Open the full vehicle complaint log (all categories)Audi installed plastic covers over sections of the subframe on allroad, Q5 models, and other models. These covers held in water and salt causing severe rusting and corrosion of the rear subframe. Subframes of these models are seriously structurally compromised and also hidden from view due to these plastic covers. It’s seems Audi is repairing some under their 12 year rust/corrosion/penetration warranty, but the response varies based on dealership (some people are being told this warranty only applies to body panels, others are told that they are ineligible due to not regularly servicing their vehicles at the dealer). Many others are past the warranty timeline. This issue requires immediate attention and a full recall.

Excessive abnormal corrosion of rear subframe.
REAR COIL OF SUSPENSION BROKE ON DRIVERS SIDE, 49800 MILES ON THE CAR. INDEPENDENT SHOP AND DEALER CLAIM IT IS COMMON AND I FIND IT WEIRD FOR A PART TO FAIL (IT SNAPPED) AT SUCH LOW MILEAGE. I WAS NOT AWARE OF ANY HARD HITS OR POT HOLES THAT I HAD HIT OUTSIDE OF NORMAL DRIVING. THE PART WAS A HAZARD AS IT WAS LOOSE BOUNCING INSIDE OF SUSPENSION AND MADE A NOISE. NO SENORS WENT OFF DUE TO THE FAILED PART.
