NHTSA Complaint #11578220 — 2017 AUDI Q7

Rear coil spring on passenger side broke and became detached, wedging against lower control arm. Coil spring had no signs of other damage; seems to be defective metallurgy. While there was no immediate safety issue, a broken spring during driving could cause the operator to lose control. Additionally, unless you heard it break, there is no way to know that it is broken and under additional stress which is an ongoing safety concern. There was no warning that the spring would break or had broken. Others have reported hearing loud "pops" when the spring breaks. From online search, there seems to be a high number of Audi Q7's from 2017-2019 model years with this problem, but Audi dealers claim it is a 'normal wear' item and is not covered."
