My 2021 Kona has undergone five separate oil consumption checks. The engine is depleting oil at an abnormal rate, creating a clear risk of sudden catastrophic engine failure and highway stalling. Dealership service personnel have repeatedly dismissed consumption data despite documented top-offs between 500 and 1,000 miles. Furthermore, this vehicle has already required an entire brake system replacement due to unidentifiable system failures, establishing a continuous history of substantial defects impairing its safety, market value, and use.

I am the original owner of 2021 Kona Limited under warranty. The dealership refused to help me after my car lost oil, citing one missed service from over three years ago. That gap was due to a severe family medical emergency where my partner was hospitalized off and on for over three mon

"The vehicle suffered sudden internal engine failure while in operation due to catastrophic oil starvation, presenting a severe risk of engine stalling and loss of propulsion on the road. Active diagnostic codes are P0014, P0017, and P0303. An independent mechanic confirmed the engine was found 3 quarts low on oil with absolutely no external leaks or pooling under the vehicle, indicating massive internal oil consumption. This vehicle has been meticulously maintained with 11 consecutive oil changes logged between 15,202 miles and 115,926 miles. This oil loss starved the hydraulic timing components of fluid pressure, causing immediate timing failure. The manufacturer's current safety recall ca
