“If I have a sensor that will malfunction due to water then there should be a water indicator alert. My sunroof vent was blocked and water went into my trunk where the core module is. I had just come to a red light to turn on to a major highway and my car began to smell like fuel. I rolled down the windows and realized the smell was not as strong as inside. The light turned green and as I stepped on the gas the car went into limp mode as I was in the middle of my turn. The power steering then went out in the turn and the wheel yanked to the left and put me half way into the lane next to me. …”
