I would like to know if anyone has experienced this problem. While driving 50+mph sometimes when hitting a bump car goes into a violent chatter. You have to slow down to about 20mph for it to stop. Sometimes hitting another bump will make it stop. Flooring it will make it stop. Has been to dealer once. They had it for 2 weeks and said they couldn’t get problem to repeat. When I picked it up it did it to me 5 miles from the dealer. I have a video of it if I can figure out how to upload it.
