I took the car to Hyundai several times, one mechanic would say I had bad front tires that were not balanced. OK, got them balanced, no help. Next mechanic said my tires were not round, and that I needed new tires. OK, got new tires, same problem. Next mechanic said I had bad brakes. OK, got new brakes, problem still there. Of course none of these fixes were covered by the warranty. I think Hyundai knows the problem and just did not want to put any of their money into fixing it. I will never buy another piece of Hyundai junk.
