Issue only presents itself when plastic covers are removed, revealing rust/corrosion and lost material, and a risk of the subframe to split resulting in lost of vehicle control on the road. This was found as a preventative action due to reports from other car owners and is confirmed by Audi Dealers as a common issue. Labor and parts estimate around $6000 (including $2000 in parts)”

This is a manufacturer's defect and a major safety issue that needs to be addressed immediately.”
