ON THE INSTRUMENT PANEL. IT GOES BACK AND FORTH FROM HIGH TO LOW AND THE OIL PRESSURE LOW LIGHT COMES ON THE INSTRUMENT PANEL AND THEN GOES OFF. IT SAYS TO STOP ENGINE. THERE DOES NOT APPEAR TO BE ANYTHING PHYSICALLY WRONG WITH MY ENGINE AND I WILL BE TAKING IT TO THE DEALER TOMORROW TO CONFIRM THAT. I BELIEVE BOTH OF THESE ISSUES ARE CAUSED BY A FAULTY INSTRUMENT PANEL OR ELECTRICAL SYSTEM INCLUDED IN GM'S MODELS. I HAVE A FAMILY MEMBER WITH AN OLDER GMC SUV WITH SIMILAR ISSUES AND THEY ALSO HAD ISSUES WITH A GMC TRUCK THEY USED TO HAVE BUT GOT RID OF IT, DUE TO THE MALFUNCTIONS. SEEMS LIKE A VERY COMMON ISSUE THAT SHOULD BE RESOLVED BY GE. *TR
