This very dangerous defect is a result of poor engineering and negligence on the part of Mercedes-Benz. There is no telling what new defects are latent in the new cars. By the way they have tried to weasel out of their responsibilities on millions of defective vehicles, you can count on them continuing doing so in the future.
Everyone should file complaints with the NHTSA (see the site above, it has a link to the NHTSA) but no one expects them to do much as they are politically controlled.
