Body problems of the 2013 Audi Q5

Took vehicle in for state safety inspection. Found heavy rust on subframe nearly all the way through. Was told if it gets any worse it will not pass inspection next time. Apparently there are plastic rock shields on subframe that trap water causing it to rust. Took it to dealer and they want to charge close to $4000 to replace. This seems like an engineering defect. The vehicle is kept in a garage and doesn’t have any other rust on it.

The rear subframe has plastic "stone guards" to protect the frame from being damaged in off-road conditions. Where these stone guards are attached, the subframe has rotted/rusted large holes. Water and salt from winter seasons can get trapped behind these guards. A subframe on a vehicle at this age should not have complete holes rotted through. Let alone a vehicle brand such as Audi, known for quality. The rear subframe connects the rear suspension and awd drivetrain to the unibody of the vehicle. This is a major safety concern. It has not been inspected by the manufacturer; my Audi dealer denied this could happen. I am part of a few Audi groups/forums with others facing the same issues, and Audi replacing the subframe under the corrosion warranty. This is a widespread issue amongst the forums. There are no warnings or symptoms as of yet. I noticed the holes 3/17/24. The vehicle has been somewhat sufficient to operate. I just don't want to be traveling down the road with my family in the vehicle if the subframe collapses. I am afraid to fully remove the stone guards as others on the forums claimed that Audi would do nothing for them after removing the guards. Being that they are "protection".

Panoramic sunroof has been making noise since I purchased the vehicle. Dealer has attempted to remedy the issue 5-6 times with no resolution. It's noisier during the winter than during the summer. Noise is heard anywhere from 20 to 50 mph on smooth or bumpy road makes no difference.

Chronic sunroof rattling. While driving at various speeds, panoramic sunroof rattles consistently while closed. Dealership has not been able to fix after 4 attempts. Vehicle is under warranty. Dealership is aware of issue but is unaware of a resolution.

The contact owns a 2013 Audi Q5. The contact stated that while driving at various speeds, she heard a loud noise coming from the sun roof. The contact mentioned that the failure occurred several times and every time the roof was close. The vehicle was taken to the dealer. The technician was unable to duplicate the failure. The manufacturer was not made aware of the failure. The vehicle was not repaired. The VIN was not available. The failure mileage was 1,500 and the current mileage was 5,500.
