NHTSA Complaint #11572997 — 2021 JEEP GLADIATOR

See video of incident here: [XXX] Additional video is here: [XXX] The incidents happened while driving on the interstate at approximately 70mph. When a normal expansion joint or bump was traversed, the steering wheel would suddenly oscillate continuously, with the degree of the oscillation growing more severe over time. The entire body of the vehicle shook violently. The only way to recover from the severe oscillation was to reduce speed substantially - generally to below 40 mph - or to encounter another bump to upset the oscillation. We took the Gladiator to a local Jeep dealership. They stated they replaced the steering damper and that the manufacturer had updated the part number (the failed damper was the old part number). However, we still feel a looseness in the suspension that we did not feel previously with this vehicle. When traversing bumps at speed, sometimes the oscillation can still be felt, but it is not continuous as shown in the videos. We suspect the steering damper may have been damaged to due another loose or failed component that is still in service on the vehicle. The vehicle is stock and has not been modified previously.
