general problems of the 2011 Audi Q5

1) the rear structural subframe (crossmember) has completely rotted, perforated, and failed due to severe corrosion. The factory-installed plastic underbody rock shields trapped road salt and water, causing the frame to rust from the inside out. The corrosion has spread, completely fusing and compromising the rear suspension mounting points and the rear differential brackets. The vehicle is fully available for physical inspection upon request. 2) my safety and the safety of others on the road was severely put at risk because the structural integrity of the rear suspension is completely compromised. The rusted metal anchors could snap under driving loads, causing a catastrophic rear suspension collapse, loss of vehicle control, or a high-speed wheel separation on the highway. 3) yes. The structural failure was independently confirmed by two independent automotive service centers and an authorized Audi dealership service center (Audi dallas). 4) yes. An authorized Audi dealership representing the manufacturer physically inspected the vehicle on the lift during a goodwill evaluation. They confirmed the extensive structural damage and issued an official diagnostic repair quote of $20,873. 78 to completely rebuild the failed rear subframe, effectively totaling the vehicle. 5) no. There were absolutely no dashboard warning lamps, electronic messages, or obvious driving symptoms prior to the inspection. Because the factory plastic underbody shields completely hidden the metal frame from view, the structural rot developed entirely out of sight until the vehicle was placed on a mechanical lift.

During an inspection of my 2011 Audi Q5 at Audi burlington, severe corrosion was discovered on the rear subframe, which supports rear suspension components. The corrosion was substantially worse than normal surface rust and may compromise the structural integrity of the subframe and suspension mounting points. The condition was not readily visible during ordinary vehicle use because portions of the subframe are covered. The vehicle has been operated in the northeastern united states, where road salt is used. I was advised that the rear subframe requires replacement at an estimated cost of approximately $5,884. I am concerned that continued deterioration could result in separation or movement of a suspension mounting point and a loss of vehicle control. Audi has not issued a recall or offered to cover the repair. I am aware of similar reports involving Audi Q5 rear subframe corrosion and request that NHTSA investigate whether the design permits moisture, salt and debris to remain against the subframe and cause premature structural corrosion.

Rear subframe rust causing car to fail state inspection. This vehicle has been maintained well and always parked in garage. The rear subframe rusted most, then front subframe. This is a common compliant among Audi forum users.
