NHTSA Complaint #11462068 — 2021 JEEP WRANGLER

The exact cause on my vehicle is currently unknown, but this is definitely a suspension & steering related issue. There are numerous previous reports of what I have had occur to me "death wobble" multiple times now in Jeep Wrangler forums and YouTube online. We can reproduce with video of the issue. The Jeep forums indicate that it is usually suspension/trackbar/control bar/bushing/or improperly tightened bolts on these suspension areas. I have taken to two different dealerships within a two week period who have inspected these components and not found anything abnormal. The problem occurs when driving at speeds between 45 and 70 mph and driving over a small bump, bridge transition, expansion joint. The entire vehicle begins to shakes violently, including the steering wheel. You can only recover by pulling over to side of road to complete stop. This is extremely dangerous in construction zones, rush hour/high traffic situation. The vehicle has been inspected by two separate Jeep dealerships. Both were aware of the problem being experienced occurring on other Jeep Wranglers, known as "death wobble". Neither dealership found a problem in their inspection. The first dealership could not reproduce on their road test. After getting car back, we drove approx. 30miles on highway and the problem occurred two times in that distance, both times over bridge transitions. We then took to second dealership. The second dealership said they did feel something in the steering, but nothing violent or unsafe during their road test. They are ordering a steering dampener replacement part, but is on back order for 2wks+. There are no warnings or other symptoms of the problem prior to the failure. My wife and I first started to experience a steering bump at around 20k miles (a couple thousand miles after purchase).
