While driving in the left lane on a particularly bumpy section of Interstate 5 South in Seattle (just before the NE 50th Street overpass), I had to quickly hit my brakes as traffic abruptly slowed. The Audie "Pre-sense" sytem did trigger, but emergency autonomous braking did not. My car did not slow down as I hit the brake, and I had to swerve onto the shoulder and put it in "B" mode to trigger full regenerative braking to stop the car. The weather was clear and the road was dry. I had previously had the vehicle in to the dealer as the brakes were making a load creaking sound, which they indicated was normal. The day after this most recent incident, the vehicle was towed (at the dealership's recommendation) in. It's been there for the past week and they are now claiming it is operating as expected.
