Consumer Description

While driving the active fuel management changed my truck from 4 cylinders to 8 cylinders. This is when I heard a loud bang and a bunch of lights came on the dash and my truck started shaking and shuttering. I was able to regain control of it, but I came close to crashing. I now require a whole new engine at 100000 miles. After talking to multiple shops this ks a known issue. While they dont always catastrophic fail, mine did and almost cost me to crash. This is a serious safety concern.
