Here is more information on what your coil springs do for your vehicle and what causes them to fail. Coil springs have long been used to stabilize vehicles around corners and over bumps and dips.
Do coil springs go bad while driving?
However, coil springs rarely go bad while driving under normal conditions. On average, a coil spring will wear out after about ten years of use. With that said, many cars will require a suspension coil replacement at some time, especially if you want an upgrade. With high-performance springs, the ride can be even smoother and more enjoyable.
What causes coil springs to break?
Most springs fail due to fatigue, meaning they have sustained many compression-extension cycles, and the metal becomes brittle and breaks. If the amplitude of these cycles is large, the fatiguing process is accelerated. Cars with continually overloaded trunks are candidates for early spring failure.

What is uneven tire wear?from mechanicbase.com
Uneven Tire Wear. The suspension system ensures that the wheels and tires remain balanced while traveling down the road. As the tires rotate, they should receive equal amounts of wear for a safe drive. When the coil springs go bad, the wheel alignment geometry is changing, leading to excessive wear on one side.
Why do coil springs work?from mechanicbase.com

Why do coil springs need plastic coating?from startrescue.co.uk
Coating damage and corrosion. Coil springs are covered in a flexible plastic coating to help protect the metal from corrosion. However, over time, with constant compression and being hit by stones from the road, this coating can get damaged, allowing rust to form on the coil. Once this happens, the coil can weaken and potentially break.
