So, new to me 15 Legacy Limited, 106,000 miles. First snow drive in it last night. Was on the highway and 2 times, it felt like the brake was tapped, like just a quick grab, and then it was fine. I thought it might have been from the snow. Today on the way to work, roads were clear, about 15 miles into my drive, it did it again. Only once. Is this a CVT issue? Its just a split second, but it feels like you just tapped the brake pedal, then its fine.
