So, I have a 2009 Eos Komfort. While we were driving it felt like we had a flat tire. We immediately stopped and checked but no flat. We kept driving and it kept doing it so we took it to the shop. They found that our rear tires were down to the wires on the inside so we replaced them with brand new ones. They also checked everything underneath and said all was solid. We have now driven it for a couple of weeks with no problems until yesterday. On an hour long trip it started doing it again. It is usually after the car is warmed up. It sounds like a flat and the car will shimmy and shake and the steering wheel will jerk to the left a little. We are taking it on a trip of 3000 miles in a few weeks and need this resolved asap. Any suggestions?
