Front coil spring failure is the dominant complaint in this cluster. Breaks occur at low speeds—reversing from driveways, pulling away from a gas station, even while parked—with mileages ranging from 38,000 to 75,000 miles and beyond. When a spring fractures, the broken pieces puncture the tire, sometimes shredding it or causing all four tires to flatten simultaneously. Owners describe a loud bang or boom as the front end suddenly drops. One owner's spring broke twice; another's broke after five years of ownership with visible rust and corrosion on the fractured pieces.
Hyundai issued recall campaign 124 (NHTSA 14V435000) for coil spring inspection and replacement, but one owner reported the replacement parts were on backorder for one to four weeks or longer. When Hyundai did reimburse a repair bill of $2,028.91, they paid only $949.03, leaving the owner short thousands of dollars.
A separate complaint describes a broken lower control arm that fractured in half, causing hard clunking in the front wheel—a failure the owner noted could have been catastrophic if it had broken completely while driving.
One early-ownership complaint documents a persistent front-end vibration described as feeling like "an egg in the tire," which multiple mechanics and tire shops could not diagnose or fix, and which worsened over time.
Failure modes owners describe
Front coil spring fracture/breakage
Front coil springs break or fracture, often with rust and corrosion present. Breaks occur at low speeds (parking, reversing, pulling away from gas station) and higher mileages. Broken spring fragments puncture the tire, sometimes shredding it. In one case, the spring dug into the tire 'like a knife.' Failures cascade—one owner's spring broke twice.
When: 38,000 miles to 75,000+ miles; some failures occur years into ownership (5+ years)
Symptoms owners cite: Loud bang or boom from front end; Front end suddenly lowers to ground; Hard clunking in driver-side front wheel; Tire punctured or completely flat; Vehicle will not move after startup; Multiple tires flat simultaneously
Repairs/costs cited: Dealer replacement of coil spring. One owner paid $2,028.91 out-of-pocket repair; Hyundai recall reimbursed only $949.03. Parts availability issue: recall parts on backorder one week to one month or more.
Recalls/TSBs owners mention: Hyundai recall campaign 124 (also referenced as NHTSA 14V435000) for inspection and replacement of front coil springs due to corrosion. One owner was told by manufacturer nothing could be done to assist.
Lower control arm breakage
Driver-side lower control arm breaks in half. Owner noted that if it had broken completely while driving, the wheel could have come off and the vehicle could have flipped.
When: Not specified
Symptoms owners cite: Hard clunking in driver-side front wheel; Lower control arm broken in half
Repairs/costs cited: Part requires removal of tire and inspection to diagnose.
Undiagnosed front-end vibration/roughness
Persistent vibration or rough sensation described as feeling 'like an egg in the left front tire.' Problem persists after new tires installed. Multiple mechanics unable to find root cause. Condition worsens over time.
When: Early in ownership (a few months after purchase)
Symptoms owners cite: Rough ride sensation like 'an egg in the tire'; Left front area feels rough; Problem worsens over time
Repairs/costs cited: New tires purchased; no mechanical issue found by two mechanics or tire shops.
