Our car is just 5 years old, and has had no problems at all so far, but two weeks ago something weird suddenly happened. When you made a sharp turn, upwards of 90 degrees right or left, there was a sound as if a coil was being stretched, until it abrubtly went "goioinggg!" so loud that bystanders would dive for cover. Apart from this "cosmetic problem", nothing seemed to be obviously malfunctioning apart from the steering wheel pulling to the right. It didn't match any kind of car problem that I had heard about before, and nobody I talked to had any idea (apart from the usual helpful but wrong random guesses).
Yesterday, I got it back from the mechanic. The reason for the ruckus: a snapped suspension spring. (I didn't know this could happen.) Total cost: about $500 - they had to change on both sides. Sigh.
