The engine failed while I was driving. The car did not show any warning lamps, messages or other symptoms, it just jumped and died. I had the car towed to my mechanic. The mechanic thought it was the starter, but then realized the chain had broken and it hit other parts of the engine, including the pistons catastrophically. The engine is not reparable. My safety was a risk as the car died on a busy road. Audi has asked that I bring the car, at my expense for them to inspect, without offering anything. I have a letter from them indicating that they will not help. ABS SYSTEM and Brake Actuator that is failing or defective. Vehicle was taken to the dealer but was not repaired.

The battery failed/malfunctioned and was leaking hydrogen sulfide gas into my car slowly for a long period of time. A month or two after I initially financed this used Audi A4 at Volkswagon in Dothan, AL, I started experiencing the side effects of low dose exposure to hydrogen sulfide gas. From that point until today my symptoms have been getting worse and worse. My asthma symptoms progressed. I caught walking pneumonia several times. My hair has been falling out in clumps and my kindneys are having serious issues. My pee started smelling very strange. Consistently, over the past year and a half, I have nearly passed out at the wheel of my car over and over. For a very long time, the gas was odorless and really couldn't be detected by smell. Five days ago I went to start my car and it wouldn't crank. I jumped it off and for the next five days following that the smell of rotten eggs got worse and worse....I'm lying in the bed right now bc my lungs feel like they're going to explode. I've felt this, along with my heart feeling like it was going to explode put of my chest, as well as my entire stomach/intestines feeling as if someone were stabbing me with knives. My doctors could not figure out why all of my hair was falling out or why I started to develop peripheral neuropathy. They even ran tests on me for Multiple Schlerosis. Found nothing. They did electrical pulse tests and cat scans and my dermatologist had no explanation for my hair just falling off my head in handfuls. I have a third of the hair on my head that I used to have. My skin and eyes consistently kept getting irritated by the gas as well....splotchy red exema like patches appeared all over me. I had a miscarriage because of this as well. I couldn't afford to get the car looked at, so it hasn't been taken anywhere. I received no warning of the problem until two days ago when my lights in my car and the air conditioner stopped working. The year of my life had been a living hell.

ISSUE WITH POORLY ENGINEERED WATER PUMP. MY WATER PUMP WENT OUT DUE TO A SMALL PLASTIC SEAL MALFUNCTIONING AND ALLOWING COOLANT TO EXPEL FROM SYSTEM. I AM FORTUNATE I LEARNED OF THE ISSUE UPON STARTING MY CAR AND COULD IMMEDIATELY TAKE CARE OF IT, ALTHOUGH LEAVING WORK AT 9PM, LONG AFTER EVERYONE HAS LEFT AND WITH NO AUTOMOTIVE SHOPS OPEN MADE IT DIFFICULT TO TAKE CARE OF. UPON TALKING WITH AN INDEPENDENT AUDI/VW SPECIALIST AND DOING MY OWN RESEARCH I CAME TO FIND THIS WAS AN INCREDIBLY COMMON PROBLEM. MY CAR HAD ONLY 35K MILES ON IT AND WAS 1 MONTH OUT OF WARRANTY WHEN THIS OCCURRED. THE AUDI/VW SHOP SAYS THEY REPLACE 4-5 OF THESE PUMPS PER WEEK! IT CLEARLY IS A MAJOR ISSUE, ESPECIALLY SINCE A CAR CANNOT FUNCTION AND IS DANGEROUS TO OPERATE WITHOUT THE COOLING SYSTEM. I WAS VERY UPSET THAT THE AUDI BRAND WOULD ALLOW A KNOWN PROBLEM TO CONTINUE, AS IT DOES NOT SEEM LIKE A 'LUCK OF THE DRAW' PART MALFUNCTION.

THE CAR BURNS TOO MUCH OIL, NEED TO ADD 1 QUART EVERY 700-1000 MILES. THERE IS NO LEAK BUT THE OIL BURNS AND YOU CAN SEE THE EXHAUST PIPES ARE BLACK. IT SEEMS THIS WAS A PROBLEM IN 2011 4 CYLINDER AUDIS AND IT WAS ADDRESSED BY AUDI.
