I have a 2018 sonata. It has thrown a p1326 code. There is a TSB for that code where the dealership will Check to see if the engine will Be replaced. My car passed that test meaning no engine replacement. My car has 107,000 miles on it and has had regular maintenance. In between oil changes Iam having to add oil. Iam spent hundreds on engine oil since taking owenship of the car. There is obviously an issue with the engine since there is a TSB. Yes my car passedapassed the test this timea (Iam having to pay $600 to replace the knock sensor). I feel like Iam driving a ticking time bomb and money pit. I feel as though Hyundai should handle this known issue. I need help.
