We, a group of Audi S6 owners with vehicles from the 2013-2017 model years, are experiencing premature mechatronic issues. These problems manifest as jerking when coming to a stop, which can lead to accidents, and intermittent power loss that can be life-threatening. These issues began around 40,000 miles and have progressively worsened, despite our vehicles having only approximately 70,000 miles on them. Given the early onset and severity of these problems, we strongly urge a recall. The current mechatronic design appears to be flawed and fails prematurely, posing significant safety risks.

I am having a transmission malfunction warning light on the dashboard that comes on. The car will not shift gears which is dangerous when driving in streets/highway. This is a known issue with the Audi S6 and related models and a class action lawsuit is in process. Audi is trying to charge few thousands dollars $8000-$12,000 to replace the mechatronic and clutch transmission system which is very prone to failure. Thank you

THERE IS SOMETHING WRONG WITH THE WAY THE S6 DOWNSHIFTS WHICH MAKES DRIVING UNSAFE. A DOWNSHIFT IS FOLLOWED BY ABOUT 1 SECOND OF THE TRANSMISSION NOT BEING ENGAGED (SO NO POWER TO THE WHEELS) AND THEN SUDDENLY THE TRANSMISSION ENGAGED AND THE CAR VIOLENTLY THRUSTS FORWARD. THE ISSUE IS MORE PROFOUND WHEN DOWNSHIFTING 3RD TO 2ND AT ABOUT 20-30 MPH AND CAN RESULT IN REAR-ENDING THE CAR IN FRONT. APPARENTLY MANY S6 OWNERS FACE THE SAME ISSUE. AUDI HAS FIXED IT IN 2013 MODELS WITH SOFTWARE UPDATE BUT THE ISSUE HAPPENS AGAIN IN THE LATEST MODELS.

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 2016 Audi S6 verdict →
