Not only do I have dry rot seperation between the treads on my tires (7456 miles), I have a broken rear spring, last coil. The car had 3800 dealer miles on it, and I have not hit any hard bumps. I am going to swap springs with something, this is nuts, WAY too softly sprung. My 87 civic has similar rear springs, hmmm............
Broken spring, rear

Well that is a new one one me. I have never heard of a broken coil spring, at least not in modern times.
I would highly doubt that the civic springs would be compatible. They may "fit" but surely the rate is not correct. Unless you like the "funny car look" that is.

Sorry to hear about your misfortune.
Although I haven't heard of any other broken springs in the automotive field, in industry they are fairly common. As some info:
Generally it is not a single "big bump" that will break a spring, so don't let the dealer try and say your driving was at fault. 99.9% of the spring failures I have examined were due to fatigue. Just the every-day spring motion, not any type of overload.
What happens is that the spring is made from steel "wire" (they call it wire even though it may be 1/2" in diameter) This wire is drawn through a die to shape it and then formed around a mandrel to give it the coil shape. Then it gets some heat treatment processes to make it springy.
In this forming and shaping process, the metal is still relatively soft and if the dies aren't alligned perfectly it can leave a small scratch in the metal, or if something happens to hit the spring and leave a dimple, or even some imperfection in the metal itself. Either way, this small imperfection is like scoring a sheet of glass...it will concentrate the day-to-day stress applied to the metal and make it fracture, even though the stress is well below what the metal could normally take in a "pristine" condition.
This is probably a couple paragraphs more than you wanted to know, but bottom line...unfortunate bad luck, should be replaced under warranty, no fault of you or your driving.
Good Luck

springs part two
The dealer will replace spring, and I am aware of the stress riser situation, common also when working with aircraft aluminum. I am intrested in higher rate springs, the civic ones no doubt would need cut to give proper height, but the rate increase is desireable. I also have Eibach sending me tech details on it's custom springs. As a frustrated aircraft mechanic/engineer I know how much better our car could be in rear spring rate. If I find something, I will let you know. I also am looking into air shock replacements for same purpose, a small but needed progressive increase in spring rate. Short travel suspensions are more critical for proper rates.
