Driving slowly in a parking lot, went over a speed bump and the car suddenly started to shake/rumble and the brakes did not work. Almost hit the car infront of me. Very forcibly, applied brakes again which did stop the car. Just did a Google search and others have reported same issue and one suggested to file this complaint with you as apparently Hyundai is doing nothing about it. Car has just over 3000 miles on it and we have had no other issues. We have not brought it to service as it has just happened today. No warning lights came on. This is copied from a post 5 months ago: Hyundai corporate has told me that, upon testing other Palisades, they have discovered that this happens in ALL 2024 Palisades". I do not think this is a safe "idiosycrysity" that all Palidades should have.
