Owners of the 2014 Kia Soul describe a pattern of steering system failures ranging from loss of control to component separation. The most frequent complaint involves the steering pinion gear or gear assembly separating from the steering shaft, causing the steering wheel to turn freely while the wheels remain straight. Multiple owners report sudden steering failure while turning at low speeds (15–40 mph), veering into trees, curbs, and oncoming traffic. Several crashes resulted in roll-overs and injuries.
Steering clunking and popping noises are widespread, often persisting or recurring after recall repairs. One owner reported complete failure just four days after a recall repair, and another experienced steering failure 16 months after the recall work was completed.
Power steering failure appears as an additional issue—the system stops providing assist, making the wheel unmovable or requiring extreme force to turn. At least one case involved a fractured rack-and-pinion assembly. A few owners also report steering wheel fractures or wheels snapping off entirely.
Dealers often delayed or were unable to perform recall repairs due to parts unavailability. Some owners report being told to continue driving vehicles with known steering defects while waiting for parts or service appointments. One owner's vehicle was held for three months at a dealership for post-recall diagnostics after a crash.
Failure modes owners describe
Steering gear assembly separation / pinion gear separation
The steering pinion gear or steering gear assembly separates or comes loose from the steering shaft, causing complete or near-complete loss of steering control. In some cases the steering wheel turns but the wheels do not respond.
When: Typically between 3,874 and 60,000 miles; some reported early on (26,000 miles), others later in vehicle life
Symptoms owners cite: Steering wheel turns but wheels do not turn; Complete loss of steering control; Sudden steering failure while turning; Steering wheel becomes very loose; Vehicle veers off road or into traffic when steering fails
Repairs/costs cited: Rack and pinion replacement; pinion gear plug repair procedure; spline separation from shaft identified in some cases
Recalls/TSBs owners mention: NHTSA Campaign 14V332000 (Steering Gear Assembly), 15V736000 (Steering), 17V608000 (Steering); parts availability was delayed in many cases; some dealers unable to perform repair; repair does not always permanently resolve issue
Steering clunk or clunking noise from steering coupler/column
Metallic clunking, popping, or grinding noises emanate from the steering system when turning. In some cases the noise originates from a rubber steering coupler that deteriorates over time. Issues persist or recur even after recall repairs.
When: Can occur early in ownership or develop progressively; some owners report continued issues 16 months after recall repair
Symptoms owners cite: Clunking or clucking noise when turning steering wheel; Popping noise from steering system; Grinding noise when turning; Noise especially pronounced on first drive of the day; Noise can be felt through steering wheel
Repairs/costs cited: Steering column bolt found missing in one case; steering column replacement quoted out of warranty; coupler/coupling deterioration mentioned
Recalls/TSBs owners mention: Steering coupler recall 15V736000; repairs performed under warranty but issue recurs; dealers sometimes unable to reproduce noise or claim it is normal operation
Power steering failure / loss of power steering
Power steering system stops functioning, requiring excessive force to turn the steering wheel or rendering the wheel unmovable. Failures can occur without warning and may coincide with rack-and-pinion fracture.
When: Between 25,000 and 51,000 miles reported
Symptoms owners cite: Power steering stops working suddenly; Steering wheel becomes very stiff and difficult to turn; No power assist when turning wheel; Complete inability to steer in some cases; Failure occurs without warning while driving
Repairs/costs cited: Rack and pinion fracture identified and replaced in cases diagnosed; some owners experienced stiffness in turning prior to complete failure
Recalls/TSBs owners mention: Not explicitly mentioned for this failure mode in the narratives
Steering wheel locking or seizing
Steering wheel suddenly locks or becomes immovable during normal driving, preventing the driver from turning the wheels. In some cases steering wheel seizes completely.
When: Reported at 26,000 and 31,000 miles
Symptoms owners cite: Steering wheel suddenly locks or seizes; Steering wheel becomes impossible to turn; Loss of all steering control; Vehicle veers or crashes due to locked steering; Clunking noise sometimes precedes locking
Repairs/costs cited: In one case, drive shaft hub nut replacement had been performed prior to failure; unclear if related
Recalls/TSBs owners mention: NHTSA recall 14V332000 mentioned; manufacturer not notified in some cases
Steering wheel fracture / steering wheel structural failure
Steering wheel cracks or fractures, sometimes complete failure where the wheel snaps off in the driver's hands during operation. In one case steering wheel popped and became loose.
When: One case at 11,808 miles; another at low mileage shortly after recall repair
Symptoms owners cite: Steering wheel fractures or cracks; Steering wheel snaps off completely; Sudden looseness in steering wheel; Steering wheel becomes unable to control vehicle after fracture
Repairs/costs cited: Steering wheel replaced; cost not specified
Recalls/TSBs owners mention: Not mentioned in narratives for this specific failure
Steering system knocking/knocking noise from left side
Loud knocking or clicking noise from lower left side of engine/steering area during driving. Mechanics unable to identify origin in some cases.
When: One case reported at approximately 30 MPH while driving
Symptoms owners cite: Loud knocking or clicking sound from lower left area; No error codes preceding the noise; Noise appears during normal driving
Repairs/costs cited: Mechanic unable to determine cause of problem
Recalls/TSBs owners mention: Not mentioned
Steering wheel unable to turn / wheels unresponsive to steering input
Steering wheel can be turned (sometimes freely) but the front wheels do not respond, leaving the driver unable to steer the vehicle.
When: Multiple cases between 26,000 and 60,000 miles
Symptoms owners cite: Steering wheel turns but wheels remain straight; Wheels do not respond to steering wheel input; Steering wheel can turn 360 degrees with no effect on wheels; Clicking noise when steering wheel is turned; Complete steering disconnection between wheel and axles
Repairs/costs cited: Spline separation from shaft identified in at least one case; rack and pinion inspection required
Recalls/TSBs owners mention: NHTSA campaigns 14V332000 and 15V736000 mentioned; no specific manufacturer response detailed
Steering stiffness / excessive steering effort required
Steering wheel becomes stiff and requires excessive force to turn, making normal driving difficult. Sometimes precedes complete steering failure.
When: Reported at 38,000 and 41,000 miles in some cases; can be progressive
Symptoms owners cite: Steering wheel requires excessive force to turn; Steering becomes progressively worse over time; Difficulty turning at slow speeds; Stiffness especially noted on turns; Vehicle veers when steering effort is insufficient
Repairs/costs cited: Not explicitly addressed in repairs; steering column replacement mentioned as potential fix out of warranty
Recalls/TSBs owners mention: Multiple dealer visits in some cases; some dealers stated vehicle operating as designed
Front axle nut loose / wheel assembly instability
Front drive axle nut loosens on its own without any mechanical work performed in that area, causing severe vibration and nearly causing wheel assembly to separate.
When: One case at 2/01/2017
Symptoms owners cite: Left front wheel shakes violently; Vibration in vehicle caused by loose wheel assembly; Nearly caused wheel to come off vehicle; No prior work performed in that area
Repairs/costs cited: Torque checked and found to be significantly below factory spec (170-198 ft-lbs); nut has no locking mechanism to prevent back-out
Recalls/TSBs owners mention: Not mentioned in narrative
