2016 Audi Q5 Suspension Problems

1) Rear subframe supports differential, axels, suspension, brakes, wheels and tires 2) If rear suspension fails , above noted assemblies will fall out of the car 3) Yes, dealer and independent garage have inspected and condemned 4) Manufacturer is aware of the problem, 5) No warnings or messages appeared, 6/29/26 at garage for oil change, garage was installing a subframe for another q5 so he was familiar with the issue

My Q5 failed inspection due to a rusted subframe, so badly there is a huge hole in it. The dealership sent photos and notes to Audi but the dealership claims Audi denied my warranty claim (12 Year Corrosion Warranty) because it's not a body panel (the verbiage used in the warranty). However, Audi customer service told me it was because the dealership wrote a note that it was due to neglect. This is a safety defect that I was unaware of until now - I keep up with oil changes, have my car inspected every year and was never made aware of the problem until now so how would I be expected to know what was happening beneath my car. I've done lots of research online and this seems to be on the verge of becoming a common issue seen in 2010-2017 Q5s. So much so, there's a law firm investigating it like DiCello Levitt - could be a design flaw, there is a plastic covering known to trap moisture and debris. I also don't live in an area that gets much snow, some years we don't have any and I get monthly car washes.
