Type: Equipment (Suspension/Steering - Ball Joints) Manufacturer: Synergy MFG Incorrect/Used/Damaged Part Distributed By: UTM Distributing Co. dba Purely Power Sports Business Address: 125 W Crescentville Rd, Cincinnati, OH 45246 Retail Platform: Amazon Marketplace (Order # [XXX]) Tracking: The physical package contains an internal FedEx routing sticker (Label ID: [XXX]). Barcode: [XXX] Tracking #: [XXX] Processing Timestamp: [XXX] Fraudulent, defective items were introduced into shipping network at the FedEx facility in Arlington, Texas, establishing a direct physical origin point for the illicit supply chain investigation. Seller caused a printed a label pretending the parts were coming fresh from their own Ohio facility, but they had a third-party drop-shipper (or an unvetted liquidator) in Texas fulfill it using their account credentials. Seller is knowingly running a blind drop-shipping operation for safety-critical vehicle components without conducting any quality control, while actively deceiving the customer and the platform about where the inventory is physically located. Safety Risk and Defect: Deceptively altered, structurally failed, and mismatched safety-critical steering equipment introduced into interstate commerce. Amazon purchase made for a new, factory-sealed Synergy MFG Jeep JK Heavy Duty Adjustable Ball Joint Kit, Part Number 4127 (designated as Non-Knurled). The distributor, UTM Distributing Co. dba Purely Power Sports, caused to be shipped an open, unsealed damaged retail box where the authentic components had been removed. In their place, the distributor packaged used, damaged, and knurled upper ball joints. One substituted upper ball joints exhibits severe internal structural play and physical wobble straight out of the box. Amazon is processing a refund/instructed me to discard item. I will retain ball joints and all boxes/labels for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle experiences a severe, violent, and sudden side-to-side shaking of the front suspension and steering wheel (commonly known as "death wobble"). This dangerous oscillation typically occurs at highway speeds (approx. 55–70 mph) immediately after the vehicle strikes a normal highway bump, expansion joint, or pothole. Note: As a 4xe plug-in hybrid model, the vehicle carries substantially more curb weight than a standard internal combustion engine Wrangler due to the heavy battery pack and electric drivetrain components. This increased mass significantly magnifies the physical forces and wear placed on the front suspension and steering linkage during impact. Despite having less than 30,000 original miles and no history of accidents, the vehicle exhibits rapid component failure. Front-end steering and suspension components—including the inner drag link and tie rod ends—were previously replaced and aligned on March 17, 2026. However, the exact same dangerous steering instability and component wear reoccurred by September 17, 2026, indicating a persistent, underlying design or durability defect that standard parts replacement fails to resolve. When this failure occurs, vehicle control is severely compromised, requiring the driver to abruptly decelerate in active traffic to regain control of the steering mechanism. This poses an extreme safety hazard to the occupant and surrounding motorists, creating a high risk of a collision or loss of vehicle control.

Summary of Issue: The vehicle exhibited a repeatable dangerous steering oscillation after encountering road irregularities at speed. This occurred multiple times and is consistent with the known Wrangler “death wobble” condition for which a class action settlement exists on prior MY vehicles. Context: The wobble occurred several times during 2025, always on the highway. The violent oscillation (which seemed harmonic in nature) occurred when driving 65-70mph after running on a bumpy stretch of road (which basically describes most of Michigan right now). The only remedy was for the driver to immediately hit the warning lights, brake and slow down to around 20-25mph to reduce the oscillation, thereby regaining control. The Jeep service shop replaced all four shocks and the steering stabilizer, in addition to checking wheel alignment/balance etc. Additional Technical Context: I believe the Wrangler 4xe’s unique mass distribution may be contributing to the oscillation behavior, likely resulting in it acting differently to gas-powered Wranglers, The 4xe uses the same solid axle front suspension architecture as the gas powered Wrangler, but the hybrid model carries approximately 500–800 lbs of additional mass, much of it located low in the chassis and near the axle line. This added mass increases the effective unsprung and “near unsprung” inertia the suspension must control when the axle encounters a road disturbance. This higher inertia increases the energy transmitted into the track bar, tie rod ends, ball joints, and steering damper, reducing the system’s tolerance for even minor compliance, wear, or alignment deviation. It is my belief that the 4xe’s additional mass can amplify oscillation behavior after a bump, making the vehicle more susceptible to steering shimmy or ‘death wobble’ if any component is marginal.

Q1: The steering and front suspension system malfunctioned. The vehicle experiences a severe “death wobble,” violent and uncontrolled shaking/oscillation of the steering wheel and front end after hitting bumps or uneven pavement, especially at higher speeds. The suspected affected components may include the steering linkage, track bar, steering damper/stabilizer, ball joints, tie rods, control arms, bushings, alignment/caster, or other front suspension/steering components. Q2: The defect causes violent steering wheel and front-end shaking while driving, creating a loss of stable steering control. When the wobble occurs, the vehicle becomes difficult to control and I have to slow down significantly to regain control. This creates a serious risk of a crash, especially at highway speeds, in traffic, on curves, or if another driver is nearby. The first time it happened I was on the highway near two tractor trailers who recognized the issue and slow down for me too. The condition puts me, my passengers, other motorists, pedestrians, and anyone near the roadway at risk because the vehicle can suddenly become unstable after normal road bumps or pavement irregularities. Q3: The problem has been brought to an local mechanic 3 times for repair or diagnosis, but the issue has not been resolved. The vehicle continues to experience the same severe steering/front-end wobble after those repair attempts. As of this complaint, the issue has not yet been formally diagnosed or resolved by an authorized Jeep dealer. I am filing this complaint because the condition remains unresolved and I believe it is a serious safety defect. Q4: The vehicle has been inspected and repaired by an local mechanic on 3 occasions related to this issue. The Healy dealership fixed the last recall right before this. I called them on the way home from the dealership when it first happened. Q4: There were no warning lamps or dashboard message before the wobble occurred. Became more aggressive in Jan 2026.

This is a known death wobble problem of jeep which i got while driving on highway with my family and could have got into an accident if would not control vehicle that time. My dealer is charger me for this issue which is costing me around 1200 usd and they are going to change the parts 1. Damper, Steering, 2. Tie rod end-outer-right or left for both sides. This is something which should have been covered under recall as its a serious safety issue.

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 the federal safety agency 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.

Safety Concern – Steering Instability / Death Wobble – 2021 Jeep Wrangler Sahara To Whom It May Concern, I own a 2021 Jeep Wrangler Sahara with approximately 30,000 miles. I am writing to formally document and request a resolution for a recurring and severe steering instability commonly referred to as “death wobble.” The vehicle experiences violent front-end oscillation after encountering normal road conditions (e.g., highway speeds and minor road irregularities). This condition poses a significant safety risk to me, passengers, and other drivers. This issue has been widely documented in Jeep Wrangler models and addressed in various Technical Service Bulletins concerning steering dampers, ball joints, track bars, and front suspension components. Given the known history of this condition in Jeep vehicles, I am requesting: A full diagnostic inspection of all steering and suspension components. Confirmation of any applicable Technical Service Bulletins. Repair or replacement of defective components at no cost. Written documentation of findings and repairs. This vehicle has been properly maintained and has low mileage for its model year. A violent steering oscillation at highway speed is not normal wear and tear — it is a safety defect. If this issue cannot be resolved under warranty or goodwill assistance, I will pursue escalation through Stellantis Customer Care, the federal safety agency, and applicable consumer protection or lemon law provisions. I am requesting written confirmation of how this matter will be addressed. Sincerely, Cindy Rossbach 29872 Milby Drive Easton, MD 21601 410‑829‑2098 [email protected] VIN: 1C4HJXENOMW771106

For a few weeks prior to 12-21-2025, I've experienced minor Jeep "death wobble" (suspension issue) at highway speeds when encountering an irregularity (bump) in the road surface. On 12-21-2025, I experienced moderate Jeep "death wobble" at around 60 mph (several times). On a desert 2 lane highway, I was seriously in danger of running off the road to the right (crashing into rock faces bigger than the car) or running into oncoming traffic to the left. I was about an hour away from home and was able to reproduce the problem. I found that the issue was minimized if I kept it under 58 mph. Unfortunately, this motivated many drivers to dangerously pass me. The next day, I took it to the local off-road mechanic and they determined it was a worn tie-rod and recommended replacing the tie rod and installing/upgrading the steering stabilizer. From what I have read during my research is that those are band aid approaches to a more serious engineering/design issue with the Jeep Wrangler. I've further learned that Fiat-Chrysler (or the current owner) has continued to address the issue that has been problematic for decades. There are no recalls for my vehicle and the relevant TSBs I could find apply to older models (latest I saw was 2020 JL). However, it's clear the issue has not been resolved on my more current model (2021 Jeep Wrangler Rubicon JL). The vehicle is available for your inspection.
