I've done a video on the most reliable Mercedes AMG Car ever built, I've made one on the best turbo diesel Mercedes ever made and I've made a few on factory defects. This is the story of the least reliable AMG ever made, the M156 6.3 Liter V8. The first engine built from the ground up by AMG didn't exactly pan out in the reliability department and in this video, I'm going to prove it to you. Enjoy and stay to the end to find out why I just bought a car with this ticking time bomb and why I think the M156 is still a total legend.
