The PPF problem with Hyundai Tucson & Kia Sportage petrol/mild hybrid models remains a point of contention. Hyundai/Kia have been working on a software update without much success and have been pointing the blame at the owners of the cars!
Hyundai/Kia have recently released the 2025 model year, that have slightly tweaked engine specifications, which is rumoured to have revolved the issue, especially as these cars have being released early and MY24 skipped.
The important thing is, whilst all petrol cars require a PPF, so there’s always the potential, Hyundai/Kia have a known issue with Tucson/Sportage, which has been recognised by both manufacturers as a fault.
