2013 Audi Q5

There is considerable rust to the point that the subframe has been structurally compromised. I also contacted Audi USA regarding this issue, but they advised that they could not provide any assistance and closed my case. I was instructed to have the vehicle inspected and see what the dealer could do. I have videos and photos documenting the compromised subframe which many Audi Q5 owners have been complaining about.... There are holes approximately the size of a tennis ball.

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.

When at highway speed, the vehicle veered hard to the left without any driver input, causing the car to cross several lanes of traffic and hit a concrete divider at ~65mph. The driver fractured her back, and one of three children in the car experienced injury. The vehicle was declared a total loss by insurance. The driver (my wife) indicated that a similar incident happened at low speed in a parking lot, but it resolved after shut down and restart of the engine. It is my understanding that the vehicle is currently either at or on the way to a Copart lot.

I was doing maintenance on car. Had new tires and alignment done. The alignment tech found rotted out rear sub-frame underneath plastic covers. Said that it was unsafe to drive. Had it fixed there. Mechanic had another Q5 on rack, he said it had exact same problem. Tried to find used parts, ALL had rot through the frame. Found a part in Texas that was clean and bought it to replace. Asked Audi USA to reimburse me for the cost as they have a supposed 12 yr rust through warranty. They told me no because it only applies to body parts and that I didn't get it done at an audi dealer. The plastic cover is the issue as it keeps the moisture locked into the part. Audi A6s have the same frame but no cover and they don't rot. This is a dangerous situation and Audi is looking the other way.

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".

Car was telling me to add 1 qt of oil about every 1500-2000 miles, even after a recent oil change. So I took it to the place I purchased the car from and they replaced the timing chain gasket thing. About a week later the same issue came back. So I took it to Audi to have the same thing replaced. And about a month later the issue came back. Took it back to Audi and they said now the Engine speed sensor seal is leaking oil. I’ve did some research and I’ve found that there is a manufacturing engine defect that causes this reoccurring issue and most Q5 owners have stopped spending money on repairs and just tops off the oil when asked.

The vehicle oil level low light comes on every 600 miles (excessive oil consumption). I purchased the vehicle in July 2021, and in 2 weeks I had an oil-level light. I called Audi regarding the condition, they talked with the dealership regarding the issue and came back in 2 weeks and stated that the recall was up to 2011. I would like Audi to pay to repair my vehicle, because is a known problem which should have been resolved. Oil Change on 1/12/24; had to put oil in on 2/20/24
