Rear Suspension cross- member. Extensive corrosion hidden behind stone guard trapping dirt and moisture. I would not have known the rust was there if the stone guard had not come apart from the cross member I cannot trust the safety of this vehicle until it is repaired Audi requires a dealer inspection at the cost of the consumer. Audi Suspension cross member components are the same for many models. The Allroad should be included in the class action lawsuit.
An Audi dealer installed 245/40R18 93H tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40R18 97H. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect vehicle stability, heat buildup, braking, steering/cornering, suspension loading, and tire failure/blowout risk. After discovering the mismatch, the concern was reported to the dealer and Audi, but...

the dealer stated the 93H tires were acceptable rather than providing a safety-based correction. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the vehicle may have been operated with under-rated tires and because the issue can affect handling, braking, tire durability, suspension/wheel components, and safe vehicle control. Tire/repair-order records, door-jamb placard evidence, load-index comparison evidence, and dealer communications are available.
Since I purchase my vehicle I have had to continuously replace my tires on the front. Going through my carfax acct I came across some recalls that showed up that I had no idea of the car may had which was prior to purchase from the dealers. I would think that these issues were fixed prior to reselling. I recently had to pull over on the freeway due to the tire making noises then realized that the tire wear was uneven again but this time shredded apart. I could feel metal poking out which the tires hadn't been on...

for long. The loss pressure warning light went off. I later found the missing tire that has came off wrapped around the rotor which the tire shop near me hadn't seen while replacing with new tires again. The wear on the brake pads were off as well as the rotors which I also ended up having to replace just recently. I've made an appointment with a dealer which is out of my way to hopefully have this resolved but needed to make a report of this safety issue.
DESCRIPTION OF THE SAFETY DEFECT On February 24, 2026, an Audi-certified technician at Audi of Milwaukee discovered substantial rust perforation of the rear subframe on my 2014 Audi A4 Allroad (Repair Order #[[redacted]]). The technician documented the condition as follows: "INSPECTED REAR SUBFRAME CORROSION. RECOMMEND TO REPLACE REAR SUBFRAME AND RELATED PARTS." The quoted cost to replace the rear subframe, control arms, and related components is $11,583.00. The vehicle was otherwise inspected as being in...

excellent condition with no body panel corrosion. Root Cause: Manufacturer-Installed Plastic Shield Design Defect (B8/B8.5 and B9 Platforms) The corrosion is caused by a design defect present on the Audi B8/B8.5 and B9 platforms: plastic aerodynamic shields are installed by the manufacturer on both sides of the rear subframe. These plastic shields trap road salt, water, and debris directly against the bare steel subframe, preventing it from draining or drying. Even vehicle owners who regularly wash the undercarriage - as I did - cannot prevent salt accumulation behind these shields. This is not general road salt exposure. The plastic covers are an Audi-designed component that actively concentrates corrosive materials against the subframe. The corrosion therefore originates from a manufacturer design decision, not from owner neglect or normal environmental exposure. III. SAFETY RISK The rear subframe is a primary structural and suspension component. It mounts the rear suspension, differential, and drivetrain to the vehicle. Rust perforation of this component poses the following safety risks: •Structural failure of the subframe while driving, potentially causing sudden loss of vehicle control •Collapse of rear suspension leading to loss of steering stability •Separation of the rear drivetrain or differential from the vehicle under load •Increased risk of catastrophic failure when towing, carrying passengers, or during emergency maneuvers •No visible warning to the drive INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Excessive abnormal corrosion of rear subframe.
Audi installed plastic covers over sections of the subframe on allroad, Q5 models, and other models. These covers held in water and salt causing severe rusting and corrosion of the rear subframe. Subframes of these models are seriously structurally compromised and also hidden from view due to these plastic covers. It's seems Audi is repairing some under their 12 year rust/corrosion/penetration warranty, but the response varies based on dealership (some people are being told this warranty only applies to body...

panels, others are told that they are ineligible due to not regularly servicing their vehicles at the dealer). Many others are past the warranty timeline. This issue requires immediate attention and a full recall. Thanks [[redacted]] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Fortunately no catastrophic failure or accident occurred. At about 40,000k miles the rear spring mounts are significantly corroded and need replacing. This appears to be a galvanic reaction that occurs due to a design flaw which shortens the life of the critical mounts. I'm told one could fail imminently and the other is headed that way. Had this failed in use the damage would be significant and caused an accident. The service advisor said that Audi is aware of the short lifespan and has an improved version that will be used in the repair. I have a video of one of the mounts and will request the parts when repaired.

According to TSB 401548, car dealership/manufacture will not provide extended warranty to repair premature wheel bearing due to vehicle VIN not in their system as an affected vehicle. The 2016 A4 has premature wheel bearing as described in the TSB 401548. Covered vehicles are 2016 Audi A4. Faulty wheel bearing may result in loss of control of vehicle and will not pass Pennsylvania State Inspection. This is a safety defect and a wheel bearing should not fail with only 63,000 miles on the vehicle. Please assist. Thank you.

The coil springs broke on this vehicle on 2 separate occasions. The left front coil spring broke while it was being driven by my husband on 7/24/19. The left rear coil spring broke while I was turning out of my driveway on 4/21/20. The vehicle has over 81,000 miles, but is in very good condition. I am careful to avoid pot holes while driving, so I don't believe the cause is due to my driving habits. The photo I have provided shows the break is not due to rust. This has never happened with any vehicle that I...

have driven in the 50+ years I have been driving . My understanding is that a broken coil spring is very dangerous and can cause an accident particularly if it punctures a tire while driving. My suspicion is that the coil springs are defective given that the breaks occurred with 2 different coil springs. Since this has happened twice, I chose to replace all the coil springs in the car because I fear for my safety. I understand that volkswagon, of which audi is a part of, recalled over 56,000 vehicles last year due to defective coil springs. However, I cannot find any information regarding a recall for audi coil springs.
I bought this 2014 audi a4 used in 1/2019. The car seems to have major steering and suspension issues. Although I've had it checked by professionals multiple times,?Aligned multiple times, and tires rebalanced multiple, no one can determine the problem. It's hard to control the car on freeways. Sometimes it seems impossible to keep the car in a straight line. The car wanders all over the freeway. It's very dangerous. Unfortunately I'm unable to sue using the lemon law because I bought it used.
