2020 Jeep Wrangler Unlimited suspension problems

“At highway speed when hitting even a small bump or road irregularity, the Jeep experienced the notorious "death wobble". Oscillating shimmy and momentary loss of control. I discovered the steering damper was blown out on the track bar. After looking into the technical service bulletins, I found that I have the aluminum steering gear box described in TSB-08-074-20. I took my vehicle to the dealership to have this investigated and they agreed that the aluminum steering box caused the excessive force on the damper and steering components and needs to be replaced. However, since this is not covered under warranty, they are charging me for the repair of a well known and documented FACTORY DEFECT. I applied for goodwill repair and was denied. It is terrible that this should have been a recall and I am stuck paying the bill. But even more so, this is a SEVERE SAFETY ISSUE and is not a matter of if it will happen, but when it will happen. No one should be subject to losing control of their vehicle at highway speed due to a KNOWN DEFECT.”

“When driving down the road, 55mph, I drove across some bumps in the road, and my steering, tires and the front of my Jeep started shaking violently. Couldn't hardly control it. Please help.”

“At approximately 58,000 miles I discovered that the rear upper coil spring mounts on my 2020 Jeep Wrangler JL Unlimited Rubicon are separating from the frame. The factory welds attaching the upper coil perches to the frame rails have cracked and torn, and the mounts are no longer securely attached. I found this condition only incidentally, while inspecting the vehicle for a separate ongoing steering issue. The coil mount separation was not what I was looking for, and I would not have found it otherwise. These mounts carry the rear vehicle load. If one separates completely, the coil spring can unseat and the rear of the vehicle can drop on that corner, causing loss of ride height, brake line displacement, and loss of vehicle control. I consider this an imminent safety hazard and I have stopped driving the vehicle. The fracture surfaces are heavily rusted, indicating the welds failed a considerable time before I discovered the condition, most likely years earlier and within the warranty period. The vehicle was taken to Jeep dealers for service and inspection multiple times during that period, and no Jeep inspection ever identified or reported this failure.”

“I purchased this 2020 Jeep Wrangler from SunToyota car dealership in Holiday, FL on [XXX]. There have been several ongoing concerning safety issues with this vehicle and the car dealership over the past year since I purchased it. My vehicle has had immediate malfunctions and service visits upon purchase. On 12/31/24, the car went to the shop for broken visor (as is) as listed on service invoice- during this same visit I explained that turn signals lights were not functioning properly- was told that it was too much labor and they are aftermarket lights that the dealership cannot fix- dealership did not attempt to rectify the issue at this time. Broken visor/turn signal lights did not function properly upon purchase of the vehicle. In February, the car had what is known as the “death wobble” on major highways [XXX] and [XXX] in Florida, which was an extremely dangerous experience for all passengers in the vehicle. Invoice from 2/27/25 reflects suspension concern in regards to “death wobble” that was rectified, but again highly unsafe, and vehicle is beginning to shake again at high speeds as of December 2025. Invoice from 10/19/25 highlights the turn signal…”

“Suddenly at 82,000 miles, my 2020 Jeep Wrangler Sport S 4 door began shaking uncontrollably while I was driving. It was a terrifying experience. I took it to the mechanic and he replaced the steering damper. The uncontrollable shaking continued. The mechanic replaced the steering damper again. The shaking continues. I have had a wheel alignment and tires balanced. I am scared to drive the vehicle. I don't know what else to do, except trade it in?”

“The contact owns a 2020 Jeep Wrangler. The contact stated that while driving approximately 60 MPH, the vehicle experienced the "Death Wobble".

The local dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 60,000.”
