2006 GMC Envoy Engine Problems

The contact owns a 2006 GMC Envoy. The contact stated that occasionally the vehicle was not able to be started. Additionally, while driving at various speeds, the steering wheel seized and the vehicle lost motive power. The vehicle was taken to an independent mechanic. The mechanic informed the contact that no codes appeared on the code reader and replaced the battery; however, the failure recurred. The vehicle was then taken to the dealer and diagnosed that the computer needed to be reset after the battery was replaced. The dealer reset the computer; however, the failure recurred. The vehicle was taken back to the dealer and diagnosed that there was a leak in the intake manifold after a smoke test was performed. The dealer replaced the manifold gasket; however, the failure recurred. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 142,000.

TRANSMISSION REPLACED TWO TIMES IN TWO YEARS

2006 GMC ENVOY DENALI. CONSUMER WRITES IN REGARDS TO DROPPED VALVE. *LD *JS

JUST LIKE ALL THE OTHERS MY 2006 GMC ENVOY DENALI HAS A BAD #7 LIFTER. WHERE ARE THE RECALLS????? GM IS GETTING AWAY WITH RIPPING OFF THE PUBLIC AND NO ONE CARES. JUST BAIL THEM OUT AND THEN LET THEM ROB ALL OF US ALSO???????????????

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.

MISFIRE P0301 A LOT OF 5.3 ENGINES IN 2006 GMC DENALI CAN FINE PROBLEM NOT WIRES CHECKED COILS CHECKED FUEL CHECKED COMPRESSION OK IT HAS COST ME MORE THAN 1100.00 DOLLARS STILL MISFIRE. *TR

TL* THE CONTACT OWNS A 2006 GMC ENVOY. WHEN STARTING THE VEHICLE, THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 104,000.

TL* THE CONTACT OWNS A 2006 GMC ENVOY. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 30 MPH, THE VEHICLE STALLED. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSIS. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 120,000.

IN THE MORNING THE CAR RUN FINE, BUT ONCE THE ENGINE IS WARM AND I START TO RUN ERRANDS IT STALLS. IF I WAIT ABOUT 10MIN OR SO... I MUST SPEED HOME OR TO A SAFE AREA TO LET THE ENGINE COOL. IF I COME BACK IN A FEW HOURS,THE TRUCK WILL START WITH NO PROBLEM. IT HAS BEEN TO THE SHOP MORE OFTEN THEN I REMEMBER. IS THERE ANYONE HAVING THESE SAME ISSUES? *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

TL* THE CONTACT OWNS A 2006 GMC ENVOY. THE CONTACT STATED THAT WHEN COMING TO A STOP, THE VEHICLE WOULD SHAKE VIOLENTLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THE CYLINDER HEAD VALVE SEATS WERE WEARING OUT PREMATURELY AND AS A RESULT, THE CYLINDER AND THE VALVE SEATS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 98,000 AND THE CURRENT MILEAGE WAS 138,000.

AFTER DRIVING APPROXIMATELY 20 MILES ON CRUISE CONTROL I TAPPED THE BRAKES TO DISENGAGE THE CRUISE CONTROL. THE VEHICLE DRAMATICALLY LOST POWER AND THE CHECK ENGINE LIGHT CAME ON. I WAS ABLE TO AVOID OTHER TRAFFIC AND PULL OVER ON THE FREEWAY, I THEN DROVE OFF THE FREEWAY ON THE SHOULDER AND INTO THE NEAREST GM DEALER AT MAXIMUM SPEED OF APPROXIMATELY 30 MPH. THE PROBLEM WAS DIAGNOSED SEVERAL TIMES RESULTING IN REWIRING OF THE THROTTLE BODY CONNECTOR AND FINALLY REPLACEMENT OF THE THROTTLE BODY AFTER THE THIRD INCIDENT OF THE SAME ISSUE. LOSS OF POWER AND UNABLE TO PROCEED AT MORE THAN ABOUT 30 MPH. *TT

I HAD JUST PURCHASED MY ENVOY A FEW DAYS PRIOR AND WAS ON MY WAY TO GET GAS. THE FUEL WAS LOW BUT THE FUEL LIGHT WAS NOT ON. WHEN I STOPPED AT A RED LIGHT, MY ENVOY DIED. THIS HAPPENED AT EVERY STOPLIGHT UNTIL I PUT GAS IN IT. THIS HAS HAPPENED MULTIPLE TIMES SINCE THEN. IT HAPPENS ANYTIME MY VEHICLE IS BETWEEN 1/4 TANK & EMPTY. THE FUEL LIGHT IS NOT ON WHEN THIS OCCURS. IT ALMOST SEEMS AS IF THERE IS NOT AS MUCH GAS IN IT AS THE FUEL GAUGE READS. IT HAS ONLY STOPPED ONE TIME WHILE I WAS ACTUALLY MOVING (AS I WAS COMING DOWN A RAMP TO GET ON THE INTERSTATE). IT DID NOT START BACK UP IMMEDIATELY WHEN I ATTEMPTED TO RESTART IT THAT TIME, BUT TOOK SEVERAL TRIES BEFORE IT STARTED. IT WILL LITERALLY DIE EVERY TIME I STOP UNTIL I PUT GAS IN IT. THERE HAVE ALSO BEEN A FEW TIMES WHERE I HAVE SLOWED FOR A RED LIGHT, THEN THE LIGHT TURNED GREEN SO I WENT TO ACCELERATE AND THE VEHICLE EITHER SPUTTERED AND FELT LIKE IT WAS NOT GETTING GAS, OR DIED COMPLETELY. LUCKILY, MOST TIMES I CAN PUT IT IN NEUTRAL & GET IT TO START RIGHT BACK UP WITHOUT HAVING TO PULL OVER. HOWEVER, I FEEL THAT HIS IS A SERIOUS SAFETY ISSUE FOR MYSELF & THE OTHER MOTORISTS TRAVELING BEHIND ME AS I TRAVEL VERY BUSY ROADS ON MY WAY TO AND FROM WORK. I HAVE LEARNED TO KEEP THE FUEL ABOVE 1/4 TANK BUT THE WAY THIS THING BURNS GAS, IT DOES GET LOW FROM TIME TO TIME BEFORE I GET TO THE GAS STATION. I DON'T KNOW IF IT'S A FUEL SYSTEM ISSUE OR IF THE GAS GAUGE IS INCORRECT BUT THIS NEEDS TO BE RECALLED BECAUSE IT IS DEFINITELY A HAZARD FOR MYSELF AND OTHERS. ADDITIONALLY, EVERYTIME I START MY VEHICLE SINCE IT HAS GOTTEN COLD, IT IDLES VERY HIGH - LIKE A LOUD HIGH PITCHED WHIRRING NOISE. IT THEN GOES VERY LOW AND ALMOST SPUTTERS. IT DOES THIS SEVERAL TIMES BEFORE LEVELING OFF AND SOUNDING 'NORMAL'. AGAIN, I DON'T KNOW IF THIS IS A GAS OR ENGINE ISSUE BUT I FEEL LIKE IT IS NOT GETTING GAS. *TR

WHILE DRIVING MY VEHICLE WITHOUT ANY NOTICE WHATSOEVER IT WILL JUST SHUT OFF RIGHT IN THE MIDDLE OF TRAFFIC. THIS HAS HAPPEN ON SEVERAL OCCASIONS. AFTER A FEW HOURS OF SITTING IT WILL START UP IMMEDIATELY. THEY HAVE NOT BEEN ABLE TO DIAGNOSE THE PROBLEM. WE HAVE HAD THE FUEL CANISTER, IGNITION SWITCH AND EVAP SENSOR ALL REPLACED IT IS DOING THE SAME THING. BY THE WAY I'VE HAD THE ENGINE REPLACED, THE TRANSMISSION REPLACED THE LEVELING BOOTS REPLACED AND STILL MAKING PAYMENTS. THERE WAS A RECALL ON THE FUEL SENDING UNIT AND THEY TOLD ME BECAUSE OF THE MILEAGE THEY COULDN'T REPLACE IT, BUT THEY HAD EVIDENCE AT 79000 MILES THAT IT WAS BAD BECAUSE I HAD IT DIAGNOSE FOR THAT SAME PROBLEM. FROM THE TIME I PURCHASED THIS TRUCK IT HAS BEEN NOTHING MORE THAN A NIGHTMARE. I PRAY SOMEBODY COULD GET ME SOME ASSISTANCE ON THIS TRUCK. *TR

MY GMC ENVOY DENALI 2006 USES UP TO 2 TO 3 QUARTS OF OIL IN A 30 DAY PERIOD. I HAVE NO LEAKS OR EXHAUST PROBLEMS. IT FINALLY COLLAPSED A LIFTER AND PUSH ROD. SAYS THERE IS NO NOTICE OR RECALL, BUT THE IS THE SAME ENGINE THEY USED IN THE 2003 PONTIAC, THEY DID RECALL THOSE MOTORS. DOES ANY ONE HAVE SOME HELP FOR ME? *TR

DRIVING ON THE HIGHWAY THE VEHICLE SUDDENLY READ EMPTY ON THE FUEL GAUGE, THEN THE PANEL SAID LOW OIL PRESSURE SHUT OFF ENGINE. I RAN OUT OF GAS ON A BUSY HIGHWAY PASSING LANE ALMOST CAUSING A BAD ACCIDENT WITH MY 5 YEAR OLD IN THE BACK SEAT AS I COULD NOT TELL MY FUEL LEVEL. THE FUEL GAUGE WOULD WORK SPORADICALLY OVER THE NEXT FEW DAYS AND THE LOW OIL PRESSURE WOULD GO AWAY AND COME BACK. WHEN I HAD THIS CHECKED OUT IT WAS THOUGHT TO BE THE OIL SENDING UNIT SO IT WAS CHANGED ALONG WITH THE FUEL SENDING UNIT. THE FUEL SENSOR WAS RESOLVED AT A COST OF $300 BUT THE LOW OIL PRESSURE CAME BACK ON EVEN THOUGH OIL WAS WELL MAINTAINED. SUDDENLY ON 3/1/2012 THE ENGINE RAN LOAD WHEN STARTED UP. I HAD TOWED TO THE SHOP WHERE (GM WHERE THEY DETERMINED THE ENGINE WAS NO GOOD. I HAD IT TOWED TO ANOTHER SHOP THAT DETERMINED THE ENGINE WAS NO GOOD AS WELL. I HAD TO PAY TO REPLACE THE ENGINE ALMOST $5000. I THEN LOOKED ONLINE FOR THIS ISSUE AND FOUND A WEBSITE TRAILVOY.COM (REPRESENT CHEVY TRAILBLAZER AND GMC ENVOY). HERE I FOUND 1000'S OF POST OF PEOPLE HAVING THE SAME ISSUES LOOKING TO FILE LAW SUITS AND WONDERING WHY WE CAN HAVE NO RECALL ON THIS DANGEROUS VEHICLE. THERE ORE 1000'S OF PEOPLE HAVING LOW OIL PRESSURE, DEAD ENGINES WITH LOW MILEAGE VEHICLES, RUN OUT OF GAS ON BUSY ROADS SUCH AS MYSELF AND MUCH MUCH MORE. THE GM ISSUES WE'VE EXPERIENCED AND ARE EXPERIENCING HAS BEEN HERE LONG BEFORE THE CURRENT ISSUES OF GM VEHICLES. HOW CAN WE GET SOMEONE WILLING TO HAVE THIS VEHICLE AND ISSUES ON THE RECALL LIST AND GET REIMBURSED FOR THE 1000'S OF DOLLARS SPENT TO REPAIR THIS VERY DEFECTIVE VEHICLE. IF A PETITION WILL DO IT PLEASE SHINE SOME LIGHT ON THIS. I HAD RECEIVED POST ON THE FORUM FROM NUMEROUS PEOPLE WILLING TO JOIN A CLASS ACTION SUIT AND MANY WERE CONSULTING ATTORNEYS ON HOW TO MOVE FORWARD WITH THIS. THIS IS A MAJOR ISSUE THAT WE DESPERATELY NEED THE NHTSA TO LOOK INTO. *TR

REDUCED POWER LIGHT CAME ON WHEN ON THE HIGHWAY. ALMOST GOT HIT BY A SEMI. THIS HAS HAPPENED MANY TIMES. THE ENGINE HAS ONLY 8K MILES SINCE ENGINE WAS REPLACED UNDER WARRANTY. *TR

FUEL SENSOR FAILURE IN THE GAS TANK. CAUSING THE FUEL TANK TO READ EMPTY WHEN FULL, CAUSING THE SUV TO STALL WHEN THE TANK IS FULL, CAUSING THE CHECK ENGINE LIGHT TO COME ONE. THIS IS A SAFETY ISSUE. *KB
