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.

The timing chain and tensioner in my 2014 Audi A4 Quattro (VIN: [[redacted]] ) 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.

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.

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.

This vehicle is needing a quart of oil every 300-400 miles. It's a 6 year old car, there is something seriously wrong with audi engine design. A quart of oil every 300-400 miles is completely unacceptable. Since day 1 this vehicle has had an oil consumption problem now at 75k miles and the problem just continues to get worse.

I took my car to the audi service center and they expressed to me that my engine coolant pump was not working and that it had to be replaced. However, they did not tell me it was apart of a recall. Had I known this, I feel as though I should not have been charged approximately $2,300 to get it fixed when it was recalled from something out of my control.

My car started burning oil much more frequently after it hit 120k miles. The light would come on to add a quart of oil every 1500 miles. The car now has 145k miles on it and the oil light comes on after 500-600 miles, which seems much too frequent. The car is only 6 years old and I would expect it to last another 50k miles but I'm concerned that there's something wrong with the engine that's causing it to burn so much oil so quickly. *Tr

the epc light came on. I have spent thousands of dollars on repairs, car rentals, rideshares and replacement parts for the same thing over and over. I am not sure what recourse I have but I need assistance. The 1st time audi replaced the engine and 7 months later it happened again so they replaced the gas pump, 1 year later the same thing happened and they wanted me to pay for another gas pump because the warranty ended. Then its been repaired twice by another mechanic for the exact same thing.

4 Year old car 3 months past 4 year extended warranty and major oil leak, which if not repaired can negatively impact engine. Both valve cover gaskets and timing chain cover gaskets are leaking. When asked service consultant at audi how often this happens, he said in 15-20% of cars by 50,000 miles (i have 46,000 +). This is a manufacturing flaw and should be made part of a recall. I am paying over $2000.00 For this repair after a 10% discount with a dealership "coupon". This is clearly a manufacturing defect of...

these parts and it is inexcusable that audi pass this defect and the costs on to 15-20% of customers after approximately 4 years of ownership and comprehensive maintenance . The service person told me there was nothing I could do to have prevented this from occurring . I think the ntsb can alert audi to the . Fact this is a defect in the cars they are selling, causing unnecessary costs and burdens and possible engine hazards to consumers.
