“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: [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…”

“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.”
“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…”
