Consumer Description

While driving, the check engine light came on. Soon after, the rear floor of my 2021 Kia K5 lifted upward, and I noticed the fuel tank underneath had swollen. When I opened the gas cap, it blew off with force and gasoline sprayed on me, soaking my clothes. This could have caused a fire or explosion. The car is now unsafe to drive, and the rear seat cannot be used because the floor is deformed. I discovered that Kia has a Voluntary Emissions Service Campaign SC288 addressing this exact issue (fuel tank swelling and excessive pressure due to a faulty PCSV valve and EVAP system), but this is clearly a safety hazard, not just an emissions problem. Many other owners have reported the same issue online. I believe this defect should be escalated to a safety recall before someone gets seriously injured or worse.
