Consumer Description

Driving fine at low speeds (under 40mph), once I accelerate to highway speeds the engine misfires, check engine light flashes, Smart City Brake System Malfunction, Radar Malfunction, and car losses all engine power. Car just coast, lights and brakes still work. Check engine code moves around and will be on cylinder 3 sometimes and cylinder 4 other times. Able to replicate this issue multiple times. Serious safety concern.
