2005 GMC ENVOY Engine Problems

1) I just purchased the vehicle in Oct 2026 & 3 days after purchase, it broke down in Walmart parking lot due to, all the antifreeze pouring out. 2) December 2026 had to replace the front tires as they were stripped to the threads from rubbing against the fender wells. 3) January 2026 Wouldn’t start, wouldn’t turn over or anything. Had the ignition replaced. Ran fine for one week. 4) Currently won’t start. Broke down.

MY VEHICLE WHEN PURCHASED WAS ALTERED FROM CLOTH SEATS TO LEATHER BY THE DEALERSHIP WHERE PURCHASED. 3 DAYS AGO MY CAR IS SIGNALING ME TO SERVICE AIRBAG WHILE DRIVING THE CAR OR IN IDLE. SO I IMMEDIATELY TOOK IT TO A CERTIFIED MECHANIC AT MEINEKE AND WAS TOLD THAT THIS IS A MANUFACTURER DEFECT AND THERE IS A RECALL FOR THIS ON MY YEAR, MAKE & MODEL SUV. I CALLED GM ON 11/29/2019 AND WAS TOLD BY A SUPERVISOR NAMED ANGEL THERE HAS BEEN NO RECALLS BY THEIR MANUFACTURER AND THERE IS NOTHING MORE SHE CAN DO ABOUT THE MATTER. I CANNOT DRIVE MY CAR LIKE THIS KNOWING THIS CAN BE POTENTIALLY HARMFUL AND HAZARDOUS.

VEHICLE WAS STATIONARY AND IN DRIVE WHEN IT HAD A UNCONTROLLED ACCELERATION RESULTING IN A COLLISION WITH A GARAGE WHERE IT WAS BEING PARKED. EXTENSIVE DAMAGE RESULTED TO THE HOME AND VEHICLE. NO INJURIES.

MY SEAT COVERS WERE ORIGINALLY CLOTH BUT AT TIME OF PURCHASE THEY WERE REPLACED WITH LEATHER SEAT COVERINGS AND THERE IS RECALL #06V417000 HAS ME VERY CONCERNED.

RECEIVED A "CHECK ENGINE" LIGHT WHILE DRIVING THE VEHICLE. THE FAULT CODE THAT CAME UP WAS PO128 ( INSUFFICIENT AMBIENT TEMPERATURE - ECT ) UPON RESEARCHING THE PROBLEM I DISCOVERED THAT THIS IS A COMMON FAULT ON THIS VEHICLE. IT IS GENERALLY CAUSED BY A "STICKING" COOLANT THERMOSTAT. THIS CONDITION ALSO RESULTS IN POOR HEATING POOR HEATING OF THE PASSENGER COMPARTMENT. IF THIS IS SUCH A COMMON PROBLEM WITH VEHICLE AS I HAVE FOUND. GM SHOULD ISSUE A RECALL AND CORRECT THE PROBLEM AT NO EXPENSE TO THE OWNER!

I HAD THREE CARS IN FRONT OF ME STOPPED. I DID NOT SEE ANY BREAKL LIGHTS AND I HIT THE CAR IN FRONT OF ME PUSHING THE OTHER CARS TO HIT EACH OTHER. MY FRONT END OF MY CAR WAS SEVERELY DAMAGED BAD ENOUGH TO DAMAGE THE RADIATOR AND DESTROY MY AC UNIT. I'M NOT SURE WHAT ELSE WAS DAMAGED. IT SENT THE PERSON IN FRONT OF ME AND MYSELF TO THE EMERGENCY ROOM. " MY AIR BAGS DID NOT DEPLOY ". MY VEHICLE WAS MOVING ON A CITY STREET.

WHEN STOPPED IN TRAFFIC OR AT A STOP LIGHT, MY VEHICLE WILL IDLE ROUGHLY AND SOMETIME STALL. IT DOES THIS IN DRIVE, NEUTRAL AND PARK. I'VE HAD IT CHECKED AND THEY COULDN'T FIND ANYTHING WRONG. THERE ARE NO CODES SHOWING A PROBLEM.

ACCELERATING WHILE ENTERING A FREEWAY, TOOK FOOT OFF THE GAS AND THE VEHICLE CONTINUED TO ACCELERATE. APPLIED BRAKE BUT VEHICLE CONTINUED TO ACCELERATE.

THE OIL PRESSURE GAUGE IS READING ABOVE 80. HAD OIL CHANGED IMMEDIATELY. WAS TOLD THAT THERE HAVE BEEN COMPLAINTS REGARDING THE MIS READING OF THE INSTRUMENT PANEL. CONTACTED GM AND WAS TOLD THAT AT THIS TIME THEY ARE NOT COVERING THE REPAIRS AND THAT IT IS THE CONSUMERS RESPONSIBILITY TO REPLACE THE ENGINE SENSOR SYSTEM. GM HAS SOME OF THE RUDEST AND NASTIEST CUSTOMER SERVICE REPRESENTATIVES. I HAD TO CALL 3 TIMES IN ONE DAY. THEY EVEN HUNG UP ON ME . I SPOKE WITH [XXX], [XXX] AND [XXX]. I ASKED ABOUT THE SAFETY OF THE VEHICLE AND OTHER POTENTIAL PROBLEMS, SUCH AS ENGINE FIRE OR ENTIRE SYSTEM SHUTTING DOWN AND NOT RESPONDING.

IN MARCH 2012 I HAD MOTOR MOUNTS INSTALLED ON MY 2005 GMC ENVOY AT THE DEALERSHIP JAY GMC BUICK COLUMBUS GEORGIA. ON AUGUST 26,2013 THEY ARE TELLING ME I NEED NEW MOTOR MOUNTS BECAUSE OF THE AGE OF VEHICLE AND MILES THEY NEED TO BE REPLACE. I GUESS PARTS ARE OLD AND PROFESSIONAL INSTALLING IS OLD TO. DURING THIS SAME TIME HAD A TUNE-UP {MAJOR} AND NOW HAVE TO HAVE COIL AND PLUG INSTALL. THIS MAKE IT SEEM PAYING FOR PROFESSIONAL SERVE IS A WASTE OF TIME. MY FUEL INJECTOR ALSO NEEDS CLEANING AGAIN. IN THE FUTURE I CAN ONLY EXPECT 40,000 MILES ON ANYTHING FIXED BY DEALER. *TR

I HAVE BEEN READING A LOT AND IT SEEMS TO BE A COMMON PROBLEM IN THE 2005 SERIES GMC ENVOY, CHEVY TRAILBLAZER. BASICALLY THE COOLING FAN CLUTCH GOES BAD EASILY AND QUICKLY. WHEN YOU START THE ENGINE IT IS FINE BUT AFTER THE CLUTCH NEEDS TO ENGAGE IT EITHER CLICKS, AND DOESN'T ENGAGE OR IT JUST MAKES THAT COMMON JET ENGINE ROARING. THIS IS ALL TO COMMON AND GM NEEDS TO DO SOMETHING ABOUT IT. THERE HAVE BEEN PEOPLE WITH 40,000 MILES OR 140,000. I MY SELF AM ON MY SECOND ONE AND IT IS ALREADY DOING TO THE SAME THING AFTER 5 MONTHS. *TR
