I was driving my Audi when I got transmission malfunction light on along with suspension fault and epc light and check engine light all together and the car wouldn’t go faster than 20 mph. Causing someone to rear end me and them fleeing . So not only was my car hit because of this but I had no driver to hold responsible for the damage

Was just driving down the highway at normal speed and my car lost all power, every like came up on the dash and disabled my power steering causing me to almost crash. Took it to the shop mechanic tells me the turbos failed due to oil screen and it will cost me $8,000 Not sure why they failed I have amazing service records on my car. This needs to be a recall.

I noticed my car wouldn’t engage in reverse when shifted so I took it in for a transmission flush and it was performed and 2 days later I got a light on dash saying transmission overheating . And the car completely lost power while on freeway and went from 60 to 20 miles per hour and will not shift past first gear . So I took it back in to dealer paid diagnostic fee and then was told my transmission was bad and had to be replaced and was quoted a price of 15683$

I PUT MY CAR IN REVERSE GEAR AND THEN PRESSED SLIGHTLY ON THE GAS PEDAL. THE CAR DIDN'T MOVE. I CHECKED MY HAND BRAKE AND REGULAR BRAKE. BOTH WERE DISENGAGED. SO I PRESSED A LITTLE MORE AND MORE. THE ENGINE BEGAN TO GROWL LIKE CRAZY AND THE CAR REFUSED TO EVEN MOVE. THEN ALL OF A SUDDEN THE CAR JUST LAUNCHED ITSELF. I NEARLY HIT ANOTHER CAR. IT WAS VERY SCARY. I SWITCHED THE CAR OFF AND THEN TRIED AGAIN. THIS TIME NO TROUBLE. SIMILAR THING HAPPENED WHEN I WAS EXITING A PARKING LOT. FIRED MY CAR UP, PUT MY CAR IN "D". PRESSED ON THE GAS PEDAL. CAR WOULDN'T MOVE. PRESSED MORE AND MORE, NOTHING !! THE ENGINE WAS GROWLING LIKE CRAZY ALL THIS WHILE. THEN SUDDENLY THE CAR LAUNCHES ITSELF LIKE CRAZY. I ALMOST HIT ANOTHER CAR COMING FROM THE OPPOSITE DIRECTION. AGAIN, WHEN I SHUT DOWN THE CAR AND SWITCHED IT BACK ON IT SEEMED TO WORK FINE. THIS HAPPENS VERY OFTEN.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2013 Audi S6 verdict →
