I was driving on a side street, heard loud noise coming from left front wheel area when I heard a grinding sound and car was riding rough. Called for help. Instructed not to drive vehicle till it was looked at by a mechanic. Mechanic who evaluated and repaired vehicle said he has never seen "pitted wheel bearings" in 30 years of operation. He gave me back the faulty bearings and told me I should contact you and the corporate area of Hyundai, because this is a serious safety issue and warrants an alert or recall. The driver side lower ball joint and bearings had to be replaced. Please review ASAP, as this is a serious safety concern for the rest of the population. Thank you!.
