problems, problem.... need help
I had a very similar issue. On the highway doin about 75mph I noticed a very pronounced vibration, like a tire rapidly loosing it's air while at speed. I immediately pulled over, but had no flat. Perplexed by what just happened, I walked around the car and noticed a smell coming from the rear which led me to believe this was brake related. I fiddled with the parking brake and it turns out it wasn't fully releasing and needed adjusting. While holding the release handle, I just tapped the parking brake a bit which temporarily resolved it and drove off until I got it adjusted. I was able to replicate as well.
