In the fourth episode of Car Trek series 6, the guys leave the cornfields of Kansas and head out to summit America's most famous mountain road, Pikes Peak. But along the way, a few things happen. Ed's Mercedes-Benz S55 AMG is just as broken as it started out, Freddy's Lexus LS400 develops a common yet annoying fault, but Tyler's Tesla Model S P85 completely gives up, despite having every indication of being charged. Elon Musk may want to skip this video.
