NHTSA Complaint #11497853 — 2018 JEEP WRANGLER

In right lane of US19 south bound at about 58 mph, experienced extreme frame vibration after driving over deterioration of asphalt portion of road (which I have driven over hundreds of times with no abnormal effect). Immediately de-accelerated and pulled over into the grassy area of the shoulder of the road. Got out to inspected vehicle, especially the front end structure and wheels for any sign of damage; I could find none. Carefully drove the Jeep home and again inspection the undercarriage of the vehicle for any sign of damage; none found. Took the Jeep into a local shop for extensive inspection of the the vehicle suspension, steering, tires, etc. for any indication of damage which would have caused the above situation; none was found. Even when I drove the Jeep after the situation, it drove normally. I had taken the Jeep in for the 48CHZ: Recall v88 recall on 20Apr20 and 48CHZ: Recall y95 (reconfiguration or power steering assist/ElectroHydraulic Power Steering (EHPS) calibrations) on 2Jul18. I am a retired Marine Corps Officer and I do not do any "off roading" driving with my Jeep, only normal Hi-way driving. I have done no modifications to the front end/lift of the Jeep. Therefore, I am concerned why I have experienced this condition; possible the "Death Wobble" even though I have had the recall "fix". I can only deduce that I experienced what was called the "Death Wooble" which the Jeep JL was experiencing when it first came out. My Jeep only has 27,318 miles on it. Thank you for your time in this matter and I look forward to receiving some form of response. Respectfully, [XXX] LtCol. USMC Retired INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
