NHTSA complaint #11691368

Owner complaint summary

I am reporting a severe safety defect involving the engine and fuel injector system that began two months ago at ≈108k miles (now 109k miles). I have not yet taken the vehicle in for service due to the estimated high repair cost of $2,900. It is critical to note that the same underlying problem was subject to a safety recall for the 2017-2018 model years, but the defect was not fixed for my 2019 model year. This indicates a persistent manufacturing or design flaw that warrants an immediate investigation into my model year. The defect manifests regularly, causing a Cylinder 2 Misfire (P0302) and making the engine run very rough with a sudden and severe loss of power. This creates a direct rear-end crash risk due to the inability to maintain a safe operating speed. More dangerously, when the misfire occurs, the vehicle instantly disables critical driver assistance systems—Adaptive Cruise Control (ACC) and Lane Keep Assist (LKAS)—without any advanced warning. This malfunction is an unreasonable safety risk: CRASH HAZARD: The unprompted power loss and concurrent disabling of safety features create an immediate, dangerous situation. FIRE HAZARD: The persistent misfire strongly suggests a failed or stuck-open fuel injector, which causes fuel dilution of the engine oil. This contamination can lead to engine failure or, critically, a fuel leak onto hot engine components that poses an extreme fire risk. I urge NHTSA to investigate why this defect persists and to mandate a comprehensive recall to protect the public from this ongoing, life-threatening safety risk. The failed component may be available for inspection upon request.
