I recently purchased a 2015 RT L with 500 miles on it. It was a private sale. When I got it back home, I took it to my dealer for an inspection. They said everything seemed good to them. So I have put on another 500 miles. However when riding I feel like I am smelling exhaust fumes. It doesn't seem to matter what speed, so I am assuming it is filtering in from the rear airflow dynamics somehow! Anyone ever had this experience and if so.....what is to be done? Also if no one has experienced this....I am interested in suggestions of what steps I should take to check it out further or resolve the issue! Thanks in advance.
