RE: Engine System Service Urgent + Emission System Service Urgent
When the message appears your car is going into a limp mode, that's why it's riding so rough. When it does this your mechanic can pull the codes and tell you exactly what's going wrong. I don't understand why your dealer would just clear the codes without telling you what's wrong?
I highly recommend that you don't drive the car much until you find out what's wrong. You could damage your vehicle more by driving it with a system that isn't working properly.
