2014 Audi Q5

2014 Audi rear subframe is rusted through. 92,000 Mi. My independent mechanic found the problem when performing suspension work. It has not been inspected by the dealer yet but will be soon. With the history of the subframe failures on these models and years, there is a danger to the public driving these vehicles on the road. Audi needs to fix these problems

The front subframe has experienced catastrophic failure due to severe and premature rust-through corrosion. Multiple holes have perforated the component, compromising the vehicle's structural integrity. The part is available for inspection upon request. The safety of my family and others was put at significant risk, as the subframe is the primary component that mounts the engine, suspension, and steering rack to the vehicle. A failure of the subframe while driving could cause a complete loss of steering control and the collapse of the front suspension, leading to a serious or fatal crash. The problem was independently reproduced and confirmed by both an independent service center and an authorized Audi dealership. Both establishments have deemed the vehicle unsafe to drive due to this specific issue. The manufacturer (Audi of America) has been made aware of the issue through their dealership network. They have acknowledged the defect by offering a "goodwill" repair to replace the subframe, confirming their awareness of this failure mode. However, the manufacturer has made this safety-critical repair contingent on the owner first paying for several thousand dollars of unrelated maintenance items, creating a financial barrier that prevents the safety fix from being implemented. There were no warning lamps, messages, or other symptoms prior to the failure's discovery. This is a silent failure that provides no warning to the driver. It was only discovered during a routine service visit when the vehicle was on a lift.

Under Recall 19N4, the electric coolant pump was replaced in July 2019 at 73,496 miles. That replacement pump failed prematurely in March 2025 at 109,628 miles — lasting only 36,132 miles. This was a safety-related recall part intended to fix a known defect with the original pump. Audi refused to provide goodwill reimbursement for this premature failure. I am reporting this to request further investigation and possible expanded remedy.

2014 Audi Q5 TDI with 115000 miles. Rear subframe inspected individually, by independent shop, and by Audi dealership. Found to have severe rust with perforation underneath where plastic debris covers are mounted. It is currently installed on vehicle at time of complaint. The failure of the subframe can disable the vehicle while driving, disconnect the axle and surrounding components, and cause an accident with one or more vehicles on the road. Audi has a 12 year/unlimited mileage warranty but claims it is not covered under warranty. Repair is quoted around ~$6000 including parts and labor.

I have noticed 2 times that my engine burn out oil very quick before the next predicted oil change and lead to safety risk of boosting engine while driving long distance if there is no auto one near. After speaking with one of the maintenance guy the last time I went for oil change at Jiffy live, He told me that there was a recall for the same problem with some other Audi models. How could we expect your help to address this safety concern with the manufacturer. This is very dangerous situation that you can’t neglect. Best regards,

I took my Audi Q5 TDI to the Garage for servicing and was told of heavy rusting on both sides of the rear subframe. The rusting is bad and can almost break the subframe It seems to be a known issue in Audi Q5 models, however, the dealership and Audi of America have refused to cover it as a manufacturing defect. The car has 88000 miles, and at this point, I think it may not be safe to drive. I am urging NTSB to review this issue and see if the issue can be resolved by the manufacturer at their cost.

The contact owns a 2014 Audi Q5. The contact stated that while driving at an undisclosed speed, the EPC (Electronic Power Control) warning light illuminated. The vehicle was taken to a dealer where it was determined that the vehicle was under recall; however, parts were not available. The vehicle was taken to the same dealer when parts became available and the vehicle as repaired; however, the failure reoccurred approximately 6 years after the recall repair. The manufacturer was notified of the failure. The failure mileage was unknown.

There is severe rust in the rear subframe. It's so bad that the rust has made holes right through the subframe - compromising its integrity. This is a serious safety issue as the subframe holds the suspension and wheels and could break at any point. This is not normal wear and tear. This is a manufacturer's defect and a major safety issue that needs to be addressed immediately.
