Symptoms

Loud 'twang' or bang when turning the steering wheel at low speeds
Car sits noticeably lower on one side
Grating noise over bumps

Root Cause

The protective coating on the steel spring chips from stone impacts. Salt water corrodes the exposed steel, weakening the spring until it fractures under load.

How To Fix

Visually inspect all four springs for fractures at the very bottom coil.
Always replace coil springs in pairs across an axle to maintain handling balance.
Cost: £150-300 per pair at an independent garage.

Other Faults on This Variant

Air Conditioning Condenser Leak (Stone Damage)

Minor

2010-201540,000–120,000 miles£250–£450

The air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.

Front Anti-Roll Bar Drop Link Wear

Minor

2010-201530,000–80,000 miles£60–£120

The front anti-roll bar drop links wear out on heavily potholed UK roads, causing an annoying knocking sound at low speeds.

Transfer Case Spline Failure (AWD models)

Critical

2010-201560,000–120,000 miles£1500–£2500

On AWD models of the ix35 and Sportage, the splines connecting the gearbox to the transfer case completely shear off, leaving the car as Front-Wheel Drive only.
