WOW 3 broken springs?!. Is this a common thing?. If I end up in the same situation, I will do a "Junkyard parts special" for sure.
To be fair, I live in Minnesota, and I drive it year round. The salt can be brutal. After the junkyard spring broke 3 months in, I ended up buying new strut assemblies from rockauto.com this past march along with new control arms, and inner and outer tie rods. The bushings were shot, the spring was broken, and the toe adjustments were seized solid. Next up is a complete refresh on the rear since the bushings back there just tore a month or two ago.
My car is 11 years old, and most of the parts I am replacing are likely original, plus I drive spiritedly and in all types of conditions. So it may or may not be common, but that is what happened to mine.
