NHTSA Complaint #10315994 — 2007 GMC YUKON

I PURCHASED A 2007 YUKON AND SINCE THAT TIME I HAVE HAD THE REAR AXLE BEARING REPLACED 2 TIMES AT 43K MILES AND AGAIN AT 93K DUE TO A HUMMING NOISE EXTREMELY LOUD. AGAIN THE NOISE RECURRED AT 123K MILES I RETURNED TO DEALER THEY REFUSED TO DIAGNOSE THE PROBLEM BECAUSE THE WARRANTY WAS EXPIRED AT 100K. I MENTIONED THAT THE NOISE RETURNED FOR THE 3RD TIME. II CONTINUED TO DRIVE THE VEHICLE AND A FEW DAYS LATER WHILE DRIVING ON THE FREEWAY W MY DAUGHTER THE CAR LOCKED ( DIFFERENTIAL). THE DIFFERENTIAL GEARS BROKE..I HAD IT TOWED BACK TO THE LAST DEALER THAT REPAIRED VEHICLE AND THEY MENTIONED IT WAS OUT OF WARRANTY ( WHICH IS WHY THEY COULDN'T INSPECT IT UNLESS I PAID). I THEN TOOK IT TO MY HOME DEALER WHERE CAR WAS PURCHASED AND THEY DISCOVERED AN INTACT SCREW WHEN THEY REMOVED THE COVER FROM DIFFERENTIAL. MECHANIC NOTED THAT THE PREVIOUS DEALER THAT WORKED ON VEHICLE MIGHT HAVE NOT TIGHTENED BOLT CORRECTLY SINCE BOLT HAD NO DAMAGE OF THREADS AND WAS INTACT. I THEN CALLED GM CUSTOMER SERVICE AND THEY REFUSED TO CORRECT PROBLEM. SERVICE DIRECTOR DID MENTION THAT AXLES COULD HAVE SHOT OUT AND CAUSED FATAL CRASH KEEP IN MIND MY DAUGHTER OF AGE 6 WAS IN THE CAR.DEALER (HOME DEALER) STILL HAS VEHICLE AND DEALER THAT LAST REPAIRED REFUSES TO CORRECT PROBLEM. IT HAS BEEN 1 YEAR AND 1 MONTH SINCE LAST REPAIRED AND MENTIONED IF NOT TIGHTENED PROPERLY IT WOULD HAVE ALREADY CAUSED PROBLEM BY NOW. PLEASE ADVISE IF I HAVE ANY ALTERNATIVE COURSE OF ACTION THE REPAIRS EXCEED 5000.00 DOLLARS NOT INCLUDING ANY DAMAGE TO THE TRANSMISSION WHEN DRIVE SHAFT LOCKED ... *TR
