I have a 2000 sonata. I brought it to Mienke today because everytime I bring my car to a hyundai dealership, they give me a laundry list of maintenance care or repairs they think I need. My car felt like it was skidding on ice and it was making loud banging noises. My car's front end for the last 2 years has been knocking and shaking but nothing this bad. Mienke told me that my sub frame was all rusted out and my engine was falling out. I will call Hyundai tomorrow to see if they will fix it because this is a huge defect as I have been reading.
