2009 HYUNDAI GENESIS User Comment / Complaint

My new gensis 4.6 the top of the line standard bearer started to have abnormal metallic slapping and clunking noises at 1500 miles. This in turn caused the rear end to have some play and some gear whine. The dealer and the HYUNDAI trained tech did not have the answer. A new HYUNDAI GENSIS 4.6 was test driven and I was informed that this is normal for rear drive cars.After four visits I found out there are no parts or adjustments for this.I was not told the complete truth from the get go and they do not allow independent opinions.The dealer and HYUNDAI factory service have treated me as a non issue.My retire car and I have been STIFFED and hung out to dry.
