My daughter was given an 06 sts 4 from her aunt. The car has 175000 miles on it and has been a solid car. We replaced the starter last year and shortly after the power starting stopped working. A mechanic told her that it would be 2000.00 to fix, sounded high to me and I don’t know what he said needed to be replaced. I think it is the pump and wanted to see if this is a common problem In these cars. Other than that it runs good, is it worth fixing?
