Open the full vehicle complaint log (all categories)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.
On three occasions, while in regenerative braking mode, my car failed to engage the brakes at low speeds. After pressing on the brake pedal for several seconds with no response, the wheels then locked completely - but only after the car had traveled had traveled around 30 feet. The dealer has inspected the car and has not been able to replicate the problem, so they say there is nothing they can do to correct it (although they are NOT saying that they don't believe me). There were no warning lights or messages about a failed system - the brakes just didn't work. This was very unnerving to me, and I don't see how I can drive the car without some corrective measures taken. I was fortunate that these incidents happened where no person or other car was nearby, but that was only luck. I reported the three incidents to the dealer, and brought the car in twice for them to inspect the car.
