About a year ago both rear springs were broke and the dealership replaced them. about a month ago both front springs were broke and the dealership replaced them. all the replacements were done at my cost. i now have a rear right spring that has broke and will now have to have it replaced. in my over 50 years of driving different model cars and truck, i have never had spring failures such as this. i haven't hit any major pot holes that would cause this type of damage. this must be defective springs. the last time i was at the dealership having the front springs replaced they said this is common. it should not be common.
