A Jeep "death wobble" class action lawsuit alleges defective solid front axles and damping systems cause violent vibrations of the steering wheels while driving highway speeds.
The Jeep class action lawsuit includes current and former owners of 2018-2020 Jeep Wrangler and 2020 Jeep Gladiator SUVs in the U.S.
According to the lawsuit, the “death wobble” is the "seemingly uncontrollable side-to-side shaking of a Jeep’s front-end steering components and---by extension---its steering wheel, presenting a serious safety hazard to the driver of the Jeep Vehicle and surrounding drivers."
California plaintiff Melinda Martinez owns a 2018 Jeep Wrangler she purchased new in March 2019, but the Jeep allegedly experienced the death wobble multiple times.
According to the lawsuit, she was traveling in the Jeep with her child when the Wrangler steering wheel allegedly started to shake violently, making the plaintiff believe she was going to lose control of the SUV.
Martinez says she took the Wrangler to the dealership in January 2020, but an employee allegedly "laughed and explained that the issue is known as the 'death shake' and 'it happens.'"
However, her Jeep received the new steering dampers based on a customer satisfaction program, but the plaintiff says her Wrangler still suffers from the "death wobble."
Vehicles with solid front axles don't absorb bumps and vibrations as well as vehicles with independent suspensions because solid axles are better for off-road use; therefore dampers/stabilizers are installed to reduce vibrations during highway driving.
However, the class action lawsuit alleges, the bumps and vibrations cause premature loosening of the tie rods, control arms, track bars, ball joints and stabilizers.
The so-called death wobble typically occurs when traveling more than 45 mph, and while Fiat Chrysler (FCA) denies there are safety hazards, the class action alleges serious safety concerns exist.
Chrysler's customer satisfaction program mandates replacement of the steering dampers, but the lawsuit alleges multiple suspension components should be replaced. The plaintiff says those components include the ball joints, upper inner tie rods, dampers and track bars.
According to the class action lawsuit, by claiming the vibration isn't a safety issue and something that can occur to any vehicle with a solid front axle, Chrysler allegedly can continue making failed repairs until the warranties expire.
Fiat Chrysler has known about the steering wheel vibrations since 2010, when the automaker created technical service bulletin (TSB 02-003-10), instructing dealer technicians to replace the steering dampers and damper brackets if 2007-2009 Jeep Wrangler owners complained about vibrations from rough road surfaces.
In November 2019, Chrysler added the 2020 Jeep Wrangler and 2020 Jeep Gladiator in TSB 19-002-19 related to “Shimmy In The Steering Wheel After Hitting An Irregularity On The Road Surface.”
Dealerships were told, “(t)he customer may notice a shimmy in the steering wheel after hitting an irregularity on the road surface such as an expansion joint, pothole or bump.”
