Engine complaints
Fuel is not delivered to firing chamber due to failure of fuel pressure sensor. This will cause engine to shut off when on the road. No obd-ii code is present since the failure of the fuel pressure sensor will put the car in protected mode, no code can be read. When engine is shut off, it will have no power to steering or brake system, put driver in a very dangerous situation. I was lucky enough to find out after arriving home. The problem appeared the next morning.
