Glad I found this thread tonight. Just had the same thing happen on the way home from work and was kind of freaking out thinking something was on fire under the hood or even in the dash. Smelled really bad in the cab so rolled the windows down but that didn’t even help it was so strong. Oil pressure was very low and the exhaust sounded different, almost like maybe an exhaust leak. Guess I’ll give another 1k miles before I get too concerned. Dealer should definitely tell people about this. I almost pulled over on the side of the highway so that I didn’t do some kind of engine damage.
