So, I'm on an onramp coming "up to speed" on a right "loop" onto the highway and suddenly it feels like someone is applying and releasing the e-brake. The car hesitates, takes off, hesitates, takes off, about 6 times during the curve. This is the 2nd time this happened in the past two weeks. The first time it wasn't nearly as severe and actually felt like the car was in some crosswinds or something so I didn't give it much thought the first time. In any case, once back "straight" the car is fine. I'm leaning towards a wheel bearing but that seems extreme at 26,000 miles. Any other ideas?
