Required replacing lower seat cover. $500 bill. Common problem with this faux leather seat. Dealer referred me to another place charging $900 for whole seat cover only option.

Anonymous, NY (2014 Mercedes-Benz E-Class E350 3.5-L V6)"Wipers "stutter" when in use. In other words, they do not move smoothly across the windshield but rather in a jerky movement. The dealer has tried adjusting them, putting on different wiper blades, and nothing has helped. The dealer finally conceded that they had done all they could do."
