Did you have the A/C on? The A/C cycling on will kick the RPMs up. Anyway if you feel the jolt again quickly look at what the RPM gauge is showing.
I had this same thing happening on an older AWD car occasionally. Could have sworn someone was tapping my rear bumper. But concluded the power output was fluctuating for some reason. Perhaps related to how during a cold start the vehicle RPMs are elevated for a short time until partially warmed up. Pressing the brake harder prevented the increased power from overpowering the brake pressure. Or put the transmission in neutral at stops.
