ENGINE AND ENGINE COOLING:COOLING SYSTEM

THE INTAKE GASKET FAILS AFTER ABOUT 4 YEARS OF SERVICE. I AM TOLD THAT IT IS DUE TO THE POOR DESIGN OF THE GASKETS AND THE EXTENDED LIFE ANTI-FREEZE USED IN THE VEHICLE. THE FAILURE OF THE GASKET ALLOWS ANTI-FREEZE TO MIX WITH THE OIL WHICH CAN CAUSE DAMAGE TO THE ENGINE IF NOT DETECTED. THIS IS A FAIRLY COMMON PROBLEM. I PERSONALLY KNOW OF 3 FAILURES OF THIS GASKET. THE ANTI-FREEZE ALSO DEGRADES SOME FITTINGS THAT GO INTO THE INTAKE.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

THE FIRST REPORTED ITEM: SHOULDER BELT ANCHORS, 3 OF THE SHOULDER ANCHORS HAVE COME LOSS, THE FIRST CAME COMPLETELY OFF, AFTER NOTICING, I REGULARLY CHECK AND TIGHTEN. THERE APPEARS TO BE NO MECHANICAL LOCKING DEVICE TO KEEP THIS FROM REPEATING. THE SECOND ITEM REPORTED IS THE EXHAUST LEAK. THE DEALER REPEATEDLY HAS FIXED THE SAME LEAK, IT FILLS THE VEHICLE WITH FUMES AND IS DANGEROUS. I FINALLY REPLACED THE EXHAUST MANIFOLDS AT MY EXPENSE TO MAKE THE VEHICLE SAFE. THE FAILED COMPONENT WAS ALWAYS THE EXHAUST MANIFOLD TO "Y" PIPE GASKETS. THE THIRD COULD HAVE BEEN DISASTEROUS, THE THROTTLE CABLE FAILED LEAVING THE VEHICLE STUCK AT FULL THROTTLE.

PROBLEM WITH BRAKE FAILURE FROM DAY ONE. 1ST:ORIGINAL POWER STEERING PUMP THAT CONTROLS THE BRAKE PRESSURE WAS REPLACED WHEN PULLEY SHAFT BROKE. LOST ALL POWER AND BRAKING ABILITY WHEN THE PUMP SHAFT BROKE. NO BRAKES NO STEERING. 2ND: SINCE INITIAL PURCHASE I HAVE HAD PANIC BRAKE FAILURE. WHEN BRAKES ARE REQUIRED AT PANIC STOP, THE BRAKE PEDAL WILL GO ALL THE WAY DOWN TO THE FLOOR. BRAKES BECOME INACTIVE UNTIL PRESSURE BUILDS UP AND PEDAL REGAINS ORIGINAL HEIGHT. AT THAT TIME THE BRAKES WILL BECOME ACTIVE AND START TO SLOW THE VEHICLE. THIS ALMOST CAUSED ME TO HIT SOMEONE WHO JUMPED INFRONT OF MY VEHICLE. SWERVED TO AVOID INCIDENT. HAVE SPOKE TO DIFFERENT DEALERS AND ALL SAY THAT THAT IS NORMAL AND NOTHING CAN BE DONE. I HAVE SPOKEN TO OTHER SUBURBAN OWNERS WHO ALSO HAVE EXPERIENCED THE SAME PROBLEM AND ALSO TO NOTHING WRONG. 3RD PROBLEM IS WITH STEERING SYSTEM IS TOO LOOSE. TRUCK WANDERS AT HWY SPEEDS. MUST CONTINUALLY READJUST STEERING BACK AND FORTH.

THEN HAD TO TAKE IT IN AGAIN AND THEY REPLACED THE REAR AIRCONDITIONER. WE PURCHASED THIS TRUCK TO PULL A 20 FT TRAILER THE TRAILER WEIGHS 4200 LB. THE SUBURBAN HAS A 3.73 DIFFERENTIAL AND THE TRAILERING PKG. PLUS POST TRACTION OR WHATEVER THETY CALL IT NOW! WE WENT ON A VACATION IN NOV. PLANNING ON BEING HOME THE 1ST OF THE YEAR. OUR !ST DIFFERENTIAL BROKE OUTSIDE OF FREDERICK MD. IT WAS REPLACED. UPON TRYING TO RETURN HOME THE 2ND DIFFERENTIAL BROKE! IT WAS REPLACED IN LOUISVILLE KY. CONTINUNING OUR VENTURE HOME. THE 3RD DIFFERENTIAL WENT OUT IN MOBILE ALA. THEY GAVE ME A VERY DIFFICULT TIME. TOLD ME IT WAS MY FAULT. I WAS EITHER GOING TOO FAST OF THE TRAILER WAS TOO HEAVY. NEITHER ACUSATIONS WERE TRUE! UPON FINALLY ARRIVING HOME (ALMOST) THE 4TH DIFFERENTIAL WENT OUT AND REPLACED. I HAVE LOST ALL FAITH & TRUST IN THIS VECHICLE. AM SCARED TO DEATH TO TAKE IT ON THE ROAD. MY HUSBAND IS 67 YEARS OLD AND HAS DREAMED OF HIS RETIREMENT ALL HIS LIFE. NOW WE ARE STUCK WITH A SUBURBAN WE DON'T DARE TAKE ON THE ROAD FOR FEAR OF IT BREAKING DOWN AGAIN. CHEVROLET REFUSED TO DO ANYTHING ABOUT IT. THE GARAGE WE PURCHASED IT FROM HAS BEEN VERY NICE. HOWEVER, THEY ALSO HAVE BEEN NO HELP IN THIS ISSUE!
