2008 GMC ENVOY Complaints

TL* THE CONTACT OWNS A 2008 GMC ENVOY. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LAMP ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY STATED THAT THE SEAL THAT WAS ON TOP OF THE FIRE WALL WAS DAMAGED. AS A RESULT, THE WATER WAS SIPPING INTO THE ENGINE COMPARTMENT AND WAS GETTING ON THE COIL PACKS AND THE PLUGS. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 59,000. THE VIN WAS UNAVAILABLE.

GAS GAUGE UNKNOWINGLY DOESN'T WORK CORRECTLY, DRIVER RUNS OUT OF GAS, ALMOST GOT INTO MAJOR ACCIDENT. LUCKILY CAR BEHIND ME DIDN'T SLAM INTO ME. BUT IT ALMOST CAUSED A CHAIN REACTION OF REAR-ENDINGS. FAILURE IS DEFECTIVE GAS GAUGE/PUMP. INCORRECT INFO GIVEN TO DASH BOARD TELLING DRIVER IS AT 1/4 TANK OF GAS BUT THE REALTY IS THAT THE SENDING UNIT IS GIVING BAD INFO AND THE TANK IS POSSIBLY ON EMPTY. NO LIGHT COMES ON. DOING AN INTERNET SEARCH REVEALS GM'S PART IS KNOWN TO FAIL FREQUENTLY AND IS POORLY DESIGNED. *TR

SPEEDOMETER HAS WEIRD SOUNDS LIKE BIRDS FLAPPING WINGS. THE SPEEDOMETER HAS BEEN REPLACED THREE TIMES. GM USA CLAIMS THAT IT IS A DEFECT THAT THEY CANNOT REPAIR. THE ENVOY IS STILL UNDER WARRANTY. REALLY ISN'T ACCEPTABLE. MAKES ONE WONDER IF THE READINGS ON MILEAGE, AND SPEED ARE ACCURATE. *TR

2008 GMC ENVOY 51,000 MILES EXHAUST MANIFOLD CRACKED I HAD IT REPLACED AND WAS TOLD BY DEALER A 3 DAY WAIT WOULD BE NECESSARY AS THEY HAD USED STOCK PARTS ON ANOTHER ENVOY WITH SAME PROBLEM . ADVISED ME NOT TO DRIVE BECAUSE IT MAY CATCH FIRE. *TR

BOUGHT THE VEHICLE LAST NOVEMBER FROM GEORGIAN PONTIAC BUICK GMC IN BARRIE ONTARIO CANADA LAST NOVEMBER 2009. LEARNED I HAD A CRACKED EXHAUST MANIFOLD ON MY 2008 ENVOY AT 87 000 KM. IT HAS NOT YET BEEN REPAIRED. RESEARCH IS ONGOING. *TR

WHILE ON OUR WAY BACK TO OUR MOTOR HOME THE BRAKE PEDAL ON MY 2008 GMC ENVOY WENT TO THE FLOOR WHEN I TRIED TO STOP IN HEAVY TRAFFIC ON HWY 503 IN THE STATE OF WASHINGTON. AFTER PUMPING THE BRAKE QUICKLY I WAS ABLE TO REGAIN SOME BRAKING POWER. WHEN I CALLED THE LOCAL GMC DEALER (CARR GMC) IN VANCOUVER THE SERVICE ADVISER CONFIRMED THAT IT WAS THE MASTER CYLINDER. NOW THIS HAPPENED ON TUESDAY JULY 20, 2010, THE SERVICE ADVISER GAVE ME AN APPOINTMENT FOR THURSDAY JULY 22 BETWEEN 9:00 TO 9:30 AM. I ARRIVED AT 9:10 AM AND WAS TOLD THAT IT WOULD TAKE 2-1/2 TO 3 HOURS TO DIAGNOSE THE PROBLEM. NOW THIS WAS THE SAME PERSON THAT TOLD ME ON THE PHONE TWO DAY PRIOR THAT I HAD A BAD MASTER CYLINDER. NOW I JUST DROVE THIS CAR 48 MILES WITH THE BRAKES NOT WORKING PROPERLY. THE DEALER DID NOT HAVE A MASTER CYLINDER IN STOCK AND WAS HAVING ONE OVERNIGHTED IN FROM LANCING, MI AND WOULD CALL ME WHEN IT WAS REPAIRED. NOW I DON'T KNOW OF HOW MANY OTHER VEHICLES THIS HAS HAPPENED TOO, BUT HAVING A MASTER CYLINDER FAIL ON A CAR THAT HAS ONLY 31,000 MILES ON IT IS NOT GOOD AND A REAL SAFETY ISSUE. *TR

THE BRAKES ON OUR GMC ENVOY "SKIP" WHEN THERE IS WET WEATHER, BUMPY ROADS AND ESPECIALLY SNOW. WHEN TRYING TO BRAKE, THE BRAKES DON'T SEEM TO GRAB AND IT TAKES EXTRA LONG TO STOP. WE HAVEN'T HAD ANY CRASHES, BUT SEVERAL CLOSE CALLS DUE TO THE BRAKES NOT ENGAGING. IN DRY AND NORMAL WEATHER, THEY WORK FINE. *TR

HELLO: 2008 ENVOY. DOORS LOCK AUTOMATICALLY. WHETHER OR NOT I WANT THEM TO LOCK AUTOMATICALLY THEY DO AND THUS, DO NOT OPEN WITH THE INSIDE HANDLE. (NOT SPEAKING OF THE 'CHILD LOCK FEATURE' ON THE REAR DOORS.) THE SYSTEM IS NOT SET UP PROPERLY IN MY OPINION. REGARDLESS ON HOW IT WORKS TO MAKE ALL THE DOORS LOCK, THE DOORS SHOULD OPEN FROM THE INSIDE WITH THE INSIDE DOOR OPEN LEVER EITHER FOR AN EMERGENCY OR FOR CONVENIENCE. PLEASE KNOW THIS CONCERN IS SEPARATE AND ASIDE FROM THE "CHILD LOCK FEATURE" FOR THE REAR DOORS. PLEASE CONSIDER TO RETHINK THIS AND SUGGEST THAT THE MANUFACTURER GIVE THE OPERATOR THE CHOICE WHETHER OR NOT TO BE FORCED LOCKED IN ESPECIALLY BECAUSE SOME OF US MAY NOT REMEMBER TO HIT SWITCH A OR LEVER B FIRST TO GET OUT IN A HURRY. I HAVE SPOKEN WITH ONSTAR AS WELL AS WITH SERVICE PEOPLE AT THE DEALERS TO NO AVAIL. ALSO, MAY I ASK, DO THE UNLOCK SWITCHES WORK DURING A BATTERY FAILURE? THANK YOU FOR THE OPPORTUNITY TO PREVENT A POTENTIAL PROBLEM. *TR

I HAVING PROBLEMS WITH MY STABILITRAK SYSTEM THE ENGINE LIGHTS COMES ON AND I JUST HAD THE THERMOSTAT SENSORS CHANGE WHICH TOOK THEM THREE TIME TO FIND THE PROBLEM AND MY DRIVERS WINDOW SENSORS WAS REPLACED AND THERE A SUDDEN THUMB WHEN YOU BRAKE AS THOUGHT YOU HAVE BEEN HIT FROM BEHIND. *TR

I PURCHASED A 2008 ENVOY DENALI 7/08 DURING THE MIDDLE OF NOVEMBER WHILE DRIVE THE TEMP GAGE DROP TO THE LOWEST POINT AND STARTED CUTTING OFF HESITATING TO START. I THEN CONTACT ON-STAR THEY STATED IT WAS THE COOLING SYSTEM AND SHOULD BE TAKEN TO THE DEALER ON 10/19/09 I WENT AND WAS TOLD IT WAS THE TEMP SENOR WHICH WAS REPLACE THAT TUESDAY. THURSDAY THE SAME ISSUE ACCORD AGAIN I NOTIFIED ON-STAR THEY STATED THIS TIME IT WAS THE TRANSMISSION FRIDAY I WENT TO THE DEAL TO BE TOLD THEY COULD NOT WORK ON THE CAR UNTIL MONDAY. AS I WS SPEAKING TO A TECH THEY STATED IT SOUNDS LIKE THE TRANS AND THE MGR APPROACHED AND STATED I AM HANDLING THIS AND DIRECTED ME TOWARD THE DESK AND STATED HE HAD A RENTAL FOR ME AND ARRANGED A RIDE FOR ME. I TRULY BELIEVE THERE IS SOMETHING WRONG WITH THIS CAR AND TO MAKE THIS WORSE MY NAVIGATION SYSTEM HAS FAILED ME TWICE AS WELL. *TR
