Having an excellent experience with a 2007 Hyundai Veracruz, I helped my daughter purchase a used 2017 Tucson with 90,000 miles in June of 2022 from a Toyota Dealer who did not inform us of any issues. In late August then engine began to make a knocking noise. Took it to a local reputable mechanic who said that she needed to not drive it and have it towed to a Hyundai dealership as soon as possible. The earliest appointment was October 13th. Needless to say that the Tucson has been in the shop since then and Hyundai finally gave the approval to replace the engine after several exchange of emails and pictures with dealership. They have not been able to give us an update. It will be 5 months here in March. Very frustrating. Any suggestions???
