NHTSA Complaint #11519666 — 2014 AUDI Q5

I recently discovered that my Q5 tubular rear subframe/crossmember (part # 8R0505235N) has rusted thru near a bushing that supports the rear transaxle. The rust thru area at the transaxle is about a foot long. This subframe supports the rear axle and all the rear suspension components. I brought my Q5 to the local Audi dealer and they took a video showing two areas on the subframe that have rusted thru, the bushing area supporting the transaxle and also an area supporting the left rear suspension. The dealership did not allow me to take the Q5 back and gave me a loaner vehicle to drive until the subframe can be replaced. The dealership contacted Audi North America and Audi agreed to pay 40% of the cost to replace the rear subframe. I think Audi should pay 100% as this is a serious safety issue. My Q5 has no other areas of corrosion except a slight amount of surface rust on the exhaust and is otherwise in excellent condition with only 50,444 miles. It has always been garaged since purchased new and has been in no accidents. The Audi service tech even complimented me on how clean my Q5 was at 10 years old. PS - How can I include an attachment of the video taken by the Audi dealership?
