“I find myself in this situation due to a defect in my 2023 Hyundai, which is under Full Factory Warranty. I have had all my required services completed by Hyundai on time, and as the consumer had no idea anything was wrong with my vehicle.

I then got a parts store to clear the code and the vehicle has been fine since. I did a quick internet search and apparently this is very common and lots of owners have this happened multiple times a year and the dealer has no fix or intention of a fix”

The dealer diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 1,520.”
