The rear sub frame has completely rusted through, on both driver and passenger sides. This makes the vehicle extremely unsafe to drive. It is a 2014 Q5 with 160k miles. There is a hole on the bottom of the frame on both sides due to a poorly designed cover that traps salt and other road debris leading to premature failure.
This vintage 2014 Audi a5 has a well known serious rust perforation issue with the rear subframe. The corrosion / rust through of two major holes, approx 3 inches in diameter, causing structural failure of the sub frame. This is a major saftey concern with these cars from model year 2009 thru 2017. The only remedy is replacement of the sub frame under Audi's 12 year rust perforation warranty or good will.
Severe corrosion of the rear subframe crossmember on a 2014 Audi Q5 premium plus, purchased with 65,464 miles. Two independent inspections in south carolina confirmed structural failure. Audi of greenville, an authorized Audi dealership, marked the condition as very dangerous on the service invoice and quoted $4,711. 52 for subframe replacement. They were unable to perform a wheel alignment due to the severity of the corrosion. Yoder's automotive in westminster, SC independently confirmed the subframe was rusted beyond repair on both sides. Fist-sized holes have corroded through the structural metal on both sides of the subframe. The vehicle has plastic stone guard covers bolted over the subframe from the factory. These covers trapped road salt and moisture against unpainted mild steel, accelerating concealed corrosion that was invisible until the covers were removed during inspection. The vehicle is undriveable and has not been driven since the defect was discovered in approximately March 2026. This defect pattern is documented in at least 16 prior NHTSA complaints for Audi Q5 models spanning model years 2010 through 2018. Audi has revised the subframe part number at least five times (8r0505235f through 8r0505235n) but has issued zero recalls and zero consumer notifications.
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.
Took my vehicle in for an alignment, was told by my local Audi dealer the rear subframe has rotted through and will need to be replaced. I asked how could this happen on a vehicle under 10 years? they said they see a lot of Q5's with similar rust issues due to a design flaw where a plastic protective cover cups and holds water directly on the structural part of the vehicle. They quoted me $8,000 to fix and offered no assistance on the price. Many, many others in forums and social media pages have the same issue and are forced to pay out of pocket for this issue caused by Audi.
Universal joints rubbing and need to be replaced. Common problem apparently and no recall by Audi. Paying over $800 for this repair. Power steering impaired.
