NHTSA complaint #11728299

Owner complaint summary

I am the original owner of a 2023 Jeep Wrangler Sport with approximately 16,240 miles. The vehicle is completely unmodified. I am reporting a serious safety defect involving the steering and suspension system. When driving at highway speeds (50 mph and above), the vehicle experiences a violent front‑end oscillation whenever it encounters a bump, uneven pavement, or bridge expansion joints. The steering wheel rapidly shakes left to right, and the entire vehicle shudders for 5 to 10 seconds. The oscillation does not stop until I slow the vehicle down to below 45 mph. This issue is reproducible and occurs frequently on rough or uneven road surfaces at highway speeds. During these events, I temporarily lose the ability to maintain proper steering control, creating a dangerous situation for myself, my passengers, and other drivers. This condition is commonly referred to as “Death Wobble,” and it makes the vehicle unsafe to operate. Given the severity of this defect and the safety risk it poses, I am requesting that NHTSA investigate this issue and that Jeep/Stellantis address the defect under the New Vehicle Limited Warranty (3‑year/36,000‑mile basic warranty). The front‑end suspension components—including the track bar, steering damper, ball joints, and related parts—should be inspected and repaired as necessary to eliminate this hazardous oscillation.
