NHTSA Complaint #11500466 — 2018 JEEP WRANGLER

I purchased my 2018 Jeep Wrangler 4 door Saharah Unlimited summer of 2022. The vehicle had less than 10k miles on it when I purchased the vehicle. Vehicle runs really well and alignment seems to be perfect. But occasionally at freeway speeds, usually anytime above 40mph. If I hit a bum (even road reflectors), either on a straight road or in a turn. I'll get a really violent shaking. I can get the shaking to stop by slowing down and applying gentle braking with reducing speed. Checked all the suspension connections and seemed tight. But again at speeds usually above 40mph, if I hit a bump or in a tight turn the violent shaking will occur. I've put less than 5k on the vehicle since purchase and the problem still exists. The vehicle is stock, stock tires, and never been offroad. I have changed out the steering dampener and track bar (heard most common problem). But still have this death wobble. Were nervous to take the vehicle on any long road trips with this issue. I saw online possible issues with possible weak welds for the steering mounts (track bar). We really love our Jeep, but not trust taking any long trips out side of where we live.
