serious safety-related defects in my 2023 Kia K5 involving the fuel/emissions system &other vehicle components. From early ownership & throughout the lease period, the vehicle experienced repeated& unresolved issues including fuel system abnormalities, emissions failures, fuel odors, check engine light activation, abnormal noises, &performance concerns consistent with fuel pressure or fuel tank-related problems. I reported these issues multiple times to the dealership &to Kia Consumer Affairs beginning well within the first 24 months of the lease, continuing for over a year. Despite repeated complaints and service visits, the vehicle was repeatedly returned to me- deemed safe to drive, my concerns were ignored. In June 2024, the dealership identified fuel tank expansion, confirming the same safety concerns I had been reporting. In November 2025, Kia issued Safety Recall SC356 (NHTSA Recall No. 25V794), stating that a damaged check valve can allow air to enter the fuel tank, causing expansion, contact with hot exhaust components, melting, and increased fire risk. My vehicle is included in this recall, which remains incomplete, &I was never notified while the defects were actively occurring. Prior to the recall and before the fuel tank expansion was diagnosed, I paid significant out-of-pocket costs in March and April 2024 for emissions-related repairs based on representations that the vehicle was safe to drive. This vehicle was intended as a graduation gift for a minor, & minors in my household regularly operated it. Kia’s continued assurances that the vehicle was safe, despite known and reported defects, placed my family, especially minors, at serious risk of injury or death. In addition to fuel/emissions issues, the vehicle had persistent seat defects and other unresolved problems that were never fully repaired. The manufacturer ultimately acknowledged the vehicle is irreparable. The recall confirms the safety concerns.I raised were valid and serious.in shop 600days
