WE HAD IT RECONDITIONED AT THIS DEALERSHIP LAST YEAR, SPENDING $4000.00; WE HAD IT INSPECTED AT THIS DEALERSHIP WITH THE MASSACHUSETTS VEHICLE CHECK; IT PASSED THE FRONT END CHECK AND FRAME CHECK ON 8/4/17. I WAS DRIVING THE VEHICLE IN LATE DECEMBER, AND HIT SEVERAL DEEP POTHOLES CAUSED BY AN ICE STORM; SHORTLY THEREAFTER I LOST STEERING CONTROL OF THE VEHICLE. I HAD IT TOWED TO ALDEN BUICK/GMC IN FAIRHAVEN, MASS. TO BE TOLD THAT THE ENTIRE FRAME HAD COLLAPSED DUE TO EXTENSIVE CORROSION AND RUST. I HAD IT TOWED TO ROBERTSON'S GMC IN WAREHAM AND FILED A CLAIM WITH COMMERCE INS. CO. TO HOPEFULLY COVER THE DAMAGE TO THE FRAME; COMMERCE DENIED THE CLAIM STATING"THE FRAME ASSEMBLY WAS SEVERELY ROTTED AND THIS EXTENSIVE ROT ALLOWED THE RIGHT FRONT CONTROL ARM TO BREAK AWAYFROM THE MOUNTING POINT ON THE FRAME RAIL. GMC ISSUED A TECHNICAL SERVICE BULLETIN STATING THAT SOME ENVOY MODELS SUFFERED FROM EXTENSIVE FRAME CORROSION. WHY DID ROBERTSON'S…”

“DEAR SIR/MADAM, I HAVE A 2003 GMC ENVOY SLT MODEL 4.2L V6 4WD AND AS I WAS BACKING INTO MY GARAGE I HEARD A LOUD BANG AND WHINNING NOISE AND I NOW HAVE NO REVERSE GEAR AND WHEN I SELECT THE DRIVE GEAR ON THE AUTOMATIC TRANSMISSION I HAVE A WHINNING NOISE, I HAVE READ THE BLOGS ON THIS ISSUE AND I BELIEVE THAT GM AND GMC ARE VERY AWARE OF THIS PROBLEM, THIS REPAIR WILL COST ME UP TO $2,800.00 PLUS TAX TO HAVE THE TRANSMISSION REMOVED AND A RE-MANUFACTURED ON REPLACED ON MY VEHICLE. I WAS JUST GLAD THAT THIS MATTER HAPPENED AT MY RESIDENCE AND NOT ON SOME BACK ROAD IN WEST VA., I BELIEVE THAT AS STATED, GM AND GMC IS VERY AWARE OF THE PROBLEM WITH THE 4L603 TRANSMISSION THAT WERE USED IN THESE VEHICLES' AND THE PROBLEM WITH THE SUN-SHELL AND THE REACTION SUN GEARS THAT ARE LIKE A GRENADE EXPLODING INSIDE THE TRANSMISSION. I WOULD LIKE FOR A RECALL TO BE STARTED ON THIS PROBLEM AND THE OWNERS TO BE PAID BACK ON ALL OF THESE REPAIRS. THE CONSUMER STATED THE AIR RIDE SUSPENSION THAT WAS INSTALLED ON THE VEHICLE IS DANGEROUS. THE AIR RIDE SUSPENSION DEFLATED ON BOTH SIDES ON THE REAR OF THE VEHICLE, WHICH CAUSED THE VEHICLE TO BOTTOM OUT ON STOPS. UPDATED 07/08/15”

“WAS INSPECTING CAR AND HAD SEVERAL COMPLAINTS TO DEALERSHIP THAT FRONT END HAD A STRANGE NOISE WHEN WE GO OVER A ROUGH ROAD. WHILE TRYING TO FIGURE OUT WHERE FUEL SMELL IS COMING FROM I NOTICED A CRACK ON THE WELD NEXT TO THE SHOCK MOUNT . I ALSO NOTICED THAT THERE HAS BEEN A PREVIOUS REPAIR THERE BECAUSE WE HAVE HAD THIS CAR SINCE IT WAS NEW ALL I CAN THINK IS THAT THEY SAW THIS AND DID A REPAIR AND NOT TELLING US SO IF YOUR CAR IS CREAKING CHECK THE FRONT END COULD BE FALLING APART.”
