Electrical system

2 reports1 fire
“After water damage to the bottom level of the seat an electrical fire started. It burned through and melted the plastic facing on the right side of the seat near the seat adjustment mechanism releasing toxic fumes we have so far been unable to abate. The manufacturer has been unresponsive in addressing this hazard. The damage is available for inspection. The toxic fumes are a health hazard as was the fire. The dealer inspected the damage and refused to repair it. The Bureau of Auto Repairs in California also inspected the damage. There were no warning lights activated.”

Power train

2 reports1 related recall
“MINE IS A WELL-MAINTAINED, NEAR-PRISTINE, LOW-MILEAGE CAR. WITHOUT WARNING OR PRIOR INDICATION OF A PROBLEM, THE TRANSMISSION SUDDENLY CEASED TO OPERATE CORRECTLY WHILE TRAVELING ON A BUSY, FOUR-LANE URBAN HIGHWAY. IT RESULTED IN THE CAR HAVING LIMITED FORWARD MOTION, POOR CONTROL, AND VASTLY DIMINISHED POWER, MAKING IT EXTREMELY DIFFICULT TO MANEUVER IN TRAFFIC. I NARROWLY AVOIDED A COLLISION WITH OTHER CARS. I MANAGED TO DRIVE THE CAR BACK ABOUT 20 MILES TO MY RESIDENCE IN THE LIMP-HOME MODE--ONE FORWARD GEAR, THE ENGINE REVVING BETWEEN 3000 TO 5000 RPM'S WITH THE FORWARD SPEED NO MORE THAN 35 MPH. I PARKED THE CAR AND LEFT IT FOR A WEEK WHILE TRAVELING. WHEN I RETURNED IT WOULD NOT MOVE IN ANY GEAR. I HAD IT TOWED ON A FLAT-BED TRUCK TO AN AUDI DEALER. THE PROBLEM WAS DIAGNOSED AS AN INOPERABLE, UNREPAIRABLE TRANSMISSION BROUGHT ABOUT WHEN "A BOLT SEPARATED FROM THE TRANSMISSION HOUSING CAUSING A HOSE TO LEAK TRANSMISSION FLUID WHICH RESULTED IN BURNT PARTS AND GEARS. THE COST OF A NEW TRANSMISSION WAS $6,800--ON A CAR WITH ONLY 50,546 MILES! AFTER REPORTING THE INCIDENT TO AUDI CORPORATE, I WAS INFORMED THAT AUDI COULD NOT BE HELD RESPONSIBLE FOR THIS EVENT…”
