I am writing to formally express my frustration and concern regarding an ongoing issue with my 2021 Jeep Wrangler Unlimited. For several years, I have experienced severe shaking in my vehicle when driving at speeds between 50-70 mph after hitting a minor bump. The vibrations are so severe that it feels like the vehicle is going to shred itself in half. The issue has gotten worse over the years. Once this occurs, it requires rapid deceleration to 40 mph for the issue to subside. Most concerning is that on [XXX], this shaking occurred twice while driving in heavy traffic on [XXX] with my [XXX] son in the back seat. The severity of the issue poses an undeniable safety riska”not just to me and my passengers, but to others on the road as well. Given Jeepas reputation for durability and off-road capability, it is deeply disappointing that such a serious issue is not being addressed with more urgency. After the event on [XXX], I initially addressed this issue with a Jeep service center at Dellen Chrysler Jeep and Dodge in Greenfield, IN. I was informed that the problem was related to the steering damper. However, despite recognizing the issue, my vehicle has yet to receive the necessary replacement due to a nationwide shortage of the part more than 2 months later. I implore someone from Dellen, Jeep, and/or NHTSB to do the right thing and properly warn owners about this serious safety issue. As a consumer and Jeep fan, it is unacceptable to me that: 1) A vehicle fails this catastrophically during normal driving, putting the public at risk. 2)Jeep doesnat have sufficient inventory to fix the problems. 3)Jeep isnat doing anything to make owners aware of this seriousness of the issue.
