SERVICE BRAKES,ENGINE,VISIBILITY/WIPER

I am reporting severe vehicle safety defects and merchant safety non-compliance regarding a 2014 Audi A4. The vehicle was financed with severe, undisclosed engine defects, specifically extreme oil consumption and catastrophic coolant leaks. When I requested warranty repairs, a dealership representative named Stephen explicitly instructed me in writing via text message to intentionally operate the vehicle with active oil and coolant failures until the engine suffered a total mechanical blowout. Relying on this directive, I operated the vehicle, resulting in a sudden engine seizure inside a high-traffic 4-way light intersection placing my safety in immediate jeopardy. Additionally, the dealership lied stating the service brakes were brand new, but they were dangerously worn down and squeaking upon delivery, failing basic intake safety standards. I possess full text transcripts verifying these inspection lies and bad-faith directives.

SUSPENSION

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 #[XXX]). 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)

ENGINE

The timing chain and tensioner in my 2014 Audi A4 Quattro (VIN: [XXX] ) failed without warning, causing the engine to suddenly stall and become inoperable while in motion. This presented a serious safety hazard. Although my vehicle is slightly outside the settlement mileage and time limit, timing chains are considered a lifetime component and are not a maintenance item, meaning they are not expected to fail and are not listed as requiring inspection or replacement under any Audi maintenance schedule. This failure was sudden, catastrophic, and safety-related. Audi and Volkswagen have already acknowledged this timing chain defect in federal class-action litigation (Opheim et al. v. Volkswagen Group of America), and my VIN is included in the affected vehicle list. Audi’s own dealership technician confirmed that the timing chain is stretched, the tensioner is fully extended, and the intake camshaft timing is off by a tooth—clearly matching the known defect. The vehicle stalled suddenly while arriving at a repair facility, and it would not restart. Had this occurred on a highway, a collision could have easily resulted. This is a known safety defect, affecting engine timing, power loss, and stall risk. The manufacturer denies responsibility despite known defects, safety implications, and VIN eligibility. I am requesting NHTSA to investigate Audi’s refusal to address a known and documented safety-related defect involving a critical non-maintenance engine component that is expected to last the life of the vehicle.

Hi My name is [XXX] and I have an 2014 Audi A4 that has been consuming to much oil ever since I bought it . I see the vehicles contained defective pistons that caused excessive oil consumption. Can you please help with this ? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EXTERIOR LIGHTING

The third brake light intermittently stops working. Being that it is intermittent, it tells me the led and circuitry are working. Also, a warning alert will illuminate on my dash instrument cluster and not when the light is working again. Upon further searching on-line, there is an issue with a solder joint cracking. I believe this is the case because when i jiggle the connector, the light will illuminate. Since this light is required by law, this is a very important safety issue. And a rather expensive one since the replacement part alone is $150-$200.

ENGINE

Heating/ cooling system is not functioning correctly, continues to get warning meage from car heating/coolant warning, and engine coolant is leaking out

ENGINE

Loss of power / Turning onto oncoming traffic there was severe hesitation. Which caused the car to not move onto oncoming traffic quick enough causing both oncoming vehicles to maneuver around. Upon going to the mechanic he states I have oil in the engine from faulty piston rings which he states he has seen multiple times in these models.

UNKNOWN OR OTHER

I was driving down the highway and my sunroof suddenly exploded randomly. No signs of anything hitting it at all.

ENGINE

With out warning vehicle engine shut down in the middle of the highway causing loss of power to breaks and steering. Mechanics assessment states engine is mechanically or electrically blocked. Upon investigating issue I found numerous law suits regarding engine piston failure. Please see civil action docket number L-001632-21. Found on class action .org

I've purchased this out of state, in 2017 December. The place was an Audi Dealers Belle Audi , in Elizabeth, New Jersey. I bought an extended on the paint and they failed to cover it when it was peeling, I since had the hood repainted, had a recall Fuel pump ( after run) , and steering column repair hbut at around 85,000 miles I saw an add oil light on my dash that indicated I needed oil, and then a service engine light- so I took it to South Burlington Audi in Vermont for a servicing and they said all was okay. Every servicing I've had done on it was at that dealership. They changed the oil/ filter etc.. but came accross as nothing was wrong when I asked and I was told - are you sure you need oil? and the girl who worked in their service department said to bring it by, and I did just 2 weeks later after the servicing that light came on again, She added a half a quart in the area I parked in. She said its fine and I left. Next thing I went buy 2 other times reporting it and their was only a sales agent and a man who worked in the Manager for servicing is english/autralian accented told me to just add oil. Then yesterday I went back after I was told on Monday evening this could be a breather valve. Well Audi has an issue with piston seals being bad- causing this and ever 150-200 miles I need to add a half a quart- and if not my engine light comes on. I've had 2 mis-fires and they told me up to 100,000 miles the class action suit covered- and they deliberately ignored this so they did not have to tear down my engine and fix the oil consumption issue. There was oil on the botton in one small area and on top, I had to fill it on the highway it blew oil over the top while filling I explained ,so they did a dye test and cleaned it and no oil leaks shown. They refused me a repair covered under the defective piston / ring/ seal class action suit 3 times. I would like to report them and file a law suit. Can you refer and assist me in this. It is an 2014 A4 2.0 Turbo.
